What is the function of the Display Management Computer (DMC)?

Three identical DMCs obtain data from different sensors and computers and send it to the display units. Each DMC can simultaneously supply one PFD one ND and both ECAM display units.

3

What is the function of the EIS DMC Switching Selector?

A switch near the center of the SWITCHING panel (above the ECAM control panel)  enables the flight crew to replace the Captain's or FO's Display Management Computer (DMC1 or DMC2 by DMC3).

4

What is the function of the Flight Warning Computer (FWC)?

Two identical FWCs generate alert messages memos aural alerts and synthetic voice messages.

5

What represents the Flight Path Vector (FPV)?

The FPV represents the lateral and vertical trajectory of the aircraft with respect to the ground.

6

8

What is the function of the System Data Acquisition Computer (SDAC)?

Two identical SDACs acquire data  then generate signals. Some of these signals go to the three DMCs  which use them to generate displays of system pages and engine parameter. Others go to the flight warning computers  which use them to generate ECAM messages and aural alerts.

9

When is the sideslip target blue?

The sideslip target is blue  if CONF 1, 2 or 3 is selected and any ENG N1> 80% or one thrust lever > MCT (>= FLX if FLX or DERATED TO) and the difference between the engine N1's exceeds 35%.
