To properly design aircraft instruments, avionics, and other equipment, which is installed in aircraft cabin areas, it is necessary to accurately know the cabin temperature environment. Aircraft cabin temperatures vary widely depending on the aircraft operating condition, basic design parameters, and type of environmental control system installed. It is suspected that high aircraft cabin static temperatures may increase aircraft component failure rates, cause equipment to temporarily malfunction, and directly cause equipment failure. However, accurate temperature data for the static environment are not available for many aircraft. To obtain this type of data, USAASTA, with the assistance of the United States Army Air Mobility Research and Development Laboratory Eustis Directorate, has conducted comprehensive static temperature surveys on five first-line United States Army helicopters.
