we've definitely thought about that! the force-feedback fly by wire makes it really easy to replicate the feel of flying the real thing very well. What you see outside though will be fixed, so maybe for instrument training it would be good, though I'm not sure about using the actual plane vs recreating the cockpit in an indoor simulator
My aviation major roommates in college drilled for their upcoming flights with, I kid you not, a large poster depicting their instrument panel taped to the wall of our quad and a folding chair. Training does not require VR-like immersion to be supremely valuable. :)
Especially when it comes to practicing radio calls, it's the repetition that breeds competence and therefore confidence.
