Default Why don't voice radio communications use FM?

Yeah, I'm very serious... In fact, it cuts down on the wiring...


Which means that a single break in a single wire disables multiple
aircraft systems. Brilliant.

Think of
multiple control stations aboard an aircraft being able to control various
pieces of hardware... With the typical analog controls like you have for
lights in your house, you would be running 110VAC all over everywhere...


I could never find a justification for those home remote control
systems that used house wiring, and they weren't always reliable,
anyway.

Well, that's because FM doesn't provide any real benefit as compared to AM
for aircraft communications... As I've shown in the above aircraft, using
TCP/IP for communication / control of various devices aboard an aircraft can
definitely provide a certain benefit...


It makes things cheaper, I suppose. I'm not sure I see a safety
benefit, and there might even be a reduction in safety.
