When more than one circuit of the holding pattern is needed, what must the pilot do?

When a pilot determines that multiple circuits of the holding pattern are necessary, it is essential to communicate with Air Traffic Control (ATC) for approval. This process ensures that ATC is aware of the pilot’s intentions and can make any necessary adjustments to the traffic flow and separation from other aircraft. ATC maintains a comprehensive view of airspace usage, and changes to a flight's planned route, including additional holding patterns, should be coordinated to maintain safety and efficiency.

Notifying ATC allows them to provide essential updates, potential changes to the holding pattern, or instructions on how long the pilot may remain in the holding pattern without affecting other traffic. Professional communication with ATC is a fundamental aspect of aviation safety and operational procedures.
