The flight level thing seems to have been cleared up, but it's still unclear as to whether mentioning the next waypoint is required. If on a heading, it's clear you do mention that but, must you mention the next point?? I always do, but have also have colleagues say it's not necesary - only to not mention it and then have the ATCO ask to which point we are going to. I can understand not mentioning it if one is on ones flightplan route but if going to a distant waypoint, skipping several of the flight plan waypoints, it would seem sensible to say where one is going to.
However, can anyone provide an ICAO/JAA reference that would categorically answer the question?
