What is the appropriate action regarding carb heat during a waveoff?

When executing a waveoff, or go-around procedure, it is crucial to ensure the engine operates at peak performance for the climb. During this phase, the application of carb heat is typically set to the "off" position.

Carburetor heat is used primarily to prevent ice formation in the carburetor, which can occur during idle or low power settings. Since a waveoff demands full throttle and requires immediate climb performance, keeping the carb heat off maximizes engine output and airflow. Unless there are specific conditions indicating carb ice – such as visible freezing temperatures or high humidity – the best practice is to avoid using carb heat during the waveoff.

Adhering to this practice helps ensure that the engine functions efficiently, allowing for a more effective climb out of the go-around.
