XCSoar User Manual
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 com-
puter will optimise the current flight with respect to the selected
OLC rules.
In the OLC analysis page, the aircraft track is shown as a thin
green line, and after optimisation, the optimal path is shown as a
thick red dashed line.
If continued flight in final glide will result in higher score, the
displayed results are shown as ‘In progress’ and a blue line shows
the projected path to improve the score. For Sprint and Classic
OLC types, this path is extended in the direction to the current
waypoint. For Triangle OLC type, this path is extended in the
direction to produce the largest triangle.
The score and computed optimal distance is approximate.
If continued flight in final glide will not achieve a higher score,
or if the aircraft has landed, the displayed results are shown as
‘Finished’.
Depending on the duration of the flight, the time required to cal-
culate the optimum path may take up to 10 seconds.
