Update: American Airlines has confirmed that the problem was with a bad update to the Jepson app that added Ronald Reagan Airport map. The app provides maps of runways and more information to pilots. Until the app can be fixed, the airline has informed pilots of a workaround to prevent future delays.
Two years ago, American Airlines replaced the paper versions of its cockpit documents with iPad flight bags on all planes. At the time, the airline touted that the switch would both save money for the company and make the lives of pilots easier. This evening, however, more than several dozen American Airlines flights have been affected by an outage related to the app used by American Airlines pilots. Many flights have been delayed and passengers forced to exit the planes.
