Aircraft come in many sizes and weights. The smallest are sport planes carrying only the pilot and weighing as low as 1,000 pounds or less. Mid size airliners are around 300,000 pounds and fighter jets are around 40,000 pounds. The largest current aircraft is the A 380 which takes off at 1,200,000 pounds.
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.
Stand on a scale. Figure out how much you weigh. Then pick up the airplane and stand on the scale. Subtract how much you originally weighed, and that is the weight of the airplane.
a bunch.
A paper airplane? A 747? Cessna?
It usually has to weigh below 60 pounds, but check with the airline for a definite answer
They can weigh from 3,000 pounds all the way up to over 800,000 pounds.
100 pounds
Most people are surprised how much airplanes weigh, and engines too. Reciprocating engines typically weigh 1 pound per HP. Big jet engines weigh 0.2 pounds per HP or so and they typically weigh from one ton to several tons. Here a simulator for designing your own engine: http://www.grc.nasa.gov/WWW/K-12/airplane/ngnsim.htm
Fully loaded 875,000 lbs or 396,890 kg.
150lbs. So it can be safely flown by a airplane.
The weight of an airplane can vary widely depending on its size and model. Generally, commercial airplanes can weigh anywhere from 50,000 to 450,000 kilograms, which is equivalent to 50,000,000 to 450,000,000 grams.
That depends on the airplane. Corporate jets weigh from around 10,000 to almost 80,000lbs. Jet fighters are usually around 30,000 to 70,000lbs. Airliners are between 100,000 and 1.3 million pounds.
