I'm well acquainted with the rather prominent bulge for the Sperry autopilot on RAAF Beaufighters but being the curious type, I've always wondered what was the specific reason that RAAF aircraft needed these and Beaufighters operated by different air arms didn't. I could assume it was due to large distances having to be flown over the Pacific but beyond that, I'm stumped. Any experts care to enlighten me please? Thanks, Clive.
