Is Plane lighter going west than going east?
I would expect a plane to be lighter after subtracting out wind velocity and centrifugal force effects, when going westward than when it is going eastward. It may be that the centrifugal and centripetal effect in the opposite direction conceals this but perhaps the computer collection of data on an airplane might reveal it??
I assume measurements of wind velocity can be constantly recorded by a computer on the plane so that it would be easy to tell what part of the also recorded lift is due to the wind velocity and what is due to some other factors including the centrifugal force etc..
By centrifugal force etc I mean that when the plane takes off in the direction the earth is spinning its total velocity would be this roughly (.465)cos(lat)km per second plus the velocity of the plane etc and in so far as this exceeds v where v^2/r=(6.6)(10^-11)mM/mr^2 about there should be a tendency to follow an elliptical orbit than a purely circular orbit etc which would in effect add to the lift. The reverse effect also precisely calculable, would occur in going in the westward direction.
Are such calculations made and such measurements stored and if so what do they show?
