F3K and F3J refer to numbered sections within the competition rules[1] set by the Federation Aeronautique Internationale (FAI). FAI is the Geneva-based organization that tracks most "official" flight records for all kinds of aircraft. F3K is the hand-launched glider class and F3J is the thermal duration soaring class.
