The FAI General Aviation Commission (GAC) is implementing the use of GNSS Flight Recorders to simplify methods of gathering and certifying flight data, and to use more objective methods for measuring flight performance data.
Currently approved GNSS loggers are compulsory in Air Rally and Precision Flying Competitions.
Annex 4 (2007 edition) to Section 2 of the FAI Sporting Code defines the Requirements for Equipment used for Flight Validation. The document is effective 01 January 2007 and is available for downloading here.

GAC uses basically the IGC Requirements documented in ANNEX B TO SPORTING CODE Section 3: " TECHNICAL REQUIREMENTS FOR EQUIPMENT USED IN VALIDATION OF FLIGHTS " ( last edition ). The necessary deviations required for motor flying have been included in Annex 4 to Section 2.
Equipment for gathering flight data, approved by the International Gliding Commission (IGC) in accordance with ANNEX B TO SPORTING CODE Section 3 will be accepted by GAC if the specific requirement for motor flying are met and a formal approval is granted by GAC.
Equipment not yet approved has to go through testing by GAC experts before it can be used in GAC events.
