Earth's rotation affects bubble of bubble sextant used in aircraft, necessitating application of correction that increases in magnitude with increase in latitude and increase in ground speed; tables listing correction as function of ground speed and latitude are given in Air Almanac and indicate that correction to be applied is independent of course of aircraft; theoretic treatment given suggests, however, that correction is dependent in part on direction of motion of aircraft.
