Scoring 2019 - overview

2019-12-16 17:05
The purpose of this blog is to give a brief overview of the scoring process.

For the last few years in South Africa, due to mounting costs of scoring, Livetrack24 has been used as our scoring platform. In the ideal world, each pilot would have a tracker and spectators/friends could monitor progress and scoring would be autonomous. This is currently not possible for various reasons, so a two step process is followed:

Step 1: All Tracklogs captured in LiveTrack24 which is also used for registrations. Two of the many phone Apps that can be used are FlySkyHy for Apple ( )  or TTliveTrack24 for Android ( The pilots upload their logs each day if their tracking device does not work.

Step 2: The scoring team take the tracklogs and do an initial scoring run in FS Score (The official scoring software of the FAI The tracklogs are downloaded from LiveTrack and the scoring is performed and reported on. Note that sometimes a track shows goal in Livetrack24 but not in FS Score. This can be due to Ellipsoid tolerances and the fact that FS score is slightly more accurate than LiveTrack24. In this case, it is best to submit your tracklog from a dedicated flight instrument (not a phone).

As can be seen, this can be an iterative process as pilots may need to submit revised logs and the scoring then gets run multiple times until everybody is happy (or their scores are accurate at least!).

General comments
- It helps scorers when you submit your tracklog to Livetrack24 as soon as possible after landing
- Please let scorers know if you don't fly as each pilot must be accounted for - i.e. absent / turkey etc
- Don't panic if your provisional score doesn't match Livetrack - just contact the scoring team with your IGC file from a flying instrument

2.4.        ALL pilots need to complete a competition indemnity before permission to access the Take Off area can be granted.

3.           REST DAYS
There will be no official rest days.

Pilots are invited to first settle any disputes with fellow pilots before lodging a complaint.
Should the dispute not be settled, a complaint may be made to the Meet Director or his deputy, by any pilot, in writing, to request a correction. It should be made with the minimum delay and it will be dealt with expeditiously.
If the complainant is not satisfied with the outcome the pilot may make a protest in writing to the Meet Director or his deputy.
The time limit for protests is 4 hours after the publication of the provisional task results or the results of the complaint, except that after the last contest task it is 1 hour. The protest fee is R500. It will be returned if the protest is upheld.

5.           TAKE-OFF METHODS

5.1.        Foot Launch from hill site. Take-off site is Leeuwenkop and back up site is Dasklip. Details can be found on the Map.

There are only 2 frequencies that can be used during the competition.  The first is the Flying and Safety frequency of 141.600MHz and the second will be the Retrieve and Coordinating frequency of 141.625MHz.  There will be no “team frequencies” and pilots are not allowed to receive information or assistance via any communication.  Radio frequencies are meant to be kept open for communication.  Only frequencies allocated by the organisers may be used.  

7.           RETAKE-OFF
A competitor will be allowed a second re-launch to attempt the task within the stated take-off period. A failed take-off attempt or safety problem arising immediately after take-off which results in a landing will not count as one of the permitted number of take-off attempts.  However, the pilot's take-off time will be taken from the time of the first take-off attempt if a ground start is specified.  A re-launch pilot will not take priority over other pilots who have not yet launched at all.  All pilots wishing to use the retake-off must land in the official “Turkey patch”.  The official transport will leave “turkey” 45 minutes before the close of the window.

8.           TASK PERIOD.
Times of the window open for take-off and times for the closing of the window, turn points and last landing will be displayed on the Taskboard on take-off. Any window extension policy will also be displayed on the Taskboard. The minimum period of time that the launch window will remain open for the day to be considered valid is 1 minute per pilot.  Launch Window Extension Time will be announced at the task briefing and may only be used when the launch has been closed for safety reasons.

9.           WIND SPEED
The maximum wind speed in which a task shall be at the discretion of the Meet director and the advice of the Safety committee.

10.1.      FS Software by FAI will be used with GAP latest scoring formula.  Leadout Points and Drop task will be used as well as Arrival Time points.

10.2.      It is the Pilot's responsibility to ensure that their tracklogs are submitted to  Instruments/Trackers/Smartphones should be configured to transmit to

10.3.      In the event that there was an error in the transmission of the tracklog, it is the Pilot’s responsibility to download his/her tracklog in IGC format (with a valid G-Record) from their own flight instrument and upload it to the relevant task on

10.4.      Pilots should ensure that they keep a copy of their tracklog in IGC format with a valid G-Record should the organisers request a copy for validation.  Preferably this should be kept on your flight instrument but a downloaded copy would be acceptable as long as it contains a valid G-Record.

10.5.      Team per country Scoring – Teams per country must be announced before the first task and consist of 5 pilots maximum, with the 2nd and 3rd pilot scoring per day for the team. More than one team per country can be entered.

10.6.      For the scoring purpose, guest pilots are counted as competing pilots.

10.7.      Scoring a stopped task.  When a task is stopped, the pilot’s scores will be determined from their GPS track log position 5 minutes before the time that the task was stopped.  The Altitude of the pilot at this time will also be used in the calculations of the final points.

10.8.      The map datum used will be WGS84 and the format for coordinates will be 
ddd mm.mmm'

10.9.      Scoring will be done according to the FS Software scoring programme, the version  using the GAP 2015 scoring formula. GAP parameters will be discussed and decided at the Pilot Briefing.  The following parameters are a guideline and must be voited in at the first briefing before task 1.

Info about Flying here

Info about flying here:
Porterville is located in the South West of South Africa, about 90 km from the Atlantic ocean, and 120 km North East of Cape Town. It offers a good mixture of thermal and dynamic flying, offering big-distance flights on the ridge and in the flats. 

The town itself is situated in the vast Swartland valley stretching West, South and North. On the East it is bordered by the Winterhoek Mountain range, that serve as a natural barrier from Atlantic winds passing into the centre of the country, known as the Karoo.

Leeuwenkop is the most commonly used take-off site in and around Porterville. It is the safer of possible take-offs in anything south of west, due to its height, and that it faces more directly into the prevailing thermic cross-wind. 

The latest site record was set by Wim Verhoeve in January 2016 with a straight line disstance of 188km. (Western Cape Record). Record flight on Leonardo

Another great flight by pilot Alfredo Studer in December 2011 with a XC distance of 227km. Xcontest track

Take off Leeuwenkop - S32º55.616’ E19º02.235’, 800m (ASL).
Winds: W - SSW, thermic SE days. 
Take off is a netted area in the fynbos. Top landing is possible.
Landing: Field in front of take-off.
- It can be more cross and stronger than it seems on take-off.
- In summer, experienced guidance is highly recommended.
- It is not a beginner site.
- Drive North out of town.
- Turn right onto the dirt road sign posted "Dasklip Pass" after about 5km.
- Drive up the pass and around the back.
- After 5km take the track to the right.
- Park in the clearing and walk to take off.
