acceleration due to gravity = Gm/r^2

From that formula, you could calculate the acceleration needed at different altitudes. I still don't understand how would I find the equation to model the airplane's position using sine waves. Any ideas?

As for your question, this is very tiny, even for a couple of kilometers of altitude change.

During the zero g portion of flight, the airplane is following a parabolic path (technically an elliptical path if you don't consider the earth to be flat), with a downwards acceleration of 1 g and near constant horizontal component of velocity.I still don't understand how would I find the equation to model the airplane's position using sine waves. Any ideas?
