5.3.8 Pitot Static System Leak Check
Perform a pitot static system leak check in accordance with the aircraft manufacturer's approved data.
CAUTION
To avoid damaging the G5 pressure sensors, both the pitot and static ports must be connected to
the air data test set.
5.3.9 Altimeter System Test
For aircraft that are IFR certified, perform an altimeter system test of the G5 in accordance with 14 CFR
Part 43 Appendix E.
5.3.10 GPS Receiver COM Interference Test
This test must be conducted outside, as the use of a GPS repeater inside a hangar may result in a failed
test.
1. Enter configuration mode on the G5 and navigate to the GPS Configuration Page.
2. Ensure a valid GPS position fix is obtained by monitoring the GPS status. The following status
indications are valid fixes for this test.
•
3D GPS
•
3D DIFFERENTIAL
3. Select 121.150 MHz on the COM transceiver.
4. Transmit for a period of 30 seconds while monitoring the GPS status.
5. During the transmit period, verify that the GPS status does not lose a valid GPS position fix.
6. Repeat steps 2 through 4 for the following frequencies:
•
121.175 MHz
•
121.200 MHz
•
131.250 MHz
•
131.275 MHz
•
131.300 MHz
7. Repeat steps 2 through 5 for all other installed COM transceivers (if applicable).
8. If an installed COM supports 8.33 MHz channel spacing, increase the transmit period to 35
seconds and repeat steps 3 through 5 for the following frequencies:
•
121.185 MHz
•
121.190 MHz
•
130.285 MHz
•
131.290 MHz
9. Repeat step 7 for all other installed COM transceivers supporting 8.33 MHz channel spacing (if
