Abstract:

Atmospheric density, especially low values thereof, is important to aircraft takeoff and landing operations. Such extremes must be considered in aircraft design and are therefore to be included in MIL-STD-210B. This document provides environmental design criteria to designers of military equipment, and requires for the most extreme area and month, values of low density that are equaled or surpassed during, 1, 5, 10, and 20 percent of the time for ground elevations up to 15,000 feet. Typical temperatures accompanying these values, needed for engine power calculations, are also required. This report provides these densities and temperatures. In addition, empirical equations, being used by the USAF Environmental Technical Applications Center, for estimating extremes of low density near the ground, are evaluated.
