Max holding speed at USAF airfields is capped at what speed unless depicted otherwise?

The maximum holding speed at USAF airfields is capped at 310 KIAS unless otherwise depicted. This regulation is in place to maintain safety and efficiency in controlled airspace, ensuring that aircraft are able to hold at designated waypoints without excessive speed that could lead to spacing issues or increased workload for air traffic control.

Holding patterns typically require aircraft to maintain steady, manageable speeds, allowing for safe separation from other traffic and facilitating smooth flow during times when landing options may be limited. The 310 KIAS limit aligns with operational needs while accommodating variations in aircraft types and performance capabilities. In the absence of specific instructions or charted limitations that indicate otherwise, this speed serves as a standard for pilots operating in these airspace environments.
