PRESENT POSITION AS A WAYPOINT
A special waypoint location is reserved for storing present position
coordinates as a waypoint. The identifier for this waypoint is inserted
as “#1.” As well, the identifier may be used as a parent identifier for
an offset waypoint by adding an asterisk (“*”).
Waypoint #1 is redefined each time the HOLD Key is depressed. An
example of the application of waypoint #1 is to store the coordinates of
a point overflown to which you may wish to return. This is accom-
plished by depressing the HOLD Key directly over that desired point.
In this case these coordinates would be stored under identifier “#1”
until either the HOLD Key is depressed again, updating #1, or the
system is shut down.
NOTE: Since waypoint #1 is frequently redefined, it is not retained in
non-volatile memory and the identifier #1 cannot be entered on a
stored flight plan. However, the coordinates of WPT #1 can be
stored on a Flight Plan by making them part of a pilot entered way-
point. See page 3-127 for creating pilot entered waypoints. It does,
however, use up one of the 999 available waypoints, as do #OFF, #0
and EX (external) Waypoints.
