Airspeed created the topic: No change to existing load
Question 16 of the final test in the performance book has one of those, what is the min amount of fuel ballast to be added to keep the plane in balance throughout the flight, if there is no change to the existing load.
I can see where the answer comes from and the use of adding the weight to the nose, up to the ZFW, but isn't adding weight to the nose changing the existing load?
