At what altitude should a takeoff-flap landing arrive at the 90 position in the pattern?

The correct altitude for a takeoff-flap landing to arrive at the 90 position in the pattern is 450 feet AGL. This altitude is important because it allows for a proper configuration of the aircraft and facilitates a comfortable and efficient approach to landing.

At 450 AGL, the pilot can effectively manage the aircraft's energy and descent rate, ensuring that there's adequate time to assess the landing environment. Being at this altitude also gives the pilot a buffer for any adjustments that may be needed regarding airspeed and configuration for a successful landing.

Arriving at this altitude allows pilots to comfortably execute their landing checklist and make necessary adjustments to their flight path while maintaining situational awareness of other traffic and the runway environment. This practice contributes to a safe and systematic landing approach.
