Delta’s getting on board with tablet technology. The company announced that it will be replacing the reference manuals and maps used by their pilot’s with Microsoft’s Surface 2 tablets, allowing them real-time access to tools and resources. It’s all part of an effort to ditch lengthy paper manuals and flight charts and will save the company about $13 million annually. Delta will start making the switch later this year, first on Boeing 757s and 767s. They plan to go 100% paperless by the end of 2014.
