Cool, thanks guys. Are there any systems that have airbags come out of the actual frame, like some cars have from the door pillars in addition to the steering wheel? How much evidence is there of their worth overall in light aircraft?

Quoting RussianJet (Reply 4): How much evidence is there of their worth overall in light aircraft?
Obviously if you plummet into the ground at 150 knots an airbag isn't going to help much. However in general aviation lots of accidents are low speed, for example when making an emergency landing in a field and running into a cow at 20 knots. At that point airbags are presumably quite useful.

Most light aircraft don't have a convenient mounting location on the instrument panel for an airbag. You can't really mount it in the yoke, since the yoke would move during deployment (and I'd hate to see what would happen during an accidental deployment close to the ground...) Therefore, the seat belt is really the best place to mount them. All Cessna 172SPs I've flown feature the airbag in the seat belt - it's not a bad design either, it's comfortable and really not that noticable when in place.
Cirrus types are some of the best equipped GA aircraft when it comes to survivability. In addition to the CAPS airframe parachute systems, most Cirrus come equipped with airbags of various types, and all come equipped with "CEATs" (Cirrus Energy Absorbing Technology) seats. The CEATs technology essentially mounts the seats on collapsible high density honeycomb blocks. The blocks are designed to crush vertically and lessen the vertical deceleration forces transmitted to the occupants in a crash. Since humans are far more sensitive to vertical acceleration than transverse, I personally feel more comfortable with a well designed (controlled deformable) seat in conjunction with a four or five point seat belt than I would feel with simply an air bag.

We have the AMSAFE airbags in my University's Cessnas. My safety class had the whole technical rundown but I can't remember it too well. You just have to make sure the seatbelt is facing the proper direction or else it isn't going to work very well. I know at least at my university it saved someone from extreme injury. A student was climbing out of KPKD at night and got the sensation he was moving too slow even though his airspeed indicator said 74 knots, which is the standard climb rate. Well he pushed the nose down and went right into the ground. He ended up with just a few bruises and ultimately a bruised ego. Better than dash rash.
