**Skylegs Electronic Flight Bag app for aircraft operators** This app is made with the purpose of having a paperless cockpit. Operator, Aircraft and Flight documentation is managed from a central online application by the EFB administrator and send to different Apple devices. Pilots can download new versions, annotate and sign before the flight. These documents are stored offline on the device to be used during flight. Operators can connect iPad devices to the online central platform via a unique token. Most of the time this is done by a dedicated person, the EFB administrator. This person can keep watch of app version, iOS version and battery status in one overview together with a list of the documents stored on the device. Our application in combination with the iPad EFB gives the operator the possibility to get paperless cockpit flying certified with their local CAA under different kinds of regulations like EASA or FAA. **Important** This app does not function without the central online Skylegs platform and a Skylegs 'Concorde' operator account with the Advanced Document Control module included.
