F3j Is another variant of thermal duration flying. SSL has begun to run F3J events bi-annually as an alternate to the F3b. Several club members have represented Australia in F3J and have flown to the F3J rules during Open Thermal events. SSL is hosting a bi-annual competition.
This is a 3 discipline contest involving Thermaling, Speed and Distance. It has been described as the Triathlon of the gliding world. It is competed as an individual event where the most technically advanced gliders are launched by high powered winches. Competitors are typically grouped in to team of 4 to spread the load of spotting, timing and retrieving the winch. The three disciplines are:
- Duration: The same as Open Thermal rules with the exception of the limit of 2 launches.
- Distance: To fly as many complete laps of a 150 metre course in 4 minutes.
- Speed: The quickest time to complete 4 laps of the same 150metre course.
SSL hosts a biannual international F3B event with pilots coming from overseas and interstate entering to compete.
