What are the circling minima for an aircraft flying at speeds between 141 and 165 KTS?

For an aircraft flying at speeds between 141 and 165 knots, the appropriate circling minima is indeed 2.3 nautical miles (NM). This decision is based on regulatory standards and safety considerations outlined in Instrument Approach Procedures.

The circling approach is designed to enable pilots to maneuver the aircraft to a landing runway while ensuring adequate safety margins. The required visibility and distance criteria account for the increased rate of descent and maneuvering capability of faster aircraft. For this specific speed range, a larger radius is necessary to safely conduct the circling maneuver, which is why 2.3 NM is specified.

This extra distance ensures that pilots have sufficient space to complete turns while maintaining visual contact with the runway environment, ultimately enhancing safety during landings in visually challenging conditions.
