Put an experienced pilot in any airplane and chances are they will be able to fly it, albeit fairly roughly. That is because all airplanes follow the same laws of aerodynamics and gravity: pull back, they go up, push forward they go down, chop the wings off and they go down very fast. But we are currently flying in the ‘fourth generation’ of commercial aircraft, which means beyond the base aerodynamic rules of science, there are some significant systems inside helping them fly.
So, just how different are Boeing and Airbus?
