Direct-To OBS Pressing the DIRECT-TO key twice starts the OBS
desired track editor. OBS Desired Track allows entry
of a desired track to or from the current TO waypoint.
The current desired track in the navigation pages will
be replaced by the OBS Desired Track value entered.
You may also select the reference waypoint from your
active flight plan. Waypoint sequencing is normally
set as manual. When an approach is enabled, you may
select either manual or automatic. You may wish to
select manual sequencing so you may disable
sequencing if you will be in a holding pattern that
will cause you to continually cross the TO waypoint.
When your GX is configured to receive information
from the SL30 Nav/Comm, the OBS Desired Track
field is coupled to your HSI/CDI. Your HSI/CDI is
being read by the SL30 at the same time. Rotating the
control on your HSI/CDI will update the OBS
Desired Track on your Apollo GX. You can override
the HSI/CDI input to your Apollo GX by using the
concentric knobs of the GX as described below.

frequent sequencing and waypoint alerts.
