Sight Reduction Tables for Air Navigation (aka: Rapid Sight Reduction Tables for Navigation)

Volume I, used by both the marine and air navigator, contains altitude (to the nearest minutes) and true azimuth values of seven selected stars for the complete ranges of latitude and hour angle of Aries. These seven stars represent the best selection for observation at any given position and time, and provide the data for presetting instruments before observation and for sight reduction afterwards.

Volumes II and III cover latitudes 0°- 40° and 39°- 89° respectively and are primarily used by the air navigator in conjunction with observations of celestial bodies to calculate the geographic position of the observer.

Volume 1 – (Selected Stars) Epoch 2025 (good thru 2029)
Volume 2 – Latitudes 0°- 40°, Declinations 0°- 29°
Volume 3 – Latitudes 39°- 89°, Declinations 0°- 29°


Volume 1 contains the altitude to 1' and true azimuth to 1° for the seven stars most suitable for finding your position with a sextant, for the complete range of latitudes and hour angles of Aries. The latest edition is that for epoch 2020.0, published at the end of March 2017. This publication is aimed at the navigator using astro-navigation and provides the optimum selection of stars for a three-star fix.

Volume 2 and Volume 3 contain values of the altitude to 1' and azimuth to 1° for integral degrees of declination from 29° north to 29° south, for the complete range of latitudes and for all hour angles at which the zenith distance is less than 95° (97° between latitudes 70° and the poles) providing for sights of the Sun, Moon and planets. Volume 2 covers latitudes between 0° and 40°. Volume 3 covers latitudes between 39° and 89°.
