OH...Don' t I remember when the PHC aircraft got shifted to Warri....they were far from the standard maintained by the Engineers at Warri. The Sperry System was much...much...much better than the SFENA.
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?"
It seemed the FD's were not on the Shell Contract...thus out they came and put back on the Store Room Shelves in Redhill.....not that we flew single pilot IMC or anything in Nigeria.
