Thanks Greg,
Very neat. Could I ask what sort of accuracy (in terms of minutes/NMs are you getting with the 10' slide rule? I always assumed you needed 4+ places for Cel Nav, well for conventional cos formula LOPs anyway,perhaps I have this wrong? Perhaps ex meridian calculations need less accuracy?
Best wishes
Francis
