The Jeppesen FliteLog file is a proprietary data format developed by Jeppesen, a subsidiary of The Boeing Company, for use with their electronic pilot logbook software. This format stores comprehensive flight records, including pilot flight hours, aircraft specifications, and currency tracking data. Primarily utilized for data backup and archival purposes, this format is associated with legacy desktop applications that have largely been superseded by modern cloud-based electronic flight bags.
