I suffer a lot from motion sickness using VR. I can play games where I'm standing still (Moss, Beat Saber) but racing simulators make me feel sick.
Guess I'll be in trouble if somehow we end up using VR/XR all the time.

1. using a very strong vignette (like looking through binoculars) to preserve a fixed frame of reference, and then gradually adjusting the vignette to obscure a smaller and smaller % of the FOV.
2. when using a joystick to move the camera/character, only move forward and rotate to turn, marching in place any time you move forward (so you if you would normally strafe or move backwards, rotate first instead and then move forward).
3. use joystick movement for no longer than a couple of seconds and then stop and let your body calm, then move forward a couple seconds, repeat, stop any time you even begin to feel any nausea and take the device off and then come back after 20 minutes.
With these sorts of accommodations, a large percentage of people who get nauseous in VR can overcome it and end up with zero nausea as long as camera movement is fixed or its controlled my player input.
I trained myself on Skyrim VR with those comfort settings and I was totally fine after a couple of days (whereas before I couldn't use joystick movement for more than about 3 minutes before intense nausea kicked in).
Your friend having flown real planes probably makes him even more sensitive to sim sickness because his vestibular system has been trained on motion from actual flights, meaning it can perceive the mismatch in the sim much more acutely.
