Instruction Manual

To change any of the selectable fields on the CDI page:
1. Press C twice to activate the cursor in the GPS window.
2. Rotate O to highlight the field you would like to change.
3. Rotate K to change the field to display the desired information.
4. Rotate O to highlight another field, or C to finish.
The GNC 300XL’s course select feature allows the pilot to define the inbound
course to, or outbound course from, the ‘active’ waypoint, using an external HSI.
Once the course select function is activated, the selected course will be displayed
next to the destination waypoint identifier and the CDI will provide guidance relative
to the desired course. The course select feature is only available during route,
approach or direct-to navigation. For more information on the course select feature
and the GPS SEQ switch, see Section 6.
To set a desired inbound course:
1. Dial the desired course on the HSI.
2. Set the external GPS SEQ switch to the HOLD position.
3. To stop the course select function, set the GPS SEQ switch back to the AUTO position.
