In my opinion, certain contributors to this thread, have a very simplistic view on stalls in an aircraft....
Keep pulling, you see the line, that where's where it stalls
Don't forget an aircraft can stall at any attitude, and at any airspeed. The important thing to be aware of is that below Va the aircraft will stall before the wings fall off, above Va the wings might fall off first.
The only thing that detemins the stall is AoA....so if someone wants an AoA indicator, so what?
