Does anyone have a guidance document like CAP 413 on what should be said to HF radio operators on initial check etc.
There’s a bit of guidance in the NAT Doc 007. Position reports etc.
I was flying the other day, a couple of carriers checked in with Gander Radio and threw a few buzzwords at the operator, CPDLC, Shanwick next, request frequencies etc. On both occasions the operator came back quite annoyed requesting call sign only. That’s fair enough, but where’s this written? I’ve asked colleagues and most aren’t clear on it either and I can’t find any references on the net.
