Position Page
The navigation communications (NAVCOM) page
provides a complete list of airport frequencies at
your departure and arrival airports.
After the GNC 250XL acquires satellites and computes a position, the position page will
appear automatically, and you’ll be informed with ‘Ready for navigation’ on the message page.
The position page displays your present latitude and longitude, altitude and a reference way-
point field. The altitude and reference waypoint fields are also selectable (see Section 1 for more
information) to allow you to configure the unit to your own preferences. The default settings are:
• Altitude— Your present GPS altitude
• Present Position— Latitude and longitude displayed in degrees/minutes
• Reference Waypoint— The bearing and distance to the nearest airport
The position page is one of seven pages available under the GNC 250XL’s
