The chute is a Strong 303 backpack manufactured in 10/94, so its 16
years old. Some re-packers have been know to impose a 20-year life limit which is not in the FAR's........a carry-over from the military, and we all know who pays for their new chutes ($1985 if you please) as far as the Feds are concerned, a chute is good to go as long as it passes inspection, kinda like our sailplanes. Wouln't it be a bitch if we had to ****can our sailplanes at 20 years? As for two parachutes, I have picked the best option IMHO and I will go with that. Kinda like wearing a belt and suspenders, isn't it? Cheers, JJ PS, I'm looking forward to a very comfortable seat in the future. |

Bad things start happening... you pull the lever. I would not sit around hoping they don't get worse and I don't know the maximum operating speed of JJ's BRS systems but our slippery little toys likely can reach that fast and if they do its too late. Unfortunately exceeding the speed limits of BRS systems has cost several GA pilots their lives. Personally I would not trade a backpack parachute for a BRS system. In addition to ... yes (if fitting a BRS to my glider was an option at all). JJ is in the lucky position of having a glider designed to take a BRS system. Still I'd really like to know the BRS system being fitted has been test fired in that exact glider type and demonstrated to work well and I'd really want to understand the use/survival envelope (max airspeed, min altitude, descent fuselage angle, descent rate etc.).

The difference with an out of control glider falling through a gaggle is that it may be possible to avoid it. Also, if there is a collision with that out of control falling glider the hit pilot stands a reasonable chance of bailing out if not incapacitated by a direct hit to the cockpit. If a glider ahead and below deploys a BRS you won't stand a chance of avoiding it and, if the canopy envelopes the cockpit, I doubt it would be possible to get out. Andy |

![]() OK, there your are, upside down, half a wing missing, on your way down through a gaggle of 20 gliders. Is it better to pop the BRS right away (maybe get someone with your chute), or wait till you are below the gaggle (maybe hit someone(s) at high speed on your way down)? Oh my, where to start? First off, this ain't my first rodeo, I have been through this drill twice while doing my civic duty in the USAF and believe my, delaying pulling the handle was the last thing I considered. The problem that really worries me is a midair in the pattern. I almost had a head-on midair just after calling down-wind with a fellow who didn't feel it was necessary to tell me he was entering the pattern also, but in the opposite direction! If we had collided, there is no way either of us would have made it, period, end of discussion! Deploying a BRS in this situation, could save a life.............mine! They have conducted 35 airborne tests to establish maximum weight and speed parameters. The system I selected is 200 pounds under the max wt with a max deployment speed of 138mph. The nose will pitch up on deployment, so the sooner the better in this regard..........don't want the canopy to fail or to loop up into the deployed chute. Conclusion, don't delay pulling the little red handle! BRS tests have shown the system could work as low as 260 feet depending mainly on aircraft attitude on deployment (rocket fires up). Descent rate of 15-28f/s depending on wt and density altitude, lets use 22f/s, thats like jumping off a 7 foot ledge or being involved in a fender-bender at 15mph. Descent attitude on the Genesis is 40 degrees nose low due to the hatch being aft a bit. I would expect the nose wheel to absorb half the impact with the main gear taking the rest with some structrual damage, but I know a good A&P who works cheep. Where in any of the above do I; tidy up the cockpit and step smartly over the side wearing my back-pack? :) JJ PS the Strong is sold. |

Additional advantages: other pilots will be less likely to leech - or thermal in the blind spot above and behind you. 9B |

Thank you JJ.
I was wondering how long it was going to take for the "Black Ace" to let people know that he understands what it is like to leave an aircraft in an emergency.
