We have over 3000 iPads at our company. We're the first to get FAA approval. Requiresd cold soaking and depressurization testing and comparability testing for apps. . We can not load any programs that are not approved. Using it as an FAA approved flight bag limits its capability. As the term hints to it replaces the flight bag. Meaning the jepp charts and AOM/FOM only. During flight there are only 2 authorized apps allowed to be open. One coe nepps the other for company manuals. There are a few custom company designed programs. The company can monitor the status of our jepp and manual updates and we get hate mail when they are not up to date in our company email. We can not update the programs until the new update is tested and approved. That goes for jepp view which is what we use. It is slightly tailored for us. Use of any GPS functions in the charting is prohibited in all phases. We use the iPad 2 because that is what the year long testing was done on. 2 are required along with a backup battery. Although I usually can go a full 7 days without even needing to charge it. . When it is used to simply replace the paper jepp chart it isn't on that long during the flight. So having said that I get "free jepp charts for my plane":). I enable the ownship on it in my IVP. I also have my personal iPad 3 that has foreflight on it. I find it nice for inflight weather planning on our company planes. Nice to have onboard wifi. I used it for navigation purposes one time when my off GPS database was out of date and didn't have have any Canadian data on my IVP. So I filed by Class I navigation to stay legal. I would never count on it for navigational purposes primarily. I do fly with 2 iPads in my plane and the citation X probably logging 700-800 hrs per year combined. So I have some experience basis for my opinions. There are records of violations in the DC area due to navigational errors due to iPad reliance. The FAA is t too forgiving if your excuse is my iPad led me astray. Typing and grammar errors courtesy of Siri and the iPhone.

If its good enough for American Airlines then I'm probably ok too.
Now that is an example of a content free statement. Lets review what you actually know.
An article in a non-technical publication states that an airline is using iPads as "electronic flight bags" and publishes a picture of a person dressed as a pilot sitting in an airline cockpit (or its mockup) holding up an iPad. What does that tell you about your using an iPad for in-flight navigation in your Lancair? Absolutely nothing.
Do you know if the airlines are just clipping the iPads where the used to clip approach plates or are they mounting them on a purpose designed mount with an integrated cooling fan or maybe even a thermoelectric cooler?
Are they using a stock application or do they have a custom application that takes over everything, does not allow anything else to run to reduce power consumption & increase reliability and starts giving warnings of impending shutdown well in advance?
Depending upon how much support they got from Apple, they may even have access to advanced capabilities like clock throttling, shutting down extraneous hardware and other advanced means to reduce power consumption that Apple may not have made available to the general development community. Do you know if that is the case?
Did they just buy 8,000 iPads and issue them to their pilots or did they buy 16,000, 32,000 or even 80,000 iPads and screen them for performance in extreme conditions and keep only the 8,000 "unmodified" units that were actually screened to perform outside the design specification?
The article did not touch any of those issues and you look rather silly advocating that anyone can "use an iPad just like the airlines do" without knowing what the airline are actually doing. Which leads to your comment:
Why don't you send your estimate of reliability to AA for a comment? Unless you know more than the airline does...
There is no reason to comment to the airline because we do not know what they are doing. We only know what you are proposing and that is why all the comments and criticisms of your plan are directed at you.
Finally, here's something we do know. The airline's environment is an air conditioned cockpit with much less exposure to the sun than you do in the L-IV or 3 series. When it comes to a piece of hardware shutting down due to heat, those differences alone make a huge difference. Heat also accelerates aging. As a rule of thumb, each 10C increase in temperature reduces the life expectancy of electronics components by half.
Until you know all these details and are able to replicate what the airline is doing, you are just comparing apples to paperweights (pun intended).

Hamid
