Flight Modeling vs. Flight Handling.

[namroob]

It's not just handling either. When flying a real aeroplane your senses are assaulted by noise, constantly changing g-forces, constantly changing visual stimuli over your whole visual field (as opposed to a screen in front of you), and so on. It's a far more intense experience compared with flying a PC sim, especially aerobatics. Even the weight of a helmet takes some getting used to. And the controls of anything from a light twin up can be physically far heavier than PC controls, requiring a bit of muscle to move.
