Sorry, I am unable to access ICAO 7192-d3 so cannot to comment. I agree that a common standard is required for operations personnel who should be qualified to carry out a job that does have a flight safety and economic implication.
I will accept the idea of joint responsibility when a device is invented that will teleport me to the flight deck in question at the right moment for our three way debate, until then I will rely upon the experience of management pilots with the thousands of flying hours to support the decision making process.
Thanks for letting me know that an FAA dispatcher has spoken at length about the Vienna incident, I suppose he was here,wasnt he on that particular day taking notes....
