Perhaps this is a naive question, but: Why don't voice radio
communications for aviation use FM radio instead of AM radio?

I understand it is because of a characteristic of FM called "capture
effect" that blanks out weaker transmissions when two radios transmit at
the same time. The listener would have no idea that a second, weaker
transmission was being made.

No actually, it's just historical. Early av radio used AM, and for that
reason we still do.
