What is the primary purpose of a waveoff during landing operations?

The primary purpose of a waveoff during landing operations is to ensure safety in landing. A waveoff is a crucial maneuver that indicates a pilot must abort the landing approach and climb away from the runway. This can occur for a variety of reasons, such as an unsafe condition on the runway, insufficient separation from other aircraft, or a missed or misaligned approach. By executing a waveoff, the pilot prioritizes safety, allowing for reassessment of the situation before attempting another landing.

Adjusting speed is not the central focus of a waveoff; rather, it is a signal to climb and reposition rather than to modify the descent rate or airspeed. Redirecting back to the runway is a result of the waveoff, as it often leads to a re-approach, but the main intent remains on maintaining safety. While communication with the tower is important in the larger context of operations, the waveoff itself is an action taken by the pilot in response to situational safety concerns, rather than a direct communication protocol.
