Answer / bart rosenberg
At least two problems with the question. 1. It does not say
airplane, just plane. A plane in space is defined by three
points, and has no weight. 2. It says "scales", implying
that at least two scales are needed. Just use one scale.
Problem solved. Listen to what they say, not what you think
they mean.

Answer / ram
Well, if you know the thrust of the engines, and can
measure the acceleration of the aircraft, you can calculate
the mass of the plane.

Answer / john p. lesslar
If this refers to an actual airplane, use the force lift
equation: FL=CL(pv^2/2)A, where;
CL = the lift coefficient determined by the shape of the air
foil and angle of attack (can be determined by just
referring to an air foil performance curve)
p = density of air in regards to temperature (again, just
check the necessary table)
v = velocity at which the plane leaves the ground (do not
forget to convert to [ft/s] or [m/s])
A = area of the wing (chord X span)
Plug in the values and obtain FL. If you used [ft] for your
units, your answer will be in [lbf]. If you used [m], your
answer will yield [N].
To determine the mass [kg], just divide your answer in [m]
by 9.81[m/s^2]

Answer / arindom
First of all, I would ask for the specifications sheet of the aeroplane and the operation & maintenance manual. I'll take the answer from there. After all, the OEM is bound to have given it since you require the weight of the plane to design an airfield and ATC Tower

Add the weight of the individual components.. :-)

Answer / hari thapliyal
For a moving plane
1. find out the force with which gas is coming out. This is equal to the force which which plane is moving
2. find out acceleration of plan
3. use formula below.
m=f/a
weight=m*9.8

Two MIT math graduates bump into each other at Fairway on the upper west side. They hadn't seen each other in over 20 years. The first grad says to the second: "how have you been?" Second: "Great! I got married and I have three daughters now" First: "Really? how old are they?" Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.." First: "Right, ok.. oh wait.. hmmmm.., I still don't know" second: "Oh sorry, the oldest one just started to play the piano" First: "Wonderful! my oldest is the same age!" Problem: How old are the daughters?
