The FQIC trouble shooting data can also be accessed from:
- PREVIOUS LEGS REPORT
- FQIS STATUS.
The FLSCU trouble-shooting data can also be accessed from:
- PREVIOUS LEGS REPORT
- FLSS STATUS.
NOTE : Cadensicon trouble-shooting data for internal faults can be
____
accessed from:
- CLASS 3 FAULTS
- FQIS STATUS.
(2) PREVIOUS LEGS REPORT The PREVIOUS LEGS REPORT identifies all the class 1 and 2 LRUs which have been detected as unserviceable during the previous flight legs, up to a maximum of 63 flight legs. The parameters used to identify each LRU are as follows:
- description
- FIN
- flight leg
- date
- time (GMT/UTC) of the first detection of the failure for each flight leg
- ATA number.
If the FQIC has been installed in more than one aircraft. Each page
is identified by the aircraft tail number.
The most recent flight leg is identified by -01, the flight before by
-02 etc., the most recent failures being shown first.
Where the FQIC or either FLSCU has been found unserviceable, internal
trouble-shooting data can be accessed and decoded in the same way as
for the LAST LEG REPORT.
(3) LRU IDENTIFICATION The selection of this option will show the FQIC and the OBRM combined part number. The part number shown must agree with the part number of that LRU installed in the aircraft. EXAMPLE FQIC SIC 5095-HH-00-SS Where:
- HH is the computer hardware standard (e.g. 03, 11)
- 00 is the OBRM hardware standard (e.g. 01, 02)
- SS is the software standard (07).
For 07 Software, and current in service units, one of the part numbers that follow will be shown:
- SIC 5059-03-01-07
- SIC 5059-03-02-07
- SIC 5059-11-01-07

(4) CLASS 3 FAULTS This option shows the Class 3 faults (up to a maximum of 63 flight legs) known to the FQIC. Each LRU is identified by the same parameters as those on the PREVIOUS LEGS REPORT. Where any cadensicon has been found as unserviceable, internal trouble-shooting can be accessed and decoded in the same way as for the FQIC and FLSCU. See LAST LEG REPORT.
(5) SELECT CHANNEL Each menu mode transmission can be called from the other channel by by use of the SELECT CHANNEL option. The channel with the best grade will get control when Normal Mode is re-entered. To get back to Normal Mode select RETURN on the MCDU. The CFDS will then send a logoff command to the FQIC, which must then go back to Normal Mode.
(6) FQIS STATUS This option permits access to channel 1 or channel 2 BITE memory, as set on channel selection (see para., (5) above). A list is made of every FQIS LRU known or thought to be defective currently, or at the last power-on BITE test. All failure classes are reported and where the FQIC or a cadensicon is defective, trouble-shooting data can be accessed by the same procedure as for the LAST LEG REPORT.
The operating grade number for each channel is also shown and is decoded as follows:
----------------------------------------------------------------------------
| GRADE | System Operational Effect |
|-------|--------------------------------------------------------------------|
| 1 | Correct operation. |
| | In this grade the FQIS can be fully serviceable or contain the |
| | failures as follows: |
| | - a single probe failure in any tank (does not include 34QT1(2) |
| | probe failures which are Grade 3) |
| | - density out of range |
| | - cadensicon permittivity out of range |
| | - the A value out of range (calculated from density and |
| | permittivity) |
| | |
| | (The A value is a fuel characteristic dependent on density and |
