Until recently, Electronic Flight Bags (EFBs) were typically thought of as large computer devices mounted in the cockpits of high-end jets and airliners. They usually relied on a permanent mounting fixture, and needed to be hard-wired into the aircraft’s electrical system. Once installed, these EFBs provided electronic charts, moving map displays and weather in the cockpit. While they could be adapted to general aviation aircraft, the costs usually outweighed the benefits, and they never really gained widespread popularity. During this time consumer electronics manufacturers sold more affordable, tablet-based computers that could be modified to serve as an EFB, but it took a lot of work on the pilot’s end to load software and string around wires in the cockpit.
