What is the minimum use elevation in feet AGL for precision approaches?

For precision approaches, the minimum use elevation is established at 80 feet AGL. This altitude is critical because it aligns with the operational safety standards required during the final phases of an approach, allowing pilots to effectively verify their visual references and confirm the aircraft's position relative to the runway. Approaching within this altitude provides adequate safety measures, ensuring that the aircraft is still at a sufficient height to execute go-around procedures if necessary. This standard is based on regulations and best practices that ensure pilots have the required time and situational awareness to make critical decisions during landing.

In precision approaches, the increased accuracy of the navigation aids, such as the Instrument Landing System (ILS), enables pilots to rely on both visual and instrument signals at this minimum height, fostering safer landings. The choice of 80 feet AGL efficiently balances safety and operational integrity, making it an essential aspect of flight training and procedure protocol for pilots operating in various conditions.
