    TDFM-136B Installation Instructions 3.2 Appendix B - POST INSTALLATION EMI TEST INSTRUCTIONS 3.2.1 PURPOSE The purpose of these tests is to identify any interference that the TDFM-136B may cause with existing aircraft systems. 3.2.2 TEST CONDITIONS The TDFM-136B transceiver should be installed and function tested. The antenna VSWR should be checked.

  • Page 22: Results

    If the interference is not rectified, the unit shall be placarded to avoid use during the appropriate phase of flight. For example, if the unit causes undesired operation of the ILS, then the TDFM-136B should be placarded, “Not to be used during an IFR ILS approach.” Technisonic Industries Ltd.

  • Page 24 Determine if the image frequency for the VHF Comm falls within the range of the TDFM-136B. If so, select a set of frequencies that will cause the TDFM-136B to be set as close as possible to the image frequency. Any one of the many possible sets will suffice. Record those values in the spaces provided in the following chart.
  • Page 25 Determine if the image frequency for the VOR/ILS Nav falls within the range of the TDFM- 136B. If so, select two sets of frequencies that will cause the TDFM-136B to be set as close as possible to the image frequency. Choose one set in the localizer frequency range and one in the VOR frequency range.
