Hi, Lately I’ve been trying to do regional flights in my Airbus A300-600 and when I load into a ramp I can load my cargo etc. But when I push back and start my engines my fuel which was originally at 70%, which is what I set it to before I loaded into the flight instantly goes straight to 11% fuel which can hardly get me a few NM out of the airport. I have tried many solutions to attempt to fix this problem but none of them have seemed to work. Any suggestions?
