What is the correct procedure to follow when executing a waveoff?

The correct procedure for executing a waveoff is to apply smooth power to maximum. This action is essential because a waveoff indicates that the landing is not to be completed, and the pilot must initiate a climb away from the landing approach. By increasing power smoothly to maximum, the aircraft can gain the necessary altitude and airspeed efficiently to transition into a climb.

Maintaining a safe climb path is crucial, as it ensures that the aircraft can clear any obstacles that may be present. Additionally, applying maximum power helps the pilot make a quick decision to abandon the landing and prepare for another approach if necessary.

The other choices do not reflect the correct response to a waveoff. For instance, reducing power would not support a safe ascent out of the landing environment. Similarly, setting the flaps for landing is inappropriate during a waveoff, as the aircraft should be configured for climb rather than descent. Lastly, maintaining altitude until instructed does not align with the proactive nature of a waveoff; instead, the pilot should be focused on climbing away from the situation safely.
