What value does the white triangle on the AOA gauge represent?

The value represented by the white triangle on the Angle of Attack (AOA) gauge is a critical reference for pilots, indicating the optimal angle of attack for maintaining controlled flight and preventing a stall. Specifically, the white triangle signifies 4.9 units, which is the angle at which the aircraft performs best concerning lift and drag, providing a margin of safety against stalling while allowing efficient aircraft performance.

Understanding the significance of this value is essential for pilots, as it aids in maintaining precise control during various flight maneuvers and maneuvers near stall conditions. This reference plays a pivotal role during takeoff, landing, and in situations requiring close monitoring of performance and safety parameters.

The other values listed do not correspond to the white triangle indicator. This distinction reinforces the importance of recognizing specific instrumentation markers in the cockpit, as they convey essential information that supports safe and effective flying.
