Confirm your passing...
PGA, I agree with your last. You do have to think twice on wheather you've been cleared higher or not. It just adds a wee bit of uncertainty to your climb. I think below the TL ATC should use "Confirm your passing Altitude" as some already do.
Actually thinking about it more, there doesn't seem to be any consistency as to when the two are used? Can ATCOJ30 shed any light?
Perhaps there's a good reason behind it and I as a jockey have forgotten some important stuff I really shouldn't have..
Cheers Crew..
