Abstract

The Ethernet-based cabin system control function of the B777-300 aircraft intermittently occurred during operation. This defect may be caused by the installation of a new system and changes in configuration, but it occurred intermittently during operation, but it caused a lot of inconvenience to passengers and crews because it occurred continuously. The defect was reported to the aircraft manufacturer and the system manufacturer and continuous review measures were requested, but a series of repetitive problems were not resolved. Therefore, as the subject of operating the aircraft, various experimental attempts were made to resolve the defect of the aircraft cabin system control, and the post-flight operation results were analyzed. As a result, it was confirmed that the defect was resolved through one of the various test operations. In this paper, an experimental method for resolving defects that were not discovered during the system development test, evaluation, and verification process of the aircraft and system manufacturers and occurred during aircraft operation was introduced, and problems were raised regarding the follow-up processing of the evaluation and verification of the system manufacturer and the aircraft manufacturer.
