Most planes in the world are not the big airliners, but smaller planes where single pilot operation is very frequent and many planes do not have a complex autopilot, but usually a 2 or 3 axis stabilization. Also in turbulent weather looking for 10 seconds at a screen can induce motion sickness even to seasoned pilots. We have to do that for map checks and calculations, not a pleasure.
Huh, I wonder if they can use a measurement to adjust the refresh rate based on turbulence. I think they did this for the space shuttle experiencing vibrations to make a screen readable.
It is not the refresh rate, it's the fact that you are looking at a screen that is not moving so much while the airplane and you body is shaking; your internal sensors are telling you are moving, the eyes do not correlate the information, you get motion sickness. I had this problem in my first 50 hours of flying, sometimes even after 100 hours.
