What is the term for flying in a set pattern until cleared to land?

The term used for flying in a set pattern until cleared to land is referred to as "circling." When an aircraft is instructed to circle, it typically means that they cannot land immediately due to various reasons, such as traffic congestion on the runway or unfavorable weather conditions. During this maneuver, pilots adhere to specific flight patterns to maintain safety while waiting for clearance to descend and land. This term is widely understood in aviation and among pilots, as it describes the need to remain in a holding pattern, often at a specific altitude, until further instructions from air traffic control are provided.

The other terms mentioned do not accurately describe this situation. For example, "connection" refers to a transfer from one flight to another, while "delayed flight" indicates that a flight doesn't depart or arrive as scheduled. "Deplane" simply means to exit the aircraft after landing. Thus, "circling" is the precise term that conveys the action of waiting in a specific flight pattern before landing.
