PT in the days of RNAV
Simple in principle, procedure turns can turn ugly if the pilot and the controller arenít on the same page. GPS has made this worse, not better. But thatís easily remedied.
It used to be the procedure turn (PT) was the lynchpin of many an instrument approach. Youíd track to the VOR or NDB station located on the airport, fly outbound, use a PT to reverse course, and fly back to the station on a specific course while descending to the specified minimum descent altitude. If you didnít visually acquire the airport, locating the missed approach point was a simple matter of identifying station passage.
