How do u weigh an aeroplane ?

Question

Suggest any method apart from weighing indiviual parts and adding them up !

Please suggest a feasible way to weigh an aeroplane

Answer 1

this is actually a three step process. three jacks are used one on the nose and one on each of the main landing gear. using three load cells,one each is placed between the jack and the jack pad. it is then lifted,a reading is taken and then set back down. this is done three times and the average weight is your weight of the aircraft.

the other is similar to how big rigs are weighed. a plane is pulled on to a scale. this is done three times as well.

Answer 2

Nothing in aviation is terribly feasible, but the best and most accurate way to weigh an aircraft would be to send it to an aircraft maintenence organisation. There they usually adhere to specific requirements on what can be included in the aircraft weight. But essentiailly, they place the aircraft on scale and take readings and do calculations to work out certified empty mass, arm (Centre of gravity position relative to a given datum) and moment.

I wouldn't attempt to use your usual bathroom scale however if you want a DIY solution!!

If you are just looking for a specific aircraft weight, refer to the weight and balance documents for that specific aircraft- the aircraft has to be weighed every five years (from where I am from), and this document is required in order for the aircaft to be legally airworthy.

Answer 3

The aeroplane complete with this engine weighed 78 pounds.
It will be the first aeroplane ever built of aluminum. It has been used in gas bags, but not in aeroplane work. It will take 500 pounds of aluminum, and the new ship wont weigh much more than half what the old one does. It will carry eight passengers.

Multiply the volume with the density of water (1000 kg/cu.m) - this will give you the mass of the aeroplane

Answer 4

same as anything else... you roll them on a big scales... the method is used to weigh huge trucks. all you need is a bigger platform so that all wheels of the plane can stand on it. the police now has mobile devices, where you can roll one wheel after the other onto and a clever computer tells you how much the whole thing weighs.

or when you are inside a hangar, you lift it with a crane, and measure the strain on the cable... use two slings around the wings, they are by definition capable of carrying the planes weight.

Answer 5

rghaviation is correct. The scales must be certified and in calibration, procedures followed correctly, calculations done correctly all by a qualified aircraft mechanic and log book entry made after which, if there is a change the weight and balance documents in the aircraft flight manual must be updated. a scale is placed under each landing gear wheel.

Answer 6

you have a weighing kit in every approved maintenance station
under the A/C, close to ldg gear , you'll find the lifting points, put a jack with the weighing pad under it and proceed according to the manual's instructions
do not forget to include arm lenght in calculations

Answer 7

It ins't too difficult as mentioned. The scale is rescessed into the concrete so all you do is measure each wheel and add up the values. Once you have that value established for the type you only need to add/subtract with payload, fuel, pax, etc.

Answer 8

He is pretty much correct. When we weight the C130, we use 6 scales, one for each tire. They are calibrated to be used that way.

For large aircraft, it is not feasible to have one large platform that all tires can sit on.

Answer 9

on highways trucks go to weigh stations...well at airports they have the same thing. when a cargo plane is ready to depart it goes onto a scale so they can figure out what the take off speed needs to be.

Answer 10

You "drive" it onto a set of scales.
Similar to a weigh bridge, but for planes.

It's not difficult!
