If the external GPS/NAV device is configured with this behavior enabled, one
important detail is that such devices ALWAYS control whether its GPS or NAV radio
is providing guidance. Thus, when configured for auto-switching, you must use that
navigators’ CDI or NAV/GPS toggle to change whether NAV or GPS guidance is
shown on SkyView HDX’s HSI. SkyView HDX’s own HSI SRC button can only see
EITHER the GPS or NAV side of the navigator at any time.
4.5 Autopilot Operation Check
To test the Autopilot functionality on the ground, such as during a pre-flight inspection, do the
following:
Pitch and Roll Axis Operation Check
With master switch and Autopilot servo power switches ON:
1. Center flight control yoke, and lightly hold in place.
The weight of an unbalanced elevator may cause the servo to slip. Lightly hold the
controls in the centered position when operating the autopilot on the ground to offset
this effect.
2. Align HDG/TRK bug with current heading.
3. Select ALT and HDG.
4. Engage Autopilot.
5. Set Vertical Speed +1000.
6. Set Altitude 1000 feet above current. Feel yoke move in "Nose Up" direction.
7. Press and hold ALT button to return altitude bug to current. Feel yoke move to neutral.
8. Change HDG/TRK bug to right of current heading. Feel yoke move in "Right Roll"
direction.
9. Change HDG/TRK bug to left of current heading. Feel yoke move in "Left Roll" direction.
Yaw Axis Operation Check
With master switch and Autopilot servo power switches ON:
1. Move rudder pedals left and right to feel operation.
2. Center rudder pedals, and lightly hold in place.
3. Engage Yaw Damper.
4. Move rudder pedals to the left. Rudder pedals should encounter some resistance to
movement; the servo may slip.
5. Move rudder pedals to the right. Rudder pedals should encounter some resistance to
movement; the servo may slip.
6. Disconnect Yaw Damper.
7. Move rudder pedals left and right to feel operation. Resistance should not occur.
