    3 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.
    4 
    5  Task::
    6   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.
    7 
    8  Open distance task::
    9   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.
    10 
    11  Elapsed time task::
    12   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.
    13 
    14  Race task::
    15   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.

    164
    175 Waypoint::
    18   Normally a geographical coordinate, a set of waypoints are used to describe a task.
     6  A point having an ID, geographical coordinates, and optionally an altitude and a name.
    197
    208 Turnpoint::
    21   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.
     9  A '''circle'''. It is defined by a waypoint with a given radius. In the case of the last turnpoint in a task, it may be a line instead of a circle. In FS 2 x "radius" is used as the length of the line. All turnpoints in FS has an open and close time.
     10 
     11 Task::
     12  One or more turnpoints make a task.[[BR]]
     13  ''Note: take off and goal/landing is also called turnpoints.''
    2214
    2315 Take off::
    24   The waypoint where the task is started from.
     16  Normally the first turnpoint in a task.
     17
     18 Start of Speedsection (SS)::
     19  The turnpoint where the measurement of time starts.
    2520
    2621 Start gate::
    27   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.
     22  A time defined on the Start of Speedsection (SS) turnpoint.[[BR]]
     23  ''A race task has at least one start gate which is normally the same as the open time of the turnpoint. It may have more start gates in which case it is a race with multiple start gates. A pilot is given as start-time the nearest start gate prior the actual time the pilot took the turnpoint.''
     24
     25 End of Speedsection (ES)::
     26  The turnpoint where the measurement of time ends.[[BR]]
     27  ''Sometimes goal, but sometimes a turnpoint before goal for safety reasons.''
    2828
    2929 Goal::
    30   The end of the task. May be a mandatory landing zone. Goals is often ES (See below).
     30  Normally the last turnpoint in a task (unless it is an open distance task).[[BR]]
     31  ''Can be either a circle or a line. Goal is normally also the landing field.''
    3132
    32  Start of speedsection (SS)::
    33   Where the measurement of time starts. ES is the start gate.
     33 "Race" task::
     34  A task with '''two''' or more turnpoints where one turnpoint is the start of speedsection (SS) and has one or more start gates, and another (later) turnpoint is the end of speedsection (ES).[[BR]]
     35  The pilot's start-time is the nearest start gate prior the actual time the pilot took the SS turnpoint.
    3436
    35  End of speedsection (ES)::
    36   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.
     37 "Elapsed time" task::
     38  A task with '''two''' or more turnpoints where one turnpoint is the start of speedsection (SS), and another (later) turnpoint is the end of speedsection (ES).[[BR]]
     39  There are no start gates and the pilot's start-time is the actual time the pilot took the SS turnpoint.
    3740
     41 "Open distance" task::
     42  A task with '''one''' or more turnpoints. A pilot's performance is the distance flown via all turnpoints then straight in any direction from the last turnpoint.[[BR]]
     43  ''A "true" open distance obviously has only one turnpoint which is the take off.''
     44
     45 "Open distance on a heading" task::
     46  A task with '''one''' or more turnpoints + a heading from last turnpoint.[[BR]]
     47  ''In FS this heading is defined by adding a "heading" point to the task. The "heading" point is '''not''' a turnpoint and is not intended to be flown to, only to be used to find the heading one should fly from the last turnpoint in the task. So, If you fly off the straight line from the last turnpoint to the heading point do '''not''' turn towards it, keep flying in the '''original''' heading showing on your GPS just after you took the last turnpoint.''
