Ehem, tecpilot.
Look at Kamov HB-XKE, it has a huge bubble window on the left side. Below it, they have a little instrument panel for TQ and so on. They fly VR AND use the mirrors. Whatever works best in that particular moment.
I made the experience that old pilots rather use mirrors and young pilot VR.
What I do not understand is, that you can convert the AS350 to be flown from the left side with a bubble window. But have only seen one of them in Alaska. Never in Europe. Where is the problem?
