The next page available from the GNC 300’s NAV key is the navigation com-
munications (NAVCOM) page. The NAVCOM page provides a list of the airport
frequencies at your departure and arrival airports, allowing convenient selection of
every frequency you’ll need along your flight path. To scroll through the list of fre-
quencies, 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 left), with the available frequencies dis-
played to the right of the airport identifier. If you do not have an active direct-to or
route, the NAVCOM page will display the frequencies for the airport nearest your
present position.
