En-Route Airway Handover R/T
Other threads have discussed a similar topic before, but my question to ATC is:
What is the minimum r/t you require for check-in to an en-route controller?
I think I already understand requirements for departure, arrival etc because they are nicely covered in CAP413 in the UK. But en-route handovers are not covered.
I fly in Europe, and use ATC callsign, A/c callsign, assigned level, next waypoint (or assigned heading). A colleague recently suggested that the next waypoint is not required.
I am expecting at least three different answers here (UK, USA, ICAO ...). Any references would be appreciated.
Thanks in advance.
