Default RV "Hitting a Wall"...

Even if you "hit a wall", you still might be okay! In mid-2000's an RV-6 hit a parked dump truck in a Dept. of California parking lot, yet both pilot and pax survived! Upon impact, their bodies were thrown forward which pulled on their shoulder straps and transferred the deceleration G load to the tail cone where the steel wires attach. This pulled the tail cones together, and when they got to the point where they couldn't do that any more, the double row of rivets (that attach the baggage area fwd fuselage to the tail cone), all sheared off! This then allowed the tail cone to slide forward, and both pilot and pax received deep lacerations when their heads hit the metal front edge of the instrument panel cover; but they did thankfully survive. Just shows how important it is to properly control the aircraft all the way to the flare, and not allow it to hit hard which is never good on internal organs!

thread drift. the glare shield edge should make us aware of danger. this may not be the final solution but it may help. a hard round shape. an idea stolen from Kevin Horton.

Default RV 9A brs

Aero classic makes an excellent cushioned edge for the instrument panel edge. I installed one. Very easy. Looks good.

Coming back to the idea of a parachute, this video, showing the ground test of the BRS installed in the Glasair Sportsman, gives an idea of the energy involved in firing the parachute rocket.
