"The Air Almanac was originally intended for air navigators, but is used today mostly by a segment of the maritime community. In general, the information is similar to the Nautical Almanac, but is given to a precision of 1' of arc and 1 second of time, at intervals of 10 minutes (values for the Sun and Aries are given to a precision of 0.1').
This publication is suitable for ordinary navigation at SEA, but lacks the precision of the Nautical Almanac, and provides GHA and declination for only the 57 commonly used navigation stars."
