Creating Reference Waypoints
The GNC 420 allows the pilot to create a new user
waypoint at a defined radial and distance from the present
position. To reference the present position, follow the
preceding steps, but press the CLR Key in Step 4. ‘P.POS’
appears in the reference waypoint (REF WPT) eld to
indicate that radial and distance information references
the present position. The second reference waypoint field
(REF WPT) is a temporary reference only, not a reference
that is stored with the user waypoint. By default, this
eld displays a radial from the nearest VOR. However,
the pilot can select any waypoint by identifier to use as a
reference in this field.
The GNC 420 can store user-defined waypoints
which are generated from other equipment
in the panel. For example, an EFIS equipped
with joystick inputs can be used to create user
waypoints which (if the installation supports this)
automatically transfer to the GNC 420.
Creating User Waypoints from the Map Page
The Map Page and panning target pointer (Section 3.4,
Map Panning) provide a quick means of saving the present
position as a user-defined waypoint.
Capturing and saving the present position
as a user waypoint:
1) With the Map Page displayed, press the small
right knob to activate the panning function.
The target pointer appears at the present
position (Figure 7-40).
