Fuel quantity measurement, 737-800
Hello guys
I am wondering whether this is something specific to the fleet my company operates or if anyone has been exposed to this problem themselves.
On all flights on the 738 until now and on different specific planes I have noticed the same thing. During inflight fuel checks the FMS indicates that we will have a larger amount of fuel at our destination when we still have fuel in the centre tanks than when we do during the same fuel checks after the centre tank fuel is used.
On a typical sector of 4 hrs. the difference will be around 300 kgs.
It would seem that the measurement equipment in the centre fuel tank is less accurate than the main fuel tanks, causing a correction when the centre tank is empty.
Would anyone know the reason for this?
