Anyway, if we are being pedantic, I have always understood "weight" to be:
The force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity.
You will notice that there is no reference to "the force exerted on a body when in an aeroplane that is accelerating rapidly".
So:
- Mass is constant.
- Weight is constant (near as makes no difference) - unless you have a facility for inter-planetary travel.
- 'G' is a term used to refer to weight on earth.
- It is common, in aviation, to measure the forces accelerating a body in multplies of 'G'.
