Technique: Angle of attack

Angle of attack indicators allow pilots to fly with far more precision and peace of mind than by following the airspeed indicator. By flying an optimal AOA on final approach, for example, pilots don’t have to calculate the airplane’s weight or density altitude to avoid an aerodynamic stall. Flying the proper AOA also eliminates the hazard of flying too fast on final, which can result in runway overruns, prop or tail strikes, and needless go-arounds.
