My belief:   Heat dissipation with = everything running is only good to 10,000 feet.   but if you are = running foreflight and basically just looking at a chart, the ipad isn't = doing much.   ....don't play hd videos above 10,000 = feet.

One more question.  The apple specs show = maximum operating altitude of 10,000 feet.  If there is a good = technical reason for this, it would seem rather limiting for = our en-route use.  The operating temperature is also kind of = pushing the upper limit when on the ground on hot summer = days.  The temperature issue can be somewhat controlled, but the = altitude exposure not so much.  Is this a CYA or other generic = limit?

Environmental requirements

  • Operating temperature: 32=B0 to 95=B0 F (0=B0 to = 35=B0 C)
  • Nonoperating temperature: -4=B0 to 113=B0 F (-20=B0 = to 45=B0 C)
  • Relative humidity: 5% to 95% = noncondensing
  • Maximum operating altitude: 10,000 feet (3000 = m)
