The costs for day-by-day operation of an aircraft are a key business item for airlines and aircraft manufacturers. Also the cabin operation costs have to be optimized to stay competitive. One of the main advantages of Digital Cabin Logbook (DCL) is the standardized defect reporting. The cabin crew selects cabin defects from a standard defect catalogue, which is customized according to Cabin configuration. For selection of the location of a cabin defect, the use is guided via a graphic user interface.
