Mode S at TC
When, from outside controlled airspace, I call up Luton, Essex or Gatwick for crossing or ATSOCA, do you see the Mode S flight ID (in my case the registration) idependently of the Mode A code?
If so, are you permitted to identify me on Mode S alone? In which case, is the discrete Mode A code just for the benefit of other units?

The TC radar displays do not yet have the facility to interrogate the airframe id/aircraft registration database to match up that Mode S parameter and display the a/c reg from the database.
All it can do is code/callsign convert mode A codes from known flightplans or other codes that are manually input into the system.
So for now discrete mode A codes are still required, unfortunately. I get the feeling that the facility is not going to appear in the near future, neither.

Enhanced Mode S transmits the callsign as well, no idea if it is used for flightplan correlation though at your unit. Basic Mode S is another thing though, you'd have to have access to the mode s / registration database to use mode s for identifying purposes then.

What about airfield radars? Won't they all need to be Mode S capable before the TMA they're associated with/below can become mandatory Mode S for IFRs? I'm thinking Hawarden, Liverpool, Woodford, Warton, Blackpool.

As for being identified on Mode S parameters alone, currently there seems to be a big hole in MATS 1 on that one. Sure, you can be identified by various means, but I'm not sure if you can be validated if you're a free-caller.
For starters you'd presumably still be squawking mode A 7000
