What is the maximum acceptable descent rate during the final stages of approach under the stabilized approach concept?

The maximum acceptable descent rate during the final stages of approach under the stabilized approach concept is 1,000 feet per minute. This standard is established to ensure safety and stability during the landing phase of flight. A stabilized approach means that the aircraft is on the correct glide path, maintaining the appropriate airspeed, and has a consistent configuration (gear down, flaps set) as it approaches the runway.

Maintaining a descent rate of 1,000 feet per minute allows the pilot to have adequate control of the aircraft, making it easier to make any necessary adjustments to the approach. Higher descent rates could lead to a compromised ability to stabilize the landing, increase the risk of a hard landing, or complicate the pilot's ability to react to unexpected changes in the approach environment. Aiming for this descent rate aligns with safety protocols and best practices in aviation, ensuring pilots remain in control while preparing to land.
