The ipad Air 1 uses the A7 CPU, it works fine in cool weather. But it may overheat in 95F+ ambient temps. So if you see a video problem on a hot day, don't panic. The controller still has control of your craft and you can bring it in with VLOS, assuming you're within VLOS. The RTH button will work fine if you can't see it. After the iPadAir cools down it will work good again. I have this issue with my iPad mini2 all the time, using the same A7 CPU. If it's really hot, I often fly from inside the car with the air conditioner running. Make sure you fly WITHOUT a case around the iPad, so it maximizes cooling.
