Description: The Sight Reduction Tables for Air Navigation consist of three volumes of comprehensive tables of altitude and
azimuth designed for the rapid reduction of astronomical sights. The present volume (Volume 1) contains tables
for selected stars for all latitudes, calculated for the epoch of 2025.0, and replaces the previous edition calculated
for the epoch of 2020.0. It is intended for use for about 5 years, when a new edition based on a later epoch will be
issued. Volume 2 for latitudes 0°-40° and Volume 3 for latitudes 39°-89° are permanent tables for integral
degrees of declination. They provide sight reduction for bodies with declinations within 30° north or south of
the equator, which includes the Sun, Moon, planets and most of the navigational stars.
