I am flying the Business Missions in Concorde at the moment, and there seems to be a problem with the amount of fuel that is shown in the Flight Logger. Concorde has a full fuel load of approx 211000lbs of fuel however the logger only shows 159000lbs, this causes a problem when the fuel in the logger runs out, the aircraft is still capable of flight for quite a while, but the logger shows a runtime error and disconnects, this is a real problem as some of the flight legs are 4000nm plus and you have to be ecomomical with both speed and altitude to achieve the required distance. has anyboby any ideas?.
