I haven't a favorite solution. All good solutions are welcome.
I have start flying flight simulators with Microsoft FS4. The simulators have developed a lot, but one problem stay until today: the limited view. It is still heavy to change the view fast to handle all the cockpit elements. I tested Track IR, but this was bad for me. Then I have installed and used EZDOC. This is a useable solution.
If VR works better then Track IR than it will become my solution.
I also will test eye-tracking. Maybe speech recognition can help to handle a complex cockpit. This is like you give voice command to the copilot.
