TFM-550 Installation & Operating Instructions
TiL 99RE262 Rev A Issue 9
A-2
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. For example, it is
permissible for a VFR certified GPS to lose navigation capability while the TFM-550 unit is
transmitting, providing that it recovers properly and promptly. It is not permissible for an
IFR Approach certified GPS to be affected in the same way. A complete discussion of all the
standards of airworthiness to be applied in assessing EMI effects is beyond the scope of
this document.
PROCEDURE
A.
Operate the TFM-550 transmitter on the following frequency for at least 20 seconds.
