ATLANTA - Delta says the Surface tablets will save $13 million per year in fuel and other costs. Right now, each pilot carries a 38-pound flight bag with manuals and maps.
Other airlines have been buying Apple's iPad for that purpose.
Delta is testing the tablets on its Boeing 757s and 767s. Delta is hoping for Federal Aviation Administration approval next year to use them throughout the flight, and it hopes to have approval for all of its other planes by the end of next year.
One reason Delta picked a Microsoft device was that it's easier to give pilots separate sections for company and personal use, said Steve Dickson, Delta's senior vice president for flight operations.
Another reason for picking the Surface tablet is that Delta's training software also runs on the same Windows operating system as the tablets, reducing the need to redo that software for another device, Dickson said.
In August, Delta said its flight attendants will get Windows phones to process in-flight sales of food, better seats, and other items.
