CREATING AN OFFSET WAYPOINT

This procedure enables the system to create a waypoint at a given
radial and distance from a known point. The known point (parent
waypoint) may be any stored personalized or database waypoint.

An offset waypoint may be inserted in any Waypoint IDENT field.
The offset waypoint is retained in memory after system shutdown
ONLY if entered on a Stored Flight Plan.

Position the cursor over the desired waypoint IDENT field.

NOTE: The offset waypoint uses station declination, if available, or it
uses the calculated magnetic variation of the parent waypoint. All
waypoints defined by a VHF Navaid in the National/International
Airspace System are based on the VHF Navaid station declination.
Since the magnetic variation and station declination may not be the
same at a given Navaid, the calculated position and the defined
FMS position may differ.

Parent Waypoint IDENT-
INSERT with an * follow-

NOTE: More than one offset
waypoint is allowed from one
parent, using *, *1, *A1, etc.,
as identifying notation.
