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

When maintaining pattern interval becomes impossible during an approach, the appropriate action is to execute a waveoff. A waveoff is a command or decision made to discontinue the landing approach and climb away from the runway.

This action is crucial for ensuring safety, especially in situations where the spacing between aircraft becomes compromised. If safety cannot be maintained due to a lack of separation, executing a waveoff allows the pilot to gain altitude, reassess the situation, and rejoin the traffic pattern when it is safe to do so.

While continuing with the landing or performing a go-around may seem like alternatives, they do not address the situation where maintaining the proper interval is deemed impossible. Adjusting power settings alone would not resolve the underlying issue of spacing and could lead to more severe problems. A waveoff represents a clear and decisive action to ensure safety in the approach phase.
