• 121.190 MHz
• 130.285 MHz
• 131.290 Mhz
18. Repeat steps 14 through 17 for the No. 2 COM transceiver (GIA2).
19. On the MFD, select the AUX – SYSTEM SETUP page and change the COM channel spacing back to
25 kHz.
20. Continue to the VOR/LOC/GS Test.
VOR/LOC/GS Test:
Check the VOR, ILS, and Glideslope functions with ramp test equipment. Operate the equipment
according to the test equipment manufacturer’s instructions. Adjust the RF signal to a level adequate to
perform the test. Select the appropriate HSI source by using the CDI softkey.
NOTE
The PFD HSI does not show a course deviation bar unless a valid VHF NAV frequency
is tuned.
Simulate a VOR signal on radial 000° with a course-width of 20°. Verify full-scale deflection of the CDI
while applying a 10°-deviation signal. Exercise the CDI with both right and left deviations for both
NAV 1 and 2 receivers. Repeat using a Localizer signal (tune NAV 1 and NAV2 receivers to appropriate
frequency). Exercise the Glideslope deviation indicator with up and down deviation indications.
GFC 700 VOR/LOC/GS Test
NOTE
Perform this test only if the aircraft is equipped with a GFC 700.
1. Simulate a VOR signal on radial 360° with a course-width of 20°. Tune the NAV1 and NAV2
receivers to this specific frequency.
2. Set the HSI on the PFD to NAV1 by pressing the CDI soft key until NAV1 is selected. Adjust the
HSI course as necessary using the CRS knob.
3. Verify full scale deflection of the CDI while applying a 10° deviation signal. Exercise the CDI with
both right and left deviations for both NAV1 and NAV2.
4. Engage the Autopilot in altitude hold mode and press the NAV key on the MFD. Apply a right signal
deviation to the CDI. Verify that the Flight Director and aircraft controls respond and follow the
CDI. Apply a left signal deviation and verify the Flight Director and aircraft controls follow the CDI.
5. Press the CDI soft key to select the NAV 2 receiver. Verify that the NAV annunciation flashes
yellow, then returns to default PIT mode.
6. Repeat Step 4 while the NAV 2 source is selected on the HSI.
7. Simulate a Localizer/Glideslope signal. Tune this signal on NAV 1 receiver. Set the HSI to LOC1.
Use the test equipment to center the deviation bars (localizer and glideslope) on the PFD.
8. Press the APR key on the MFD. Verify that the LOC and GS annunciations are green on the PFD.
Apply right/left and up/down localizer/glideslope signals using the test equipment. Verify that the
Flight Director and flight controls respond appropriately.
9. Repeat Steps 7 and 8 for the NAV 2 receiver.
