What altitude is specified for a no-flap landing when reaching the 90 position?

For a no-flap landing, reaching the 90-degree position typically occurs at an altitude of 450 feet above ground level (AGL). This altitude is important for managing the approach and ensuring the aircraft is in the correct configuration and speed prior to landing.

At 450 AGL, the pilot can effectively gauge the aircraft's descent path and make necessary adjustments to maintain a stable approach. This altitude provides enough time for the pilot to evaluate their landing alignment, correct any drift, and prepare to execute the landing procedure without flaps. Pilots are trained to maintain specific altitudes during various phases of flight to enhance safety and performance, and the 90-degree position at 450 AGL is a key component of achieving a successful no-flap landing.
