Use of the Air Almanac for Marine Navigation

This book is intended for readers who are either already familiar with celestial navigation or are planning to take up the subject, and want to learn about optional resources. This booklet does not teach celestial navigation, nor is it a copy of the Air Almanac.


There are marine navigators who prefer the Air Almanac over the Nautical Almanac. This booklet compares the two almanacs so others can make their choice as well.

Also included is an in-depth explanation with examples on how to use the Sky Diagrams to choose the best triad of celestial bodies for a round of sextant sights. This is a crucial step for an accurate cel nav fix, and these diagrams are the best way to manually make that selection. Results are compared with Pub 249 Vol 1 and 2102-D Star Finder solutions.

The Air Almanac is available online as a PDF download at no charge.
