In a holding pattern, what is the typical duration of one complete circuit?

In a holding pattern, the typical duration of one complete circuit is approximately 1-2 minutes. This time frame is established to ensure that aircraft maintain efficient spacing and do not hold longer than necessary, which is crucial for maintaining air traffic flow. The 1-2 minute duration is generally sufficient for pilots to complete their turns and regain altitude if needed, while still being manageable in terms of fuel consumption and aircraft performance.

Holding patterns are designed with a standardized entry and exit procedure which allows pilots to follow specific timing guidelines based on the aircraft's speed. This ensures that all aircraft operate within a predictable framework, enhancing safety and efficiency in busy airspace. While longer holding durations can occur under certain conditions, they are not typical in standard operational procedures.
