Go-Around (GA) mode button is used in case of a missed approach. Which option reflects the correct label for this mode?

• A. LOC
• B. MISS
• C. CMD
• D. GA

Answer: (D)

Go-around is a specific action to safely abort a landing and climb away to reattempt the approach. In autopilot and flight‑deck systems, the labeled button for this action is GA, short for Go-Around. Pressing it switches the autopilot into go-around mode, commanding a rapid climb and thrust increase to reach the missed‑approach altitude and configuration.

The other labels correspond to different functions: localizer (LOC) is for capturing the runway’s localizer during approach, not for initiating a missed approach; Miss or MIS/missed approach is not the mode label used on most autopilots; CMD isn’t the go-around command. So GA is the correct label because it specifically denotes the go-around action described.
