What action is taken immediately after establishing a positive rate during a go-around?

Establishing a positive rate of climb during a go-around indicates that the aircraft is safely gaining altitude, which is essential for the subsequent phases of flight. The immediate action taken after confirming a positive climb rate is to retract the landing gear, as this reduces drag and allows for a more efficient ascent. Retracting the gear contributes to improving the aircraft's climb performance and helps in transitioning to a stable climb configuration.

In this phase of flight, other actions, such as setting throttles to idle or deploying speed brakes, would hinder performance and is not appropriate at this critical moment. Flaps setting to maximum is also not standard procedure right after establishing a positive rate; rather, flaps are usually retracted in a controlled manner to continue the climb efficiently. This sequence ensures the aircraft maintains a safe and effective climb profile, transitioning smoothly back into the desired flight configuration.
