My iPad Air shuts down after about ten minutes in the sun here in sunny Goofafornia...South Goofafornia. But that was sitting on the starboard sided seat with the screen up. I think it may be better with the screen at 180 degrees to the sun....hope so. I'm gonna use the iPad for secondary charts because I think ForeFlight is better than the SkyView secondary system I sometimes contemplate for the stbd side the panel.
Please give me any input about your set up you can. I obviously is innovative and effective.
