An onboard digital computer (18) positioned within the in-flight entertainment system of a passenger aircraft (10), which computer (18) contains application programs to perform automatic cyclical interrogation of system components(26, 28), detect faults in system components (26, 28), provide a graphical user interface (100) for airline personnel to enter into and display information from the system, maintain a stored register of inoperable, failed, or otherwise noteworthy problems with respect to any component of the in-flight entertainment system, the provisioning of the passenger cabin, and other facilities within the cabin such as the galley and its components, and lavatories and their components, whereby faults found are then transmitted, via a communication link from the aircraft (10) to one or more ground stations (38, 40, 47), at pre-determined times, to inform appropriate ground personnel of the faults, and thereby permit the ground personnel to assemble appropriate repair tools, replacement parts, and the number and type of personnel needed to efficiently address, repair or replace problematic components at the earliest opportunity available once the aircraft (10) reaches the ground. |
