TW, yup, the cost being the only major hurdle.
Cynical, completely incorrect perception of the issue.
Used to get up for an RAAF cadet course to give their first mass brief.
First question.
"Who here uses MS Flight Sim?"
Three quarters of the hands go up.
"Well STOP USING IT AS OF NOW!"
The issue (besides people thinking "with you" is an acceptable form of Australian phraseology, which it IS NOT unless you're a visiting American, hint hint, nudge nudge) is that unsupervised, young un's will watch the instruments like hawks, neglecting the visual attitude. You get a half decent visual (fixed base included) trainer with matching decent visuals and you sit beside the student doing exactly the same ad if you were in the aircraft. Piece of puss!
The ideal way to utilise this marvellous tool is to perform the deired sequence, correcting mistakes and introducing procedures and flows without the added distraction of motion and then duplicate the sequence in flight. Student already has 90% of the lesson anticipated and maximises their time in the air. Any instructor worth their salt knows the aircraft in flight is a terrible learning environment.
Can't see how at most every second flight in a ground trainer is going to make vertigo worse.
Bundy, woulda said the same years ago. You get a good graphic accelerator, wrap around screens and expanded location specific add ons and the fidelity is spectacular. You even experince some of the motion illusions.
