As we speak, the new traffic manager's desk is being built. This will free up 3 radar positions (the old LL, KK and SS/GW EAT suites).
Either Heathrow will move up to the end and you guys will slot in between Heathrow and TC South or you will just take the three available slots without anyone else having to move. I'm not sure which.
As of yet, I'm not sure where your big map is going to go - but you won't need that torch thing, because we have lights where we are. Maybe you could encourage NATS management to sell the torch to make a bit of money.
Also, our radars are square and show colours other than orange. Mainly blue and green but occasionally white and then red. I'm not sure how the processed data suits the SVFR / low level operation etc (neither could I give a monkey's toss).
By all means come across the road one day and have a look. Phone the TM / GS on the day, and a same-day visit can be arranged in a minute.
I will try and find out anything else you guys wish to know.
