FUEL QUANTITY INDICATION (FQI) SYSTEM
Applicable to:
MSN,
The FQI is a computerized system that :
transmits the actual total fuel mass, as well as the quantity and temperature ‐ of fuel in the tanks, to
the ECAM.
‐ controls automatic refueling.
Two channels perform fuel computations : channel 2 activates automatically if channel 1 fails.
The FQI system has :
‐ an FQI computer.
‐ a set of capacitance probes in each tank to measure fuel level and temperature.
‐ one densitometer (cadensicon) sensor in each wing inner tank permitting the calculation of the fuel
quantity.
‐ one Capacitance Index Compensator (CIC) in each inner tank giving the dielectric constant of the
fuel in case of cadensicon failure.
‐ a quantity indicator for each tank installed on the refuel/defuel panel.
‐ a preselector on the refuel/defuel panel that shows the preselected and actual total fuel quantity.

FUEL LEVEL SENSING CONTROL UNIT (FLSCU)
Applicable to:
MSN,
The fuel level system generates fuel-level and fuel-temperature signals in order to operate the
appropriate switching functions for refueling and defueling and control the IDG cooling recirculation
system and the center-tank-to-wing-tank fuel transfer system.
The FLSCU comprises :
‐ fuel level sensors in the tanks to sense high, low, and overflow levels.
‐ a fuel temperature sensor to control the IDG cooling recirculation.
When fuel quantity in one wing tank goes below 750 kg (1 650 lb), the low-level sensor triggers the
LO LVL warning on ECAM.
