A few of the folk who do Heathrow approach consider themselves to be elite and make it known but they are usually the ones who create a 10 minute delay every time they plug in.
There are positions in the room other than Heathrow. Most of the positions are TMA sectors (North, South, Midlands, East and Capital) and the rest consist of the approach functions for Gatwick, Stansted/Luton (Essex Radar) and London City (Thames Radar).
Trainees get posted to all positions in the room straight from the college and some controllers cross validate to other sectors in the room.
I work a TMA sector and whilst I don't consider myself to be elite compared to my colleagues elsewhere, I do know that the airspace I control is much busier and much more complex than a lot, if not most other places. Obviously there are some people who will disagree with that statement, after all everyone is a better controller than everyone else
You have to be careful when discussing this as it will no doubt touch on a few sore spots. There is nothing "elite" at all about the controllers posted to TC. They may be siginificantly better at controlling a low level TMA or approach sector than someone who does a high level "hello, goodbye" but on the flip side they might be totally useless at controlling that high level sector or even an aerodrome for example.
What the figures do show though is that TC is generally a more difficult unit to validate at than elsewhere - at least on the TMA/Area side of things.
Some controllers are better than others. There are controllers out there who never cease to amaze me with their skill and professionalism. There are also controllers out there who make me wonder how on earth they still have a licence. The unit to which the controller belongs has no bearing on which of the above categories they fall into though. I know for a fact that not all TC controllers are elite gods because some of them are in fact quite sh!t.
