Tsynique 0 #1 February 7, 2012 Hello, I am doing a little research and have a question stuck at the back of my head for a while now. I tried googling, reading the forums but nothing came up. I guess such a case is too infrequent (or maybe never even happened, unless maybe to some Lutz). So, my question is about hand deployed pilot chutes. What can possibly happen (good and/or bad) if one would extract the pilot chute, stretch their arm forward as per normal deployment but wouldn't let the PC go for, say, 10 seconds? Since, this is a theoretical research I would even appreciate ideas that have a one in a trillion possibility. Also, I think I know a thing or two about cases when the PC is barely thrown out, just extracted and let go but if someone could elaborate on this as well, it would be nice. Thanks! P.S. No, I haven't tried or plan on trying either of the cases. Quote Share this post Link to post Share on other sites
yoink 321 #2 February 7, 2012 Work through it in your head. You've got 44 jumps, so you understand the components of a parachute system and basically how they work.... What do you think would happen? You pull out your PC to full arm stretch and hold onto it. What do you think is happening to the bridle that is connecting the PC to the pin? It's not sitting quietly in on your back, nor is it streaming cleanly above you - it's rattling around in your burble providing a massive snag hazard! While it's doing that a loop wraps around your foot.... Now what? How would you deal with this situation? Remember, you're at deployment altitude and still in full freefall with a PC in your right hand... Even worse a loop wraps around your foot, you don't notice and you release the PC. Now what? How do you deal with THIS? Even WORSE, you do all of the above, kick your leg to try and disentangle yourself, dislodge the pin holding your container closed but still have the wrap on your leg... You've now got a SERIOUS problem. Think and try to visualise exactly how you would deal with each of these scenarios - it's great practice! Then work like hell to make sure you're never in that situation in the first place. Seriously - this is one of the worst malfunctions I can imagine. If you pull out the PC, throw it authoratively. Do NOT hold onto it. Quote Share this post Link to post Share on other sites
popsjumper 2 #3 February 7, 2012 You said, "extract the pilot chute, stretch their arm forward as per normal deployment..." That is not 'normal deployment' and I'm sure you really didn't mean, "stretch their arm forward. I'm sure you really meant, "stretch their arm straight out to the side. To answer your question directly: Doing that exposes you to a risk of a 'horseshoe' malfunction. As Yoink mentioned...bridle wrapped around a part of your body or around your rig. Or, the PC coming out in front of your arm and pulling the lines and bag out over (in front of) your arm instead of behind it. Not good. For the weak throw ("cases when the PC is barely thrown out, just extracted and let go) you are exposing yourself to both 'pilot chute hesitation' AND 'horseshow' malfunctions. If you are lucky only the PC hesitation occurs and that easy to handle. The PC getting hooked on something on your rig behind you, a horseshoe, is bad. You really should already know these things.My reality and yours are quite different. I think we're all Bozos on this bus.

Since, this is a theoretical research I would even appreciate ideas that have a one in a trillion possibility. The bridle will come out, catch air at a nominal 120 MPH, and vibrate. Since today's skydivers are such wimps the closing loop may be loose enough for the bridle to pull the pin out giving you an open container for 10 seconds. Maybe a toggle starts to catch air and come loose or something else and the flapping parts get caught on your Go Pro as you open. Or maybe the bag is a loose fit in your container since you've down-sized a bunch and it starts to come out. Maybe you can cut-away the malfunction and break your neck due to the go-pro hangup. Maybe you fire your reserve into the trailing mess and die. Oops. Pulling the pilot chute out is like pulling the pin on a grenade without having a firm grip on the handle. Something is likely to explode with bad results for the operator if he hangs on to it. Or maybe nothing happens. Quote Share this post Link to post Share on other sites

He may have been taught "it is critical to throw the PC away as quickly as possible" but not been told what can happen if he does not. Of course. Which would mean he wasn't taught about the consequences of improper technique, which would be very disappointing. It's not enough to know what to do. We also need to know why. Of course he could have just asked an instructor at his home DZ. Sure worked when I was a noob.Chuck Akers D-10855 Houston, TX Quote Share this post Link to post Share on other sites
BillyVance 34 #13 February 8, 2012 I can think of one jump where hesitating to throw my PC possibly prevented a freefall or canopy collision. Quincy, Illinois, Free Fall Convention 1997. I was on a raft dive as a free floater, not holding the rope on exit. I was supposed to fly in and dock. Well the raft floated like a bitch and I couldn't keep up with it and sank out. Somebody else did, and I didn't even notice. He sank a lot faster than I did. I did debate whether to track away or stay in place and pull a bit lower than the others as we all shared our general pull altitudes prior to the jump. I chose the latter. Well, at pull time I grabbed my hacky handle and pulled, and right at the exact same time or a split second later I spied an open canopy directly below and growing larger fast. He shot up no more than 15 feet away and I was still holding my PC handle. I let go as soon as I was clear, and had an uneventful deployment. I kept the handle straight out to the side with my hand pointed up so it was slightly higher than my body. He and I both fucked up though he took no share of the blame when we met afterwards.

It usually does work, but may not work as well in some places. I realized that a lot of what I learned at my first DZ was wrong when I started to go to other DZ's.

riggerrob 558 #17 February 8, 2012 Circa circa 1980, it was fashionable to wave-off with your pilot-chute in your hand. That fashion lasted one week. ... but too many people suffered horseshoe type malfunctions. If you do that with a tandem drogue, you will force your rigger to sew multiple patches on the drogue and it will wear out prematurely. Since the rigger gets paid by the hour, he will be happy, but the DZO will be furious. Secondly, hanging onto the drogue for too long also gives your student more opportunity to flip you inverted .. vastly increasing the risk of drogue entanglement.

obelixtim 100 #18 February 8, 2012 When hand deploy pilot chutes first came out, they were called "throwaways". There was a reason for that.

Decodiver 0 #19 February 8, 2012 Two bits of advice which will serve you well in skydiving. Throw you're PC like your life depends upon it Why? Because your life depends upon it & Track on break-off like your life depends upon it Why? Because your life depends upon it Get the idea? Coops.

fcajump 153 #22 February 8, 2012 First - GLAD you asked!! Keep asking. Second - as you see from the replies the 99.44% pure answer is "don't do that... it can be very bad" There are very rare times when it might be necessary to delay, but that means that there have already been mistakes made and you are willing to take the risk to avoid a bigger problem (like an open canopy just off to the side and below you). This is a high-experience option, not to be taken lightly. Take that video seriously. KEEP ASKING. That is the GREAT thing about this site (and instructors).

Tsynique 0 #23 February 8, 2012 Thanks for all of your answers - those related to my question and others too. Now I know how to continue my research since this is out of the way. As far as my personal experience and training goes, despite learning some more later, during AFF1 training I was told that I would get a horseshoe if I hold the PC too long and I was told how and why to deal with a horseshoe and of course, emphasised that it's bad - really bad. However, I wasn't told exactly why would I get a horseshoe, I wasn't explained the exact mechanics that would cause it (in similar way popsjumper, yoink or others explained here). Those exact details put in the right place and order was what I needed for my research, so thanks again guys. I would have asked someone at my DZ like I always do but it's winter in my hometown, so DZs don't work. Quote Share this post Link to post Share on other sites

However, I wasn't told exactly why would I get a horseshoe, I wasn't explained the exact mechanics that would cause it ...your bridle can/will whip around and might grab just anything. Anything like a video helmet... It is a bad idea to hold your PC, sometimes you take the decision that it still is what you have to do, but you need to know it can bring you bigger problems. If you haven't seen my video, you can check in the incidents forum for a thread called "Last Night a Cypres saved my life", and the link to the video is at the end of the thread.
