Definitions for competitions

In the past there have been some confusion about the different terms and definitions used when describing tasks and scoring of a hang or paragliding competition. FS will try to stay as consistent as possible, to avoid further confusion, and help promote the understanding of how the software and scoring works.

Task
The task pilots must fly. The task is set for each day of the competition, and there are a few variations on how the task is set and flown described below.
Open distance task
Pilot performance is calculated by the distance flown. Task may be defined by only the take off waypoint, or may have open distance on a heading defined by a turnpoint.
Elapsed time task
Pilot performance is calculated by the distance flown and the time used if the pilot completed the task. The elapsed time task consists of a take off, start gate, turnpoints are optional, and a goal. The time is measured from the last time the pilot crosses the start gate.
Race task
Pilot performance is calculated by the distance flown and the time used if the pilot completed the task. The Race task consists of a take off, start gate, turnpoints are optional, and a goal. The task defines one or more start times, and the time is measured from the start time prior to the time the pilot crosses the start gate the last time.
Waypoint
Normally a geographical coordinate, a set of waypoints are used to describe a task.
Turnpoint
A waypoint when used in a task. A waypoint is a point the pilots have to fly within a defined distance of during the task, usually the radius around the turnpoint is 400 meters.
Take off
The waypoint where the task is started from.
Start gate
Normally a circle around a waypoint, where the pilots time start when entering or exiting the start gate. Start gate can also be take off.
Goal
The end of the task. May be a mandatory landing zone. Goals is often ES (See below).
Start of speedsection (SS)
Where the measurement of time starts. ES is the start gate.
End of speedsection (ES)
Where the measurement of time ends. Often the goal, but sometimes before goal for safety reasons. ES can be a physical goal with a visible goal line that corresponds with the coordinates. ES can also be a "virtual" ES with a circle or line from the goal coordinates, where the pilots have to rely on the GPS to tell when goal is reached.
