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).

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.
