Hi Robin Stuart & All. Here’s a special treat for you this fine sunny Nov28th. While looking for dome refraction this morning, I came across this table in the 1938 issue of AP1618 Vol L 50-54 degrees N&S, a sort of predecessor to the air almanac and AP3270 combined. It shows the difference between Rhumb Line and Great Circle Distances from 52N to latitudes 60S to 60N for various changes in longitude. Presumably Vols A to whatever had tables from their own particular starting latitudes. DaveP
