Woow, thanks guys for the inputs.
Indeed, trying to sim those phenomenons like G loads will be way too hard and expensive. And to try to simulate G forces on your body, could even be harmfull and dangerous like mentioned.
Here the idea would be more like simulating a stimulus that would represent the G's (and not emulating G's hopefully lol).
I started thinking about this since the consequence of pulling G's would be an inflation of the suit. At least sitting in our rig, we should feel it.
When I learned aerobatics, I could feel the G's indeed when the instructor was flying the plane but when it's your turn, being concentrated on what U do, you don't realise it, it kinda becomes a second nature somehow...
I do have a functional g suit at home. And looking at it made me wonder how I could link it to the sim data output just for the fun. Combined with VR, might be a fun experience...
