Shame the Flight Directors were removed from the Sperry Aircraft when they were sent to Nigeria from the UK.
I loved the explanation...."....but who will pay for them?"
Nothing changed later on. When Bristow packed up in the USA we had an S76s back from Rhode Island and the GOM. They were fully IFR complete with DME. Redhill modded them to North Sea standard and took the DMEs out.
"They are not required in the North Sea, you have Decca." was the explanation.
Two months later the Norwegian CAA stipulated that Decca was unacceptable for precision approaches in Norway so they had to put them all back in again.
