4 CROSS COUNTRY TASKS
• While the aircraft is in the AAT sector and the distance from the previous target to the
aircraft is greater than the distance from the previous target to the current target, the target
is moved further along the projected line from the previous target to the aircraft, just beyond
the aircraft. Hence, the black track line will not be visible but the blue optimal track arrow will
point along this projected direction.
4.7 OnLine Contest
Analysis contains a page ‘OnLine Contest’ which can be used to show the optimal path and
estimated score. The rules for OLC optimizing can be set on the page ‘Rules’, field ‘Online Contest’
of the Task Editor :
• Sprint Conforms to FAI IGC League rules. Up to 5 points including 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 common 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 including 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 Task Editor by turning the ‘OLC Support’
field to ON.
When flying OLC, either AAT or non-AAT tasks may still be used to manage the flight navigation.
During flight, if the ‘Optimise’ button in the OLC page of the analysis dialog is pressed, the computer
will optimise the current flight with respect to the selected OLC rules.
