There are two types of IGC recording devices available, their use depending on the type of flight performance to be claimed:

IGC-Approved Flight Recorder (FR)

A device for recording the position and altitude of the glider using GNSS satellite data and barometric pressure for which an IDC-approval document has been issued by the GNSS FR Approval Committee (GFAC). There are three levels of approval listed in para 1.4.1 of Annex B to the Sporting Code for Gliding (SC3B):

  1. For all flights (badges, diplomas and records).
  2. For all badge and diploma Flights.
  3. For badge flights up to diamonds only.

Position Recorder for Silver and Gold Badge Flights (PR)

A GPS recorder unit (not as secure as a IGC-approved flight recorder) which may be used for evidence for silver and gold flights only, under rules given in the Appendix to Chapter 4 of the Sporting Code for Gliding (SC3) and amplified in Annix C to this Code (SC3C).

The following pages give more details of these devices, with links to rules and approval documents.
