EMC Checkout

An EMC check should be performed after the AV-30-E 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-E. The testing
assumes the AV-30-E 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-E.
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-E 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-E 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-E continues to operate
properly.
Verify each radio operates without interference from the AV-30-E.
