Navigation Communications Page
The CDI page with active destination.
After the GNC 250 acquires satellites and computes a position, the position page will appear
automatically, and you’ll be informed with a ‘Ready for navigation’ message 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 six pages available under the GNC 250’s NAV key:
• CDI page • NAVCOM page
• Position page • Satellite status page
• NAV menu 1 • NAV menu 2
During most flights, the position, CDI (course deviation indicator) and NAVCOM pages will be
the primary pages used for navigation. The pages available under each key are accessible by press-
ing the desired key and rotating the outer knob, or by pressing the NAV key repeatedly.
