Steep turns should be performed at no less than:

Steep turns should be performed at no less than 1,500 feet above ground level (AGL) primarily for safety and practical operational reasons. When conducting steep turns, the aircraft experiences increased load factors and requires a higher altitude to ensure adequate vertical separation from the ground in case of unexpected situations that may arise during the maneuver.

Performing steep turns at or above 1,500 feet provides sufficient altitude to recover and maintain control of the aircraft if there are any issues, thus enhancing safety. Additionally, this altitude allows pilots to practice the maneuver without the immediate concern of terrain or obstacles that could complicate recovery actions. The aim is to ensure that pilots can execute these maneuvers proficiently while maintaining a safe margin above the ground.

Lower altitudes, such as 1,000 feet AGL or below, do not provide enough space for recovery in the event of a stall or loss of control, making 1,500 feet the minimum safe altitude for steep turns. This consideration aligns with standard operating procedures and best practices for flight training and maneuver execution.
