What is the maximum speed allowed while holding below 6,000 feet?

The maximum speed allowed while holding below 6,000 feet is 200 knots. This is primarily a safety regulation established to ensure safe separation between aircraft operating in controlled airspace, considering the potential for encountering turbulence and the performance capabilities of smaller aircraft that may be operating below this altitude. The option of 200 knots is aligned with standard procedures adopted within the aviation community, which seek to maintain flight safety, manage airspace congestion, and provide a buffer that accommodates the varying rates of climb and descent for different types of aircraft.

Other speed limitations in different contexts, such as 230 knots for certain portions of airspace or 250 knots below 10,000 feet, are applicable outside of holding patterns or may depend on specific air traffic control instructions; however, holding scenarios at altitudes below 6,000 feet have a stricter regulation to enhance effective management of traffic and avoid mishaps.
