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.
