What action should be taken if maintaining pattern interval becomes impossible during approach?

When maintaining pattern interval becomes impossible during the approach, performing a waveoff is the appropriate action. This maneuver allows you to safely exit the current pattern and gain altitude, typically while executing a go-around procedure. A waveoff is essentially a signal or decision that indicates to air traffic control and other pilots in the area that you are unable to maintain a safe separation from other aircraft.

Executing a waveoff allows you to reassess the situation, maintain safety, and avoid potential conflicts. This action is critical in busy airspace where multiple aircraft may be operating in proximity during approach and landing phases. It ensures that safety is prioritized, as continuing to land under precarious conditions could lead to collisions or other hazardous situations.

In contrast, continuing to land when a proper interval cannot be maintained, or simply making adjustments to power settings, could compromise safety and lead to an undesirable outcome. While a go-around is also a valid option, the term waveoff specifically covers the action of ceasing the landing attempt and can often imply immediate adjustments to navigate safely.
