About .igc Files

IGC files are plain text files used to record flight log data in aviation, especially for gliding. They follow the MIME type text/plain and store structured flight information such as timestamps, latitude, longitude, and altitude.

Based on information from FilExt.com, IGC files are critical for verifying flight paths and performance in competitive and recreational aviation.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs

What is an IGC file used for?

An IGC file is a standard flight data format defined by the International Gliding Commission (FAI/IGC). It records GPS track logs, altitude, and timestamps for gliders and paragliders to verify flight performance in competitions and badges.

How do I open an IGC file on my computer?

Because these are plain text files, you can open them with any basic editor like Notepad or TextEdit to view the raw data. To visualize the flight path on a map, you should use specialized software like SeeYou, GpsDump, or online tools like IGC Webview.

Can I convert an IGC file to Google Earth format?

Yes, IGC files are frequently converted to KML or KMZ files for viewing in Google Earth. Several free online converters and desktop tools like GpsDump can transform the flight data into these formats or the generic GPX format.

What is the correct MIME type for IGC files?

IGC files are fundamentally text-based, so they are often served with the MIME type text/plain. However, in specialized aviation applications, you might see them associated with application/vnd.fai.igc to trigger specific flight analysis software.

Can I edit an IGC file manually?

You can edit the file in a text editor, but doing so will invalidate the G-Record (security signature) at the end of the file. If the digital signature is broken or doesn't match the file contents, the flight log will be rejected for official competition or record claims.

Why does the IGC file look like a jumble of letters and numbers?

The file follows a strict structure where every line starts with a specific letter code (e.g., 'B' for position fix, 'H' for header). This compact format allows the file to remain small and easily parseable by software, even though it is technically human-readable text/plain.

General FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
