B. Cockpit Indications
If specified failures or system configurations occur in the main fuel pump system:
-
the Flight Warning Computer (FWC) (Ref. 31-52-00) gives an aural and visual warning
-
the ECAM shows a failure message on the EWD, and the FUEL page on the
SD. If necessary, a procedure to correct the effects of the failure is also given with the warning message.
(1) EWD Messages
The warning messages given are:
(a)
FUEL L TK PUMP 1 LO PR The No. 1 main pump is set to on, but low pressure has occurred (equivalent warning messages are given for the R TK PUMP 1).
(b)
FUEL L TK PUMP 2 LO PR The No. 2 main pump is set to on, but low pressure has occurred (equivalent warning messages are given for the R TK PUMP 2).
(c)
FUEL L TK PUMPS 1+2 LO PR Both the fuel pumps in the LH wing are set to on, but low pressure has occurred (an equivalent warning message is given for the R TK PUMPS 1+2).
R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 401-499,
(d)
FUEL CTR TK PUMP 1 LO PR The center tank pump 1 (LH) is set to on, but low pressure has occurred (Equivalent warning message for center tank pump 2 (RH)).
(e)
FUEL CTR TK PUMPS LO PR The center tank pumps 1 and 2 are set to on, but low pressure has occurred.
(f)
FUEL CTR TK PUMPS OFF The center tank pumps are set to OFF, but no failure has occured.

(g) FUEL AUTO FEED FAULT The fuel pumps are set to on and the MODE SEL P/BSW is pushed in (auto mode), with the fuel condition as follows: - left or right wing tank contains less than 5000 kg (11000 lb) of fuel - center tank contains more than 250 kg (550 lb) of fuel. The center tank pumps do not stop after the slats are extended. The center tank pumps do not stop 5 minutes after the related low level sensors are dry.
