What does the green arc on the AOA gauge indicate?

The green arc on the AOA (Angle of Attack) gauge signifies the optimal range for angle of attack during flight, specifically indicating a range of 10 to 11 units. This range is crucial for pilots to maintain effective lift while ensuring that the aircraft is operating within safe parameters. Operating within this green arc helps prevent aerodynamic stall and promotes efficient flying conditions, which is particularly important during critical phases of flight, such as takeoff and landing.

Maintaining an AOA within this optimal range contributes to better control and overall performance of the aircraft, allowing pilots to manage the lift effectively without compromising safety. The choice of 10 to 11 units encapsulates the zone where the aircraft experiences maximum lift with appropriate handling characteristics, making it essential knowledge for flying the T-6A safely and effectively.
