If the CR62 was set up correctly, a controller could 'learn' to operate the servos so that a talkdown to touchdown was entrely possible. By this I mean you 'moved' the scan of the two radar beams to follow the aircraft, and adjusted gain at the same time to keep the blip as small as possible.
If you've ever seem the Discovery Wings programme about the Challenger 604 bizjet, you'll know what I mean. As far as I know, RAF airfields were only authorised to do this in emergency; my unit was authorised to do it any time.
