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.
