What is the minimum height for autopilot use in visual and non-precision approaches?

The minimum height for autopilot use during visual and non-precision approaches is typically set at 400 feet AGL. This height ensures that the pilot has sufficient situational awareness and control over the aircraft when transitioning from autopilot to manual control. At this altitude, pilots are still within a range that allows for effective monitoring and adjustment of the aircraft's alignment with the runway.

In visual approaches, having the autopilot disengage above this altitude can allow for better decision-making as the pilot visually acquires the runway and surrounding landmarks. Non-precision approaches, which may lack a reliable glideslope signal, still require significant pilot involvement, making 400 feet AGL a prudent minimum for ensuring safety and efficacy in the final approach phase. This height effectively balances the automation-versus-pilot-input dynamic, allowing for automation benefits while also emphasizing the pilot's responsibility in the landing process.

Understanding this minimum height is critical for flight safety and compliance with regulatory standards in aviation operations.
