American airline Delta is to equip 11,000 of its pilots with Microsoft Surface 2 tablets, in a bid to eliminate paper resources.
The recently launched Surface 2, which runs the Windows RT 8.1 platform, will provide crews with key charts and navigation tools via a customised app.
The tablets will replace the 17kg (2st 10lb) flight bags currently carried by pilots, reducing fuel consumption.
The company expects all its cockpits to be paperless by the end of 2014.
Delta had previously tested Apple iPads as potential Electronic Flight Bags (EFB), but has recently embraced Microsoft devices.
