AOA devices, common on military and large civil aircraft, can be added to small planes to supplement airspeed indicators and stall warning systems, alerting pilots of a low airspeed condition before a dangerous aerodynamic stall occurs, especially during takeoff and landing Huh? I thought AoA instruments alerted pilots of a dangerous angle of attack - an angle surpassing the lift body's (wings) ability to create lift in excess of weight. OK I understand if you're not moving through the air most airplanes will not fly. But you can surely stall at 200 mph. So it's not about airspeed so much as AOA of the lifting bodies.
