The GPS 155XL’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 desti-
nation 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 5.
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.
