You already know that it is important to do a weight and balance calculation prior to any flight to make sure you don’t put too much weight in the airplane and that the center of gravity is within the published limits. But you may not realize that you should do at least two weight and balance calculations.
As you burn off fuel during your flight the weight clearly is reduced. A reduction in weight is only going to bring you further under the max gross weight and is not going to affect the safety of your flight.
