Time and again flying in to LGW you get a clearance to descent to a certain level followed by the coment to expect XXX level by Bexil, GWC, etc. I have heard many foreign crews reply that they were descending to the expected level rather than the cleared level.
I appreciate that it must be crucial that we are at the required level by these waypoints
but I feel that this type of clearance causes extra talk time and more confusion potential.
