Why don't voice radio communications use FM?

I can expect others here to have at least a basic knowledge of how
such communications work.

We do. You don't. All communications are NOT air-ground. Disagree?

Speaking as someone who works for an OEM that works with the latest
cutting edge technology, Thomas is entirely correct.

Famous last words again. OEMs that work with cutting-edge technology
are particularly prone to mess up.

We haven't yet, in almost 100 years.

It might not hurt to read the reports now, before criticizing anyone
else for not doing research.

I think there was some confusion here. I wasn't saying that he never
heard ATC at all, just that the transmission confusion was due to the
heterodyne, not static or poor transmission quality.

But it wasn't. There were multiple transmissions that were
misunderstood, not just the two that were simultaneous.

So I guess you can point to the accidents caused by Windows-based glass
cockpits as well as you pointed to sources for accidents caused by AM
radios?

Not yet.

As far as I know (and hope), these cockpits don't have any trace of
Windows running in them. If they do, the situation is much more dire
than I had feared.

The problem is that the ergonomy of the systems is shifting towards a
desktop PC model, instead of an aviation model.

If there is a controller on the channel, they are.

Cutting-edge technology is relatively new in its current profusion,
and there's always a first time. Will you bet your life on it?

The difference is, I never said I'd read it. YOU did.

Show me the line where it says AM had anything to do with it.

That's not what you said before. You're back pedaling, because someone
mentioned CTAF and you realized you were wrong.
