How long is the inbound leg timing for holding patterns above 14,000 feet?

In standard holding procedures, the timing for the inbound leg of a holding pattern is generally determined by the altitude of the aircraft. For aircraft operating above 14,000 feet, the recommended timing for the inbound leg is typically 1.5 minutes. This longer duration is designed to allow for the increased ground speed that usually accompanies higher altitudes, ensuring that pilots maintain the appropriate spacing and track closely to their established holding pattern. This timing is codified in AIM (Aeronautical Information Manual) guidance, which helps ensure consistency and safety in navigation during holding patterns. The selection of 1.5 minutes reflects the need to accommodate performance variations inherent at higher altitudes.
