aniotherthing,
I was more than happy to work at Heathrow Airport doing aerodrome control, tower supervising, and Thames Radar and SVFR. I did not particularly want to be posted to West Drayton in 2003. The majority of Thames Radar controllers are either valid, or cross training onto other approach sectors, including Heathrow, so how do you work out what banding they should be on if there is to be a differential at TC?
