No leading points for a pilots landing between ESS and goal line?

[Joerg Ewald]

The second task of the Swiss League Open was set with a 1km "End of Speed Section" and a goal line. Because of some tough conditions, we had: A: pilots who finished just before the "End of Speed Section" (ranked 4, 6, 9) B: pilots who managed to get inside the 1km "End of Speed Section" cylinder, but had to land before the goal line (ranked 2, 7, 8) C: pilots who crossed the goal line. (ranked 1, 3, 5)

The task was scored using the GAP2007a formula with the same settings as the PWCA (GAP2002, but with Arrival Time Points instead of Arrival Position Points).

What strikes us as odd is the fact that of all the pilots in the above three groups, only the three pilots in group B received 0 leading points - even though some of them flew in front of the field for most of the task. I think this is a bug, which, until resolved, prevents us from publishing the results from last weekend's Swiss League Open.

Joerg,

I am looking at it now. Would be easier if you could zip up the fsdb and the tracklogs for the task and send it to me (st-ter@…).

fsdb and tracks for the task in question

[Stein Tore Erdal]

Looks like you've set distance manually for these 3 pilots. No tracklog in the tracklog column

Seems the reason for this is that you've found another bug in FS.

When I try to check tracklogs for these three pilots I get the distance "NaN" (meaning not a number). I also get lc = 0 which is a side effect.

I think the bug comes in the situation where one has ES circle with a goal-line at center of it instead of a goal circle and one has pilots landing inside the ES circle but not crossing the goal-line.

Changing the goal-line to a circle with 300m radius I get

distance = 58.658 and lc = 1.94863362689391 for Urs

distance = 58.731 and lc = 2.68429425081757 for Mirko

distance = 58.135 and lc = 2.32090046481415 for Jöel

So if you set these values manually then you should get (fairly) correct results.

I will see if I can fix the bug tonight in which case I'll send you the fix.

Fantastic! :-)

FsTaskFlight? 1.2.12.5 with fix for bug described above.

fxd in update of FS 1.2.12 2009-05-08

[Stein Tore Erdal]

Testet in FS 1.2.13. OK.

Very interesting approach to goal in task 2. The top 2 from oppsite sides into the ES circle and then crossing goal-line from the side.

Those doing ES but not reaching goal-line, trying head on...

We like our tasks to be tactically challenging. :-)

Thanks for the fix!
