XCSoar User Manual
Waypoints are optionally labelled according to one of several ab-
breviation schemes.
XCSoar continually calculates which landing points are within
gliding range using the current wind estimate. The estimated ar-
rival altitude above the arrival safety height of reachable landable
points is optionally displayed next to the waypoint. This arrival
altitude is calculated at the MacCready setting of zero.
3.6 Active task
The active task course is drawn on the map as a green dashed line.
Assigned area tasks also show the task sectors or areas as a shaded
region. The start and finish waypoint additionally show black cir-
cles and grey lines representing the start and finish zones or lines.
Circles are always drawn around start and finish points, lines are
only drawn if the start/finish points are of line type. Task observa-
tion sectors are drawn as segments.
At all times a thick black line is drawn from the glider to the next
waypoint in the task.
