The waypoint sequencing field, located at the
bottom left of the direct-to confirmation page,
allows you to ‘hold’ on a selected route waypoint
and prevent the GNC 250XL from sequencing to
the next route waypoint.
If you have selected the ‘hold’ setting from the
waypoint sequencing field, your selected course
will appear at the bottom left of the CDI page and
the map page. You may change your selected
course right from this field by highlighting the
course field and rotating the inner knob. Press
E
to confirm the course.

A Course
Whenever you perform a direct-to, the GNC 250XL will set a point-to-point great
circle course to your destination. You can also manually define the course to your
destination with the GNC 250XL’s
course select
feature. The course select feature is
available from the bottom line of the
direct-to confirmation page
and works like
selecting your desired course on a VOR indicator.
To manually set a course:
1. Press the
D
key. The direct-to confirmation page will appear.
2. Rotate
O
to place the cursor on the course select field.
3. Use
K
to begin entry of the selected course (the
O
and
K
knobs may be used once
you have started editing the course select field).
4. Press
E
to accept the course, and
E
again to acknowledge the ‘ok?’ prompt.
The GNC 250XL will now use the selected course for your CDI and DTK steering
guidance. To reset the course to a GPS-calculated course from your present position,
simply press
D
, followed by
E
.
