Again I guess I am backing the losing horse in this race but I am going to keep whipping anyway.
I assume that in the case of an aircraft advising they have changed their destination, and so need to change their routing in 3 waypoints time, that that is a reclearing of the aircraft. That then means that any and all restrictions/requirements that were placed on that aircraft at the unaffected, unchanged preceding 2 waypoints have to be restated or they cease to exist?
Sorry guys, I can't see how this is a better system. A requirement is so important in our line of work that the only way it should be cancelled is by specifically cancelling it. No ambiguity there, it stays until the ATCO says otherwise.
