B. Information Presented on ECAM DUs (Ref. Fig. 003) The upper and lower ECAM screen surfaces are shared in two zones each. The upper ECAM DU is called Engine/Warning (E/W) Display unit. The upper zone (approximately two thirds of the screen surface) shows all the engine primary-parameter indications, plus the onboard fuel quantity and the flaps/slats position indications. The lower zone presents various kinds of messages, described in 31-50-00:
-MEMO and aircraft configuration items
-WARNING/CAUTION messages
-TITLES of aircraft system pages related to WARNING/CAUTION.
The lower ECAM DU is called System or Status (S) Display Unit.
The upper zone (approximately three quarters of the screen surface)
shows:
-either aircraft system synoptic-diagrams
- or STATUS messages, described in 31-50-00.
The lower zone presents several permanent parameter values such as: TAT,
SAT, UTC, A/C weight, A/C G. LOAD (only when it is excessive) and at last
the selected altitude value expressed in meters on pilot's request.
In normal configuration, without aircraft system failure, the ECAM system improves crew comfort through elimination of the need for frequent scanning of the various system panels for:
-Routine system monitoring: system synoptic diagrams are displayed on the lower DU and automatically adapted to the present flight phase or manually called.
-System parameter monitoring: some system parameters are monitored the whole flight. They are automatically displayed on the relevant system page when their value drifts out of normal range but well before the warning level is reached.
(1) Engine primary-parameter indications For each engine, the primary parameter indications N1, N2, EGT and FF are constantly displayed. Engine management main-parameters N1 Limit and corresponding operating mode, N1 command and/or predictive N1 are also displayed. For each engine, the predictive N1 is the N1 value which corresponds to the throttle position. N1 actual = N1 predictive in stabilized operation.

The following figure gives a complete block diagram of the EIS system.
(Ref. Fig. 004)
The following figures show the location of the system components:
(Ref. Fig. 005, 006, 007)
The complete system includes the following components:
-
2 DUs housed in racks on the Captain's main instrument panel
-
2 DUs housed in racks on the First Officer's main instrument panel
-
2 DUs housed in racks on the center instrument panel
-3 DMCs (Display Management Computers) common to the EFIS and ECAM systems, located in the avionics compartment
-2 SDACs (System Data Acquisition Concentrators) located in the avionics compartment
-
1 dual EFIS/FCU, located on the glareshield, and called the FCU (Flight Control Unit) which includes CAPT and F/O EFIS control sections
-
1 ECAM control panel, located on the center pedestal
-One set of transfer selector switches accessible to the Captain and the First Officer located on the center pedestal. They provide EIS reconfiguration controls in case of DMC or ECAM DU failure
-Control/brightness potentiometers for the DUs: those concerning the EFIS DUs are located on the left side of the CAPT and on the right side of the F/O instrument panel (301VU and 500VU) those concerning the ECAM DUs are located on the ECAM control panel
-One PFD/ND transfer pushbutton switch for each pilot, located between the PFD and ND control/brightness potentiometers.
-Two sets of visual attention lights, located on the glareshield, on either side of the FCU, each of them includes a MASTER WARN light and a MASTER CAUT light; these lights are of the pushbutton switch type
