new TASKs and SCORING - or roll the dice
"Snead1" wrote in message
I am currently flying with a Cambridge GPS NAV and a L-Nav. I would like to upgrade or add equipment to help me fly the Turn Area Task. What works well and what are the important features that can aid in making correct deci- sions while flying the Turn Area Task?

Mike Borgelt Borgelt Instruments. __________________________________________________ ______ Good point Mike, and probably no one who helped to create the scoring system, described in the FAI SC S3 / ANNEX A ever has thought through the consequences with the eyes of a competition pilot. Officially we have now - RT Racing Task (classic task, fix distance for all) - AST Speed Task - Assigned Areas (var. distance, minimum time) - PST Speed Task - Pilot Selected (var. distance, minimum time) - TAT Distance Task - Assigned Areas (var. distance, maximum time) - TPT Distance Task - Pilot Selected Well - even if you are told what kind of tasks the competition will contain, you will not really know what you get, because 3 different possibilities of scoring are applicable. A. 1000-Points Scoring System: The Score is expressed in points (the maximum available daily Score is 1000 points). B. Kilometre Scoring System: The Score is expressed in kilometres (the max available daily Score is equal to the best Distance of the Day) C. Place Scoring System: The Score is expressed in places (the maximum available Place Score for the Day is 25). D. Or you might have local scoring rules and formulas. Most competitions use the 1000point system - lets have a look. RT Racing Task is the classic task with 2/3 of the max points for speed and 1/3 for distance, if enough competitors return home. I still like it, especially the Australian version with different start points. They give speed points only and if you messed up a day completely you better land short of the home field, even if you could make it home, because you will get more points) AST Speed Task over Assigned Area turn points PST Speed Task over Pilot selected turn points - for both tasks distance is variable a minimum time applies - The winner points are split up 2/3 for speed and 1/3 for distance. - Finishers get the same distance points as the pilot with the biggest distance even if there distance is smaller! - Finishers returning home too early get the speed calculated with the minimum time given. In my opinion this kind of scoring is just nonsense! If more points are given for speed than distance, every pilot will fly the shortest distance to minimise the risk. After the experience of the SA pre-worlds the IGC created the minimum time - what a stupid idea!! For variable distance speed tasks the points should be given equally for distance and speed (50/50%). That would give the pilots a reason to fly as far and fast as possible. Each pilots gets points for his own flown distance and his speed. If done so, the minimum time, which gives the pilot headache to optimise the task, is not needed anymore. TAT Distance Task over Assigned Areas turn points TPT Distance Task over Pilot Selected turn points - for both tasks a maximum time applies - distance points are given only - no penalty is given, if you return home too late, but only the distance taken, flown until the max. time has been reached. I can live with TAT. TPT is fine as long as the weather is more or less homogeneous in the competition area. The only problem is, that normally the task manager will give you a task like that, if weather conditions are very unpredictable. As a result you might in Switzerland have turn points in the mountains, in the flat region or towards the Jura, regions with very different weather pattern. Then it is like throwing the dice - where shall you go? If selecting the wrong region - you are fu....ed. Personally I do not like PST and TPT tasks. Unpredictable weather pattern can just make it a lucky game. I prefer tasks where pilots have to fly in a given sequence to certain areas, and every pilot faces about the same problems. But with the current formulas for AST and PST tasks, I will not fly any competitions using them. It is just a crazy scoring way to compare pilots abilities. I do not need this kind of experience. Then I prefer to spend some nice days flying for fun and declare it in the OLC. Chris Hostettler Melbourne |
