Description:
Air Publication Number: AP 1602
This publication, produced to the requirements
of the Royal Air Force, presents in tabular and graphical form astronomical
data required for the planning of activities, in particular aircraft movements,
where the amount of daylight, the duration of twilight, and the position and
phase of the Moon are important. It replaces The Air Almanac which
last appeared in 1997. This annual volume contains data for the times of rising
and setting of the Sun and Moon, as well as the twilight times for latitudes
between North 72° and South 60°. Graphical methods for determining
this information at altitudes of up to 60,000 feet and at high latitudes are
also provided, as are standard times for many places around the world.
