4.11 OnLine Contest

The analysis dialog contains a page ‘OnLine Contest’ which can

be used to show the optimal path and estimated score. The conﬁg-

uration settings (task rules page) allows the selection of which set

of rules to be used for the OLC optimisation:

Sprint : Conforms to FAI IGC League rules. Up to 5 points in-

cluding start and ﬁnish, maximum duration 2.5 hours, ﬁnish

height must not be below start height.

Triangle : Conforms to FAI OLC triangle rules. Four points with com-

mon start and ﬁnish. For tasks longer than 500km, no leg

less than 25% or larger than 45%; otherwise no leg less than

28% of total. Finish height must not be lower than start

height less 1000 meters.

Classic : Conforms to OLC classic rules. Up to seven points includ-

ing start and ﬁnish, ﬁnish height must not be lower than start

height less 1000 meters. Points awarded 80% on second last

leg and 60% on last leg.

The Sprint rules require the start altitude to be the lowest altitude

in the ﬂight after release from tow. The detection of this start point

can be enabled in the task editor, selecting the start point and turn

‘OLC’ to ON.
