What is the maximum acceptable descent rate during the final stages of a nonprecision approach below 1,000 ft. AGL?

The maximum acceptable descent rate during the final stages of a nonprecision approach below 1,000 feet AGL is established to ensure safe and controlled descent, particularly as the aircraft approaches the runway. A descent rate of 1,000 feet per minute (fpm) is commonly used as it allows pilots to maintain both adequate vertical speed and the necessary situational awareness needed for landing. This descent rate provides a balance between efficiency and safety, allowing pilots to make necessary adjustments in altitude and align with the runway while minimizing the risk of excessive descent that could lead to unstable approaches or potential hazards.

In contrast, rates higher than 1,000 fpm would not provide sufficient time for pilots to respond to changes in the approach situation or to stabilize the aircraft, especially in the critical phase of landing. Therefore, adherence to a maximum descent rate of 1,000 fpm aligns with established procedures and best practices within aviation standards for nonprecision approaches.
