Also, as a skydiver with 1000+ jumps, glider, and recreational aerobatic pilot I highly recommend that you go through a basic jump course and at least a few levels of AFF or static line training at least to the point where you feel comfortable with getting out of an aircraft and opening the parachute on your own. There's no point in having a parachute if you are too scared or don't have the proper training to use it. At the moment of truth, if you ever need to use it, you want to have all the cards stacked in your favor. This recommendation seems reasonable, but I wonder if there is any research, even just an informal survey, that provides evidence for it. After all, the suggestion is about 4000 USA glider pilots should make several parachute jumps to improve the outcomes of the bail-out from a that happens every two three years. My fuzzy recollection of the last 30 years is that any pilot that gets out of the glider has a pretty good outcome, meaning no or small injuries. In other words, we'd be risking injury or worse from 8000 to 12,000 practice jumps to make 3 or 4 bail-outs come out a little bit better. Perhaps my recollection is wrong. Are there pilots with no parachute training that bailed out of a glider, then made some practice jumps afterwards so they'd be better prepared if it happened again? Are there pilots that did have parachuting training before they bailed out of a glider in an emergency, and were damn glad they had the training? -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * Updated!

I don't have a specific suggestion, but do recall from my time flying a
K6cr that the seat back has a well for the parachute to sit in, and that the headroom between me and the canopy (I'm 6ft 1in = 1.85m) was minimal. Both these suggest a backpack parachute rather than one with a built-in seat cushion. As to which backpack type, ideally find as many pilots at your airfield as have parachutes and ask them to let you try them out in your cockpit (as advised in a previous thread). vontresc wrote: On Mar 16, 1:31 pm, Marc Ramsey wrote: Darryl Ramm wrote: And I brought the same long-softie for possibly the same glider a DG-300/303, on recommendation from possibly the same rigger.

Does the lower descent rate also mean you might dragged more after landing in windy conditions? -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * Updated!

some emergency parachutes "can be" fitted with square (ram air) parachutes,
these are only for certified jumpers who have experience in this type of parachute. However, it also should be noted that square parachutes do not function like round or conical parachutes, they don't open reliably unless you are in a stable position, something you likely will not be in immediately after a bail out and may never be in if you're not an experienced jumper, more likely you will exit and emergency bail out tumbling and even with experience you may be disabled and unable to enter into a proper PLF position for deployment. The standard round canopies used in most emergency parachutes are extensively tested to open for all positions, in all imaginable conditions, even soaked wet, mispacked or other... the landing with a ram air parachute is also much like flying....they can be flown very fast, slowed, even stalled (though for emergency use they would be less controllable to limit these) you need to learn to flare at the correct time to make that soft airshow like stand up landing, otherwise your landing can be pretty eventful.....(ever notice how many at the local jump site are wearing casts or walking with crutches? ![]() So IMHO and in the opinion of most manufacturers the ram air canopies have a place, but not typically in emergency pilot rigs.

"Because of the advanced characteristics of these canopy designs, the Sport Aviator model may only be used by individuals who either have ram-air jumping experience such as skydiving, or have received special training in the use and performance of these canopies." and.... "The heart of the system is the P-124 ram-air canopy which is designed for use by airmen who may have no prior jump experience or who may even be incapacitated to some degree." Which is it? Both are referring to the P-124 canopy design. |

Are there pilots that did have parachuting training before they bailed out of a glider in an emergency, and were damn glad they had the training? I don't fit either category since I never jumped out of an aircraft in an emergency. I do have several hundred hours flying jump planes and have made about 50 jumps. Point 1 - Almost all sport jumping is done with ram air parachutes that can be steered and flared. I doubt that any canopy experience with these has much benefit for an emergncy landing under a round. Point 2 - Almost all glider emergency parachutes are rounds. I know of a few pilots, one with no jump experience at all, that use ram air emergency chutes. I also know of a least one very experienced jumper who would never consider using a ram air emergency chute in a glider. Point 3 - The biggest advantages of jump experience may be less fear exiting the aircraft and more stable position on opening. I watched lots of first time jumpers exit my aircraft. The thing that impressed me most was that I never saw a malfunction despite the horrible positions sometimes adopted after leaving the strut. So my priorities would be: 1.Familairity with my own emergency chute particularly what I have to do to turn it into the wind. 2.Getting ground training in parachute landing fall technique. 3. Getting an actual jump, but just because it's fun (until you break something) I know one pilot that baled out over Arizona. He was so calm and collected he spent most of the descent trying to get nice and stable and nearly hit the ground before he pulled. There are no style points for the jump, get it open. Andy |

who would never consider using a ram air emergency chute in a glider. I am a very experienced jumper (known by Andy) and I would never consider using anything BUT a ram air emergency chute in my glider. With appropriate wing loading, of course! 2NO |
