You'll have to cite a source for this nugget of knowledge.

FAA AIMs and CFRs make it pretty clear that communications involving a
controller are pilot-controller exchanges, not pilot-pilot exchanges.

While that may be true, it in no way relates to your statement quoted
above.

Stating "you're not supposed to listen to other pilots" is just plain
wrong. Pilots listen to other pilot transmissions to increase their
situational awareness.


Are you familiar with Common Traffic Advisory Frequency (CTAF)?

Yes, but it and similar schemes don't involve a controller, so
obviously the communication is between aircraft directly.

Thank you.
