I have read the story. . . and it was only aircraft that were head toward Ronald Reagan International Airport in Orange County California that attempted to load those charts for that airport that crashed the FlightDeck App for American Airlines. The only affect it had on all of their 737 fleet was that every single plane in their fleet had that database in them, not that their FlightDeck apps crashed. . . but that it could have, had they attempted to load that doubled chart. Since the vast majority of American Airlines fleet does not land at Ronald Reagan international Airport, they were not affected by the glitch. You don't know what you are talking about.
The rest of the fleet merely had to download an updated version of the database which Jeppson had to correct which did not include the doubled chart for RRIA. Problem solved.
None of that was an update problem with the Apple iPad, the iOS 8.3 update, or even the FlightDeck software. It had to do with some worker somewhere who assembles the database putting in two version of the chart for RRIA. . . perhaps one with a minor change and one without.
You are building a mountain out of a molehill. . . and really, really wanting to blame Apple for it.
There are several other stories claiming the enire AA 737 fleet. Star Sparky claimed 5 planes only, then it was a dozen then several dozen now I see stories claiming 70 planes plus and then the entire 737 fleet on AA.
So lets go with 50 plus. and being a 737 holds around 200. then it's safe to assume that somewhere between 2500 and 10,000 passengers were affected. Yeah sure just a little tiny problem hahahahah.
