DETERMINATION OF THE PERCENT OF TIME THE GROUND IS VISIBLE FROM AN AIRCRAFT FLYING ABOVE CLOUDS

Abstract

Equations were derived to express the percent of time the ground is visible from an aircraft flying above various conditions of cloudiness. To permit rapid solution of the equations over a wide range of cloud dimensions and aircraft height, nomographic charts were constructed. The assumptions made to simplify the equations, and the intended applications of the equations, are discussed.
