But my friend , it is not because a pilot raised a snag that you have to reset something or try to fix something ... maybe there is no fault , simply !
I think thats a problem with many Engineers nowadays ...
You get a FUEL QTY LOW msg , first thing to look at , is the quantity of the remaining fuel in the tanks (common sense !!!) ... then the Manufacturer , is this case , to help you , created something called the MAT : Maintenance Access Terminal , use it !
Check the IFDE , PRESENT LEG FAULT , etc ... until you find something in the right ATA and then if it is necessary ... the FIM , you know , the Flight Information Manual
Anyway , all i just said is the basic way of working ... normally !
