procedure turn

[prə′sē·jər ‚tərn]
(navigation)
A constant-rate turn of an aircraft in flight; used for computing the radius of turn and time required for its execution when very accurate navigation is required in controlling time or maintaining accurate, predetermined tracks.

procedure turn

procedure turn
Procedure turn left.
A maneuver in which a turn is made away from designated track followed by a turn in the opposite direction, both turns being executed so as to permit aircraft to intercept and proceed along the reciprocal of the designated track (ICAO). A procedure turn may be made either in a level flight or while descending. Depending on the initial turn, a procedure turn may be “left” or “right.” It is the maneuver prescribed when it is necessary to perform a course reversal to establish the aircraft inbound on an intermediate or final approach course. The procedure turn, or hold in lieu of a procedure turn, is a required maneuver for pilot training currency. The procedure turn is not required when the symbol “No PT” is shown, when radar vectoring to the final approach course is provided, when conducting a timed approach, or when the procedure turn is not authorized. The hold in lieu of a procedure turn is not required when radar vectoring to the final approach course is provided or when “No PT” is shown. The altitude prescribed for the procedure turn is a minimum altitude until the aircraft is established on the inbound course. The maneuver must be completed within the distance specified in the profile view.
