Airport Approaches
NOTE: Not all approaches in the database are
approved for GPS use. As you select an approach,
a “
G
P
S
” designation to the right of the procedure
name indicates the procedure can be flown us-
ing the GPS receiver. Some procedures will not
have this designation, meaning the GPS receiver
may be used for supplemental navigation guid-
ance only. ILS approaches, for example, must be
flown by tuning the VLOC receiver to the proper
frequency and coupling the VLOC receiver to the
external CDI (or HSI).
Airport Approach Page Options
The following options are available for the airport
approach page, by pressing the MENU key:
Load into Active FPL? allows you to load the
selected approach into the active flight plan—with-
out activating it. This performs the same operation
as selecting “Load?” from the procedures page “Select

To load an approach from the airport approach
page:
1. Select the desired approach and transition
using the steps outlined in Section 5.
2. Press MENU to display the airport approach
page options.
3. Turn the large right knob to highlight “Load
into Active FPL?” and press ENT.
4. The active flight plan page will appear. Press
FPL to return to the airport procedures page.
Load and Activate? allows you to load the
selected approach into the active flight plan and
activate navigation guidance to the approach
transition.
To load and activate an approach from the airport
approach page, follow the steps above, but select
“Load and Activate?” in step #3.
Select Approach Chnl? allows you to select the
channel number for a WAAS approach for the
current destination. The channel number for the
WAAS approach is available from an approved
approach chart.
If duplicate numbers are available for a channel,
a list will be available where you may select the
desired approach.
After selecting “Select Approach Chnl?”,
choose the WAAS channel number for the
current destination.
