A Participation Title (TP) or a FFSA practicing license is mandatory for all drivers & 2nd drivers participating in the driver pack.
The TP is individual, so each pilot must subscribe to a TP.
Participation passes allow any unlicensed individual to participate in certain FFSA activities. Participation passes are issued in specific disciplines.
Receipt of the participation certificate by its holder constitutes a commitment to comply with the rules of the FFSA and the safety rules, as well as the disciplinary authority of the FFSA.
