ATNB1 - CPDLC
Hi, I'm teaching the aircraft side of this at a sim center but would be grateful for an ATC perspective about radio procedures, the GOLD isn't very useful.
Specifically, if you are transiting through different airspace are frequency changes given on the RT with a RT required check-in or is it all via datalink and "monitor" next frequency. One would have thought if immediate ATC RT contact is required then a check in to make sure the radio is working would be in order!
Thanks very much!
