The FQI system has these components:
-
the Fuel Quantity Indicating Computer (FQIC) 3QT
-
the On-Board Replaceable Module (OBRM)
-
the fuel probes 21QT1(21QT2) thru 34QT1(34QT2), 35QT thru 39QT.
-
the cadensicons 19QT1(19QT2), 20QT
-
the preselector 5QT
-
the multi-tank indicator 6QT.
The FQIC controls the FQI system. The OBRM is attached to the FQIC and contains the software to operate the FQIC. A set of fuel probes are installed in each fuel tank. Each fuel probe has an electrical capacitance value which changes in relation to the change in depth of the fuel in its tank. The FQIC regularly measures the electrical capacitance values of all the fuel probes. It then uses each set of probe capacitance values to find the volume of fuel in a tank. The fuel probes 22QT1(22QT2) and 33QT1(33QT2) have diodes that are used to calculate the temperature of the fuel adjacent to them. The FQIC regularly monitors these diodes and uses the voltage drop across them to calculate the fuel temperature. The fuel temperature for each wing tank cell is shown on the System Display (SD) FUEL page of the ECAM.
