One problem with a simulator is that the pilot does not get any normal acceleration cues to his body (ie. g). If you have an aircraft that needs to fly at more than 30 deg of bank and the manoeuvre stability is such that you need to trim into the turn (Phenom and Nimrod), the pilot will use g cues, albeit subconsciously, when flying the task. Therefore, training for these tasks really needs to be flown in the aeroplane and not just in the simulator.
