Tony I dont think you will find it had a specific use, it should be dated and that should used to establish what aircraft were around at the time with suitable performance. The use of knots ASIs has been debated here before and as a general rule it seems to be applied to naval aircraft during most of the war and MPH used by land based aircraft.
