Air Navigation
Sight Reduction Tables for Air Navigation, or simply Navigation by Celestaire and the UK Hydrographic Office are split into 3 volumes:
Volume 1 contains some stars (whose declinations may be more than 29°) that are pre-selected for optimum viewing and direction. This volume is applicable for an 8 year period, centered on its Epoch date.
Volume 2 covers lattitudes 0-40 & Volume 3 covers latitudes 39-89, but work only for declinations from 0° to 29° north or south. This covers the sun, moon, planets, and only those stars whose declinations fall into this range.
