Sorry to keep barking up this tree but the ommission of "Flight Level" or "Altitude" in both clearences & readbacks is now of epidemic proportions. I fly out of Italy & am P*** off with having to constantly ask my #2 to include this in his readbacks. No help when the en-route controllers do same- Ok, we are above 10,000 so no ambiguity but how about this one-"AB123 descend 270, heading 310 speed 290" Gee, was that descend FL310,
heading 290 degrees,speed 270 kts.All cool stuff but a tired crew on a dark & dirty night does not need this level of ambiguity.
