DME Arcs
(Arc Assist)
DME-Arcs are usually used as a method for pilots to
intercept a flight plan leg, or a course to a fix. They
are sometimes used as a method for reaching a
subsequent fix such as a missed approach holding
waypoint.
The Apollo GX automates your DME-Arc procedure.
As you near the start of the DME-Arc rather than a
typical arrival alert, you are prompted that the next leg
is a DME-Arc and that you may use Arc Assist. Using
Arc Assist is optional. Pressing
ENTER will take you
to the ARC reference point page. Verify that the
reference waypoint is correct.
The CDI and map display can be used for guidance
along the DME-Arc. You may also use the Arc Assist
page for guidance to fly the arc.
1. When you receive notice of the next leg or your
flight plan is a DME-Arc, press
ENTER.
2. Verify the Reference waypoint is correct (if the
reference is changed, the approach will be
unloaded). Press
ENTER.
