On U.S. charts, a barbed arrow indicates the maneuvering side of the outbound course on which the procedure turn is made. Using the 45 degree procedure turn, headings are provided for course reversal. However, the point at which the turn must be commenced, and the type and rate of turn is pilot discretion.
The absence of the barbed arrow in the plan view indicates that a procedure turn is not authorized for that procedure. A maximum speed of 200 knots KIAS should be observed when turning outbound over the IAF and throughout the maneuver to ensure staying within the obstruction clearance area. Normally, the procedure turn distance is 10 NM. Descent below the procedure turn altitude begins after the aircraft is established on the inbound course.
