Communications on published ‘airband’ VHF AM frequencies are ‘private’? Doesn’t make sense to me. When I broadcast on Area or CTAF, I’m kinda hoping people - number and identity unknown - will be listening and I don’t particularly care if that includes Cyril the plane spotter who’s recording what’s going on.
I recall there is something somewhere, in some training syllabus, about the security of aviation comms. I’m yet to see the current rule that deals with the issue and, if it exists, we can be certain it’s not enforced.
