VHF/AM RADIO FSG 2T
3 Installation
28 FAV_D10048 June 2014
Pre-wired cable harness assemblies are color coded for simple plug-in installations
when used with optional loudspeaker / junction boxes and dynamic microphones for
all kind of aircraft.
Electronic variometers seldom comply with airborne RF environmental type approval
requirements. All of the known models at printing time of this manual have to our
knowledge a (some even far) too high radiated RF interference emission. In FSG 2T
Transmit Mode, the operator may even be faced with radio energy based functional
variometer influence. Slight improvement may be achieved when the variometer
wiring is both shielded and routed not in parallel but distant to the radio wiring.
Eventually, short but bulky grounding contacts between all radio and variometer
cases may improve this E-variometer RF susceptibility capability. Further measures
to improve RF immunity may be obtained from the variometer manufacturer and in
some cases also from the aircraft manufacturer.
