Note the magenta line in the bottom figure, 
which represents the currently active leg of 
the approach. The distance (DIS) displayed on 
the above screens is TO the “D13.0” point. The 
flight plan will automatically sequence to the 
next leg upon reaching “D13.0”. 
3.   At 13.0 NM from the IAF, a waypoint alert 
(“DTK 265° x S”) will appear in the lower right 
corner of the screen. Make a standard rate turn

2.   Note that within a few seconds of pressing 
OBS to release suspend mode and start the 
approach sequence, “SUSP” re-appears above 
the OBS key as the 400W-series unit returns 
to suspend mode. This is normal when flying 
a course from fix to altitude leg and indicates 
that automatic leg sequencing is suspended. 
  NOTE:  If there is a valid baro-corrected pressure 
altitude input, the SUSP is not...

approach holding point), an alert message 
in the lower right hand corner of the screen 
will recommend the holding pattern entry 
procedure (“HOLD  PARALLEL”). As you fly the 
holding pattern, a timer appears on the default 
NAV page. The timer automatically resets on 
each outbound and inbound portion of the 
holding pattern.

runway (RW02, in this example) and transition 
(GEDIC). 
2.   As you depart the airfield, “NEXT DTK 026°” 
appears in the lower right corner of the screen 
and “SUSP” appears directly above the OBS 
key. You are now on the “course from fix to 
manual sequence” leg. The distance displayed 
on the active flight plan, default NAV and map 
pages is FROM the waypoint fix (the departure 
runway,...

The automatic switch from GPS to VLOC is not 
immediate, but instead occurs gradually to prevent 
abrupt CDI changes when coupled to an autopilot. 
The CDI selection can also be changed manually by 
pressing the CDI key. Once the switch from GPS to 
VLOC has occurred, either automatically or manu-
ally, it will not automatically switch again until the 
approach is reactivated or another approach is 
selected. To prevent automatic ILS CDI selection, 
choose the “Manual” ILS CDI...

 NOTE: From this point on, primary navigation is 
provided by the VLOC receiver. You may continue 
to use the GPS receiver for supplemental naviga-

disabled (“Manual” selected), the reminder mes-
sage “Select VLOC on CDI for approach” appears
