When visual/manual scoring is used, the landings have to be documented on video.

(No specific requirement is set up for the video equipment, however, it is recommended that the recording is taken with a shutter setting between 1/200 and 1/1000. Reviewing should be possible in “still-picture”/single frame viewing and slow motion mode. A digital video camera is preferable).


The FAI General Aviation Commission (GAC) has implemented 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 Rally Flying, Precision Flying and ANR Competitions

The Requirements are documented in Annex 4 to Section 2 of the Sporting Code. The document can be found here.

A software to convert logger files from GPX format to GAC format can be found here

Application for approval of GNSS equipment must be made to Mr Frank Eckard, GNSS Technical Advisor.
