INTRODUCTION The environmental control system (ECS) provides temperature and pressure regulated air for heating, ventilating and pressurizing the flight and passenger compartments. Exhaust air, from the compartments, is used to ventilate the avionics and cargo compartments, before being dumped overboard through two outflow valves. For ground operations, pneumatic air to operate the ECS can be obtained from: S A ground air supply cart connected to the aircraft S The auxiliary power unit (APU) S Either or both engines. During flight, the engines normally supply bleed air for operating the air-conditioning, pressurization, and avionics cooling systems. ECS warnings and cautions are displayed on the engine indication and crew alerting system (EICAS) primary page. ECS advisory and status messages are displayed on the EICAS status page. Views of the aircraft ECS temperature, pressure, valve positions and system status indications are displayed on the EICAS ECS synoptic page.
