Beaufighter Compass Problems
I asked Frank about the problems with the compass after firing the cannons and he confirmed that it was so. However, he couldn't remember curing it by firing the guns again on a northerly heading mentioned by Walter (7855). Frank remembers having to carry out a compass swing while airborne using known landmarks. The thought of doing that while over enemy territory, and looking for enemy fighters, is yet another fact which fills me with awe at what these guys did.
Anyway, COMING SOONto a thread near you:
Some genuine 1941 RAF Navigation Exams (just as soon as I can be confident of up loading them without bringing Pprune crashing down)
