The next page available from the GPS 155XL’s
N
key is the navigation communi-
cations (NAVCOM) page. The NAVCOM page provides a list of the airport frequencies
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 left), with the available frequencies
displayed 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
to activate the cursor.
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:
