hallo friends,I made an XML gauge "Fuel Quantity" in kilograms for my md80 panel. All displays (L main, R main, C main, Total Fuel Quantity and Total Gross Weight)in normal mode are OK.I want to have other two options like the real:ZFW and SELF TEST......but I don't know what I have to write in the strings to have displayed right value,for Zero Fuel Weight: Total Weight,kg - Total Fuel Quantity,kg in kilogramsfor Self Test: (Total Weight,kg - Total Fuel Quantity,kg) + 4500 kilograms ...somebody can help me?Kind RegardsRoby

Don't get me started on FS fuel - it's driving me up the wall.. :)I've just found out thatFUEL_SELECTOR_LEFTFUEL_SELECTOR_LEFT_AUXdon't do what you would think is logical. Switching the tank to AUX does indeed take fuel from that tank but FUEL_SELECTOR_LEFT doesn't take fuel from left main but from ALL left tanks - starting at the aux first. Frustration!Try something like:%ZERO FUEL WT -> %((A:TOTAL WEIGHT, KG) (A:FUEL TOTAL QUANTITY WEIGHT, KG) -)%!7d! KGand %TEST -> %(4500 (A:TOTAL WEIGHT, KG) (A:FUEL TOTAL QUANTITY WEIGHT, KG) - + )%!7d! KG
