I was responsible for the Form 540 on 44(R) Sqn for a while at the end of the 70s. UK training sorties were not recorded though rangers and anything unusual were. It’s a sad fact that the guys responsible for compiling these records (myself especially) had little sense of history being more preoccupied with beer and birds. The F540 was one of those much resented ‘secondary duties’ and its importance was not appreciated. Far more information might be obtained from the Squadron’s authorisation sheets – wherever they are!

The 24V socket would be for a trolleyac – trolley accumulator. The Derwent’s starter was electrical so the trolleyac was probably used for the first start of the day.

the main wheel steering assembly has broke and cant move

It’s the nosewheel that does the steering of course though the Vulcan can also be steered by differential breaking.

Have received photos of 603 doing ground run last year:
