At what altitude should landing gear be retracted according to performance data?

The correct altitude for retracting the landing gear is 50 feet above field elevation, as suggested by performance data. Retracting the landing gear at this altitude strikes a balance between safety and performance optimization. At 50 feet, the aircraft is typically in a stable climb phase following takeoff, which allows for smooth retraction without compromising the aircraft's ability to maintain a positive rate of climb.

Retraction at this altitude also minimizes drag effectively, enabling the aircraft to gain speed and altitude more efficiently, improving overall climb performance. If the gear were to be retracted too early or too late, it could lead to increased drag or a potential loss of control during a critical phase of flight. Therefore, adhering to the performance data regarding gear retraction at the designated altitude is vital for operational safety and efficiency.
