An electronic centralised aircraft monitoring (ECAM) or electronic centralized aircraft monitoring is a system on Airbus aircraft that monitor aircraft functions and relays them to the pilots. It also produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem.
History
ECAM is similar to other systems, known as
Engine Indicating and Crew Alerting System (EICAS), used by

developed ECAM, such that it not only provided the features of EICAS, but also displayed corrective action to be taken by the pilot, as well as system limitations after the failures. Using a colour-coded scheme the pilots can instantly assess the situation and decide on the actions to be taken. It was designed to ease pilot stress in abnormal and emergency situations, by designing a paperless

System design
ECAM is a series of systems designed to work in unison to display information to the pilots in a quick and effective manner.
Sensor
A sensor is often defined as a device that receives and responds to a signal or stimulus. The stimulus is the quantity, property, or condition that is sensed and converted into electrical signal.
In the broadest definition, a sensor is a devi ...
s 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). In the event of a fault the FWCs generate the appropriate warning messages and sounds. More vital systems are routed directly through the FWCs such that failures in them can still be detected even with the loss of both SDACs. The whole system can continue to operate even with a failure of one SDAC and one FWC.
Failures are classed by importance ranging from level 1 failures to level 3 failures. In the event of simultaneous failures the most critical failure is displayed first. The warning hierarchy is as follows:
* Level 3 Failures: red warnings, situations that require immediate crew action and that place the flight in danger. For example, an engine fire or loss of cabin pressure. They are enunciated with a red master warning light, a warning (red) ECAM message and a continuous repetitive chime or a specific sound or a synthetic voice. The chime can be silenced by pressing the master warning push button.
* Level 2 Failures: amber cautions, failures that require crew attention but not immediate action. For example, air bleed failure or fuel fault. They have no direct consequence to flight safety and are shown to the crew through an amber master caution light, a caution (amber) ECAM message and a single chime.
* Level 1 Failures: Cautions, failures and faults that lead to a loss of system redundancy, they require monitoring but present no hazard. Examples include the loss of DMC3 when not in use. Level 1 failures are enunciated by a caution (amber) ECAM message only (no aural warning).
In addition to the three failure levels are following status messages:
* Advisory: System parameters' monitoring. It causes an automatic call of the relevant system page on the system display (S/D). The affected parameter pulses green.
* MEMO: Information: Recalls normal or automatic selection of functions which are temporarily used. It causes a green, amber, or magenta message on engine warning display (E/WD).

Limitations
The
Qantas Flight 32 engine failure generated more than 80 ECAM alerts, whose treatment took over an hour to complete.
