Add weight, say 20 pounds at a time, and make a test flight. Whatever you use for weight should be secured to prevent any shifting of position. Also, realize that weight added to the seat and secured with seat belts is not distributed the same as a passenger. A passenger's leg weight is forward of the seat and upper body weight is slightly aft of where your butt rests in the seat. Before you do any test flights, do the math on W&B to insure that, with the weight of a passenger, the C.G. stays within the envelope. Know what the mathematical limit for a passengers weight is and approach it with caution. Use the moment arm of the pilot to establish the moment arm of the passenger as they would be one and the same with a fixed seat position. Never allow whatever weight is used to shift rearward. An out of C.G. to the rear is the worst possible flight condition. IMHO, I would never do stall tests with a rear most C.G. without a parachute. I'd rather placard the aircraft to "prohibit stalls when carrying a passenger". Larry Flesner
