I would be absolutely astounded if the simulation didn't reasonably faithfully handle the inertia -
It sort of does.
But its very digital in responce ie you do the same thing 6 times in a row and the outcome will be the same. In a real aircraft do the same thing 6 times and you will get 6 slightly different results. Mainly due to the fact than an aircraft is flying in an analoge eviroment with a vast number of variables which the sim doesn't bother with for either they are to difficult to introduce or take to much computation time.
You have to learn to fly the sim after real flying. Alot of automatic responces in the aircraft play merry hell with the sim and you can end up over controlling. And vice versa some of the things you do in the sim won't have the desired effect in the aircraft. The sim is very much by numbers the aircraft more of a fluid control responce.
