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