Warmtoast,
Yours was on Pilot's Brevet" at p.229/4578. Now imagine you have four on your plate at once. "One-armed paper-hanger" doesn't come near it !
The CR/DF (and the later CA/DF) came in to the Approach Room, and you were out of business for all practical purposes. Ingenious lads put the spare time to good use, one chap at Valley made lead soldiers ! (my tale somewhere on that Thread).
BEagle takes up the story two Posts later (#4580 - "Here's the CRDF chart for RAF Valley in 1954:") Now a Controller worth his salt could manage four-in-hand, provided that the pilots did exactly what they were told when they were told. Much less if some sadist added a problem such as "No Compass", "No Compass, No Gyro", "Speechless", "Double flame Out" or any combination of the above.... We earned our dosh and came off watch like wet rags !
But it was a good life !
Danny.
