CFDS SPECIFIC PAGE PRESENTATION
The fuel system is a "type 1" system and is not
available in CFDS ’backup" mode.
FQIS STATUS
The FQIS STATUS allows access to channel 1 (or 2) BITE
memory, channel 1 has priority when both channels have
the same health.
A list is produced each time an FQIS LRU is detected
as being currently failed or deemed failed or at the
last FQI power-up test.
All failure classes are reported.
The operating grade for each channel is displayed and
decoded as follows:
- GRADE 1: normal operation,<R>
- GRADE 2: normal operation,<R>
- GRADE 3: normal operation with reduced
accuracy,
- GRADE 4: outside normal operation (display
blanked)
- GRADE 5: FQIC outputs.
FLSS STATUS
The last FLSS power-up test result is recorded in the
FQI channel which was the master at that time.
The FLSS BITE is run automatically 30s after power-up
and consists of four separate procedures displayed on
the MCDU page:
- BITE 1 - High level sensors, surge tank sensors,
- BITE 2 - Read intercell transfer valves, some
low level sensors,
- BITE 3 - Outer cell underfull sensors,
remaining low level sensors, FWD intercell
transfer valves,
- BITE 4 - Inner cell full/underfull sensors,
logic contol circuits, temperature sensors.
Selection of NEXT PAGE gives the list of failed BITE
4 FLSS LRUs.
EXAMPLE: BITE 4 has failed: - R underfull sensor and
L wing temperature sensor have failed.
NOTE: - the intercell transfer valves are reported
under FQIS status.
- FLSS status results are only kept on the channel
that was the master at power-up.

FQIS INPUT PARAMETER VALUES
The following information is provided:
- permitivity calculated from cadensicon,
- density calculated from cadensicon,
- permitivity calculated from CIC,
- fuel temperature in Inner and outer cells,
- effective pitch and roll attitudes.
FQIS PROBE CAPACITANCE VALUES
This page gives the values for all the capacitance
devices in the tanks.
FQIS DISCRETE INPUT VALUES
This page gives the states for all discrete inputs to
the FQIS.
A "1" represents the active state.
EXAMPLE: Bit position R3 is at "1" : means that the
refuel door is open.
