Abstract: A portable, hand-held computer functions as an intermediary between a database server and individual aircraft when the aircraft cannot be connected to the database server. By virtue of being portable and being locally linked (over time) to different aircraft, the intermediary computing device can provide the data upload validation and auditing for accurate billing of database usage for a flight database provided from the server. This ensures that each aircraft which receives an uploaded database is entitled to receive the upload based on a paid license. As a result, billing by the database vendor is based on usage. Licensing and data authentication is mediated by the intermediary computing device.

Abstract: An onboard system establishes a first-EFB connection between a first electronic flight bag (EFB) and an aircraft interface device (AID), and establishes a first-EFB session between the first EFB and a flight management computer (FMC) based on a session identifier for the first EFB. The first-EFB connection is associated with a first-EFB connection identifier for the first EFB, and the first-EFB session is established over the first-EFB connection in accordance with the first-EFB connection identifier. The onboard system establishes a second-EFB connection between a second EFB and the AID, and establishes a second-EFB session between the second EFB and the FMC based on a session identifier for the second EFB. The second-EFB connection is associated with a second-EFB connection identifier for the second EFB, and the second-EFB session is established over the second-EFB connection in accordance with the second-EFB connection identifier.
