Javelin said US ATC is clearer, simpler...
I don't know for the rest of Europe, but In France we make things more and more complicated. When we think about a new procedure we always spend hours anticipating all kinds of technical failures...it makes ATC rules heavier to use...but perhaps more safely..?
As an exemple we cannot give a radar heading for departure, we have to give a full description of it, in case of airplane radio failure.(to join cruising level or holding pattern)...and so on...
Sure I agree we have to make it clearer and simpler....US ATC seems to be safe...even when technical problems occur...even without having spent hours thinking of them :-)
Airbuses are so lovely...(Girl technical opinion )
