Even two PA28s will be different as power and drag are so variable. How good is the engine, the prop?
You missed the intention of the original question. We are talking about idealized scenario where all components are brand new, where aircraft has no bugs, no dirt, where engine parameters are well known, etc. Clearly he is not going to get it from this limited and insufficient list of parameters but it can be done, Boeing, Airbus and other developers can pre-calculate aircraft critical (critical for marketing) parameters (like speed, range) with 1% accuracy, this sort of accuracy is expected in some branches of aviation. It takes a lot more effort than throwing some numbers into a mathematical formula but it can be done.
