Which altitude is designated as the uncontrolled ejection altitude for warnings outside the FAF?

• A. 6000 feet AGL
• B. 6000 feet MSL
• C. 4000 feet AGL
• D. 2000 feet MSL

Answer: (A)

The concept here is how far above the ground the approach protection and warning perimeter is defined for segments outside the Final Approach Fix. The designated uncontrolled ejection altitude is given as 6000 feet above ground level, chosen so the warning system has a consistent, terrain-independent reference. Expressing it in AGL ensures that, regardless of how high or low the terrain around the airport sits, the same buffer is used to trigger warnings if you stray outside the FAF area. This provides timely, predictable alerts and helps you make safe decisions to rejoin or abandon the approach as needed. Using feet MSL would tie the warning threshold to the airport’s elevation and could either be too low or too high at different airports, reducing the effectiveness of the warning system. A lower AGL value like 4000 ft AGL or 2000 ft MSL would offer a smaller margin for error and could compromise safety on deviations outside the FAF.
