At FL 110, what is the maximum holding speed for a jet transport aircraft?

In the context of holding patterns and the relevant regulations, the maximum holding speed for a jet transport aircraft below the altitude of 14,000 feet is crucial for ensuring safe operation within controlled airspace. Specifically, for altitudes up to FL 110, the limit is defined by speed in terms of Indicated Airspeed (IAS).

The regulation specifies that for jet aircraft operating at holding altitudes between 6,001 feet and 14,000 feet, the maximum holding speed is 230 knots IAS. This restriction is designed to maintain safe separation and control within the holding pattern, while accounting for the higher performance characteristics of jet transport aircraft.

Understanding that the indicated airspeed reflects the actual speed relative to the surrounding air, this speed is lower compared to true airspeed (TAS) under the same conditions. At FL 110 (11,000 feet), maintaining a maximum of 230 knots IAS helps ensure that all aircraft are operating within predictable flight parameters, which is particularly important in constrained airspace, such as near busy airports.

Ultimately, selection of this maximum holding speed is grounded in safety regulations that promote efficient air traffic management and mitigate the risk of compression or turbulence that could arise from excessive speeds in a holding configuration.
