Procedure

Turns

Approach Basics (GX50/60)

A procedure turn is a way of crossing the same waypoint more than once in order to accomplish a course reversal. First, make sure that flight plan leg sequencing is suspended. Second, after crossing the waypoint, set the correct inbound course to intercept. Finally, enable sequencing when you are established inbound.

Suspend Sequencing

When a procedure turn or course reversal is required, press OBS/HOLD to suspend sequencing. The OBS/HLD annunciator will light. In the cases shown in the diagram below, the Apollo GX will know when a course reversal is required and will automatically suspend sequencing.
