Wouldn't a Win10 laptop do the job? And, while I don't really know, the early complaints I heard about Win10 was that it was designed too much for touch screens. That implied to me that there was a way to get information from a desktop touch screen back to the processor. Of course I could be mistaken.
Last night, after posting I roamed around the internet a bit, and found a few screens that seemed to be designed for outdoor, touch screen use, and having a nit value around (I think) 1500.
In my first reply to the OP, I suggested some 2-in-1 Win10 laptop/tablets, so yes, I agree that could be an option.
In your previous reply, you mentioned "external monitor via HDMI". I didn't think HDMI-connected touchscreen monitors existed, which is why I said you'd lose the touchscreen capability. I did a little Googling and am still not clear on what connection methods are supported, but I did figure out that yes, external touchscreens can be had. That still seems like an expensive and kludgy solution to me, as you'd have to pay for both a laptop and a separate monitor (which may require a 12V DC > 120V AC power adapter), then have some place for both of them to live in the plane. It will not be trivial to figure out an elegant solution with those components.
