ECAM is actually a series of systems designed to work in unison to display information to the pilots in a quick and effective manner. Sensors placed throughout the aircraft, monitoring key parameters, feed their data into two System Data Acquisition Concentrator (SDACs) which in turn process the data and feed it to two Flight Warning Computers (FWCs). The FWCs check for discrepancies in the data and then display the data on the ECAM displays through the three Display Management Computers (DMCs).
