What are the steps involved in a go-around procedure?

The go-around procedure is a critical element of flight operations performed when a landing approach needs to be aborted for various reasons, such as unstable approaches, runway obstructions, or other factors that necessitate a climb away from the landing approach. The correct steps involved in a go-around procedure include disengaging the autopilot to allow greater manual control over the aircraft, adding power to initiate the climb, maintaining an appropriate climb speed to ensure the aircraft remains in a safe flight envelope, and retracting the landing gear once the aircraft has established a positive rate of climb.

This series of actions directly contributes to a safe and effective go-around, ensuring the aircraft can smoothly transition from landing to climbing without jeopardizing its performance capabilities. The focus on maintaining climb speed and retracting the landing gear at this stage are essential to managing the aircraft's lift and drag, thus allowing for a safe ascent.

The other options presented involve actions or procedures that do not align with the standard and effective go-around practices. For instance, lowering landing gear or engaging autopilot during a go-around can pose risks, as the conditions may not be suitable for these actions until the aircraft has stabilized in the climb.
