3. Fault Confirmation
__________________
A. During normal operation of the ECAM, the FUEL - AUTO FEED FAULT is a configuration warning.
NOTE : This ECAM warning is only given in certain flight phases, and is
____
controlled by the FWC.
This warning function is activated simultaneously with the FAULT legend on the P/BSW-CTR TK/MODE SEL/AUTO (48QA).
NOTE : The FAULT is only given with the P/BSW in the AUTO (in) position.
____
These indications are given because the fuel load distribution is not correct or the fuel has not been used in the correct sequence.
The warnings will be activated if for 60 seconds the fuel distribution (for any reason) is as follows:
- the left wing tank, less than 5000 kg (11000 lb) AND the center tank, more than 250 kg (550 lb).
- the right wing tank, less than 5000 kg (11000 lb) AND the center tank, more than 250 kg (550 lb).
The warnings will be reset immediately when the fuel distribution
conditions no longer exist.
The source of the comparison logic which activates and resets this
warning is contained in the FQIC (3QT).
The FQIC warning/FAULT logic output is inhibited during automatic
pressure refuel.
The FQIC warning/FAULT logic output is transmitted on:
- two (2) ARINC bus lines to the FWC (ECAM)
- two (2) discrete signal lines OR gated together to the P/BSW-CTR TK/MODE SEL/AUTO (48QA), FAULT legend.
(1) Examine the aircraft log/investigate the fuel configuration at the time of the original/repeat failure, and compare it with the fuel configuration given before.
(2) Do the Functional Test of the Center-Tank Fuel Control (Ref. AMM TASK 28-21-00-720-001).
(3) If a CTR TK PUMP 1 failure in Manual Mode is found:
- do Center Tank Pump-Fuel No 1 System Failure (Ref. TASK 28-21-00-810-813).
(4) If a CTR TK PUMP 2 failure in Manual Mode is found:
- do Center Tank Pump-Fuel No 2 System Failure (Ref. TASK 28-21-00-810-814).
