ECAM = Electronic Centralized Aircraft Monitoring (AIRBUS specific).

It performs three main functions:

• Data acquisition and concentration
• Data warning computation
• Warning announcement and data display.

The whole ECAM system is composed of several subsystems, each performing specific tasks:

• SDACs – System Data Acquisition Concentrators that acquire aircraft systems malfunction/failures to send them to the FWCs for generation of the corresponding alert and procedure messages.
• FWCs – Flight Warning Computers generating alphanumeric codes corresponding to all alerts messages to be displayed on ECAM Display Units (DUs).
• DMCs – Display Management Computers that receive data from aircraft systems either directly or through the SDACs and FWCs and display them on the Display Units (DUs) of the ECAM.
• ECAM interface – ECAM control panel, warning and caution lights, loudspeakers, DUs.
