This is going to be a can of worms!!
First if you use FMS to simply learn control imputs for basic training it will
serve you quite well. If you want to be a 3D pro the answer is not so much.
Just remember that flying a sim is like going to the field and putting a paper bag
over you head with a small square hole cut out for viewing.
What I did with FMS was fly lots of different plane and practice landing doing a clover leaf pattern( ie:
takeoff right to left, bank hard right, bank hard left, line up and do a touch and go left to right, and
keep repeating till you have formed a 4 leaf clover. Fly lots of different models they are all a little different.
And practice flying both ways inverted. Also do low slow inverted passes with the Airbus it looks quite funny
inverted with the landing gear.
And oh yeah. Stand up when your flying with your antena up. I feels more like the real thing.
Not as bad as you think. That goes for ANY sim. Anything more than basic orientation and controls is nothing more than a game. In FMS, you hit the ground, you wreck and have to reinitialize the plane. In G3, you wreck, you see pieces fly off and it makes pretty noises, and you have to reinitialize the plane. The only advantage the more expensive sims can do that FMS can't is channel 5 and 6. As for being realistic, and flight dynamics. There is not an airplane on the market that will fly exactly like it does in a sim ... any of them. Sims assume perfect Cg, latteral ballance and wing incidence. I played with G3 for a while until I saw that a turbine engine aircraft pulled to the left just like a combustion engine and prop. None of them are going to react like a real plane.
