The IGC format
Most of us know the IGC file (en: International Gliding Commission) as a file that a vario creates, in which the flight path is recorded and which can be uploaded to one of the Internet portals, such as the DHV-XC or XContest, after the flight. When opening the file with a normal text editor, you can recognise some information in plain text, but most of the data is very cryptic. However, it is worth taking a closer look at what is hidden behind it in order to better understand the background to airspace violations, for example.
