What is a .igc file?
File Extension Details
The IGC file format is a standardized data format used primarily in the aviation industry, specifically for gliding, paragliding, and hang gliding. It was developed by the International Gliding Commission (IGC) to provide a secure and uniform method for recording flight data from GNSS (Global Navigation Satellite System) flight recorders. These files contain a chronological log of a flight, including GPS coordinates (latitude and longitude), pressure altitude, GNSS altitude, and timestamps. One of the most critical features of the IGC format is its security mechanism; it often includes a digital signature, known as a G-record, to ensure that the flight data has not been tampered with after the flight. This security is essential for validating world records, badges, and competition results within the soaring community. Beyond simple tracking, IGC files can store metadata about the pilot, the aircraft, and specific task declarations. They are widely used by flight analysis software to reconstruct flight paths in 3D, analyze thermalling performance, and verify that pilots have successfully rounded specific waypoints during a cross-country task. The format remains the global standard for flight verification in non-powered or foot-launched aviation.
