Not all approaches in the database are approved for
GPS use. As you select an approach, a “GPS” designa-
tion to the right of the procedure name indicates the
procedure can be flown using the GPS receiver. Some
procedures do not have this designation, meaning that
the GPS receiver may be used for supplemental naviga-
tion guidance only. ILS approaches, for example, must
beownbytuningtheVLOCreceivertotheproper
frequencyandcouplingtheVLOCreceivertothe
externalCDI(orHSI).
Once an approach is selected, it may be activated
for navigation from the Procedures Page. Activating the
approach overrides the “en route” portion of the active
flight plan, proceeding directly to the “approach”
portion (for a full approach, directly to the initial
approach fix).
To activate an approach (which was previously
loaded):
When an approach is “Loaded”, it is added
to the end of the active flight plan. Prior to
reaching the approach course, select “Acti-
vate Approach?” to begin navigation along
the approach course.
1. Press the PROC key to display the Procedures
Page.
2. Turn the large right knob to highlight “Acti-
vate Approach?” and press ENT.
Another Procedures Page option allows you to
activate the final course segment of the approach. This
option assumes you will receive vectors to the final
approach course and guides you to intercept the final
course, before reaching the FAF.
To activate the (previously loaded) approach, with
vectors to final:
With the full approach “Loaded”, select
“Activate Vectors-To-Final?” to provide
navigation guidance along the final approach
course segment only.
1. Press the PROC key to display the Procedures
Page.
2. Turn the large right knob to highlight “Acti-
vate Vectors-To-Final?” and press ENT.
In many cases, it may be easiest to “Load” the full
approach while still some distance away, en route to
the destination airport. Later, if vectored to final, use
thestepsabovetoselect“ActivateVectors-To-Final”
— which makes the inbound course to the FAF
waypoint active. Otherwise, activate the full approach
using the “Activate Approach?” option.
If you reactivate the approach currently being
flown using the PROC key, prior to reaching the MAP
a Restart Approach confirmation window appears on
the screen. If you have passed the MAP, the 500W-
series unit proceeds to the transition waypoint without
a restart confirmation.
