HDG Mode Operation – Heading Bug Steering
1. Set the PFD Heading Bug to the desired heading (Section 4.4.9).
2. Verify that GPSS is not selected.
3. Select the autopilot’s Heading (HDG) mode.
4. Engage the autopilot and verify that the autopilot turns the aircraft to the
selected heading.
HDG Mode Operation – GPS Steering (GPSS)
1. Couple the PFD CDI to a GPS navigation source with an active ight plan.
2. Enable GPSS by pressing the GPSS Hot Key.
3. Select the autopilot’s Heading (HDG) mode.
4. Engage the autopilot and verify that the autopilot turns the aircraft to follow
the GPS ight plan.
NAV Mode Operation – VLOC Navigation
1. Using the CDI Source Select button, couple a tuned/valid VLOC radio to the
PFD CDI and adjust the Course Pointer (CRS) to a value that will intercept the
course.
2. Set the PFD Heading Bug
3. Engage the autopilot in Heading (HDG) mode and verify that the aircraft turns
to the desired heading.
4. If your autopilot supports automatic Heading to Navigation mode transitions,
arm Navigation capture on the autopilot by selecting its Navigation (NAV)
mode. Otherwise, select the autopilot’s Navigation (NAV) mode when the
autopilot’s navigation signal capture criteria are satised (see your autopilot
AFMS for more information).
5. Monitor the PFD CDI deection and verify that, upon intercepting the desired
course, the autopilot modes transition appropriately and the autopilot tracks
the desired course.
NOTE
When GPSS is enabled, the Heading Bug is not coupled
to the autopilot. To connect the Heading Bug to the
autopilot, disable GPSS with the GPSS Hot Key.
NOTE
The autopilot must be in Heading (HDG) Mode to
receive GPSS signals from the PFD.
NOTE
When using an integrated GPS/VLOC navigator, select
VLOC or GPS with the CDI source button on the GPS
select until the desired CDI Navigation Source is shown
on the PFD (SeeSection4.4.5.)
