For a takeoff flap landing, what altitude should you be at when arriving at the 90 position in the pattern?

For a takeoff flap landing, the correct altitude to be at when arriving at the 90-degree position in the traffic pattern is 450 feet AGL (Above Ground Level). This altitude allows for an optimal configuration and decent margin for maneuvering during the approach.

At 450 feet AGL, the aircraft is in a good position to manage its descent and speed as it prepares for the final turn toward the runway. This altitude provides ample time for the pilot to assess the approach, make any necessary adjustments, and execute the landing procedure while maintaining a safe environment.

Choosing an altitude significantly higher or lower than 450 feet AGL may lead to difficulties in managing the aircraft's speed and configuration, potentially compromising safety and stability during the landing sequence. The altitude recommended facilitates a smooth transition into the landing phase while ensuring that the pilot stays within a desirable performance envelope.
