Standard 45° Procedure Turn

The standard 45° procedure turn is one of many course reversal maneuvers, used when approach procedures do not permit straight-in approaches unless radar vectored.

Steps: 

1. Start timing at A for 2 minutes from A to B. [see figure here]
2. At B, turn 45° (standard rate). After roll-out, fly 1 minute to C.
3. At C, turn 180°.
4. At completion of turn, time 45 seconds from D to E.
5. Start turn at E for 45° change of heading to reciprocal of heading at beginning of maneuver.
