What should a pilot do if ATC issues a "Go-around" instruction?

When Air Traffic Control (ATC) issues a "Go-around" instruction, it signifies that the pilot should abort the landing attempt, typically due to safety concerns such as obstacles on the runway, unexpected changes in traffic, or unsuitable approach conditions. Executing the go-around procedure immediately is the proper response, as this procedure ensures that the aircraft regains the appropriate altitude and configuration to safely navigate away from the runway.

Conducting a go-around involves a series of predetermined steps like applying full power, retracting the landing gear if it was already down, climbing to a safe altitude, and communicating with ATC regarding the intention to circle back for another approach. This instruction emphasizes the priority of maintaining safety over any other considerations.

The other responses don't align with proper aviation protocol in this situation. Continuing the landing without assistance ignores the directive from ATC, which is aimed at preventing potential accidents. Increasing airspeed for landing would not be appropriate as it may interfere with safely executing the go-around. Lastly, waiting for further instructions from ground control fails to address the immediate need for action once a go-around is called. Each of these alternatives could compromise safety, underlining why adhering to the go-around protocol is essential.
