One quart is equal to 32 fluid ounces. A quart is the equivalent of 2 pints, and each pint has 2 cups. One cup is equal to 8 fluid ounces. Therefore, 1 quart is equal to 4 cups, and 4 cups multiplied by 8 fluid ounces is 32 fluid ounces.
Glenn Research Center. This is a computer drawing of the fuel system of the Wright brothers' 1903 aircraft engine. This engine powered the first, heavier than air, self-propelled, maneuverable, piloted aircraft; the Wright 1903 Flyer at Kitty Hawk, North Carolina, in December, 1903.To generate thrust for their aircraft, the brothers used twin, counter-rotating propellers at the rear of the aircraft.ngine Fuel System Glenn Research Center This is a computer drawing of the fuel system of the Wright brothers' 1903 aircraft engine.
When aeronautics was in its early years people with daring took on as much fuel as they could to fly over great distances with quite inefficient engines. I suppose the answer is: an airplane can hold as much fuel as the maximum take-off weight for that particular plane is. Of course, getting extra fuel tanks in there, and connecting them to the intake is huge work, and I don't think people much do long-distance flying with small planes these days, since all the records have been set, even for a non-refuel flight across the world.
