NAVCOM Page
The next page available from the GNC 300XL’s N key is the navigation commu-
nications (NAVCOM) page. The NAVCOM page provides a list of the airport frequen-
cies at your departure and arrival airports, allowing convenient selection of frequencies
you’ll need along your flight path. To scroll through the list of frequencies, rotate the
inner knob (
K) in the direction of the arrow prompts at the bottom left of the page.
The frequencies displayed for the departure and arrival airports are listed in the
order you are most likely to use them (see right), with the available frequencies dis-
played to the right of the airport identifier. If you do not have an active route with a
departure airport, the NAVCOM page will display the frequencies for the airport nearest
your departure position.
If a frequency has sector or altitude restrictions, the frequency will be followed by a
‘brg?’ indication.
To view restrictions on a frequency:
1. Press
C
twice to activate the cursor in the GPS window.
2. Rotate
O
to highlight the ‘brg?’ next to the frequency you wish to view.
3. Press
E
to begin viewing restrictions.
The NAVCOM page lists the frequencies for your
departure (or nearest) and arrival airports in the
following order:
