In addition to the destination field and graphical CDI, the GNC 300 CDI page fea-
tures four selectable fields for various navigation data so that the page may be config-
ured to your own preferences (see Section 1 for more information). The default set-
tings for the CDI page are:
• Ground Speed (gs)— Your present speed over the ground in knots
• Distance (dis)— The distance to your destination in nautical miles
• Track (trk)— Your present course over the ground
• Estimated Time Enroute (ete)— The time to your destination based
upon your present speed and course in hours and minutes
The next page available under the GNC 300’s NAV key is the navigation commu-
nications (NAVCOM) page. It provides you with a complete list of airport frequen-
cies at your departure and arrival airports, allowing convenient selection of every fre-
quency you’ll need along your flight path. If you do not have an active direct-to desti-
nation, the navigation communications page will display the frequencies for the airport
nearest your present position.
To view the NAVCOM page from the CDI page, rotate
O
one stop to the right.
The NAVCOM page lists your departure and arrival airports on the left side of the
page, with all the database frequencies listed in a column down the right side of the
page. To scroll through the list of frequencies, simply rotate the inner knob (
K
) in the
direction of the arrow prompts at the bottom left of the page.
To place a frequency from the list in the standby field:
1. Press the
C
key twice to activate the cursor in the GPS window.
2. Use the
O
knob to select the desired frequency. Press
E
to place the frequency in the
standby field. The cursor will automatically advance to the next frequency on the list.
