An electronic flight bag for use aboard an aircraft during flight is disclosed. The electronic flight bag includes an electronic storage device which acts as a container for storing various user-configurable flight-related objects, such as flight routes as defined by way-points, airport information that includes approach routes, associated fight charts or other desired charts, temporary flight restrictions, and weather information as well as any other user-defined data objects associated with the flight. For example, the electronic flight bag may be used in corporate aircraft and may include one or more data objects that relate to the corporate policies with respect to flights. The data objects may also include time-sensitive data and contain time flags that can be updated by way of a communication link during flight. In accordance with an important aspect of the invention, the data objects are user-configurable so that a user can include virtually all information that is relevant to a particular flight.
