I never realized how user friendly the 172 was. I weigh 200 pounds, and as pilot it was impossible to stay below max gross and have the plane out of limits regardless of the amount of fuel on board.
I started doing the weight and balance computations on the SR20A and it is very easy to have the center of gravity too far forward. You can even start a trip in CG limits but become out of limits as your fuel burns. For a plane that is trying to be the “citizens” plane they really need to do something about the loading complexity.
