Recover from stalls shall be no lower than ______.

The correct answer indicates that a recovery from stalls shall be no lower than 1500 feet. This altitude is significant because it provides pilots with a safe buffer to recover from a stall without jeopardizing the safety of the aircraft.

Recovering from a stall at a higher altitude allows pilots to use time effectively to regain control of the aircraft and ensure that it has adequate space to maneuver and return to normal flight. The 1500-foot minimum is also aligned with standard operating procedures and safety recommendations from aviation authorities. This altitude ensures that in the event of a stall, pilots have enough height to recover without being at risk of hitting the ground or becoming unsafe if the aircraft experiences further complications during recovery.

Altitudes lower than 1500 feet may not offer enough time or space to execute a recovery effectively, potentially leading to dangerous flight situations. Therefore, this altitude requirement emphasizes the importance of safety and preparedness in flight operations, particularly during training and low-altitude maneuvers.
