first calls to approach
is the QNH required on first call to approach? is this requested on the ATIS?
It seems like a waste of time. If the crew gets it right it still wastes a couple of seconds. However if they get it wrong, I've got to go back in and correct them. But they're at a flight level, when they descend to an altitude, I'll give them the latest QNH then. Why do they have to tell me it on first call?
If they spent a bit more time getting their aircraft type correct, rather than just saying an 'airbus' or 'a 400', I'd be a lot happier too.
