emergency exit

Thanks Faulk for the info but I still am not clear on the reasoning behind telling a student to go straight to their silver. Does the reserve normally open quicker or is it just supposed to be easier?? I am still a little unclear on the "why".



One of the key reasons students are told to use the reserve rather than the main when getting out low is that every student rig has an AAD. Using the reserve when close to AAD firing range prevents a two canopy situation.

Speed of opening is another reason, and there are a few more, but they have already been discussed on this thread.

Nice answer Bill. I'd only like to add that we should remember that things change as we get more experience and what we were taught as students may and often times should change (and sometimes not), especially as our equipment changes. Keep current on your procedures and don't stop learning.

2500 feet with the engine still running? I would have launched the formation



Hahahaha! You crazy bastard! I once launched a 2-way from...errr....ummm......uhhh..... 2000'. Yup, the pilot even vouched for it. ;) Well, OK, but we were pretty damn close to getting it. Turned three points before tracking and dumping. Odd that I could have been that stupid back then and still be alive now.

Hmmm... 750ft rings some bells...

oh right... the snivel on my old Spectre :D

Experienced or not... in my ears this sounds ridiculous... he would have saved money if he jumped from a nearby cliff/antenna instead! ;)

(I have seen a very experienced jumper who packs his own reserve bail out at 750 feet in a non emergency situation)
What kind of idiocy is THIS ???!!!!
That VERY EXPERIENCED jumper is irresponsible.
as evidenced by the impression he made on you and probably others. Hate to clue you in, but exiting at that altitude without the assistance of a static line, or instructor assisted deployment
CONSTITUTES an emergency situation, in my book.,
not to mention it sets a very poor example......

I guess it depends on what era you're from and how experienced you are. I know an experienced base jumper who jumped out of a Cessna at 250 feet on his CRW main. I know tons of people who have done h&ps from 900-1300 feet on cloudy days. So much depends on your canopy and your pack job. The pilot doesn't cut - with the right equipment (i.e doing this on an Extreme 60 might not be smart.) If I left a 182 at 1000 feet on my CRW main, I'd have good canopy at 995. It opens a bit fast :-)

I once watched a guy test out his new BASE rig from an Otter at 500 feet. Illegal? Yes. Dangerous? Less so that a tower.

I like to think that I am from all the eras.
And each one, as different and amazing as they are,
all stress.... safety. When most recommendations for
cutting away and getting under a reserve, set a hard deck for that, at above 1000 feet, then I just don't get the logic, in exiting at 50 % or 75% of that altitude... that's all. Hey man when the ceiling was at 1500 feet, we just didn't jump....
One of the great aspects about this amazing sport/recreational activity that we all share, is the wonderful variety of self expression and individuality
which is possible at all times..on and above a Drop Zone.......maybe "idiocy" was to harsh a term (if the alt. was 1250 feet I may have said "crazy" but the 750 ft...pushed me over the edge. hahaha).
I have not yet made a base jump. I would like to.
I am not afraid (I think). 'Cause I also come from an era which stressed, accuracy landing, flying a canopy at slower speeds, and touchdowns within 1 meter of your target,,,,,,,I hear that can come in handy on a BASE jump....but when in a plane, my motto would be "The more altitude the better"!!!!!

Just a point of clarification for people that wouldn't know.

The only thing that would have technically been in violation of the FARs would be that it was a non-TSOed rig with only one (also probably not TSOed) canopy in it.

It most definately would be in violation of the BSRs, but that's not quite the same thing as illegal. ;)






Well, on second thought, you probably could also throw in an FAR 104.5 violation if you really wanted to. :P

A lot of people confuse the word "illegal" for "dangerous" or "bad."

A better synonym for "illegal" would be "unpopular."



Using a BASE rig when jumping from an airplane is illegal. Check FAR 105.43. A skydiver must use an "approved" single harness dual-parachute pack. There is only one single harness dual parachute BASE rig, and it is not approved under the regulation.

Just wondering... Is it any better to "test-jump" gear from 500 ft. than a safer altitude?

No, I think a much better idea would be for people to understand the diffferences between being legal and safe.

Just because something is legal doesn't make it safe.
Just because something is illegal doesn't make it unsafe.

For instance, there is no FAR that prevents a glorly seeking whuffo parent from putting his 10-year-old into a TSOed rig and letting him make his first jump, a solo balloon jump from 500 feet, on a moonless night. This would be, according to the FARs, -completely- legal but I'm guessing -probably- not very safe.



(On second thought, a really pissy FAA inspector probably would throw a 91.13 and 105.4 at the balloon pilot and some whiney-assed social services agent would probably have something to say about child endangerment. Of course, those are -subjective- laws.)

Hehe... I know that you do them with dummies, I was trying to add a bit of humor to the thread. You miss the wink there Chris?

I've seen a lot of photos of some various test programs including the p124 project. I also know they used used a live jumper for some of the later tests of that system.

Ah yes. The reason we all have an altitude below with we go straight to the reserve is
a. The reserve is designed to open faster
b. The reserve is packed by someone specially trained - it should be
somewhat more reliable than a main.
c. They're 7-cells, i.e. typically more docile than our mains - so less likely to have squirrely openings and less likely to mal.
d. Most people pack their mains to open softly (slowly). Reverses are packed to OPEN. I believe 300 feet is what is required to pass the TSO - most open faster than that.
e. A reserve has a freebag - i.e. the bag isn't attached to the parachute. This can help if you open unstable or something there is more of a chance the parachute will open even if part of the system is wrapped around an arm or a leg.
So in an emergency when you need a canopy NOW, your reserve is a more reliable choice. At some altitude for everyone, a bailout would go straight to the reserve for the above safety reasons. You wouldn't have time to implement emergency procedures anyway (again, this altitude varies with the person).



I would think that one more reason to go to the reserve might be because in an emergency situation where you are low, you don't have time to really scope/spot your landing area, so you probably want the most docile canopy above your head.
In some instances, your landing area will not be as ideal as the landing area at the dz, it might be tight with lots of obstacles, possibly a plowed up field with lot's of deep trenches etc. etc. Of course, all this depends on how comfortable/how good of a canopy pilot you are. Personally, I would rather be under my larger, more docile reserve.
On the other hand, you canopy jocks who fly sub-hundred sq ft mains probably don't have a much larger and docile reserve :P.

I think you might have missed some eras. The first 10 years after WWII saw the use of statlc line military rigs for freefall use, with somewhat marginal results. The safest thing to do would have been to use the gear for what it was designed for (static line jumps) - but people wanted to freefall.

The 70's saw a lot of drug and alcohol use in skydiving. That's where the term "safety meeting" came from. This dropped off quite a bit, but continues today in some places (ask around about "the sportsman's club" at a certain DZ.)

Today we have freeflyers who intentionally exceed the limits of their equipment and swoopers who jump canopies that are fatal if you make even a minor mistake. Safety is always an issue, but is often not stressed very hard (if at all.)

>When most recommendations for

Keep in mind that those altitudes were set given inaccurate skydiving altimeters, at freefall speeds, after a skydive. Exiting from an aircraft and opening immediately is a while different ballgame.

>I have not yet made a base jump. I would like to.

Beware, then, because there may be people out there who apply the same logic to you - "there's no logic in jumping without a reserve! There's a reason we have them, and jumping without one is idiotic."
