Norwich Radar was operational at RAF Coltishall whenever they were open, this aided the coordination between the units. This was especially necessary when Colt were on Rw04 as the approach path was directly over Norwich Airport. Indeed it is not unknown for then occasional aircraft (not Colt based) to make an approach in error to then operational RW 04 at Norwich. That is why there was a big. NOR on the threshold of RW 04 which as those of you old enough may remember had a long Sterile Area due to the Terminal being at the Southern end. The old KLM F27's used to land on Rw22 and basically coast into stand probably the shortest taxi anywhere from end of Runway to the terminal. Back at Norwich was a Marconi S511 with colour cathode ray tube displays but no SSR. There was a full sized radar approach console in the VCR which was used as an ATM when APR was at Coltishall. The Radar controller used to sit alongside the ADI ATCO and it worked brilliantly with the Situational Awareness and coordination of both controllers greatly enhanced. There was also a radar room downstairs with 2 operational radar postions but it really was shoeboxed sized and not utilised very much. When Coltishall closed in 2006 SSR data was imported from the Cromer radar. When the Tower furniture was replaced a proper radar room of decent dimensions was opened downstairs. At that point a proper ATM was fitted in the VCR and the radar postion in the VCR was closed. It is much mourned by the older controllers. That how things continued until about 3 years ago when the Marconi radar next to the tower was retired and replaced by a Thales digital search radar near the fire station on the southside of the airfield.
