Airborne compass swings
My log book records that I flew several compass swing sorties during the period Feb-April 1946 while at Hmawbi (approx 40 miles north of Rangoon), accompanied by SNCOs of the then trade of 'Compass Swing Specialist (or whatever). I have no memory of how the procedure was actually carried out, other than that I complied with such requests from them as to heading etc to be flown.
Hmawbi, having a PSP runway and taxyways,would have been quite unsuitable for a ground swing, so perhaps this trade was established to deal with the problem; for sure, after our squadron moved to Hong Kong, I logged no further airborne swings.
