A
Altitude (GPS ALT): Altitude, as calculated by the
Apollo GX, based upon a mathematical model of the
earth’s surface curvature. A substantial difference
between this altitude value and altitude referenced
to sea level may exist.

Altitude Assist: An aid that provides guidance in
descending from one altitude to another. See the
Altitude Assist description on page 14 for details.

ARC: A DME arc terminator with the preceding
flight plan leg is described as an arc to this waypoint.
An ARC waypoint may follow another ARC
waypoint.
