According to Michael D. Dobson ed., (2001), Wings over Thurleigh,
ISBN 0-9541594-0-3 Chapter 8, Leader cable was installed at RAF airfields Scampton, Wittering, Finningley, Gaydon, Cottesmore, Wyton, Waddington, Conningsby, Benson & Honington. On the Vulcan, some time ago I found this in a post by Paddy Grogan:
"Some years following my retirement from the RAF I visited Greenham for an airshow and was permitted to go into the cockpit of a 50Sqdn Vulcan. When I began to touch the auto land switches etc My Flt Lt Pilot guide astounded me by saying " We dont know what they are for" They had never been used by him or anyone else on the squadron."
It seems that when submarines took over the strategic defence role, automatic landing ceased to be a requirement for the V-bombers. I suppose it is Secret as to whether the RAF uses automatic landing now.
