Hi Heatblur
When the QTY SEL switch is on FEED (center position) the fuel weight indicated on the FUEL PANEL is 1800 on the left and 1800 on the right.
It should display 1500 on the left and 1600 on the right.
When the QTY SEL switch is on EXT (down position) the fuel weight indicated on the FUEL PANEL is 2000 on the left and 2000 on the right.
It should display 1800 on the left and 1800 on the right.
When the QTY SEL switch is on WING (up position) the fuel weight indicated on the FUEL PANEL is 2100 on the left and 2100 on the right.
It should display 2000 on the left and 2000 on the right.
