There are now 63 main types of IGC-approved Flight Recorders from 20 different manufacturers. When different models within types are added, the total rises to 72.

If you own, or fly with, one of these recorders, it is recommended that you download its latest IGC-approval document from one of the web sites given below, and note any changes that may affect how you operate it.

A table of all IGC-approved FRs with links to Approval Documents is the first item on the web site before the set of Approval documents for each type of recorder. This includes the following:

(1) a table of all types of IGC-approved Flight Recorders in alphabetical order of manufacturer name, with links to their IGC-approval documents in the right hand column under "Date of Latest Document".

(2) a table of Manufacturers of IGC-approved Flight Recorders, in alphabetical order of name.

IGC-approval - GENERAL

IGC-approval follows test and evaluation by the IGC GNSS Flight Recorder Approval Committee (GFAC) in accordance with Annex B to the Sporting Code for gliding and the Technical Specification for IGC-approved GNSS Flight Recorders.

The Technical Specification is available through the igc-documents web site above

or

directly from the GFAC web site:
http://www.ukiws.demon.co.uk/GFAC/do..._spec_gnss.pdf

Programs that have been notified to IGC for the analysis of IGC files are listed on the GFAC web site under: "Analysis Programs for IGC Flight DataFiles"

Validation than an IGC file has the correct structure and that the file is the same as initially downloaded from the FR, is achieved either through the IGC Shell program, or through analysis programs such as SeeYou that include IGC Shell within their overall program and provide a file Validation facility in their menu.
IGC Shell may be downloaded he
www.ukiws.demon.co.uk/GFAC/downloads.htm
This downloads the file IGCDLL.zip, which when un-zipped, gives the free IGC Shell program. This web site also contains the latest FR Manufacturers’ Data Link Library (DLL) files that are used by IGC Shell and other programs to Validate the structure of an IGC file. The IGC file Validate check ensures that the IGC file came from a serviceable and secure FR, and the file is identical to when it was originally downloaded. This check is required before a flight performance recorded in the IGC file can be approved to the standards of IGC.

Finally, the Sporting Code for gliding (SC3) and its annexes A-D may be downloaded via: www.fai.org/igc-documents in which "Sporting Code - Section 3: Gliding" is at the top of the list
