Hello!
At one particular destination of our airline we always have a fuel difference of over 100kg between the amount re-fueled counted by the fuel truck (in liters) and the amount calculated by subtracting fuel remaining before refueling from ramp fuel after refueling.
This problem always happens at the same airport, on all aircraft. Compared to other airports, such a calculation gives an average difference of 30 kilograms.
The company is loosing a lot of money on this (3 times refueling - 330kg a day, 10 tons a month!)
We tried checking the fuel truck meters set to zero before refueling and the total meters differences but still get this difference every single time!
Any ideas what could be the problem?
The guys are either cheating or have a faulty equipment.
But if they are cheating how do they do it?
Regards!
