Each failed LRU is identified by its:
- description
- FIN
- time (GMT/UTC) at which the failure was first detected
- ATA number.

Where the FQIC or any cadensicon has been found unserviceable, internal trouble-shooting data can be accessed and decoded in the same way as for the LAST LEG REPORT.
(7) FLSS STATUS The selection of this option on the master channel will cause a list to be made of any FLSS or Inter Cell Transfer Valve (ICTV) failures detected since power-on. The list is updated by the last automatic FLSS BITE or COMMAND FLSS BITE tests. The last results are shown overwriting any previous test results. The selection of this option on the slave channel will cause the message FLSS NOT AVAILABLE ON THIS CHANNEL to be shown. The option to change to the master channel is also given.
All failure classes are reported.
Each failed LRU is identified by its:
- description
- FIN
- time (GMT/UTC) at which the failure was first detected
- ATA number.
Where one of the two FLSCUs is reported defective, trouble-shooting data can be accessed by the same procedure as for the LAST LEG REPORT.
FLSS BITE
For the function of the FLSS BITE the sensors are divided into six groups, (see below). Which group or combination of groups is tested is controlled by:
- the type of test
- the electrical power conditions
- the fuel quantity conditions.
-----------------------------------------------------------------------------| Group | Description | Sensors (FINS) | BITE | |---------------------------|-------------------------------------------------| | 1 | High Levels | 17QJ1(2), 20QJ, 6QJ | 1 | |---------------------------|-------------------------------------------------| | 2 | Center low levels | 21QJ, 22QJ | 2 | |-----------------------------------------------------------------------------| | 3 | Wing low levels | 15QJ1(2), 16QJ1(2), 39QJ1(2) | 2 & 3 | |-----------------------------------------------------------------------------| | 4 | Surges, control | 28QJ1(2), 27QJ1(2), 25QJ1(2), 26QJ1(2) | 1 & 4 | | | | 29QJ1(2), 30QJ1(2), LOGIC 1, LOGIC 2 | | |-----------------------------------------------------------------------------| | 5 | Control | 38QJ1(2), 24QJ1(2) | 4 | |-----------------------------------------------------------------------------| | 6 | Control | 23QJ1(2) | 4 | -----------------------------------------------------------------------------
