Study Notes

EIS General Description

EIS architecture is designed to ensure redundancy, segregation and reconfiguration.
There is no operational degradation in case of failure of an EIS Line Replaceable Unit.
The EIS architecture presents the aircraft system configuration reliably on Display Units (DUs) and has easy failure recovery procedures.

EFIS - PFD Presentation and Control

The Navigation Display (ND) presents navigation information with 5 different modes selectable by the crew on the EFIS control panel.
The SDACs fulfill three main functions:
- data acquisition from the aircraft systems,
- data concentration,
- data digitizing to be sent to the DMCs for display on the SD.
The DMCs directly receives aircraft systems data for display on the upper part of the EWD.
The SDACs receive and digitize aircraft system information concerning amber cautions and transmit it to the FWCs
The FWCs fulfill three main functions:
- data acquisition from some main aircraft systems,
- data warning computation (all warnings, memos, status),
- flight phase computation according to the aircraft configuration.
The FWCs directly receive aircraft system data concerning red warnings and generate memos.
All warning messages are generated by the FWCs which then activate attention getters such as the MASTER WARN/MASTER CAUT and AUTOLAND..
The FWCs also activate audio signals, and auto call outs (synthetic voices) broadcast by two loudspeakers (no volume control for the audio signals).
DMC 3 normally drives the EWD and the SD.
DMC 1 and DMC 2 are in standby mode and can be used in case of DMC 3 failure.
ECAM reconfiguration (DMCs and LCD units) can be achieved either automatically or manually through the ECAM switching panel.
The SD also receives a video signal from the taxi cameras.

ECAM Alert Classification

Level 2: Cautions mainly alert for system failures which have no immediate consequences on safety.
Level 2: Cautions are generally associated with a Single Chime (aural alert) and a MASTER CAUT amber light (steady visual alert).
Level 3: Warnings (highest priority) correspond to an emergency configuration.
Level 3: Warnings are triggered with the MASTER WARN flashing lights, a chime associated to the failure and a warning message.
The ECAM page is displayed automatically when a value drifts from its normal range, the affected parameter pulses and a white ADV message pulses at the bottom of the EWD.
For example, if the cabin altitude increases above its normal value, but is still well below the threshold of the warning, the CAB PRESS page appears automatically with a pulsing value for the cabin altitude.
The crew may revert to manual pressure control to prevent warning activation.

ECAM Dual Display Mode

In dual display mode (two ECAM Liquid Crystal Displays (LCD) units), the system displays relevant information on both LCDs.
If one ECAM LCD unit fails, the crew will be alerted by a white ADV message pulsing at the bottom of the EWD.
This indicates a system failure, but it does not affect the display on the remaining functional LCD unit.
If both LCDs fail (single display mode), a white ADV message pulses at the bottom of the EWD to attract the crew's attention.
This indicates that both LCDs are not working.
In this mode, the remaining healthy LCD unit will still function normally, displaying all relevant information.
