Most pilots love the iPad because it almost never crashes, making for an extremely reliable tool. But there is one sure-fire way to get your tablet to shut down–leave it on the glare shield.
The iPad, being almost completely black, will get extremely hot if left in direct sun. As a protective measure, the iPad will shut itself down and stay shut down until it cools off. This can be very frustrating if you reach for your approach chart right as you turn final, only to find a dead iPad.
In our experience, overheating is not an issue if you leave your iPad on the yoke, on your leg or on the floor. The only crash we’ve ever seen was when we left it on the glare shield during flight, in direct sun and with no airflow. The iPad would not turn on until after we landed.
Our suggestion–find a relatively cool place to secure your iPad during flight, and your tablet should perform flawlessly.
