Sorry Russell. Got news for you and it's all baaad. Ask Mike, he's flown the real 777 sim.
I once had the company of the Chief Trainer for Boeing on a flight into Seattle, and when we discussed Microsoft Flight Simulator he told me the alarming news that if I could land a 747 in flight simulator I could do it in real life. I just can’t wait for all the flight crew to come down with food poisoning….
