What behavior is expected from the aircraft when the green arc is displayed on the AOA gauge?

When the green arc is displayed on the AOA (Angle of Attack) gauge, it indicates that the aircraft is operating within the normal range for approach and landing. This area signifies that the angle of attack is within the optimal limit for maintaining lift without approaching stall conditions.

During landing, pilots are trained to aim for this specific range to ensure adequate lift and control while minimizing the risk of stalling. The green arc helps prevent exceeding angles that might lead to insufficient lift and potential safety hazards, particularly in the critical phases of flight like landing. Therefore, the presence of the green arc directly corresponds to executing a normal approach to landing, ensuring that the aircraft remains in a safe, controlled flight regime as it descends towards the runway.
