1976 Standard Atmosphere

1976 Standard Atmosphere can calculate several physical parameters, based on the user provided altitude value. The Java-based utility can run on several operating systems and it is useful for scientists, teachers or any user who wishes to calculate certain physical parameters.

Calculate altitude dependent parameters

1976 Standard Atmosphere can calculate a large series of parameters, based on the altitude value you provide. You may enter the altitude above mean sea level - the field indicated by the lower case letter “h”, then watch as the rest of the parameters are automatically calculated.
The program can display the values for the temperature at the indicated altitude, based on the mathematical algorithm, as well as the true airspeed, the dynamic pressure, total temperature or density ratio at the given altitude.
The static density at a certain altitude, the speed of sound, equivalent airspeed, total density, dynamic viscosity coefficient and the pressure ratio can also instantly be calculated.

Automatic or manual input

Additional variables include the static pressure at a certain altitude, the Match number (ratio of the local true airspeed and speed of sound), calibrated airspeed, total pressure temperature ratio or the Reynolds number.
1976 Standard Atmosphere allows you to enter the preferred value for any of the above-mentioned parameters. Simply check the ‘Manually Input’ box and enter the desired value before the program calculates the rest of the parameters. You may also save the results as a specific file, on your computer, so you may load it at any time.

Choose the measurement units

1976 Standard Atmosphere allows you to obtain the desired results, based on the measurement system you select. The length can be measured according to the metric or the imperial system, and one of three subdivisions. The temperature is estimated in Celsius, Fahrenheit, Kelvin or Rankine degrees while the pressure can be measured in Newtons per square centimeters, bars, pounds per square foot or atmospheric units.
