Google / Wikipedia tell me that the the 4 main forces involved are thrust, weight, drag and lift. Makes perfect sense. When thrust and drag are equal the plane has constant velocity. When weight and lift are equal the plane is in level flight. Ignoring the complexities of vectors, etc.

So, is my first step to put some values into those?

How much does a plane weigh?

Or what the forces / accelerations involved are, or how to calculate backwards to sensible starting figures?

Is there somewhere that has already done this work? Even if I need to simplify it?
