The Environmental Control System (ECS) of an aircraft provides air supply, thermal control, and cabin pressurization for the crew and passengers. The functions of avionics cooling, smoke detection, and ﬁre suppression are also commonly considered to be part of the aircraft environmental control system.
To achieve the desired temperature, bleed-air from the engine fan is passed through a heat exchanger, called a pre-cooler, which absorbs excess heat from the air. The Fan Air Modulating Valve (FAMV) also aids in controlling the ﬁnal air temperature by varying the amount of airﬂow.
