(b) Do the test given in Para. 3.B. (6) If the fault continues, get the MCDU print outs of the FQIS input parameters pages, that you got (recorded) in steps (1) and (3). (7) Compare the two sets of FQIS input parameters records (paper printouts) and look for a value or values that can cause the FQIs to fluctuate, for example: - compare fuel probe parameters (values - K, T, V, KA, KB, DENS, TEMP, PITCH and ROLL) with the others given on page 1 for similarity of the fuel conditions and ambient temperatures - compare fuel probe capacitance values with the value of the same probe in the opposite wing or group - look for blank indications (of related capacitance values) for a harness group. (8) If necessary, monitor the FQIS input parameters pages live. Look for an unusual or incorrect value, an intermittent value, or one that is seen to have unexplained fluctuations. ____ NOTE : The FQIS input parameter pages are automatically updated once every 5.5 seconds to let you see the operation of the system in real time. (9) Make an analysis from the input parameter results (records made in steps (1), (3), and from the MCDU screen direct in step (8)) with the steps (items) that follow: (a) If you are not sure of the quality of the aircraft fuel: _ 1 Defuel all the aircraft tanks (Ref. AMM TASK 28-25-00-650001). _ a Drain the remaining fuel from all the tanks to make sure that there is no water in the tanks (Ref. AMM TASK 28-2500-650-003) (and if applicable (Ref. AMM TASK 28-25-00-650005)). Do a check of the aircraft log to see that the microbiological contamination of the aircraft fuel tanks procedure has been complied with. If necessary, do (Ref. AMM TASK 28-11-00-600-004) (Ref. AMM TASK 28-11-00-600007). Refuel with fuel of the correct specification (Ref. AMM TASK 12-11-28-650-003) (Ref. AMM TASK 12-11-28-650-004). Do the test given in Para. 3.B.
