EMC Checkout

An EMC check should be performed after the AV-30-C installation is
complete. The EMC check verifies that the newly installed equipment is not
producing interference to other avionics and that the existing avionics are not
producing interference to the AV-30-C. The testing assumes the AV-30-C
operational check has been completed and that the installed avionics to be
tested are all in working condition.
1. Power on all avionics except the AV-30-C.
2. Verify all existing avionics are functioning properly. Some systems may require
startup messages to be acknowledged/cleared to verify proper function.
3. After confirming all existing avionics are functioning properly, power off all existing
equipment.
4. Power on the AV-30-C and perform the following tests as they apply to the existing
aircraft equipment.
5. Observe load shedding procedures as appropriate for the aircraft during testing to
ensure adequate power to complete the testing while maintaining enough reserve
to support pre-flight and engine start.
Verify AV-30-C operates without interference from the VHF COM operation.
1. Power on the VHF COM radio.
2. Transmit on a low, medium, and high frequency. Unused frequencies are
recommended for this test. Example frequencies: 118.0, 126.0, and 135.0 Mhz.
3. During each transmission verify the AV-30-C continues to operate properly.
Verify each radio operates without interference from the AV-30-C.
1. Monitor a local frequency and verify there are no unintended squelch breaks or
other tones that would interfere with communications.
2. Monitor a remote (distant) frequency and verify there are no unintended squelch
breaks or other tones that would interfere with communications.
