Well, I was originally thinking along those lines, but since I could probably only afford one hot seat, the thought of the look of horror on my passengers faces after the pilot ejected changed my mind. g Remember to carry a camera to prove you were not flying the plane when it hit the school.

Introduction: Hello everyone.
"Don W" wrote I've no doubt that you can stop the prop. I'd still be concerned with some part of the chute getting wrapped around one or more prop blades causing a tangle or other malfunction. As I think about it, I wonder how Cirrus makes sure that they don't tangle in the vert or horz stabs. Its kind of the same problem. I think that the chute being blown out (along with the forward motion of the plane) would keep the chute under tension, which would at first be back and a little up, then as the forward speed drops, almost straight up. If that was true, you worry about the prop would be a non-issue, as long as you get the prop stopped. Of course, a side benefit to ejecting the engine is that you just got rid of 400-500 lbs which would otherwise be sitting behind the back passengers when you hit the ground. Also a non issue, I believe. The motion is almost staight down, while descending under the chute. The only thing to suffer at impact would be the ground underneath the plane. g -- Jim in NC |

Don't **** them off. they eat top posters like a Pratt & Whitney eats hi-test. It looks as if you may be a top poster, hence this warning. Govern yourself accordianly. Rich S. Indeed, a really big no-no!!!! The P&W sips daintily by comparison. ;-) Peter |

Introduction: Hello everyone.
----------snip-----------
Always wondered if a plane might could still be flown under minimal power while "on the chute". But it would probably collapse a round parachute... Richard Someone did that in a Cirrus. I believe that he powered away from a built up area and landed in the water. My further recollection is that some injuries occurred because the water landing prevented the undercarriage from absorbing the energy of the "landing"--like landing a parachute in a nearly seated position. :-( Peter |

Balistic Recovery Systems is the only one that I can recall, and they make them for a wide variety of aircraft and "ultralight vehicles". Their web address is http://brsparachutes.com/ Personally, I am NOT an advocate of the concept. I would prefer that the parachute be attached to ME, and NOT to @##$%& airplane. FIRE is the reason that comes most immediately to mind, but I suppose that I could think of more with a little effort. However, YMMV Peter |

I thought of that as well. It sure would get rid of a lot of weight, and you just put all the left over avgas away from you too. I don't think I'm smart enough to figure out the structure for the airplane+ escape pod though sigh. Also, did you notice that I figured out how to ditch the TIO-540 without using any pyrotechnics? I have a feeling that getting the pod off wouldn't be quite as simple. It sure would allow for a smaller chute though. Don W. |

. com... You wouldn't need a brake to get a fully feathering prop to stop. Even with the propeller stopped it seems that getting the chute to deploy without snagging risers on the prop would be problematic Don............ I see you did not pick up on my suggestion, so I'll take it one step further. If the *prop* is the problem, jettison the _________. (Fill in the blank) Rich "Engines are expensive, too." S. |
