(a) Lower ECAM display unit
In normal operation, the Display Unit presents:
-either an A/C system synoptic diagram, corresponding to the current phase of flight or to the crew manual selection, or to the automatically called system page corresponding to the caution/ warning that is shown to the crew on the upper DU.
- or a status message (Refer to 31-50-00).
At last, the two bottom lines are reserved for the permanent
display of A/C parameters such as TAT, SAT, A/C Gross weight, and
TIME (UTC).
(3) A/C system presentation In normal configuration, the lower ECAM DU presents:
-either STATUS messages
- or, when all messages/texts have been cleared, one of the 12 A/C system pages of which the list is given hereunder:
-
air bleed
-
air conditioning
-cabin pressurization
-electrical power supply (AC and DC)
-flight controls
-fuel
-hydraulic
-APU
-engine monitoring
-doors/oxygen
-landing gear/wheels/brakes (plus ground spoilers)
-cruise These system pages present A/C system information required for efficient operation of the A/C.
(a) System presentation (synoptic diagram)
-Symbology Appropriate symbols are used to represent all the components (pumps, valves, etc...) in their various states (running, open, close, etc...). Appropriate symbology is used to show lines and flow direction (for fuel, hydraulic, electrical power supply, air, ...).
-Color coding
The part of the synoptic diagram is :

(b) Logic for presentation of A/C system pages These pages are presented upon either manual or automatic selection according to a logic. The different selection modes for these A/C system pages are as follows:
-
Automatic mode related to a failure As soon as the FWC detects a warning, the relevant system page is automatically shown, associated with the first warning message. This mode is intended for allowing the crew to cross-check on the display the part of the A/C system no longer usable/reliable and to follow the result of corrective actions. As the text of the warning message changes following corrective actions, the system page changes accordingly.
-
Automatic Advisory mode (Ref. Fig. 032) When a parameter drifts out of normal range, the relevant system page is automatically displayed in order to attract crew attention well before the warning level is reached. The corresponding key on the ECAM control panel comes on. Special means are used to draw crew's attention to the concerned parameter: the indication (green) and the system page title (white) pulse smoothly as long as there is an exceedance. Every time one or several parameters of a system exceed a given advisory threshold for a time longer than 2.5s the advisory mode is armed for the corresponding system page. However, if the value of the parameter exceeds the corresponding alert level, the associated caution or warning is triggered and the indication is displayed in amber or in red. For each parameter susceptible of an advisory, the advisory mode is inhibited in some flight phases. However, as long as an A/C system page is on display, the inhibitions for the advisory mode concerning all the parameters presented are not taken into account.
