The initial call, well according to my MATS you're required to pass callsign, type, passing level, cleared level and SID/STAR. That's not really huge is it? If you don't we only have to keep coming back to you again & again until we get the info. It saves us alot of RT time if done correctly.
Mode C checks, seems unnecessary? Couldn't agree more, complete waste of time in IMHO but what regulator demands we must do.
As for on the ground, it is split in two during busy periods, a movements planner & controller. This will become a 24 hour thing as we get more bums on seats in the tower.
New digital ATIS is being installed as we speak but again the regulator raises his ugly head and we have to do what he commands.
Ferris - is there any reason that Dubai is the only place in the world that I know of where the Approach guy doesn't control his/her own hold? Is it just politics?
Hope I answered most things
