What is the outbound time in a holding pattern above 14000 ft in still air conditions?

In a holding pattern above 14,000 feet in still air conditions, the outbound leg time is designed to provide sufficient spacing for aircraft to ensure they remain within safe operating margins. The standard time for an outbound leg in these conditions is 1 minute 30 seconds.

This duration allows for a proper approach and stabilization of the aircraft during the hold. The specific timeframes are based on FAA and international regulations, which establish standardized holding pattern procedures to ensure flight safety and efficiency.

The other durations such as 1 minute, 2 minutes, and 2 minutes 30 seconds do not align with the established standards for holding patterns at altitudes above 14,000 feet, as they either do not accommodate enough time for managing the aircraft's distance from the holding fix or are too lengthy, leading to potential airspace congestion around the holding area.
