Overheating and Summer (SBFT)

Overheating of mobile electronic devices, such as a phone, iPad/Tablet, etc., is caused by the circuits getting to hot if the device is exposed to high outside temperatures over a long period of time. Overheating can or may cause fire, damage to the aircraft or injury to yourself. In most cases, overheating of the electronics and avionics in General Aviation (GA) aircraft is unavoidable.

You are also using an iPad or Tablet with either ForeFlight or any other mobile aviation navigation app. It is late afternoon and you are ready to fly home.

A few minutes after departure the aircraft's Garmin 430 screen has lines, and is blacking out, do to overheating.
