ECAM
 
PURPOSE OF THE ECAM
Applicable to: ALL
The Electronic Centralized Aircraft Monitoring (ECAM) system is a main component of Airbus’ two-crewmember cockpit, which also takes the "dark cockpit" and "forward-facing crew" philosophies into account.
The purpose of the ECAM is to:
? Display aircraft system information
? Monitor aircraft systems
? Indicate required flight crew actions, in most normal, abnormal and emergency situations.
As the ECAM is available in most failure situations, it is a significant step in the direction towards a paperless cockpit and the reduction of memory items.
MAIN PRINCIPLES
Applicable to: ALL
INFORMATION PROVIDED WHEN NEEDED
One of the main advantages of the ECAM is that it displays applicable information to the flight crew, on an "as needed" basis.
The following outlines the ECAM’s operating modes:
? Normal Mode:
Automatically displays systems and memos, in accordance with the flight phase.
? Failure Mode:
Automatically displays the appropriate emergency/abnormal procedures, in addition to their associated system synoptic.
? Advisory Mode:
Automatically displays the appropriate system synoptic, associated with a drifting parameter.
? Manual Mode:
Enables the flight crew to manually select any system synoptic via the ECAM Control Panel (ECP).
Most warnings and cautions are inhibited during critical phases of flight (T/O INHIBIT – LDG
INHIBIT), because most system failures will not affect the aircraft’s ability to continue a takeoff or landing.
FAILURE LEVELS
The ECAM has three levels of warnings and cautions. Each level is based on the associated operational consequence(s) of the failure. Failures will appear in a specific color, according to a defined color-coding system, that advises the flight crew of the urgency of a situation in an

instinctive, unambiguous manner. In addition, Level 2 and 3 failures are accompanied by a specific aural warning: A Continuous Repetitive Chime (CRC) indicates a Level 3 failure, and a Single Chime (SC) indicates a Level 2 failure.
Failure Level Priority Color Coding Aural Warning Recommended Crew Action
Level 3 Safety Red CRC Immediate
Level 2 Abnormal Amber SC Awareness, then action
Level 1 Degradation Amber None Awareness, then Monitoring

When there are several failures, the FWC displays them on the Engine Warning Display (E/WD) in an order of priority, determined by the severity of the operational consequences. This ensures that the flight crew sees the most important failures first.
FEEDBACK
The ECAM provides the flight crew with feedback, after action is taken on affected controls:
