The Cessna 182 Skylane originally had an empty weight of 1540 pounds and a gross of 2,550 for a useful load of 1010 pounds. With the addition equipment to make it more practical as well much like having four passengers on board while flying, the aircraft lost 50-75 lbs from its total weight capacity (useful). However by 1962 this changed when Gross Weight went up 100 lb and Useful Load got 80lb extra which allowed us to fill everything including 55 gallon fuel tanks with just 4 occupants per flight. The good news is that even at maximum Gross Weight performance was always still very efficient because they have substantially similar horsepower engines compared to today’s models!
