OK Hempy... know what you are saying...but it was much more deliberate than that.
Not it was not exactly :-
" OK you guys wake up I'm going to give you a clearance which has around eight items in it....all of which will be identical to what you expect....but one will be slightly different. If you just hear what you thought you were going to here you will have a Gross Nav error and rather like the Cathy skipper will be fired"
Reason I ask is that on the return leg we had a change to alt....but no heads up that the clearance was going to be changed.
I assumed there would be an SOP phrase for this to prefix an ammeded clearance?
