FAI Sporting License
A valid FAI sporting license for the year is nominally required to participate in any FAI category 2 competition. If you want your results to count for WPRS (World Pilot Ranking System) points, then a sporting license is required. To acquire a License, mail the application form to the Aero Club of Canada. The form can be found here: ACC Sporting License Form.
