Did my Vanguard , Trident Electrical /Instrument and Autopilot courses there in the 60s and we knew it as the Heston Training Centre, at that time there was also some parts of the Flt Attendants training course carried out there, pre inflateable escape chute and Emergency training etc plus of course the Sims .the old Nunnery was next door and was being used by International Air Radio [they did the airport charts books for the Aircrew ].
The Viking Centre was situated by the Green Man on the way to Feltham close to the airport and I may be wrong but I think it was just an Engineering school as I did my Viscount training there in the 50s [SO LONG AGO!!!] .
