Basically, the Microsoft Surface 2 tablets have picked up Federal Aviation Administration (FAA) authorization for Class 1 or 2 EFB needs for all phases of flight, where the authorization process saw the Surface 2 tablet go through rigorous environmental and situational testing. Of course, there is no hard and fast rule here as airlines are still obligated to define their specific use requirements with the FAA as well as to throw in request specific device approval, which is why the FAA-approved Surface 2 tablet should keep plenty of Delta pilots happy.
This FAA authorization would include all phases of flight, allowing airlines to plan the incorporation of Surface 2 tablets with confidence into use within the cockpit instead of looking at it as a simple document readers. What do you think
