I think the lack of forces, especially in smaller, more agile plains, can introduce some motion sickness in experienced pilots who are familiar with, and their body expects, the forces they ought to be feeling when taking off, doing a roll, etc.

But still, until artificial gravity can be generated, this is the closest it will come for the vast majority of people.

There are some small/ultra light aircraft simulators that get pretty close, being able to rotate the cockpit left right up and down. Still, can't really simulate directional acceleration/deceleration with possibly short bumps like landing gear contacting the ground and similar.

But definitely, any pilot will tell you that feeling all the forces is actually big part of good piloting, as you can feel what the airplane is experiencing & act accordingly. I took a ride in some small planes (a 4 person two motor plane and a glider) as well as an advanced small plane simulator and really, the simulator was good but not really comparable.

Not to mention extreme cases like air racing or aerial acrobatics where the forces are so extreme that they might prevent the pilot from having enough strength to execute control input or possibly even make them black out.

Going to argue against that generally. Vestibular disorientation is a significant killer of pilots. In instrument flying, you specifically train to ignore those sensations. Fly the numbers, not the feelings.

Yep, that's a good point - it can certainly also be a big problem in poor visibility or other cases where you get disoriented.

At Kennedy Space Center, the Space Shuttle simulation was pretty amazing. I believe the trick was to make us think we were sitting at rest at a 90 degree angle, when in fact it must have been less, such that when the shuttle did take off in the simulation the seat made an even higher angle (+ shaking). And the sudden lowering of the angle (when engine cuts off and we're supposed to float) was a pretty damn amazing illusion too. I definitely recommend it.

Yeah, I'd love to see a "behind the scenes" of that ride (it's entirely possible one exists, I haven't actually looked...)

I've ridden it several times, and while I intellectually understand how it must work, it's still super convincing.

For simracing and VR, a 6dof motion rig decreases motion sickness.
