2. Verify that the outer, middle, and inner annunciations appear on the PFD when the corresponding
signal is applied. Marker beacon annunciations appear at the upper left corner of the altitude
indicator on the PFD (Figure 3-5). Operate the MKR MUTE key on the GMA 1347 and ensure
that the audio signal is muted.
3.6 GIA 63 Testing
The following section applies to both GIA 63 units. Any differences in testing will be noted.
3.6.1 VHF COM Interference Test
This test must be conducted outside. Use of a GPS repeater inside a hangar may result in a failed test.
This procedure assumes that the system is currently set to 25 kHz COM channel spacing. Once the signal
acquisition test from Section 3.3.1 has been completed successfully, perform the following steps:
1. On the MFD, monitor GPS signal strength bars on the 3
rd
AUX page.
2. On the PFD, ensure that the CDI is set to GPS. If it is not, press the ‘CDI’ softkey until GPS
ENR is displayed.
3. Verify that the GPS “INTEG” flag is out of view.
4. Select 121.150 MHz on the No. 1 COM transceiver.
5. Transmit for a period of 35 seconds while monitoring GPS 1 signal strength levels.
6. During the transmit period, verify that the GPS “INTEG” flag does not come into view on the
PFD and verify that GPS 1 does not lose a 3-D navigation solution on the MFD.
7. Repeat steps 5 and 6 and re-transmit while monitoring GPS 2 signal levels on the MFD.
8. Repeat steps 5 through 7 for each of the following frequencies:
• 121.175 MHz
• 121.200 MHz
• 131.250 MHz
• 131.275 MHz
• 131.300 MHz
9. Repeat steps 4 through 8 for the No. 2 COM transceiver (GIA2).
10. On the MFD, select the AUX SYSTEM SETUP page (4
th
page in AUX group).
11. Under the COM CONFIG field, change the COM channel spacing from 25 kHz to 8.33 kHz.
12. Go back to the 3
rd
AUX page.
13. Select 121.185 MHz on the No. 1 COM transceiver.
14. Transmit for a period of 35 seconds while monitoring GPS 1 signal strength levels.
15. During the transmit period, verify that the GPS “INTEG” flag does not come into view on the
PFD and verify that GPS 1 does not lose a 3-D navigation solution on the MFD.
16. Repeat steps 14 and 15 and re-transmit while monitoring GPS 2 signal levels on the MFD.
17. Repeat steps 14 through 16 for each of the following frequencies:
• 121.190 MHz
• 130.285 MHz
• 131.290 Mhz
18. Repeat steps 13 through 17 for the No. 2 COM transceiver (GIA2).
