How long is the inbound leg of a holding pattern above 14,000 feet according to standard no-wind conditions?

In standard no-wind conditions for holding patterns, the inbound leg time is essential for maintaining the desired spacing and ensuring aircraft separation. For altitudes above 14,000 feet, the correct duration for the inbound leg of a holding pattern is indeed 1.5 minutes (1 minute and 30 seconds). This timing is established to allow for the aircraft to adequately complete the hold without excessive maneuvering, thereby maintaining safety and efficiency in the airspace.

The 1.5-minute inbound leg provides an appropriate amount of time for the aircraft to stay on the specified track, especially at the higher altitudes where it is important to consider factors such as airspeed and the possible effects of wind. This duration helps pilots effectively manage their descent or approach, making it a crucial part of air traffic control procedures and situational awareness during holding patterns.
