A procedure turn is the maneuver indicated when it is necessary to reverse direction to establish the aircraft inbound on an intermediate or final approach course. The procedure turn or holding in lieu of a procedure turn is a required maneuver, unless cleared for a straight-in approach by ATC. The procedure turn is not required when the symbol “NoPT” is depicted on the initial segment being used, when radar vectors are provided to the final approach course, when conducting a timed approach, or when the procedure turn is not authorized.
Course reversals are depicted in one of three ways: 45/180 degree procedure, a holding pattern, or a teardrop procedure. Components of the procedure are depicted in the plan and profile views. The maneuver must be completed within the distance and at the minimum altitude specified in the profile view.
