Konde thank you ,
I know the OEB , but we didnt use a company route and besides here, there is a prediction .On the mentioned bug, there is no prediction.
But you never know its an Airbus may be it might have worked
By the way , i tried to modify the FOB.And it worked . So i confirm , Its blue and modifiable.
When you change it , it turns to /FF from /FF+FQ.
E.g. : Before 3.1/FF+FQ you enter "7.9 " it turns 7.9/FF
Meaning , the fms starts believing what you tell , and disregards the FQ.
Basically when you put in an FOB , the FMS then calculates the new Dest and Alternate EFOB accroding to it.
Everything make sense and logical at this point.
The problem here is, after the calculation EFOB is greater then the FOB.
