I don't wish to appear cynical, and I certainly do wish to provide all theprotection for the pilot (me) and any passengers, and certainly some verygood advice on secure attach points has been provided, but....Just how much security can we expect from our harnesses? Surely we don'twant to get bucked out of the airplane in rough air, nor do we want to fallout in a poorly executed loop, but will our harness really protect us in acrash? Somebody mentioned 20 g's. I'm pretty sure our bodies would explodeinternally in 20 g's, plus the airframe itself would disintegrate. Thinking that the truth lies somewhere between here and there, can someoneeducate me on the thought process going into designing an attach point?Gary Boothe Cool, CA WW Conversion 90% done, Tail Group awaiting hinges,working on fuse(6 ribs down...)>________________________________________________________________________________Subject: Pietenpol-List: Cubs and ChampsDate: Fri, 11 Apr 2008 13:46:12 -0500

Actually all newly certified airliners have 16G seats with the correspondingincrease in floor strength because people can and do survive those kinds ofmomentary loads providing they are restrained properly and don't hit theirheads on anything hard.Bob-----Original Message-----

I have to agree with Mike C on this one. We all have flown Cubs and Champs and thought nothing of the fact that they have no shoulder harnesses. All due respect to those that have done so, but I am scared of attaching a shoulder harness to the cabanes, especially at the top. In any accident, it is a high probability that a wing is going to hit SOMETHING, and I can see the wing wrenching backward and strangling someone with the cable/harness.I am currently wrestling with the lap belt attachment for the front seat. The best idea I can come up with is a steel strap bent 90 degrees and bolted through the ash cross piece and floorboard. With a large washer on it, you are not going to pull it out. I plan to have the steel strap bolted just outboard of the rear seat leg, then run up the leg with a bolt through it and the leg. Up at the top, I will have the seat belt itself attached to the strap (with a doubler) This will keep the belt out of the pilot's feet. This is the best idea I can come up with, but always willing to listen to others.Gene (back from Sun n Fun and dying to go to the hangar and get back on the Piet)________________________________________________________________________________Date: Fri, 11 Apr 2008 17:39:02 -0400
