Other Uses for Arc Assist
You can select the reference waypoint for the Arc
Assist feature and it can be used at any time, not just
during approach or terminal operations. It can also
be used for difficult operations such as conducting an
over water search. By establishing a user waypoint at
the center of such a search area and selecting that
waypoint as a DME Arc reference point, you can fly
circles about that waypoint at known distances. By
gradually increasing the arc distance each time you
pass a specific radial, you can expand the search area.
The Arc Assist feature of the Apollo GX can make
this much easier.
