5. Slowly adjust the course pointer on the G5 HSI CDI toward the aircraft heading until VOR
captures.
6. Center G5 HSI CDI course pointer on the aircraft heading.
7. Engage the autopilot in NAV mode.

1. Tune the VHF NAV to the NAV/COM Test Set frequency for LOC operation.
2. On the NAV ramp tester simulate centered LOC needle presentation.
3. Set the Course pointer on the G5 HSI to the current aircraft heading.
4. Verify the G5 HSI CDI displays centered deviation for LOC.
5. On the NAV ramp tester simulate 0.093 DDM Left LOC.
6. Verify G5 HSI CDI deviation bar is one dot left.
7. Verify that the flight controls turn to the left.
8. On the NAV ramp tester simulate 0.093 DDM Right LOC.

10. Verify that the flight controls turn to the right.
11. On the NAV ramp tester simulate centered LOC needle presentation.
12. Disengage the autopilot.
6.3.12.1.4 GPSS Course
This test is only performed for installations that are interfaced to a GPS navigation source and the
interfaced autopilot did not previously have a GPSS function. Conduct this test with the aircraft
positioned where it can receive GPS signal.
1. On the GPS navigator, enter a simple Direct-To flight plan with a waypoint that is on the current
aircraft heading and select the G5 HSI CDI to display GPS. If the navigator has the capability to
enter user waypoints, a user waypoint can be entered to facilitate this test. It is suggested that
the waypoint be within 5 miles of the current aircraft position for best results.
2. On the G5 Attitude display, press the multifunction knob to display the G5 attitude menu,
highlight GPSS and press the multifunction knob to select GPSS.
3. Verify the following;
