I think that is for passengers during the critical phases (takeoff/landing) so that they are not distracted. A few airlines have switched over to digital maps for airports, since they offer some substantial advantages (less weight, more up to date, etc). If you want to have a look at one of these apps, its on the public app store (https://itunes.apple.com/de/app/lido-iroutemanual-aeronautical/id413078249?mt=8 https://itunes.apple.com/de/app/lido-iroutemanual-aeronautic...) - though I could not find a source that AA is using the LH Systems app (and if it was the source of the problem, I guess there would be several more stories about it. edit: Source: did some work for LH Systems, but not affiliated with them.
