Cooling of the cockpit in high-performance aircraft is usually based upon avionics requirements, with only secondary regard for the effect on aircrew. A shift in priority may now be needed because the new fighter aircraft demand maximal human performance which may be impaired by heat stress. This paper reviews current USAF specifications for the cockpit environmental control system (ECS) together with evidence that hot-weather flight operations involve significant aircrew heat exposure. A brief analysis is made of heat stress are discussed. A new approach is suggested for writing ECS specifications in order to ensure adequate aircrew protection and optimal man-machine system performance.
