Page 2-11

Proceed with suppression work as described in a) above until no further interference is detected.

2.

Static inverters, choppers, DC converters :

For interference suppression inserting a filter into the positive power supply lead close to the
item concerned is suggested, in order to isolate the harmonics of the chopper frequency from
the aircraft wiring system.

3.

RF interference :

Interference resulting from the operation of transponder, DME or communications equipment
may occur if the associated antenna has poor ground contact and the screen for the antenna
connecting lead is causing radiation.

It is mandatory to proceed in accordance with FAA requirements!
