What is the descent rate requirement for a stabilized approach at 1000 feet above TDZE?

The requirement for a stabilized approach dictates that the descent rate should be less than 1000 feet per minute when the aircraft is at or below 1000 feet above the touchdown zone elevation (TDZE). This limit is established to ensure that the aircraft is in a controlled flight profile, allowing pilots to make necessary adjustments to airspeed and configuration while maintaining a safe approach path.

A descent rate exceeding this threshold could indicate an unstable approach, increasing the risk of an unsafe landing due to insufficient time to react to any potential issues or to make corrections. Maintaining a rate of less than 1000 feet per minute ensures that pilots can effectively manage the descent and keep the approach within safe operating parameters, leading to smoother landings and better overall flight safety.

This stability is critical not just for safety but also for passenger comfort and confidence during the final stages of the approach.
