Issue with distance calculation on specific task

Reported by: danielvelezbravo@… Owned by: Stein Tore Erdal
Priority: major Milestone: 1.1.5
Component: FsComp Version: 1.1.4
Keywords: Cc:


Hello there. I´m doing the excersise of interpolating all the data from our previous hang gliding nationals into the software to see how it goes. On one specific task, called 12M, with pilot ID 3, Alejandro Isaza, I´m having a big issue with the tracklog as, even when you can see on the map that the pilot made the turnpoint 3 after the startgate, and that he got the time right, he´s getting minimum distances as if he was just a couple of hundred meters off the turnpoint. I messed around with the task configuration to see where the problem was, and found out that if I make the turnpoint 650 instead of the 400 mts original setting, then the tracklog would be ok. He was using an old garmin 12 with few tracklog points so he set the interval to 15 seconds. I´m not sure if the software needs more trackpoints than just one in order to get a turnpoint. I´m attaching the comp database and only the 12M task tracklogs on kml, and also the igc tracklog for Pilot ID 3. Can you tell me if this is an issue or if the tracklog is bad (Compegps said it was ok by then, and I can´t see any issues inside the igc file that could lead to a bad track).

It´s still an issue on 1.1.4.

I can´t set the distance on waypoint 3 (first turnpoint after startgate, that´s inside the start radii) to 400mts that´s the right one. Instead I must force it to be of 650 mts in order to get pilot Alejandro Isaza to get it. Nevertheless, on Compegps and even on FS task and flight map, you can see that the flight shows that the pilot did the 400 mts mark by far on turnpoint 3.

You can use the previously attached file for verification. If you like, I could sent the whole competition.

Ok. I found something really buggy.

When loading the 3.kml flight into FSCOMP and into Google Earth, the track shows that the flight did cross the 3 turnpoint 400 mts radii. Nevertheless, when I open FSFLIGHT and load the competition, and load the 3.kml track, it appears quite different, with less points (on FSCOMP shows points #113 and #114 within the radii) and quite far from the radii, showing point #113 even outside the 2000 mts entry start circle, and the next one, the #114, 1750 mts away from the #113 and more than 100 mts away from the 3 radii. So there´s something wrong on the FSFLIGHT in comparison with google earth and FSCOMP.

It happens that under the options on FSFLIGHT if I uncheck the track log filter, the missing but quite necesary trackpoints get back, so the filter is not working right.

The issue would be that on the FSCOMP, the Track Log Filter under options is not getting reflected on the tracklog displayed on the map, so you wouldn´t really know if the tracklog that you are looking at is the one that´s getting scored as in my case.

A clear bug :-(

Very special case though and hard to detect. When using filter the first 9 points in the tracklog 3km from first tp is removed (regardless of any logic).

In 99,9% of all tracklogs this does not cause any problem, but of course it should not be so.

Will be fixed asap...
