What is the flap retraction altitude in normal conditions?

The flap retraction altitude in normal conditions is typically set at 1,000 feet AFE (Above Field Elevation). This altitude is established to ensure that the aircraft has sufficient altitude and speed to safely retract the flaps after takeoff, enabling a smoother transition to climb. By waiting until reaching this altitude, pilots can ensure that the aircraft is flying at a stable speed and can maintain safe control during this critical phase of flight.

Opting for flaps at a higher altitude allows for added safety margins, as it provides ample time to address any potential issues while the aircraft is still at a manageable altitude and speed. In addition, the 1,000 feet AFE alignment with common performance guidelines helps maintain compliance with safety regulations and operational standards that govern aircraft takeoff and climb procedures.
