SECTION 3: DIRECT-TO
NAVIGATION
3.1 OVERVIEW
The GPS 400’s direct-to function provides a quick
method of setting a course to a destination waypoint. Once
a direct-to is activated, the GPS 400 establishes a point-to-
point course line (great circle) from the present position to
the selected direct-to destination. Navigation data on the
various NAV pages provides steering guidance until the
direct-to is cancelled or replaced by a new destination.
Selecting a direct-to destination:
1) Press the
Direct-to
Key. The Select Direct-to
Waypoint Page appears (Figure 3-1), with the
waypoint identifier field highlighted.

2) Use the small and large
right
knobs to
enter the identifier of the desired destination
waypoint (Figure 3-2).

3) Press the
ENT
Key to confirm the selected
waypoint, and press the
ENT
Key again to
activate the direct-to function (Figure 3-3).
Figure 3-3 ‘Activate?’ Field Highlighted
When off course while navigating to a waypoint, the
direct-to function may also be used to re-center the CDI
(HSI) needle and proceed to the same waypoint.
Re-centering the CDI (HSI) needle to the
same destination waypoint:
Press the
Direct-to
Key, followed by the
ENT
Key twice.
NOTE: When navigating an approach with the
missed approach point (MAP) as the current
destination, re-centering the CDI (HSI) needle
with the
Direct-to
Key cancels the approach.
