If Low Key is at 1500 feet AGL, what is the minimum airspeed to maintain?

The minimum airspeed to maintain at 1500 feet AGL is significant for ensuring adequate control and safety during flight operations. In this context, 120 KIAS, identified as the correct answer, serves as a critical threshold that helps pilots establish and maintain a margin above stall speed, particularly in various configurations and flight conditions.

This minimum airspeed is often derived from the aircraft's performance data and operational guidelines, which are designed to provide a buffer against unintentional stalls during maneuvers. Maintaining this speed allows for improved responsiveness and stability, reducing the risk of entering into a situation that could lead to loss of control.

Setting airspeed too low, as might be the case with some of the other options, could potentially place the aircraft close to the danger zone where stall margin is compromised. Therefore, opting for 120 KIAS ensures that pilots operate within a safe envelope, particularly important in low altitude scenarios where maneuverability needs to be preserved, and time to respond to any unforeseen circumstances is limited.
