What is the maximum holding airspeed for altitudes above 14000 feet MSL?

The maximum holding airspeed for altitudes above 14,000 feet MSL is 265 KIAS. This standard is established to ensure that aircraft maintain a safe and efficient speed during holding patterns at higher altitudes, which can include increased winds and other factors that might affect aircraft performance.

At greater altitudes, the air density decreases, which impacts lift and drag characteristics of the aircraft. The increase in maximum airspeed allows for better maneuverability and helps ensure that aircraft can comply with holding procedures without excessive fuel consumption or strain on the aircraft. The holding speed limits are designed to facilitate safe separation and efficient air traffic management. Hence, for aircraft operating in holding patterns at altitudes above 14,000 feet, flying at a maximum speed of 265 KIAS is in line with standard operational guidelines.
