- or warning/caution messages, giving the title of the failure and the corresponding procedures/actions to be performed. - on the R part
-
either Memo messages
- or title of the A/C system pages presenting parameters concerned with a secondary failure.
(3) 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 eventually
- or status messages, i.e.:
-
an operational summary of the aircraft condition
-
an explanation of possible autoland capability downgrading
-indications of the aircraft status following all failures except those that do not affect the flight
1EFF : ALL 1 31-50-00Page 41 1 1 Feb 01/01R 1 1 1CES 1
-general contents, limitations (speed, altitude), peculiar or
emergency postponable procedures, informations, etc... These STATUS messages appear once the crew has cleared all the pages corresponding to the current warning/caution, or upon manual call. 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).

Messages presentation The following rules are followed:
-wording and abbreviations are consistent with the overhead panel
-after action, the message either changes in color or disappears.
(5)
Messages display operational modes
(a) Types of Warnings/Cautions There are three distinct types of warnings/cautions:
-
those associated with an independent failure
-
those associated with a primary failure
-
those associated with a secondary failure.
1_ Independent failure:
This is a failure which affects an isolated item of equipment
or system without affecting the other items of equipment or
systems on the aircraft.
2_ Primary failure
This is a failure of an item of equipment or system causing
the loss of other items of equipment which depend on it.
This configuration constitutes a cascade of failure all
originating from the same primary failure.
e.g. : HYD B SYS LO PR failure leads to the loss of: SPLRS 3.
3_ Secondary failure
This is the loss of an item of equipment or system resulting
from a primary failure.
This apparent failure could, in some cases, disappear after
corrective crew action.
NOTE : Different failures combination may occur sequentially____
or simultaneously.
(b) Normal operation When there is no current A/C system failure or when all the requested actions corresponding to the last failure have been performed and the ECAM pages related to this failure have been cleared, the upper display bottom third shows MEMO messages (and some elements of normal check list in TO or APPR) and the lower
1EFF : ALL 1 31-50-00Page 42 1 1 Feb 01/01R 1 1 1CES 1
display presents the synoptic diagram related to the present
flight phase.
(Ref. Fig. 020)
(c) MEMO information (Ref. Fig. 021) MEMO messages are presented on the lower part of the upper ECAM DU when there is no warning/caution message to be presented. Complete list of the possible MEMO messages is given hereafter. They are presented in the following priority order:
-------------------------------------------------------------------------------| LEFT PART | RIGHT PART | |--------------------------------------|--------------------------------------| | T.O MEMO (G)(refer to the list below)| SPEED BRAKES (A) (G) | | LDG MEMO (G)(refer to the list below)| PARK BRK (A) (G) | | REFUELG (G) | HYD PTU (G) | | IRS IN ALIGN x MN (A) (G) | RAT OUT (A) (G) | | IRS IN ALIGN (A) (G) | EMER GEN (G) | | IRS ALIGNED (G) | RAM AIR ON (G) | | | IGNITION (G) |
