I thought that went out many years ago?
We had it at Farnborough when we operated from the Mk3 control tower with Plessey Watchman consoles until late 2002, then we moved to the Mk 4 tower and switched to TFT screens and lost the facility.
It's called 'progress'. I believe Farnborugh 'ditched' DF completely about 3 years ago.
