Deflection Plotting was a British concept for adjusting a torpedo director first proposed by Template:CmdrRN A. M. Yeats Brown. The "steady bearing" concept of Hallett's Director was a subcase.
A pamphlet was drawn up and issued in 1912,[1] and a combination slide rule and plotting board invented by Template:LieutGRN W. M. James[2] to facilitate its practice, permitted the required deflection to be read off rather than calculated as detailed in the pamphlet.
Tests were underway to use the calculator with a system designed by Template:LieutTRN B. E. Reinold to permit a rangefinder, gyrocompass receiver and Forbes speed indicator to automate the process further.[3]
Abolished
In mid 1919, a meeting of the Fleet Torpedo Committee decreed that "deflection plotters" should be abolished, as their results, if accurate, were stale.[4]
