Studies of the Army Aviation (V/STOL) Environment. Report No. 7. Worldwide Distributions of Ambient Temperatures and Temperatures of Materiel Exposed to Direct Solar Radiation.
Studies have shown that the effects of temperatures are the major causes for aircraft failures in the field. Natural temperatures, including ambient shade and exposed or those resulting from direct solar radiation, are considered; induced temperatures which are not natural are not included in this r...
