need information on openings in b.a.s.e
#Alex13 posted a topic in BASE Jumpinghello everyone ! I am a parachutist and I plan to start the b.a.s.e. But one question is holding me back... I've been working in construction for a long time and my back isn't very young... I tolerate traditional parachute openings and I wanted to know if b.a.s.e openings are much more violent? High slider? Slider down? compared to skydiving? Thank you in advance for your answers ! good jumps Alex
Useful Training for BASE, Right There on the Dropzone
admin posted an article in DisciplinesCourtesy Apex BASE: Pascal Constantineau flying his FLiK at Skydive Perris during his BASE canopy course with Dimitrije Dadic. (Of note: Square1 offers discounted rental rigs to people taking Dimitrije’s BASE canopy courses.) If you’re like most people, your idea of dropzone training for the stresses of the BASE environment involves trying to look nonchalant when you climb into a hot-air balloon basket. If you have no access to such a thing (and/or if you’re significantly smarter than the average bear) you’re probably looking for more. You know you need a way to get as many jumps under your belt as possible with your BASE parachute proudly overhead--preferably, with a reserve on standby. But how? “Skydiving your BASE canopy is by far the best way to learn canopy skills for BASE jumping before making a BASE jump,” says Steve Doherty, who served as Director of Operations of Apex BASE for five years. “In a perfect world, everyone would be able to jump their BASE canopy skydiving--a lot--before they ever took it out on a BASE jump.” Ideally, if you’re serious about this, you’re not just swapping gear willy-nilly on every dropzone day. You have a dedicated skydiving system, configured for the purpose. Here’s how to build it. The Canopy“It's only with the introduction of ultralight canopies that jumping BASE canopies at the dropzone has become a possible and useful activity,” he continues. “Anything you can use in the BASE environment, you can use in the skydiving environment--of course, in the skydiving environment, you have to manage your opening speed.” “If you take your whole BASE setup: mesh slider, BASE bridle and BASE pilot chute, you're going to have a very brisk skydiving opening,” he adds. “In our collective experience at Apex, we found that you can make two or three slider-up skydives on this kind of setup in a day and it's okay. If you were going to make five to ten, you need to start making modifications.” As any seasoned BASE jumper will tell you, nothing flies quite like an actual BASE canopy--so the goal is to get as close to it as possible. Athletes who want to train BASE canopy skills should choose an ultralight canopy and seek a skydiving container that fits it. That said: Athletes who want to get into flying a wingsuit with the intention of BASE jumping but don’t want to jump a BASE-sized canopy for all their wingsuit skydiving training now have some options.“On today’s market, you can find seven-cell, BASE-type canopies created for the skydiving environment. The benefit is that--while these canopies do have some of the distinctive BASE properties--you can jump all day and not feel it when you wake up the next morning. The RisersForward-facing risers are more appropriate in the skydiving environment for a simple reason: the possibility of a horseshoe malfunction. During a horseshoe malfunction, forward-facing risers are the only type that you can reliably cut away. “During a horseshoe malfunction with rear-facing risers,” Doherty notes, “Your body will be in the way of the twisting movement that the three-rings need to do in order to release. So, when you’re jumping a two-parachute system, we always recommend jumping forward-facing risers.” The ContainerAs you’ve certainly noticed by now: Apart from student gear, most of the containers available for sport use won't fit BASE canopies. According to Apex, the best way around that is to jump an ultra-light parachute. (Take, for instance, the Lobo: a 250 can pack up to the size of a skydiving 180.) “More and more drop zones are coming around to the idea of BASE jumping,” Doherty continues, “That is to say: Not assuming that it’s attracting bad publicity to the sport of skydiving. Nowadays, they're more willing to let their student gear be used. Here in Southern California, we suggest going to Square One. They have a huge selection of demo equipment, so it’s relatively easy to get the largest demo container they have and pack into it the largest BASE canopy that fits.” Most drop zones have a container that's sized for a 180/200. The Apex team have, however, not been able to find a non-tandem or -military container able to fit anything bigger than a 300+ made from F-111 fabric. (UltraLite PN-9 is a different story, and large canopies are more easily accommodated.) The D-BagTalk to your local CReW dogs: You don't have to use a deployment bag when you skydive. “You can free-pack your BASE canopy into a properly-sized skydiving container, just like you do in your BASE container,” he says, “except the rectangle is a lot smaller, so you’ll have to stack it up.” If that sounds a little unnerving, ask for help. Doherty notes that a lot of the older generations of CReW skydivers are quite familiar with that deployment method, so ask them for advice. If you do use a D-bag, he insists that you’re using it correctly. Take note of what BASE canopy you're using. Not all BASE manufacturers use a metal ring at the top of the parachute. Some do use a metal ring, just like you'd find on a skydiving canopy. The Blackjack and Ace canopies built by Asylum also use a metal ring. Atair doesn't. And Apex doesn’t, either. To get this right, use a metal connect link to prevent the canopy from getting sucked up into the grommet of the bag. (Very importantly, the link needs to be inside the bag.) The Pilot ChuteYou are going to want to use a slightly larger pilot chute for a BASE canopy than you would if you were jumping a skydiving canopy, because the BASE canopy itself is much larger. “You don't need to use the same-sized pilot chute that you use in the BASE environment,” Doherty notes, “We recommend a 32" non-collapsible pilot chute for skydiving. It's much larger than a sky pilot chute, which is typically 28 inches.” The Bridle“We typically use a longer bridle in BASE jumping,” Doherty says. “You don't need to take the BASE bridle over to make the BASE canopy work. You'd want to use the bridle that was appropriate for whatever discipline you were doing in skydiving. We recommend using a normal skydiving bridle for normal skydiving freefalls. If you’re wingsuiting, we recommend using whatever bridle length you'd normally use for wingsuiting in the BASE environment.” The SliderYou can use a mesh slider, but it’s not ideal. “In BASE, we’re so close to the ground that we tolerate--even welcome--brisk openings,” Doherty says. “But if you make five jumps on a mesh slider at terminal, you’re going to feel it. You won’t regret using a sail slider in the skydiving environment. That said: If you’re making hop-and-pops, a mesh slider is not a problem.” The JumpsOnce you’re all geared up, there’s only one place to go: Up. And when you get there, you’ll have a few more things to think about. “When you're jumping a BASE canopy on the dropzone, you have to think about where you're going to be in the pattern,” Doherty advises. “You're jumping a parachute that's much larger than the other parachutes around you and you're going to descend a lot slower. Especially at large dropzones where they’re flying multiple aircraft and doing multiple load drops over the same area, this can get problematic. Stay out of the way.” The MentalityIf you have access to a candy-colored, fire-powered dead-air machine, then by all means use it--but don’t rely on them as the sole training platform for your BASE-jumping skills. Commit to fine-tuning your BASE canopy skills (and that impossible-to-exaggerate-the-importance-of accuracy) before and between jumps from objects. Your bones, your friends and your family will thank you. And--as always--talk to your mentor and/or gear manufacturer to clarify any points that leave you unclear.

Introduction: We have all seen the amazing videos of people like Robert, Yuri and Loic flying their wingsuits. It is natural to want to follow in their slipstreams but let us make sure we do so safely and with adequate preparation. This document is intended as an initial information source for BASE jumpers interested in starting wingsuit BASE. This document is not an instruction manual. It does not contain rules, only advice. Wingsuit BASE is more dangerous than normal BASE jumping if the jumper does not conduct adequate preparation. If you choose to pursue wingsuit BASE you are strongly recommended to seek instruction from an experienced wingsuit BASE jumper. There is no substitute for one to one coaching. A wingsuit allows for incredible freefall delays and horizontal distances to be achieved, almost eliminating the chance of striking the object you jumped off, the number one cause of BASE jumping fatalities. But jumping a wingsuit also has some serious drawbacks: The wingsuit restricts your physical movement making exits harder to perform i.e. difficult to climb down to the exit point, easier to go unstable and then harder to recover. The wingsuit complicates deployment and prevents you from controlling your canopy immediately after opening. The wingsuit jumper must carefully assess the terrain he intends to fly over as the eventual opening point and landing area will be different than for a normal BASE jump and will also depend on flight performance. Experienced BASE jumpers who use ground rush as an altitude indicator must exercise caution during their initial jumps. The low fall rate and high horizontal speeds can fool the jumper that they are higher than they actually are. The wingsuit ground rush for a minimal canopy ride is a lot less intense than for normal freefall. The wingsuit jumper must also pay attention to his altitude when flying down a talus or over sloping terrain. The jumper often focuses on the airspace they are flying towards, giving the illusion they have lots of altitude available (e.g. looking at the valley floor in front of them). In this situation the jumper must remember that the critical altitude is the immediate vertical elevation they have over the talus or slope. The wingsuit jumper must always ensure sufficient altitude for a safe deployment - bear in mind that as soon as the PC is released the wingsuit jumper will stop flying and drop vertically approx. 200’+ as the canopy deploys. Experienced wingsuit BASE jumpers may attempt to make jumps that would be otherwise impossible without a wingsuit. The jumper must be absolutely sure of his own capabilities and those of his equipment when undertaking jumps that allow little margin for error. 2. Before even considering doing a wingsuit BASE jump you should be: An intermediate BASE jumper: With minimum 50 BASE jumps (but more jumps are strongly recommended!) Cool under pressure, very comfortable in the BASE environment Always performing solid exits, also when exiting with arms by your side Have good sub & terminal tracking skills Have excellent canopy flying skills and landing accuracy Have consistent record of stable deployments and on-heading openings An intermediate wingsuit skydiver: With minimum 50 wingsuit skydives (but more jumps are strongly recommended!) Who wears a wingsuit as if it were pyjamas, not feeling physically restricted by the fabric Always able to find the PC quickly and cleanly, with good on heading openings Well practiced at recovering from instability Able to unzip arm wings instantly after deployment - like 2nd nature Familiar using arm and leg cutaways in freefall and under canopy immediately after opening Able to fly the suit comfortably without “potato chipping” achieving reasonable fall rate and forward speed Ideally have performed some wingsuit balloon jumps to simulate the exit & sub terminal flight See Appendix B for specific flight drills to practice whilst jumping the wingsuit from the plane. A person who has read all the incident reports, analysed the contributing factors and accepted that wingsuit / BASE jumping is worth the risk of serious injury & death. 3. So you still want to wingsuit BASE? Let’s talk about specific preparation: Equipment: First thing, it is strongly recommended to start wingsuit BASE using a low performance wingsuit i.e. Birdman Classic, GTi or similar. Once you have 10+ good wingsuit BASE jumps you could consider jumping with a higher performance suit. The following items are strongly recommended: A 1 or 2 pin BASE container for wingsuit BASE. The high speed airflow over the container and high deployment angle excludes the use of a Velcro rig. A normal terminal pack job i.e. symmetrical, mesh slider packed “up” (large or fine mesh depending on personal preference). ZP pilot chutes, the size depends on your canopy, between 34” – 38”. The PC should NOT have a hackey handle (or heavy handle). With a hackey PC handle there is the possibility of the bridle wrapping around the base of the handle. A heavy PC handle could contribute to PC hesitation. The following items are recommended: A container with “dynamic corners” or open corners. A suitable helmet, goggles and low profile protective pads. Back to the dropzone: Perform 20 hop-n-pops using your low performance wingsuit and a sensibly sized 7 cell main, or even better your BASE canopy in a skydiving rig. (The 20 jumps can count towards the 50) Work your deployment altitude gradually down to USPA minimum of 2200’, open by 2000’ (Discuss this with your CCI / DZO first, some dropzones may enforce a higher pull altitude) If you have any instability, deployment or opening problems go back to full altitude jumps until they are rectified, use a BMI if necessary. During these 20 hop-n-pops think about your emergency drills for the following situations, bearing in mind the reduced altitude and time under canopy: Unstable exit Handle inside of pouch /BOC Hard pull Floating handle PC in tow Premature deployment Horseshoe malfunction Line twists Line over Water landing Jammed zip Now to a far away land: It is strongly recommended to go to one of the following well known “high” locations for your first wingsuit BASE jumps. Become familiar with the object performing normal BASE jumps, getting to know landing areas and outs, obstacles, rock drop, winds, talus / ledges etc. Site Pro Con Carl’s Huge wall in Northern Norway: Good vertical rock drop Huge LZ Good access Not many sheep and it rains a lot Norwegian Fjord in Southern Norway: Good vertical rock drop Medium sized LZ Good access Very expensive beer Italian Terminal wall: OK vertical rock drop Small LZ (assume Heli LZ) Good access Wind / turbulence can be a problem Swiss Fungus: Good vertical rock drop Large landing area Access is difficult, requiring high fitness level and basic climbing skills Once you are comfortable with the site, pick a day when you are feeling 100% and the weather conditions are perfect to make your first wingsuit BASE jump. Advice for your first wingsuit BASE jump. What to focus on? Being current! Make sure you get current at wingsuit skydiving and BASE jumping in the weeks running up to your first jump. Pack yourself a nice terminal opening, attach the wingsuit correctly with the PC packed in the BOC with the correct tension (not too loose or too tight). Perform a full gear check before the hike, avoid “exit gear fear” syndrome, as you will already be under pressure. Exit in a nice head high position, student style, with you arm wings open and your leg wing closed, your arm wings will help you balance and remain head high. 1-2 sec after exit slowly extend your leg wing and start to trim the suit as you feel the air speed picking up. Premature exposure of the leg wing can cause you to go head low – be warned! Better to be head high. If you should go head low, stay calm! Bring your head up and if the object allows it, try to stay parallel with the surface and build up some speed to allow you to pull up out of the dive more easily. You may wish to consider this possibility when selecting the site of your first few wingsuit jumps. After you have extended the leg wing focus on flying the suit efficiently away from the object pulling nice and high – don’t rush, take time to reach, grip and throw the PC. The PC throw should be vigorous to clear the burble the suit makes behind you. Remember to keep your body symmetrical at all times during deployment to help maintain on heading performance. It is recommended to learn to deploy from full flight as the BASE environment rarely allows enough altitude to collapse your wings and fall vertically prior to deploying. This also has the advantage of keeping the airflow over your body fast & clean reducing the chance of pilot chute hesitation. Deploying from full flight implies keeping your leg wing inflated and only collapsing your arm wings for the moment required to locate the PC. As your canopy reaches line stretch it is better to close your leg wing as it can catch air causing your body to twist. Your first 5 - 10 jumps should focus on a stable exit, flight and deployment, once you have these survival skills you can start to think about flight time and distance. 4. You now have some wingsuit BASE experience, what’s next? Once you have become a competent wingsuit BASE jumper you could consider: Jumping a higher performance suit Jumping from lower objects, for example the higher exit points in the legal Swiss valley. Jumping camera Performing 2 ways + Opening up new objects Aerials Your imagination is the limit! Make sure there is video! Note: Trying to land any of the current wingsuit designs is only recommended for the terminally ill. You want to jump a higher performance wingsuit: So you have done approx. 10+ good wingsuit BASE jumps with a low performance suit and you now intend to jump a higher performance suit. Assuming you have trouble free experience flying the higher performance suit from the plane you can go ahead and use it for BASE. Treat your first wingsuit BASE jump using the higher performance wingsuit the same as your first wingsuit BASE jump. You want to jump a wingsuit that has a leg pouch PC: If you intend to use the leg pouch PC (e.g. S3 or Phoenix Fly wingsuit) - it is strongly recommended to perform the following ground and skydiving preparation. Prior to jumping the leg pouch PC perform a couple of thousand practice pulls on the ground. Be able to find the handle, regardless of body position with your eyes closed. Do 300 practice pulls a night for a week or so, simulating full flight then deployment. When packing the PC into the leg pouch assure that the Birdman or Phoenix Fly guide lines are followed. The PC should not be too loose or too tight. It is strongly recommended to bar tack the Velcro sleeve to the bridle - check that you leave enough free bridle between the bar tack and pin to ensure the Velcro is completely peeled before any tension is applied to the pin. Failure to do so can cause PC hesitation. Don’t mate the male-female Velcro over each other 100% when the suit is brand new, let the them overlap 50% to the side for the first few dozen jumps until the Velcro is slightly worn. For more details on assembling and packing the leg pouch PC system please refer to http://www.interone.net/learn/basepc.html. Perform at least 10 skydives with the system, using a wingsuit or BASE bridle, start with normal altitude jumps, performing dummy pulls in flight and then pulling high to give yourself extra time. Assuming you have no opening problems or issues finding the PC handle quickly & easily you can work down to lower altitude deployments. Treat your first wingsuit BASE jump using the leg pouch the same as your first wingsuit BASE jump. 5. Conclusion Following these guidelines does not make wingsuit BASE jumping a safe activity. Wingsuit BASE is still a relatively new discipline. It requires jumpers to develop new skills, new muscle memory, new judgement and new understanding. Respect it. This document is by no means the final word on wingsuit BASE jumping, always seek advice and guidance from other experienced wingsuit jumpers and share what you discover. By taking part in this activity you are in effect a “test jumper”, we all still have a lot to learn…. Let’s be careful out there Long Flights Contributors: James Boole Craig Poxon Robert Pecnik Simon Brentford Gray Fowler Yuri Kuznetsov Steve Schieberl Per Eriksson Disclaimer: The authors of this document accept no responsibility, financially or otherwise for any loss, serious injury or death that occurs as a result of any persons following the advice contained within this document. BASE jumping and wingsuit BASE jumping are extremely dangerous activities carrying risk of serious injury or death. Performing the activities described in this document with out becoming an expert skydiver and completing dedicated BASE / wingsuit training will likely result in a demonstration of natural selection. Appendix A Specific wingsuit drills to perform whilst jumping from the plane: Barrel rolls Front flips Back flying Flying and pulling with left arm wing closed (i.e. to simulate blown wing) Pulling out of steep dives quickly (i.e. bad exit) Dropping knees Turning with minimal altitude loss Carving turns Arching, de-arching Deploying from full flight Flying with one bootie off Turning only with legs Turning only with arms Appendix B – Wingsuit fatalities #67 Kirill Kiselev, September, 2002 Age: 27, from Ekaterininburg, Russia. Cliff Jump (Wing Suit) Vikesaxa (Eiksdalen Valley) Norway Impact I received this report from a close friend of Kirill who witnessed or heard most of the jump. Kirill has 500 skydives with 20 being with a wing suit, and 30 BASE jumps, with 2 being with a wing suit. This fatality began with an inadvertent low pull from a man who didn't do low pulls. His friend believes Kirill encountered a stability problem late in the flight. The friend, along with authorities, inspected Kirill's body and gear at the hospital. Kirill had opened his canopy, the slider is at the links. Both toggles are still stowed. The wing zippers are closed and the swoop cords are still over his fingers. The wing fabric between his legs is torn. His broken neck and one broken leg suggest opening and impact occurred at about the same time. The report intimates failure of the wingsuit material between Kirill's legs caused a stability problem at pull time. By the time Kirill stopped trying to overcome the situation and deploy, it is too late. Kirill is the first BASE jumper to die flying a wingsuit on a BASE jump. #68 Rob Tompkins, September 12, 2002 Lysbotn, Norway Cliff Jump (Wing Suit) Kjerag Impact This is the second wing suit BASE fatality. Rob has 247 BASE jumps with 92 being with a wing suit on the day he died. A report states: "For the last month, Rob had his eye on a particular jump between launch points 4 and 5. We looked at it, doing rock jumps and basically studying the jump. There are two launch points next to this particular jump, one with a 7-second drop and the other with an 8-second drop. Rob jumped the 7-second launch point 10 times always doing a reverse gainer. The place he's looking at now, he dubbed the, "RT Hjørner," and has a rock drop time of 5-seconds. We analyzed this site on video and with other wing suit pilots. In my opinion, the jump is not achievable - and I repeated this to Rob. Other wing suit pilots said the same thing. Rob is convinced he can do it including a reverse gainer. After 7 seconds of freefall Rob impacted the talus ledge. He never tried to deploy his pilot chute, knowing that this would not save him. Rob believed he could out fly the ledge right up until he died. Rob is remembered as a good man, full of respect, and kind to everyone." #69 Lukas Knutsson, October 11, 2002 Cliff Jump (Wing Suit) Engelberg, Switzerland (Cold Steel) Impact Lukas has a good launch and good flight with his wingsuit and pulled high over the landing area. This is the third BASE wing suit fatality. Despite a powerful pull the pilot chute ended up in the turbulence behind him. In the burble the pilot chute spun around very fast. Lukas notices the deployment is hesitating and collapsed his wings and rolled to one side to clear the pilot chute. At this point the pilot chute achieved bridle stretch but the bridle had entangled with the pilot chute so badly the pilot chute is almost totally collapsed. Lukas did rollover to the other side and struggled hard to get the canopy out of the container. However, the container remained closed to impact. Lukas is a very experienced long time BASE jumper (this site is now called "Cold Steel" in his honour) and he will be missed by the entire BASE community. #75 Gabi Dematte, August 13, 2003 Cliff Jump (Wing Suit) Gasterntal, Switzerland Cliff Strike & Impact The following report is from one of Gabi's many friends. "Gabi went to jump alone, like she did very often. Getting away from the crowds in Lauterbrunnen she went to another valley known by only a very few jumpers. She couldn't out fly a ledge with her wings. Which is awkward, because she kicked ass with those wings. She did not attempt to pull. Gabi was a very good jumper, and a super nice person. I was lucky to get to know her and I will treasure her contribution to my existence. For me, it was nice to jump with another woman. It was special and it did not last long enough. Lauterbrunnen valley is empty and quiet now." Gabi is the fourth BASE wing suit fatality." #80 Jeff Barker, July 5, 2004 Age: 32 Cliff Jump Mount Baker-Snoqualmie National Forest Impact Jeff is jumping with a wingsuit and he failed to clear a outcropping in freefall. #81 Duane Thomas, August 21, 2004 Age: 35 Cliff Jump Lauterbrunnen, Switzerland Impact Duane, a Kiwi with a quick smile, is a well known and experienced BASE jumper. The following is from an eye witness. "The jump is witnessed by two British jumpers and two Swiss jumpers. One Brit watching, and videoing, from the exit point, the other three watching from the LZ. This is Duane's first wingsuit BASE jump, and his first jump ever with a leg mounted pilot chute pouch. Prior to this jump Duane prepared by making 50 aircraft and 2 hot air balloon wingsuit skydives. Duane had a good exit and a good flight. Everybody saw him reach for and locate the pilot chute at what the witnesses said is a reasonable altitude. He then kept his hand there and continued in freefall. The speculation is the lack of normal ground rush (like the type he is used to when not wearing a wingsuit) might have fooled him. The Swiss are yelling at him to pull and he finally did so, at what they said is about 30-feet above the ground. The canopy lifted out of the pack tray but is no where near line stretch when he impacted in a full flight position. According to the Swiss there is no fumbling around, or looking for the pilot chute handle - all the witnesses agree on this. He reached and located the pilot chute, but just took to long to deploy it. A hard pull cannot be fully discounted at this time, but all the witnesses believe he just waited too long." This is the sixth BASE wingsuit fatality since the first one occurred in September of 2002. Reproduced with the kind permission of Nick Di Giovanni #194. The complete list can be viewed at: http://www.basefatalities.info or http://hometown.aol.com/base194/myhomepage/base_fatality_list Other wingsuit incidents: Patrick de Gayardon Geoff Peggs or Dwain Weston Appendix C – Wingsuit site selection You want to open up a new object jumping a wingsuit: So you have become a very competent wingsuit BASE jumper and you intend to open up an object that has never been jumped with wingsuit. Here are some factors to bear in mind. Make sure the vertical rock drop gives you enough altitude to launch the suit and get flying with a little extra in case you have a poor exit. The altitude profile of the object will also affect your decision. Use tools like rock drop, laser range finder and GPS to accurately measure the object. When estimating the horizontal distance that can be achieved from an object remember to factor in the altitude loss from exit and deployment. You may also wish to consider the conditions at the exit point and whether it is practical to put on the wingsuit there. Booties offer little traction when wet or muddy, be careful that you have good ground to stand on for your exit A wingsuit takes several seconds to start generating significant lift and forward speed. Therefore jumping a wingsuit from below 1500’ offers very little benefit in terms of freefall time and object separation (but it adds some colour to the jump).
BASE jumping injuries and treatment in the field
admin posted an article in DisciplinesYou just landed after throwing a double gainer from a cliff in Moab. Adrenaline surges through your system as you think of the amazing visuals you just saw. As you gather up your canopy, you pause to watch the next jumper exit. After a short delay, he tosses his pilot chute and the canopy deploys offheading. He takes evasive measures but the strikes the wall repeatedly. After finally getting the canopy turned away from the cliff, he lands hard on the talus and tumbles to a stop thirty feet below and doesn't move… Now the real adrenaline kicks in. What do you do? Introduction The scenario above is a severe one, but all too possible. In the hazardous environment we know as BASE jumping, we often place ourselves in situations which may result in our injury or death. Due to the inherent risk involved with this activity, every time we jump there is a possibility that something will go wrong. Fortunately, the most common BASE injuries are relatively minor and having a basic knowledge of first aid can help dramatically. With immediate care you can reduce the lasting effects of many injuries, and the time it takes to recover. Another goal is to improve the comfort level of the injured. The scene of an accident is not the place to be thinking about learning lifesaving skills. Preparing yourself ahead of time will make you a more confident jumper and knowing your partners have the same skills will go a long way if you yourself happen to be the one needing help. For the purposes of this paper, I have tried to explain thing in layman's terms wherever possible and assume that you have taken a basic CPR course. (Call the American Red Cross or go to www.redcross.org.) Assessment This is where you size up the situation and the extent of the jumpers injuries. This is a process you will use for serious injuries. Your basic assessment should take about one minute. Not slow enough to waste valuable time, but not so fast that you miss important signs. Your minute will be divided into two phases: the Primary survey or ABC' s (15 seconds), and the Secondary survey (45 seconds). Primary: Establishing the severity of the situation. Make the scene as safe as possible. Move anything that may be a risk to you or the injured and get hysterical people out of the area. Send someone for help. Airway. Make the jumper has an airway. If they can talk to you, they have an airway. If not, check yourself. Use the head tilt/chin lift or a jaw thrust. (These techniques can be learned in a basic CPR course.) Breathing. Are they breathing? Put your ear to their mouth/nose area and look for the chest to rise and fall. If no breathing, revert to your CPR training. Circulation. Do they have a pulse? If not, start CPR. Is there profuse bleeding? Deformity. Are there obvious injuries? Expose. Weather conditions permitting, remove the clothes of the jumper (cut preferably) and cover with blankets as needed. Hypothermia is a possibility now and you need to be aware that the jumper may go into shock. Secondary: Eyes, ears, nose, and mouth: Eyes; in sunlight, cover the eyes then uncover them and see if the pupils react. At night use a light to check. Ears; is there any fluid coming out? Don't try to stop drainage. Nose; any bleeding? Mouth; look for blood or broken teeth. Teeth can be a choking hazard so remove loose, broken pieces. Neck: Can you see any obvious deformities? Chest: Can you see any section of the chest that moves opposite the rest when the patient breathes? (Broken ribs) Is there any tenderness? Abdomen: Is there any tenderness or does the abdomen seem more rigid than normal? (Internal bleeding) Are they trying to keep you from touching them? Pelvis: Any tenderness? Can you feel bones rubbing or grinding? Someone with a broken pelvis will sometimes feel like they're, "falling apart." Arms: Do you see any obvious fractures? Can you feel any bones grinding? Can you feel a pulse in the wrist? Check circulation by pressing on the fingernails and seeing how fast they get red underneath. Try this on yourself for a comparison. Can they feel you touching their hands? Can they move their arms? Have them squeeze both of your hands at the same time and feel if one side is weak. Legs: Do you see any obvious fractures? Can you feel bones grinding? Can you feel a pulse behind the ankle? (Check behind the big ball on the inside of the ankle.) Check the nail beds. Can they feel your touch? Can they wiggle their toes? By now, you should have an overall impression of how severe the jumpers' injuries might be. Now you can plan the best course of action for the rescue efforts. Redo this assessment every 3-5 minutes until EMS personnel take over. Be sure to report these findings to EMS personnel as it will provide useful information to them. For a quick set of field vital signs: Check the pulse and count beats per minute. Approximate blood pressure can be obtained without a stethoscope or BP cuff. A cool trick: If you can feel a wrist pulse, the systolic pressure is about 80. If you can feel a pulse on the inside of the arm where the bicep and tricep meet, it's about 70. If you can only feel it in the neck, it's about 60. Check breaths per minute. This may not mean much to you but if you can provide EMS workers with a sheet of vital signs detailing every five minutes in the past half hour, it can increase your friends' odds of surviving. This is because it shows the "trend" of vital signs and can give valuable clues about the condition of the jumper. Shock Shock can have several different causes but the likely causes in our situations would be trauma to the nervous system, or loss of blood. Shock occurs when tissues and vital organs are not getting enough oxygen from the bloodstream. Symptoms of shock include: Pale, cool, clammy skin Restlessness Nausea/vomiting Rapid breathing Drop in blood pressure The first step in treating shock is to stop blood loss. Then, cover the jumper with a blanket. As long as injuries don't prevent you from doing so, elevate the feet about 8-10 inches over the heart. They may get thirsty but try not to give anything to eat or drink. If there may be a long delay until help arrives, you can give small amounts of water at room temperature. Even if a jumper doesn't display symptoms of shock, treat for shock anyway. They might not be in shock yet. Bleeding There are three types of bleeding: capillary, veinous, and arterial. Capillary bleeding is the oozing blood you see when you skin your knee. It is minor and not life threatening. Veinous bleeding is blood from a vein. It is dark red and flows out of the wound. Arterial bleeding is pretty obvious since there will usually be an arc of bright red blood spurting out of the body. Arteries carry lots of blood and arterial blood loss can be immediately life threatening. Stop the bleeding: Apply pressure directly over the wound. If you have a clean dressing, use it. If you don't have something sterile, use what you have. A shirt or towel will work. If the wound gets dirty, we can treat it with antibiotics later. If direct pressure fails to stop the bleeding, combine direct pressure with elevating the wound over the heart. If the bleeding still hasn't stopped, apply direct pressure to a pressure point. There are eleven pressure points on each side of the body If all else has failed, use a tourniquet. The decision to use a tourniquet is a serious one. This will completely stop the blood supply to the extremity involved and may result in that limb being amputated. Use it in a life or death situation. To apply a tourniquet: Wrap a band around the limb. Preferably, use something flat and at least one finger wide. A strap from a stashbag will work. Tie it in a knot around the limb. Lay a stick or similar object directly on the knot and tie another knot over it. Twist the stick to tighten the band. Twist it until the bleeding stops. Tie the stick in position Record what time you applied the tourniquet and once it's on, DO NOT remove it. Femur Fractures The femur is the long bone between your hip and knee. Alongside your femur, lies the femoral artery. The femoral is one of the largest arteries in your body and cutting it can result in bleeding to death very rapidly. For this reason, proper attention to femur fractures is extremely important. Fortunately, the femur is a serious chunk of bone so it takes a lot of force to fracture it. If you suspect that the jumper has a femur fracture, you must not let them attempt to walk on it! After the thigh is injured, the muscles will spasm. If the femur isn't there to support the muscle, the sharp bone ends can cut muscle tissue, nerves, and the femoral artery. The way to prevent this is to apply traction in the long axis of the bone. The easiest method of applying traction is to use a traction splint. (The Kendrick traction splint™ is a very BASE friendly item to have. It costs about $100 and folds into a pouch that will fit inside a hip pouch or cargo pocket. If you were sitting there with a femur fracture I could offer you one for a couple thousand dollars and you'd accept.) To apply traction, pull straight on the ankle. Imagine trying to stretch the leg and make it longer. You will need to keep constant traction until an actual traction splint is available. It is very important that you never let up the tension or else serious damage may result. If the shoe comes off, the resulting rebound will be excruciating and bad things will happen. For this reason, remove the shoe on the broken leg. The jumper won't be walking anyway. Splinting Splinting is not really a science. When a bone breaks, the ends are usually very sharp. When these sharp edges move around, you can damage muscle tissue, nerves, and blood vessels. In order to prevent this, you splint the affected bone to immobilize it. Sometimes, you use whatever is available. There are two classifications of fractures, closed fractures and open fractures. Closed fractures include any fracture where the bone does not break the skin. In such instances, proper treatment includes immobilizing the fracture and seeking medical attention. Open fractures occur when a bone breaks through the skin. Signs of a fracture include: A bone end sticking out of the body, A grinding feeling at the site of the suspected fracture, Deformity of the limb, Loss of ability to move the limb, Loss of pulse or sensation, Muscle spasms. Your first step in treating a possible fracture is to stop and take a deep breath. Few fractures are life threatening unless they are mishandled. If there's no apparent life threatening injury, the best approach is a slow methodical one. Cut away clothing from the area and control any bleeding. If you find an open fracture, treat it like any other wound. Generally, you don't want to attempt to straighten out a broken limb. Don't try to realign the bones yourself. There are exceptions to this. If the limb has no pulse or is losing color, you may need to reduce the angle of the fracture to restore circulation. If you need to transport the jumper over rough terrain, a limb sticking out to the side will make things difficult. In these situations, not splinting would be more dangerous. IF YOU DECIDE TO ADJUST A FRACTURE, keep in mind that the sharp end can do major damage to the surrounding tissues so limit movement as much as possible. Also, have someone hold the jumpers arms so you don't catch a right hook. The goal in splinting is to immobilize the bone that is broken. You should try to immobilize the joint above and below the fracture. Find something to use as a splint. Most sites where we jump are in wooded areas so there is usually a variety of sticks and branches to choose from. If possible, pad the splinting materials with a towel or shirt to take up the space between the limb and the splint. This will also improve the comfort of the jumper. Use your imagination and you can usually come up with a splint for most fractures. Forearms can be fractured when you try to catch yourself during a less-than-graceful landing. Fractured forearms should be splinted with a natural curl of the fingers. Place a roll of gauze, or something similar in the palm of the hand. This will go a long way to improve comfort. If you suspect fractured ribs, you can pad the chest and gently wrap it. Placing the arm on the affected side into a sling helps. Try so calm the jumper and have them sit down until help arrives. Limit movement since a fractured rib can puncture a lung. If you suspect a skull fracture, DO NOT place pressure on the head. Monitor level of consciousness and do not give morphine! Joint injuries Damaging joints is a constant threat to BASE jumpers. Ankles are the most frequently injured joints skydiving, BASE jumping, and most sports. There's a saying that goes, "An ounce of prevention is worth a pound of cure." This applies to us because it is pretty easy to reduce the number of ankle injuries. Wearing an ankle brace is an easy and effective measure to prevent hurting your ankles in a sketchy landing. They're available at any sporting goods store. A simple low-grade sprain can keep you grounded for a weekend. A serious sprain can keep you from jumping for a year or longer. If you break a bone, it will usually heal stronger than it was before you fractured it. Ligaments, tendons, and other soft tissues may never completely recover from injuries. Ask anyone who's been jumping for a few years. If a jumper injures a joint in the field to the point that it will not bear bodyweight, you should treat it as a fracture until an x-ray can prove otherwise. Splint it and proceed to the nearest hospital for evaluation. All Sprains can be treated with the acronym, R.I.C.E. Rest: stay off the affected joint and give it time to heal. Ice: apply ice, cold packs or frozen vegetables to the joint. Peas work well because they will conform to the shape of the joint. Just don't eat them after several freeze/thaw cycles. Compress: wrap the joint firmly but not too tight. An ACE wrap can is ideal. If your fingers or toes turn purple, it's too tight. If you squeeze your nail-beds, the color should return immediately. If not, re-wrap more loosely. Elevate: Kick back and have a cold one. Try to keep the injured joint at about heart level. This regimen can be supplemented by taking Motrin (ibuprofen) or Aleve (naprosyn). Follow dosing directions on the package. Both are anti-inflammatories and will help with the pain. If this treatment isn't working, it might be a good time to see a doctor. Summary This paper is by no means, a complete set of first aid information for the BASE jumper. In addition to reading this paper, I highly recommend enrolling in a CPR class, a basic first aid course, and an EMT Basic course. Most junior colleges offer an EMT course and CPR is usually included. These classes will show you how to approach an injury and decide on the most appropriate course of action. First aid is a skill-set we hope to never need. The harsh reality of our sport is that there will be more injuries, and there will be more fatalities. Hopefully someday BASE jumpers will stop being injured and killed. Until that day comes, we all need to know what to do when accidents happen. ---Dexterbase
My First BASE Rig
admin posted an article in DisciplinesFor BASE jumping information, BASE jumping articles, photos, videos and discussions visit BASEjumper.com This article was written entirely by Tom Aiello, BASE 579. Tom has made more than 500 BASE jumps in the past 3 years, from over 100 objects. He is not an authority or expert of any kind on BASE jumping or any other type of parachuting, so all his advice should be taken with a grain of salt. All opinions are those of the author only. By making any fixed object parachute jump, you are taking your life in your own hands, and accepting responsibility for any possible outcome. Copyright 2002. Permission to reproduce and distribute in this exact form only is hereby granted. So, the time has come to buy your first BASE rig. You've made the skydives, practiced your canopy control, and have an experienced mentor to keep you out of trouble. But what rig should you buy? If you have less than 30 jumps, here are my recommendations (more jumps than that, and you're on your own). The really critical thing is to buy purpose-built BASE gear. Lots of people have been BASE jumping with converted skydiving gear for a long time. It is time for this to stop. Skydiving gear is very dangerous for BASE jumping, and has caused, and continues to cause, fatalities, especially among beginners, in the BASE world. Please don't become a statistic. The guiding principle for selecting a first BASE rig is "Keep it Simple." If you are faced with a choice between a simpler and a more complex option, always choose the simpler one. In this article, I will focus on stock (non-custom) gear from major manufacturers, which is what the majority of first BASE gear purchasers must choose from. Note that I will pick and choose from various manufacturers. If you want to take advantage of the "package" prices offered by most manufacturers, you will not have this option. If you are doing this, I strongly recommend selecting your canopy first, and letting that choice determine your package. In the end, it is the canopy that will make or break your system. The container is, in the words of one BASE jumper, "just the garage you park your Ferrari in." CanopyNot Optional: Tailgate It is absolutely mandatory that any BASE canopy deployed with the slider removed or tied down use a tailgate. The tailgate is reefing device developed by Basic Research to promote nose first inflation, and reduce the incidence of line over malfunctions. Under no circumstances should a beginner jump a canopy without a tailgate. Option: Secondary Inlets Several BASE canopies (FOX Vtec, Flick Vtec, Blackjack, Troll) are now available with secondary (bottom skin) inlets. These additional inlets provide faster inflation, give rear riser response earlier in the inflation sequence, and can help keep the canopy inflated in some emergency situations (such as an object strike pinching off the nose). They slightly increase pack volume, especially on the canopies (Troll, Blackjack) where they are covered with one way valves to retain the canopies original flight characteristics. They may also create some poorly understood, but relatively undesirable phenomenon, such as opening backsurge in deep brakes. There is no real consensus in the BASE world on the suitability of secondary inlets for beginners. I believe that beginners should avoid canopies with bottom skin inlets. There are several reasons for this. First, no beginner should jump a system that has poorly understood effects of any kind. Second, a beginner should not be jumping objects in which the advantages of secondary inlets are critical (for example, opening very near to an object). Third, secondary inlets add expense to the canopy (especially the one-way valve systems, which are generally superior to the open vents). My recommendation is to avoid bottom skin inlets until you know enough to want them for your particular (advanced) jumping style. Option: Multi Bridle Attachment The multiple bridle attachment is available on FOX canopies from Basic Research. Essentially, the multi replaces the standard, single bridle attachment point with a line cascading to four separate attachment points (one in the standard location, one near the rear of the center cell, and one each on cells three and five). The objective is to reduce center cell stripping (the center cell pulling out of the free packed canopy on deployment), and thereby improve opening heading and consistency. While the theory is sound, I am not convinced of the practical benefits, especially at subterminal airspeeds. Given that, I would not recommend the system for a beginner, as it adds both complexity and price (US$150) to the parachute system. Option: ZP/Composite Topskin Most BASE manufacturers offer topskins made either wholly or partly of zero porosity material. There are several advantages to this configuration, including better flight performance, stronger flare, and faster openings. Unfortunately, there is one big disadvantage-packing. When you are learning to pack for BASE, there are enough difficulties and distractions without throwing in another one. I'd recommend that a beginner get an all F-111 canopy, for simplicity and ease of packing, which translates into better opening heading. Recommendation: Ace, all F-111, Consolidated Rigging My favorite all around BASE canopy is the Ace, from Consolidated Rigging. The Ace airfoil (which is identical to the Blackjack) has tremendous control range, giving both very high and very low speeds. It flares quite well, although you may have to adjust toggle settings for your personal arm length and preference. It also opens (the real issue in BASE canopies) faster, cleaner, and more consistently than any other unvented canopy on the market. In my opinion, the best canopy for a beginning BASE jumper is a standard, all F-111 Ace.Avoid: Any Skydiving Canopy, Unvented Troll Do not jump any skydiving canopy (PD 7 Cell, Raven, PD Reserve, etc) in the BASE environment. This is an archaic practice that should be stopped. With real, purpose built BASE canopies available, there is virtually no reason to ever leave a fixed object with a skydiving canopy on your back (and the few reasons that do exist-salt water landings, gear confiscation-are pretty much inapplicable to a beginner). Don't kill yourself trying to save a few dollars. Buy real BASE gear. I personally have had very bad openings on my Troll (Atair Aerodynamics). My openings have been wildly inconsistent, and included unacceptable snivels, end cell closures, and asymmetric inflation (leading to off-heading openings). As a relatively experienced jumper, using every technique I can think of, including those recommended by the manufacturer, I have been unable to achieve consistently good openings in my jumps (just under 100) on this canopy. Although the Troll's flight characteristics are fantastic, the openings make this canopy unacceptable for a beginner. ContainerVelcro or Pin? The first thing you have to decide is if you want a Velcro or pin closed container. For a first container, get Velcro. Velcro rigs are simpler, cleaner, and easier to pack and use. Pin rigs are advanced gear, because you must have your pack job dialed in to achieve the correct pin tension, because many acquire adjustment for various altitudes, and because it's harder to close a pin rig without disrupting your pack job. The only case in which you should consider a pin rig for your first rig is if you are an experienced wingsuit pilot determined to jump right into wingsuit BASE. Velcro rigs are unsuitable (and very dangerous) for wingsuit flights. However, Velcro rigs are well proven for delays from 0-15 seconds, so any non-wingsuit jumper should definitely start with a Velcro closed BASE rig, regardless of their intended objects and delays. Option: Alpine Basic Research offers a built in climbing harness as an option on their BASE rigs. I have owned a rig with this option for some time, and have found that I rarely use it. For the extra cost and complexity (the extra buckles have some small potential to confuse the uninitiated), I'd definitely skip this option. Option: Saddle Bags Saddle bags are built in "pockets" sewn onto the leg straps of the rig's harness. These can be handy for stashing bits of rescue, first aid, or climbing gear, or just as a place to put your camera after shooting exit shots of your friends. I also have this option on one of my rigs, and while I do use it, I haven't found it indispensable enough to recommend it. For a first rig, avoid the saddle bags. Option: B-12's B-12's are the snap closures on old-style skydiving leg straps. They can be extremely useful on some relatively advanced jumps (those where room to gear up is limited). However, the use of B-12's with a hand held pilot chute (which is the proper beginner deployment technique) has caused at least one BASE fatality. If you do use B-12's on your BASE rig, be sure that you always snap your leg straps before removing your pilot chute from the bottom of container (BOC) pouch. In the interests of simplicity, this is another option I'd leave off a first BASE rig. Option: Stainless Steel Hardware Following the popularity of stainless hardware in the skydiving world, most BASE gear manufacturers now offer rigs with stainless hardware, both in the harness geometry and the three ring system. Unless you know that you will be making a large number of water landings, there is very little reason to add the expense of stainless hardware to your rig. Option: Sorcerer The Sorcerer is a two parachute BASE container manufactured by Vertigo BASE outfitters of Moab, Utah. Although some skydivers will like the extra confidence of a second canopy, the truth is that the Sorcerer is really an advanced trick rig. Advancing technology has made BASE gear so reliable (statistically more reliable than skydiving reserves), that adding a second canopy really gives very little additional insurance. In addition, the two canopy system is a poor choice for beginners because (a) it makes them less likely to pay the proper level of attention (meticulous) to their pack job, (b) it may make them overconfident, even in situations where the Sorcerer's second canopy (which deploys admirably quickly, in less than 150' under ideal conditions) will have insufficient altitude to inflate, (c) the system is more complex, and a beginner should use the simplest system possible, (d) it is cumbersome to carry around a second canopy you never use, and (e) The extra bulk of large canopies tends to make most Sorcerer jumpers use canopies that are significantly undersized for BASE landing areas, which could be a very costly and injurious problem for a beginner. Note that some skydivers may feel that having a "reserve" is worth the cost. However, the second canopy on a Sorcerer is no more a "reserve" than the first. Any BASE system, properly assembled, maintained, and packed, will open more reliably and consistently than any skydiving reserve system. Jumping a Sorcerer isn't like having a reserve-it's like having two reserves. Save the Sorcerer for advanced trick jumps (like BASE fun-aways), when you are more experienced. For now, stick with a standard BASE system. Option: Para-pack The Para-pack is specialized BASE rig that allows you to stow gear (camping gear for long approaches, for example) between the back pad and the pack tray. The rig is remarkably clean, and maintains tension over the pack tray quite well. However, unless you have a specific need for this type of expedition jumping, there is no need to spend the extra money (it's something like US$500) and deal with the extra complexity of the system. Option: Hook Knife Originally, a hook knife was considered mandatory equipment for BASE. However, as gear technology advanced, and it became clear that the incidence of slider up line over malfunctions was extremely low, hook knives started to be left off of BASE rigs. However, there have been at least three documented cases of slider up line overs in the past two years, and one of them required the use of a hook knife to clear. Even if this happens on only one in 1000 jumps, it is worth carrying a hook knife for the other 999. Since the cost of a hook knife is quite low, and there is no inconvenience in carrying one, you should purchase a hook knife with your first BASE rig. Recommendation: Vision, Gravity Sports Limited My personal favorite Velcro rig is the Vision, from Gravity Sports Limited. The Vision was designed, built, re-designed, and re-built by Dennis McGlynn while he was jumping very aggressively. Everything about this rig screams "ease of use." It is incredibly simple, it is very comfortable, and it absolutely minimizes distortion of your pack job, both on the way into, and on the way out of, the pack tray. Secondary Recommendation (Pin): Gargoyle, Morpheus Technologies If, and only if, you are an experienced wingsuit pilot intending to take your wingsuit to the cliffs as soon as possible, you should skip a Velcro rig (very dangerous for wingsuit jumps due to the potential for a premature deployment) and go straight to a pin rig. It would be far better to buy a Velcro rig and become an expert BASE jumper before launching your wingsuit. However, if you are dead set on moving straight to wingsuit flights (which I do not recommend), you will need a pin rig. My favorite pin rig is the Gargoyle, by Morpheus Technologies. If you are jumping a wingsuit, you will definitely want the dynamic (open) corners option. The Gargoyle has superb pin protection (better than any other two pin rig), does an excellent job of maintaining pack symmetry both into and out of the pack tray (it is probably the best of the pin rigs in this critical area), and can be closed exactly the same at any altitude (reducing complexities that could be troublesome early in your BASE career). Avoid: "Home Made"Rigs Many jumpers (including myself) begin their BASE careers using "home-" or "rigger-made" BASE gear. Unfortunately, many of the minor manufacturers who produce these rigs are so far out of the main stream that they make rigs with design flaws (minor or major) that have long since been worked through and eliminated from the rigs built by major manufacturers. Avoid purchasing a rig from a friend, or your DZ rigger, and instead purchase your gear from a major manufacturer. In general, if you cannot buy a real, purpose built, BASE canopy (Ace, Blackjack, Mojo, FOX, Flick, Dagger or Troll) with your rig, from the same shop, you should look to purchase the container elsewhere. Avoid: Unstiffened Side Velcro Some older Velcro rigs have unstiffened side flap Velcro. Examples include early Odysseys and Reactor 3's. Unstiffened side flap Velcro can shrivel with the shrivel flap during a head down deployment, and should be retrofitted with a stiffener to prevent a pilot chute in tow malfunction. All major manufacturers have rectified this design flaw, and will retrofit older rigs to eliminate the problem. Pilot ChutesEventually, every BASE jumper accumulates a large collection of pilot chutes for various delays. As a beginner, you will need to acquire at least three. To paraphrase my BASE mentor, you will need one PC each for terminal jumps, really low jumps, and everything else. In general, that means one 32-36" PC (terminal), one 46-50" ZP PC (low) and one 42" ZP PC (everything else). Unless you live in Norway or Australia, you will quickly find that the 42" ZP is your workhorse PC, and that you leave it on your rig for everything from 2-6 second delays. Later on, you will want to fine tune your PC's for your delays. For example, one manufacturer recommends a set of four PC's (32", 38", 42", and 46") to cover all possible delays. When you are starting, though, you can save money (and simplify your systems) by going with just three-little for terminal, big for go and throws, and 42" for everything else. Just about everyone uses ZP material exclusively for BASE PC's. In some cases, F-111 can have advantages over ZP, but all your subterminal PC's ought to be ZP in the beginning. Option: Bridle Attachment Point There are several different configurations possible for bridle attachment on a pilot chute. The standard configuration used by virtually every BASE gear manufacturer (CR, BR, Morpheus) allows the jumper to asymmetrically attach the PC to the bridle. The older style of attachment (Paratech Rigging) is far superior, as it makes an asymmetric attachment (which greatly contributes to orbiting, and hence degrades heading performance on opening) virtually impossible. If at all possible, order your PC's with the older "loop" style attachment point. Option: Apex Vents Some manufacturers are now offering pilot chutes with mesh vents at the apex. The purpose of these vents is to dampen the oscillation inherent in a pulled down apex round (like a pilot chute), as well as reducing the orbiting that often results from a vigorous PC toss. This is one of the few options that I would strongly recommend for any jumper, even a beginner. The vents really don't create any added complexity packing, and really do help improve opening heading (which suffers dramatically from oscillating and orbiting pilot chutes). Vented pilot chutes are not recommended for low freefalls with very short (less than one second) delays, as they do inflate slightly slower than unvented PC's. Recommendation: Apex Vented 42", Consolidated Rigging My favorite 42" PC is the A-V pilot chute from Consolidated Rigging. The CR A-V series, in addition to the apex vent, has a slightly oversized topskin, which contributes to stability. Recommendation: 36" F-111, Basic Research For terminal delays (without a wingsuit-wingsuit PC's should be slightly larger), the standard BASE PC is either a 32" ZP, or a 36" F-111 PC. For a beginner, I would recommend a 36" F-111 PC, as F-111 PC's appear to be more stable than ZP (even vented) PC's, and the advantages of ZP (faster inflation) should not matter to a beginner at terminal (no beginner should pull low enough that the PC inflation time difference becomes important). Recommendation: 48" ZP, Basic Research For low, hand held deployments, I prefer the Basic Research 48" ZP PC. BR does not put a handle of any kind on their 48", which is mandatory for hand held deployment. Further, they do not put any kind of cap or vent on the PC, either of which could slow inflation, and cost critical feet at low altitudes. Avoid: The Hook, Gravity Sports Limited Gravity Sports pilot chutes have the load tapes applied on the block, rather than the bias of the ZP material. This allows the pilot chute to stretch and deform, both over time with wear, and instantaneously during each deployment. This can result in asymmetries and oscillation, both of which can degrade opening heading. RisersAlthough almost all BASE specific risers meet certain criteria (type VIII, LRT style toggles, etc), and you should be fine sticking with whatever riser and toggle system comes standard with your first rig, it is slightly better to purchase toggles and risers separately, to allow a wider choice in available options. If cost is a primary consideration, just go with the standard setup. But if you have a bit more money to spend, consider ordering exactly the riser setup you want. Not an Option: Mini-Risers (Type 17) Occasionally, skydivers (and one German BASE manufacturer) will attempt to use mini-risers on a BASE rig. This is totally unacceptable. Mini risers have failed in actual use, and if that were to happen on a BASE jump (more likely than on a skydive, as BASE openings are harder), you would be lucky to survive. Under no circumstances should a beginner (or any other BASE jumper) use equipment with mini-risers. Option: Pin v. Cloth Toggle Stubs BASE toggles are available with either standard (stiffened cloth) or metal pin toggle stubs. The standard stubs are generally preferred. Although the metal pins have virtually no chance of toggle hang-up, the incidence of hang-ups on the cloth stubs (with the thick Dacron lines used for BASE canopies) is near zero. Also, the metal pins tend to wear the brake settings more quickly, and are slightly more likely to prematurely release ("blow" a toggle) during the opening sequence. Option: Mini Rings (RW8) Most BASE gear manufacturers offer mini three rings, either as an option, or standard equipment. Since the manufacturing tolerances for these rings are tighter, and there is no disadvantage in using standard large (RW1) rings, avoid mini-rings on your first BASE rig. If possible, you might wish to use large tandem strength (RW10) rings, which are available from some manufacturers. Option: Big Grab Toggles Several manufacturers now offer stiffened toggles. These go by a variety of names, including "Big Grab" and "EZ Grab". Although the best way to avoid object strike is to correct heading on risers, there are some situations in which a BASE jumper wishes to release the toggles immediately, with no hesitation and no fumbling. Stiffened toggles are designed to make this much easier, and generally work in that regard. They do make packing marginally more difficult, and for that reason, should be avoided by a beginner. However, like line release toggles, this is a piece of equipment you should consider adding quite early in your BASE career. If cost is a major issue (you don't want to spend the extra money on a second set of toggles), it is possible, but not recommended to start with big grab toggles. Option: Integrity Three Rings BASE risers are now available in both standard three ring and reversed (integrity) configurations. Most BASE jumpers consider the reversed (integrity) three ring to be standard equipment for BASE. Integrity risers are marginally stronger than standard risers, but are also a bit more difficult to manufacture properly. Since a standard type VIII riser has never failed in actual use, either riser set up should be fine for a beginner. The standard set-up (with a grommet through the riser) is probably more familiar to a beginner, and is definitely more field tested (there have been two reported incidences of unintentional riser release on BASE jumps-although the cause is undetermined in both instances, both releases occurred on integrity style risers). On balance, the standard three rings are probably a slightly better option for a beginner. Option: Line Release Toggles Several BASE manufacturers now offer toggles that can release the control line, allowing a jumper to clear a line over malfunction without resorting to a hook knife. These line release toggles are the best currently available line over clearance technology. However, the extremely low occurrence of line over malfunctions in the BASE environment, combined with the added complexity of the line release toggles, indicate that beginners should avoid their use. Although they may become standard equipment for BASE, they are not yet sufficiently proven to recommend their use to a beginner. As an aside, in the event that you do choose to purchase line release toggles with your system, I would strongly recommend a toggle with a one handed operation (such as Vertigo BASE Outfitters' WLO [What Line Over?]), rather than a toggle with a two handed operation (such as the Gravity Sports Supertoggle. All things considered, though, a beginner should avoid adding this extra complexity to their system until they are comfortable with their basic equipment. Recommendation: Standard Three Rings, Standard Toggle, Morpheus Technologies My favorite standard riser is the one manufactured by Morpheus Technologies. Essentially the same as the risers made by BR or CR, Morpheus' standard riser is a non-integrity three ring, with the LRT toggle system, and RW10 (tandem) three rings. Stash BagOption: Waist Band Some manufacturers (Vertigo BASE Outfitters, Gravity Sports Ltd) offer stash bags with waist bands, either permanent or removable. For technically difficult approaches, or just for longish hikes, these waist bands are an absolute life saver. Since they are generally removable, and add negligible bulk, they are highly recommended for all jumpers. Option: Waterproof Material Some manufacturers offer stash bags made of waterproof material. Whether you decide to use one will depend on your jumping environment. If you live somewhere that it rains often, you will find the water protection well worth the investment. However, if you live in a dry area, or frequently need to wad up and pocket your bag quickly, you may find that the extra bulk of the waterproof fabric makes it more trouble (and cost) than it is worth. I know that my waterproof stash bag (Gravity Sports, Ltd) more than paid for itself the first time I had to swim across a creek to reach the trail and hike back to the car (my rig stayed completely dry on my back). Option: Cliff Pack You may want to consider adding a heavier cliff pack to your gear collection. A cliff pack is a backpack, sized to fit your rig, protective gear and a bit more, with a decent suspension for hiking, and which can be collapsed into a waist pack for jumping. Although most modern jumps do not require this gear, there are certain areas with long hikes (Norway comes immediately to mind) where a cliff pack will significantly improve your hiking experience. Although you probably won't need one initially, if you are planning a trip to a site with long hiking approaches, definitely consider purchasing a cliff pack. Recommendation: Heavy Duty Stash bag, Gravity Sports Limited My favorite stash bag is Gravity Sports' heavy duty stash bag. This bag is burly, will take tons of abuse, has no plastic buckles (which can break at inopportune moments), and compresses moderately well. If you have a chance to pick one of these bags up, grab it. Avoid: Stash bag, Paratech Rigging I had very bad luck with my Paratech stash bag. The fabric was too light, and the bag survived very few jumps. In addition, the cord lock that closed the bag kept sliding open, so I had to stop every few hundred yards to verify that my gear was still in the bag. NOTE: My recommendations have evolved considerably during the course of this writing. Although the basic equipment I recommend for a beginner (Ace in a Vision) is the same, my views have changed as to several options (Big Grab Toggles, WLO toggles, Integrity Risers) for this writing.

Getting Into BASE
admin posted an article in DisciplinesFor BASE jumping information, BASE jumping articles, photos, videos and discussions visit BASEjumper.com This article was written entirely by Tom Aiello, BASE 579. Tom has made over 500 BASE jumps in the past 30 months, from more than 100 objects. He is not an authority or expert of any kind on BASE jumping or any other type of parachuting, so all his advice should be taken with a grain of salt. Copyright 2002. Permission to reproduce and distribute in this exact form only is hereby granted. Virtually every time I tell someone that I'm a BASE jumper, their first question is "how could I get into that?" After answering that question dozens of times, I decided to write it all down, so that I can avoid repetition induced laryngitis. There are as many different ways of getting started BASE jumping as there are jumpers. But, after some soul-searching, some discussion with friends, and some internet research, I've decided that the course I wish I had followed, and the one I've tried to set people on, goes something like this. Check the Fit BASE jumping is not for everyone. Give yourself a long hard, look, and decide if BASE really fits you. It's virtually impossible to objectively evaluate yourself, so it might be helpful to have a (close and tactful) friend help you with this step. Does BASE jumping fit your physical abilities? BASE is not really about personal fitness (although it helps) or athleticism (which only comes into play in advanced sub-disciplines). In BASE, the important physical abilities are reaction time, coordination and balance. Evaluate yours. It may be helpful to ask some of the following questions: If you are sitting at a desk, and knock a pencil off, do you pick it up off the ground, or did you catch it in mid-air? When you spill a bottle of beer, do you have to get up and get a new one, or do you right it before you've lost most of it? How often do you trip or stumble? Does BASE jumping fit your mindset? The best BASE jumpers are organized to the point of anal retentive. They also have an intellectual curiosity about almost everything. Have you ever wondered how the reserve system on a skydiving rig works? How many times did you trust your life to it before you starting wondering? Are you always trying to find a pull-up cord to close, or do other people ask you for them? Do you make correct decisions in pressure situations? BASE jumpers need to react quickly, and correctly, in life threatening situations. Have you ever been confronted with an oncoming car in your lane? How did you react? Did you have to think about it, or did it just happen for you? BASE will best fit a person who is intellectually curious, has good reactions, responds quickly and correctly (without having to think during the emergency), has excellent coordination and is highly organized and detail oriented. You can definitely still be a BASE jumper who has trouble with one or two of these things, but if you are weak in most of these areas, BASE is not a good sport to take up. Make the Decision Make absolutely certain BASE is really what you want. This sport is dangerous, sometimes illegal and very addictive. It will take over your life. I would never advise someone to get into it (and I have found it to be the most rewarding experience of my life). In my short time in this sport I've seen two life flight helicopters from the outside, two more from the inside, the back of a police car, several broken bones and a funeral. I've also spent three weeks in Intensive Care and 18 hours in neurosurgery. Are you sure you really want to do this? There are lots of different reasons to get into BASE, and I have given up trying to decide which are the "right" ones. The important thing is that your reasons are important enough to you to outweigh the potentially enormous costs of BASE jumping. Unless you are a NASCAR driver, BASE is by far the most dangerous thing you will ever do. Statistically, you have something like a 5% chance of dying by the end of your BASE career. Worse, your chance of serious injury (think hospital time) is more like 95%. I know three BASE jumpers with more than 500 jumps who have not spent serious time (more than a day or two) in the hospital due to BASE accidents. Even they agree that it is just a matter of time until they are seriously injured. If you are not ready to die BASE jumping, you are not ready to BASE jump. Go to this web site: http://juliabell.home.att.net . Read the entire thing. Seriously. Still want to be a BASE jumper? Then read on... Do Your Homework Next you need to find out everything that you can about BASE jumping. Talk to every BASE jumper you can. Read every article you can find about BASE, rigging or weather. Get on the internet and find everything you can about BASE (there is a whole lot more than you'd think). I have included several of my favorite references at the end of this article, but there are many, many more. Get Your Head Straight Now that you've made the decision to jump, make sure that you have the right mentality. There are two important pieces of that mentality that will keep you alive in this sport. Never do anything that doesn't feel right to you. If you're not ready for something, don't do it. We all determine our own learning speeds, and there is no way to know in advance what you'll be comfortable with. Don't be pushed into doing things you're not ready for by overeager partners or teachers. Never be afraid to back down. It takes far more courage to back off the exit point than to jump. There are definitely times when it is right to back off, and knowing when to heed that little voice in your head is critical to your survival. This sport is very, very serious, and taking it lightly will hurt, maim, or kill you in short order. The rest of your mentality you'll develop as you go, learning from other jumpers, from experience (both positive and negative) and from the rest of your life. Tell Your Family It is the responsibility of every BASE jumper to tell their family that they are involved in BASE, that they understand the risks, and that they have chosen to take those risks. Sit down with your family and talk to them about BASE. This is obviously an extremely difficult proposition. Facing your family with your decision to engage in a life-threatening activity cannot be easy. However this discussion is important both for you and for the sport of BASE jumping. An honest, open discussion with your loved ones will make them feel more included in your decisions. They will generally be more impressed with the maturity and thought that has gone into your decision to jump. This can help avoid the arguments, tantrums, and guilt trips that might otherwise be thrown at you by family and friends who don't understand your activities. An explanation, by you, that you understand and accept the risks involved, will help prevent your family from attacking other members of the BASE community in the event of your injury or death. There have been far too many cases of the families of dead jumpers accusing, confronting, suing and even prosecuting other jumpers as a result of fatalities. Don't let this happen to your friends. Write a letter to your friends and family, to be opened in the event that you die BASE jumping. In the letter, explain why you have chosen to take up BASE, what you hope to get from BASE jumping, and why you are willing to risk death for it. Give sealed copies to (at the very least) your family and your BASE mentor. Do this to defuse any conflicts that might arise from your death. Make the Skydives First, make at least 200 skydives. You need to make these skydives in order to practice accuracy, tracking and canopy control skills. You also need to establish a general comfort level with parachutes, free fall, and split second decisions. The skydivers who are best prepared for BASE generally jump large, 7 cell, F-111 canopies, have had a number of malfunctions and responded correctly, and are comfortable with multiple skydiving disciplines. If your only focus is BASE jumping, don't succumb to the temptation to become canopy swooping freeflyer. Instead, focus on CRW and Accuracy as your skydiving disciplines. To practice tracking make entire skydives in max track. Don't count on the limited tracking on break off, or on the balanced tracking of a tracking jump. Make the whole dive tracking as hard as you can, with camera and coaching if possible, and work on getting the most lift, and the most drive out of your track. For accuracy practice, it's best to use the canopy that you intend to BASE jump with. Try to set up low (under 500 feet), to simulate the BASE environment. Don't forget to make approaches cross- and down-wind as well, since you will often have to do this while BASE jumping. For canopy practice, you should make some CRW jumps (on a CRW canopy) and then do some canopy drills on your intended BASE canopy. CRW is a great way to learn canopy flight characteristics in tight spaces before you get into the BASE environment (and CRW with your BASE canopy is an excellent drill-after you've learned some CRW skills). Be sure you've made several night jumps during your skydiving career. In many places, BASE jumps are made almost exclusively at night (to avoid arrest, incarceration, and gear confiscation), and comfort with flying and landing your canopy at night is essential to survive these jumps. Make some jumps on your BASE canopy to learn its performance envelope. Pay particular attention to riser input, practicing riser turns and riser flares. Make sure you practice your riser turns before popping your toggles-that's the way you'll have to do it to avoid smacking the side of a cliff one day. Obviously, you'll want to practice them after grabbing the toggles, as well. Find a Mentor While you are learning to skydive, you will doubtless meet skydivers at the drop zone. Try to find and meet the local BASE jumpers as well. Your goal should be to find someone with 200 or more BASE jumps, who you think will be a good teacher, and whom you get along with. You also have to trust them with your life (that is what you will be doing, after all). Get a BASE Rig Now, with proper canopy skills and an instructor, you need to find a BASE rig. Your best bet is to buy a new, Velcro closed, BASE specific rig from a major manufacturer, and put a real BASE canopy in it. You can also find good used gear (check the classified ads on the BASE board: www.blincmagazine.com). The key is to get actual BASE specific gear. Lots of people will try to sell you converted skydiving gear (Ravens, Cruiselites, Pegasus's, etc). Avoid this and get real BASE gear. Everyone has different preferences in gear, but the key is to find actual, purpose built, BASE gear. Take a First Jump Course So, now you have the pre-requisite skydiving skills, an appropriate rig, and you've found an instructor. Time to go jumping, right? Wrong. Now it's time to get to work. Before you can make your first jump, you still have to learn basic rigging and packing, dead air exits skills, and simple ethics. There are two ways to do this. The simplest is to cough up US$1000 or so, and take a first jump course from one of the major gear manufacturers. Since most of us don't have an extra grand to throw around, we tend to try to skip this step. I don't recommend this. It really is worth the money to get qualified, professional instruction. You wouldn't try to make your first skydive without paying for instruction, would you? Even if you had a friend who swore he "knew all about it", and could easily "take you for a jump." First jump courses are also available from various BASE organizations around the world, such as the Australian BASE Association (which maintains a database of qualified instructors in Australia) and the Norwegian BASE Association (which has classes available at Lysefjord in an attempt to minimize accidents at that popular site). If you have the money, though, my preference would be to take your course from an American manufacturer, as their "teaching object" (a 486' bridge over water, with a huge grassy landing area) is generally the safest for a first time jumper. There is a similar object in Southern Europe, and Robert Pecnik offers a First Jump Course there. Lots of people try to save some money by getting their friends to "teach" them. This is a bad idea for several reasons. First, you don't know that your friend really has the qualifications to teach. Second, you don't know that he's really motivated to do a thorough job teaching. Sure, he can get you off for that first jump, but what did he teach you about dealing with your unstable launch on jump number 12? Third, you will learn more if your First Jump Course is not taught by the same mentor who guides you through your next 20-50 jumps. Finally, these "informal" first jump courses can drag on for weeks, months, even years. If you contract with a real business, you know the exact dates of your course, and you can plan for it. Watch Some Video Now that you have an idea of what a BASE jump ought to look like, get your hands on some BASE video. The best video for this is the "Lemmings Exits" series from Bridge Day (http://www.lemmingsvideo.com/). Try to get several years of "Lemmings Exits", and whatever other BASE video you can find. Watch the video, preferably with your BASE mentor. Evaluate each jump. The more errors you can see before jumping, the more likely you are to avoid them yourself. Get Started Now you're ready to start jumping. After your First Jump Course, you should have a solid knowledge of gear, rigging and packing, some theoretical knowledge of malfunctions and solutions, and a practical set of launches to work from. The next step is to get home and make as many jumps (in as short a time) as possible with your BASE mentor. Ask as many questions constantly. Try to learn as much as you can. Once you feel comfortable (and so does your mentor), start branching out and jumping with other people. Ask them the same questions (they may have different answers). Watch different people pack. Watch different people jump. Always ask why things are done a certain way. Keep Learning Now that you have 20-30 jumps, and can hang with the local crew, you can consider yourself a solid beginner. There is still a lot more to learn, see and do. Never stop learning. In addition to being a good way to stay alive, it's one of the most rewarding things about the sport.
