On precision approaches or approaches with vertical guidance, what is the minimum altitude for autopilot use with one engine inoperative?

• A. 90 feet AGL
• B. 110 feet AGL
• C. 130 feet AGL
• D. 150 feet AGL

Answer: (B)

The situation tests autopilot use limits when you have an engine out on a precision approach or an approach with vertical guidance. The requirement is that you may rely on the autopilot down to a minimum altitude of 110 feet AGL. This height gives a safe margin to monitor performance, verify configurations, and either continue manually if needed or transition to a go-around or landing without rushing. Dropping below this altitude would leave too little time and height to manage an OEI situation safely, while higher numbers aren’t the floor you must meet—110 feet is the mandated minimum.
