attempt to clarify SS open time and startgate(s)

Definitions

There is some confusion about the different terms used when describing tasks and scoring of hang or paragliding competitions. 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.

This needs to be synced up with Section 7 terms, OE have started looking into this.

Waypoint
A point having an ID, geographical coordinates, and optionally an altitude and a name.
Turnpoint
A cylinder. 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 cylinder.
In FS 2 x "radius" is used as the length of the line.
All turnpoints in FS has an open and close time.
One or more turnpoints make a task.
Note: "Start" and "Goal" is also called turnpoint.
Start
Always the first turnpoint in a task.
Start is normally a cylinder placed on take off. Note: Start does not mean "Start of Speedsection" (SS), although in some cases it may be the same turnpoint.
Start of Speedsection (SS)
The turnpoint where the measurement of time starts.
Startgate
A time defined on the "Start of Speedsection" (SS) turnpoint.
A race task has at least one startgate which is normally the same as the open time of the turnpoint. It may have more startgates in which case it is a race with multiple startgates. A pilot is given as start-time the nearest startgate prior the actual time the pilot took the turnpoint.
NOTE: If first startgate is after the open time of the SS turnpoint, pilots starting in the periode between the open time and the first startgate will get distance but not time points (unless the scoring formula used decide differently).
End of Speedsection (ES)
The turnpoint where the measurement of time ends.
Sometimes "Goal", sometimes a turnpoint before goal for safety reasons.
Goal
Always the last turnpoint in a task.
Can be either a circle or a line.
Goal is normally also the "Landing". In the case of open distance tasks, obviously the last turnpoint is not goal or landing field.
Takeoff
The area where pilots take off from. Normally this is where the "Start" turnpoint is placed with a radius big enough to cover the area.
Landing
The area where pilots land after flying the task. Normally this is where the "Goal" turnpoint is placed.
