ESDU 68046: Atmospheric data for performance calculations.

Abstract:

ESDU 68046 provides tables of the properties of the International Standard Atmosphere for use in aircraft performance calculations in commonly used units. They contain the parameters most frequently used in such work. Properties of off-standard atmospheres are also provided. Within the height ranges covered all the data are consistent with the USA, ICAO, and ISO Standard Atmospheres. ESDU 72018 provides tables for the International Standard Atmosphere with heights in feet and other properties in SI units. ESDU 77022 provides equations for calculating values of properties of the International Standard Atmosphere and ESDU 78012 provides equations for non-standard atmospheres.

Toolbox ISA Run

Title	International Standard Atmosphere app
Version	1.1
Details	The app evaluates, at a given pressure altitude, pressure, temperature and density (and their corresponding relative values) together with the absolute values of the speed of sound, kinematic and dynamic viscosity and thermal conductivity. It also determines V_TAS, V_EAS, kinetic pressure and unit Reynolds number for a specified Mach number at the given pressure altitude. Calculations are limited to the troposphere and stratosphere in the ISA.
