Sector turn-points are 90 degree segments aligned to the bisec-
tion of the previous and next waypoints, as commonly used in FAI
tasks. There is also support for German DAe sectors.
Automatic advancement of the start task depends on the type of
start:
Cylinder : When the glider leaves the cylinder area.
Line : When the glider crosses the start line.
FAI 90 sector : When the glider crosses the start sector lines.
Automatic advancement of intermediate waypoints depends on their
type:
FAI Sector : When the glider has entered the observation zone, defined
by a segment and radial distance from the waypoint. The
segment is defined by a 90 degree arc centered about the
bisector of inbound and outbound legs, with a distance of 20
km.
DAe 0.5/10 sector : When the glider has entered the observation zone, defined
by a segment and radial distance from the waypoint. The
segment is defined by a 90 degree arc centered about the
bisector of inbound and outbound legs, with a distance of 10
km. The observation zone also includes a cylinder of 500 m.
Cylinder : When the glider has entered the observation zone defined by
a radial distance from the waypoint.
AAT : When the glider has entered the observation zone defined
by the radial distance from the waypoint, and segment for
sector areas.
Task completion depends on the finish type:
Cylinder : When the glider enters the cylinder area.
Line : When the glider crosses the finish line.
Competition rules may be defined in a profile file for distribution
to a group of pilots or task-setters, so all competitors are playing
by the same rules!
Additional task rules for valid starts and finishes may also be spec-
ified. Starts may have a defined maximum altitude above ground,
and a maximum speed. Finishes may have a minimum altitude
above ground. These parameters are defined in the page “Task
Rules” in the configuration settings. If any of the values are zero,
the corresponding limit rule is not applied.
