AVIOFILE is a digital logbook for general aviation and microlight pilots, aircraft owners, co-ownership groups, flying clubs and flight schools. Log a flight once, in four steps: the same entry goes into your pilot logbook and into the aircraft's technical log, and updates the hour meters and maintenance deadlines. It includes a pilot logbook with totals, 90-day recency and EASA-format PDF export; import of an existing logbook from Excel, CSV, Word or PDF with a preview and no duplicates; aircraft tech log, maintenance programme and deadlines by date and by hours; co-ownership with shares, invitations, bookings and shared costs; and tools for flying clubs and flight schools: members, fleet, flight credit, training records and ground classes. Free for pilots. Available for iPhone and iPad, Android and as a web app, in 32 languages, with data stored in the European Union.
