On the very few types I know, trying to fill the tanks to the brim gives varying results, mostly depending on the slope of the parking position, even if the selector panel is set to slightly above maximum capacity. At some point, the system will consider the tanks full, even if there may be a few 100kg missing from their nominal capacity. So planning a flight under the assumption of having the tanks filled to their maximum capacity is not always the smartest of ideas and might lead to scratching of heads when the fueller brings the receipt.
So: how about the RJ85, will it always accept fuel until the tanks are physically full, or does it show the same effect?
