Procedure Turn
The procedure turn is used to reverse course during an approach. A
procedure turn is only available from approaches in the navigation
database. Using this data, the FMS constructs the procedure turn with
an outbound leg, a turn out leg, an arc leg, and an inbound leg, as shown
in Figure 6--97. Only the outbound leg and the procedure turn (PT)
angle are adjustable.

Typical Procedure Turn
In the example shown in Figure 6--98, the ILS Runway 5 at KHOT
approach transition contains a procedure turn that begins at HOT VOR.
The procedure turn begins with an outbound leg starting at the initial
approach fix (IAF) HOSSY.
