I lead nobody astray.   But I suspect you might be optimistic about the =
reality of the label of "certified" in day to day use. It's no solution =
to potential failure.  Having electronics subjected to a battery of =
lightning and water tests has no bearing on whether they will or will =
not fail.  They still fail. And they fail without being subjected to =
lightning and water too.   Many Garmins go back to the shop for chips, =
buttons, screens, knobs, memory and other failures.  You can't send one =
back unless you shell out more than three iPads!   How economical is =
that especially when you look at the cost of deriving that model and =
delivering it to the panel?

Almost every high-cost piece of certified equipment I've owned has =
failed or required expensive factory repairs or an expensive warranty to =
backstop potential repairs. There aren't many certified manufacturers =
that give you a warranty much past the burn in period are there?   =
Certified boxes fail and sometimes they aren't even in sunlight when =
they fail.  Cheltons fail, Avidynes fail, Garmins fail.  They all fail.  =
You are making a silly argument suggesting iPad can't be used in =
sunlight.  In the same extreme sunlight, I will get my face, arm and =
lips burned.  It is simply a matter of keeping temps down in a =
reasonable range and out of direct sunlight and that goes for this pilot =
too.   Suggesting an iPad "predictably fails" is no different than any =
other device that exceeds the operating specs. But suggesting they =
aren't for use in the cockpit is really over the top Colyn.   Probably =
hundreds of thousands are in use every day in sunlight and they continue =
to provide the airlines and this pilot much more information at a small =
fraction of the cost of the  "certified" devices.  And, they are better. =
  Having a second in the bag is an affordable and easy backup.  =20

These boxes and iPads both have a place.  One costs an incredible amount =
and can't be updated easily and the other comes off the shelf, is =
inexpensive to own and duplicate and=85is used by the airlines.  Go =
figure.  An uncertified iPad providing guidance in a certified jet.  Who =
would have thought?

If you have stats that show Garmins or any other brand have an =
economically better failure rate than consumer electronics like the iPad =
I'd like to see it. I'm betting if you double up on the iPad for an =
extra $300-$400 your panel device loses in all categories of reliability =
and usefulness.     I could be wrong.
