Aircraft EMI - susceptibility

flipster, during a 42-year career, most on-aircraft susceptibilities experienced were due to:
on-frequency emissions coupled to an avionic receiver antenna
undesired high-intensity fields coupled to wires connected to remoted sensors or part of an analog feed-back loop. The latter were often parts of flight and engine controls. Best fixes were to run the signal on the digital bus rather than analog. If analog, filter and wire shield. Twist wires from multi-phase sensors such as synchros.
