5.5.11 EMI/RFI Check
After installing the GMX 200 and verifying that all interfaces to external equipment are working
correctly, a brief EMI/RFI check must be conducted. This check will verify that the GMX 200 does not
produce unacceptable interference in other avionics systems, and other avionics systems do not produce
unacceptable interference in the GMX 200.
1.
Start the aircraft engines and switch to aircraft power. Turn on all avionics except the GMX 200.
2.
With the GMX 200 switched off, verify that all existing avionics systems are functioning properly.
3.
Turn the GMX 200 on and remove power from all other avionics systems.
NOTE
Removing power from systems interfaced to the GMX 200 will cause the
associated system flags on the GMX 200 to be displayed. This is normal
behavior and does not constitute a test failure.
4.
Apply power to the other avionics systems one at a time and verify that the system is functioning
properly without any unacceptable interference caused by the GMX 200. Ensure that there is no
unacceptable interference in the GMX 200 when the avionic system is powered up. Wait for the
system to begin functioning normally before applying power to the next system.
