Sound like we need Main Mode back. Is it a problem with the SSR head at Claxby? If so, get the thing changed.
I understand that the 'Radar Upgrade Programme' has ground to a halt? I think that Mode S is going into TC in 2005. No other info.
Except that the one area where 'management' must not cut corners is the NATS radar system. Taking 5 on vertically separated traffic is ridiculous!
