How to adjust the center of gravity of an aircraft if not level when being weighed?
I drew in the approximate location of the screws used to hold a level while leveling the Cessna Cardinal for weighing.


When my plane was weighed, they had to lower the nose by deflating the nose strut some, and raise the main gear, to get the aircraft to the level position indicated by the manual, with a level across the leveling screws on the side of the fuselage. I don't know that there is a procedure to weigh it in a not-level position.
