APPENDIX TO INSTALLATION INSTRUCTIONS POST INSTALLATION EMI TEST
2.7.1
PURPOSE
The purpose of this test is to identify any interference that the RC-9100 remote control head may
cause with existing aircraft systems.
2.7.2
TEST CONDITIONS
The RC-9100 should be installed and function tested. The TDFM-9100 transceiver should be on
throughout this test.
2.7.3
METHODOLOGY
Most of the EMI tests can be accomplished on the ground.
The GPS should be operational and navigating with at least the minimum compliment of
satellites. The VHF comm should have the squelch open. VOR/DME receivers should be selected
for display. If possible, set up a DME/Transponder ramp test set and adjust the output until the
flags are out of view. The transponder and encoder should be monitored with ramp test
equipment. Set the output of the transponder test set to 3 dB above the output necessary to
achieve 90% reply. If possible, set the ADF to a nearby navigation station.
Switch the RC-9100 on and off as often as required.
Observe the GPS for any degradation in satellite status or availability or flags. Listen for any
noise or detected audio signals on the VHF comm(s). Listen for any noise or detected audio
signals on the VOR/LOC receiver audio; look for any movement of flags or needles on the
VOR/LOC/GS navigation display(s).
List the power plant, fuel, and other electric instruments not already in the chart provided and
note any anomalies that occur due to operation of the RC-9100. Assess the results.
If the aircraft is equipped with an autopilot or a stability augmentation system, then test fly the
aircraft and verify that operation of the RC-9100 does not have adverse effects on these systems.
After checking for gross effects at a safe altitude, fly a coupled ILS approach and look for any
anomalies.
2.7.4
RESULTS
If the installed system passes all of the applicable EMI tests, then no further action is required. If
interference is observed, then the interference must be assessed against the appropriate
standards of airworthiness for the system in question. A complete discussion of all the standards
of airworthiness to be applied in assessing EMI effects is beyond the scope of this document.
