Prevent iPad overheating issues in the airplane this summer

Based on iPad Pilot News reader surveys over the years, most pilots have had the iPad shut down at least once in flight due to overheating. This is by far the most common problem reported by pilots when flying with an iPad, but it can be prevented with some planning and preparation.

Apple lists the iPad’s normal operating range as 32° —95° F. The recommended temperature for storing your iPad is -4° —113° F. While there are reports of the iPad shutting down when operating in environments well below freezing, the most likely result will be lagging as you interact with the touchscreen (tip: when operating in cold environments, plug it into a charger and use a case to help generate and retain heat).

The more likely scenario when operating at the extreme ends of the temperature operating range is overheating, which will lead to the iPad entering a thermal protection mode where it will become completely unusable until the device’s internal temperature is reduced. The primary reason is to protect the enclosed lithium-polymer battery (bad things can happen if they get too hot).

The first scenario can happen when you’re flying in a low-wing airplane en route at altitude with the iPad secured in a kneeboard on your lap. You’re in VFR conditions in sunny weather, but the iPad is out of direct sunlight.

Then, you make a turn over a waypoint, and the sun begins to shine directly on your iPad’s dark screen without you noticing. Even though the ambient temperature may be well below the 95° F limit, the iPad’s internal temperature will quickly elevate and soon display the overheat warning.

The other likely scenario in which your iPad can unexpectedly overheat is after shutting the engine down on the ramp on a hot summer day. Before the iPad, many pilots would set their paper charts or kneeboard on the glare shield to get them out of the way. New iPad users might inadvertently do the same thing out of habit.

As we all know, the temperature inside the cabin will quickly rise after you shut the door, again putting the iPad in a vulnerable state for potential overheating. Make it a habit to take your iPad with you after shutdown or store it in a protected part of the airplane to ensure a timely departure when you return.

Your iPad becomes completely unusable when it overheats and will display a temperature warning on the screen. Your only option is to get it to a cooler environment and lower the internal temperature. Remove it from direct sunlight and aim a few air vents if possible. If you had it in a kneeboard or case, remove these to aid the cooling process and remove it from any charging sources. Once the iPad’s temperature lowers, it will automatically switch back on—there’s nothing else you can do except keep it out of the sun.

If you’re a ForeFlight user, the app will detect this overheating situation and display an on-screen alert, giving you a little extra time to correct the situation and prevent a complete shutdown.

If you fly an airplane that has large windows and lets in a good deal of sunlight to the cabin, your best bet is to consider a yoke or suction cup RAM or Robust mount. These provide plenty of flexibility to pivot the iPad screen away from direct sunlight, and expose more of the front and rear surfaces of the iPad to ambient air for continuous cooling.

If a kneeboard is your only option and overheating is a concern, try raising the iPad slightly above the bottom of the kneeboard to create an open layer of air between it and the backside of the iPad. Many pilots report that adding a few pencils to accomplish this works well. It might not be the most polished solution, but it works! For a simpler kneeboard solution that does not restrict airflow, check out the MyClip kneeboard, which does not rely on a traditional rigid base to keep the iPad secure on your lap and allows for more airflow around the device.

You may also want to consider using small sunshades on your windows in flight to help reduce the intensity of the sunlight reaching your iPad. Good options here are the slap-on sun visors that cling to the windows on their own, or collapsible sunshades that provide more protection. Not only will they keep prevent your iPad from overheating, but they’ll also keep you cooler as well in cockpits with large windows.

Another consideration is to use the X-Naut Cooling Case along with your iPad. This mounting system features built-in fans to circulate cool air, specifically targeted at the iPad’s main hot spots to prevent it from overheating. The mount can be powered off of typical alkaline batteries or USB with a power bank or backup battery.

In addition to working with the RAM mount system, you can also turn it into a kneeboard with this accessory kit—perfect for cockpits with a bubble canopy where the iPad is exposed to direct sunlight. The X-Naut is available for the iPad Mini 1-5, iPad Mini 6, the iPad Air 1-2 and 9.7″, the iPad Pro 10.5”/10.2″/iPad Air 2019/iPad (7th Gen)  and the iPad Pro 11″/iPad Air 2020-2022″.

With a little preparation and some new habits, it’s easy to fly all summer long with an iPad. In fact, after a few early mistakes, we have not suffered an overheating problem in over a decade of flying.

    I have my iPad Mini 5 mounted into the dash with a Guardian mounting system and the optional Cooling fan in my 1946 Ercoupe. Have not had any overheating issues since I installed the mount except when I left the iPad in the mount after shutting down and leaving it exposed to the sun. A few minutes in the FBO refrigerator cured the overheat problem in about 5 minutes.
