A solid understanding of the rules and types of course reversals on an approach is essential. Course reversals are part of the FAA’s guidance for IPCs. So, if you come out of proficiency training without feeling good about them, you didn’t get your money’s worth. Regardless, you should be familiar, lest you hear “unable radar vectors” in the soup when you least expect it.
There are two types of course reversal: the procedure turn (PT) and the hold-in-lieu-of-procedure-turn (HILPT). They both have the same basic definition: A maneuver prescribed when it is necessary to reverse direction to establish an aircraft on the intermediate approach segment or final approach course.
