The paperless route was started by Alaska Airlines which replaced flight manuals with Apple iPads. United is the first airline of its size in the U.S., to take the paperless trend one step beyond and eliminate the pilots' navigational charts in place of tablets on a permanent basis. A free app in the App Store, Jeppsen Mobile Flight Deck, helps keeps the UAL pilots on course. While American Airlines recently started offering the Samsung Galaxy Tab 10.1 to passengers, as we reported, the airline used the Apple iPad in the cockpit when testing for the FAA how safe using tablets in lieu of paper would be. It seems that the advantage of being first to market and offering a bigger selection of apps, has allowed Apple to dominate the tablet market in the sky just as it has back down on earth.
