Direct-To OBS

Navigation Basics

Pressing the DIRECT-TOkey 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.

1.Press DIRECT-TOtwice. The first character of the Desired Track value will flash. Turn the SMALL knob to change the value.

2.Turn the LARGE knob to move to the next character. Turn the SMALL knob to change the value. You may also select the reference waypoint from your flight plan waypoints.

3.When an approach is enabled, you may also select between manual or automatic waypoint sequencing. Setting sequencing to manual is useful in the case where a holding pattern would allow frequent sequencing and waypoint alerts.
