What does ACA(H) stand for and what is its purpose?

• A. Asymmetric Committal Altitude; minimum height to establish a positive climb while maintaining adequate speed for control and removal of drag during an approach
• B. Asymmetric Climb Allowance Height
• C. Actual Climb Altitude
• D. Automatic Climb Height

Answer: (A)

ACA(H) defines the minimum height at which, if you have an engine out, you can safely commit to a climb during the approach and still have enough airspeed to control the aircraft and overcome the extra drag from the approach configuration. This threshold ensures you can establish a positive climb promptly, preserving safe flight path and usable control as you transition from approach to a climb. The wording of this option directly captures the purpose of maintaining control authority and shedding drag in an asymmetric (engine-out) scenario on approach. Other terms shown aren’t standard or don’t describe the engine-out climb requirement during approach, so they don’t fit the situation.
