Sometimes in other games like X-plane or FS2 it’s quite nice to just be able to sit down and fly purely using the motion controllers, there’s various ways of doing it for the actual flight controls from physically grabbing the controls, using the tilt angle of the hand controllers, or just using the analogue sticks for flight surface control. Overall I prefer using the HOTAS etc and then just grab the controller to interact with cockpit for items you haven’t bound, but it’s good to have options.
Ideal would be hand tracking so that as you let go of the stick your hand just becomes tracked and you can reach for what you want. Obviously a glove with haptics would be another level on top.
The Quest 2 has pretty decent hand tracking, and there have been other options around too like Leap Motion… shouldn’t be too hard to integrate if they wished.
