Procedure
Turns
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

a course reversal is required and will automatically
suspend sequencing.
