What is an IGC file?
The .IGC file extension is primarily used for flight data logs. These logs are created by GPS flight recorders in gliders. The FAI International Gliding Commission defines this file format. These files store flight paths, altitudes, time stamps, and GPS coordinates. Pilots use .IGC files to analyze flights and verify competition results. A secondary use for the .IGC extension is the Anime List Builder Input File, which is developed by IGC.
How to open IGC files?
You can open gliding .IGC files with specialized software. Examples include SeeYou by Naviter, tools by Flarm, or OGN-FLIGHTBOOK. Because these flight log files contain plain text data, you can also view their raw contents using basic text editors like Notepad or TextEdit. If your file is an Anime List Builder Input File, you need the specific Anime List Builder software.
