I will be testing out my new Phantom 4 with the just released 9.7" iPad Pro. It's the same size and weight as the iPad Air 2. The screen is 25% brighter, and that should help outside. From initial side by side comparison of the screens, at full brightness outside on a very sunny day, the iPad Pro was noticeably more readable. That should help the on screen visuals when flying, without a sun shade. Apple says that the reflectivity of the screen is 40% less than the Air 2 as well.
