The situation was that I dropped all ballast early in the race, I remembered that there was something with the flapring and the ballast, but hadn't thought about it before. So I used the flapring like it is. I know now that without ballast the flaps have to be set at lower speed to more negative
FYI: CoTASA takes into account the actual ballast content to determine the optimum flap speeds (it uses the same reference as the flaprings)

Thanks Bre901 for that. I think, CoTASA is a good tool and recommands nearly all to use. But not for me. My way is a little bit different. A very important part of the game for me is to understand. If I use a ready good working tool (like CoTASA), I will get the results and the hints what to do, but I will not understand, why. My way is of course longer and surely less successful, but I need this way for me.

So I like to make my own tools and of course my own mistakes. What have I learned today?

I got 0,25 m/s more sink with wrong flaps. If I see on the statistic, I had 14 lifts with 387 m = 5.418 m. Average climbrate is 1,71 m/s, so 3.168 sec. climbing. The flight was 2:30:50 = 9050 sec. 5.882 sec. not climbing, loosing there 0,25 m/s = 1470 m. Climbing 1470 m with 1,71 m/s = 860 sec = 14 minutes. That's not the whole difference to the winner, only 30 %, but it would be easy, to make it better next time. With CoTASA I wouldn't have made this mistake, but, as I said, I need this mistake to learn more, to see the whole picture. And I don't need first of all the success in rankings, because I do it only for fun. My success is the understanding. Climbing up in the rankings will come one day or not, we will see.

My tool got an extension today, it shows now the correct calculated flapring, not very nice, only as a table, but it does exactly, what I want. And I have full control over it. It's in quality far behind your tools, it has no connection to Condor, I use it on a separate laptop by hand. But it works and helps me.

To share it would be possible, but it's not necessary, because your tools are better. And I'm working with Notes, so it needs a Notes-Client to run. I don't expect that someone here has a Notes-Client running.

But if someone wish, I can share the ideas of the tool, maybe there are some useful things in it

- stopwatch from race-start
- countdown from race-start for AAT-tasks
- table with the speed and kilometers to reach in the rest of the AAT-time
- stopwatch for climbrate, showing a table with the climbrate by meters height difference
- remaining waterballast in liters and percent
- corrected flapring depending on the remaining waterballast

All shown on one screen

- and last but not least, calculating the length of 10 km in centimeters for the printed task, to mark the course (can't calculate it fast and correctly in the few minutes before join in by hand) ;-)

Last word from me to day 5. Flap -2 was wrong too, over 174 km/h without ballast it should have been S. A test with S and S1 shows, that S gives a positive Vmet, S1 is too much and gives a negative one.

Could you post a screenshot of your tool at work, please? :) Would be easier to imagine...
As for CoTASA - I use it in very minimalistic manner - netto only and flaps pos.
No matter where you go... There you are...

Of course, here. I try to explain, what you see

aat.png
COLUMN 1 (Flaps)

+2 (Flap position)
94 (speed on ring) 90 (speed with current weight) -4 (difference, here 4 less than on flapring)

COLUMN 2

1:43:34 (countdown for AAT, with a start and reset key)

186 (max water) 140 (current water) / 75 % (current water in %) (start stop key, 1 liter / sec)

0:01:27 (stopwatch from start, same key as countdown)

01:07 (stopwatch for the climbrate, sep. start stop key)

51,15 kg/m² (current wingloading)

COLUMN 3 (distance)

80 138,1 (138,1 km can be flown with 80 km/h until countdown is 0. More interesting at the end of the flight)

COLUMN 4 (climbrate)

54 0,8 (0,8 m/s average climbrate by 54 m height difference in 1:07 -> column 2)



As I said it's running on a separate laptop, no connection to Condor. So the tool doesn't know anything about what happens on Condor. If I drop water, I have to do it on Condor and in the tool a.s.o.. Works so far I don't forget it ... ;-). For the climbrate I have to remember the height difference.


I can create configuration documents like this and start the tool with it. Flapring data I took from CoTASA, thanks a lot Bre901

Funny: Countdown and stopwatch in the screenshot have a difference of 1 sec, maybe that was the snipping tool on the running screen :-D.

Hello all!

We're after very last day of WCC.... Congrats to Frank, Helmut (flying HC), Stephen and Jon. Well done!

Results of D6 at cc:
https://www.condor.club/comp/showtask/208/?id=18585

Overall after six days => final results on cc.
https://www.condor.club/comp/globalscore/211/?&id=586


As always - some data to study...

SCI stats: FTRs > CoFliCo > IGCs > SCI 2.63b Click to enlarge
WCC_D6.jpg
mCR: average climb rate in m/s for the task | mGN: mean gliding number (gliding number without influence of wind) | mIAS: mean indicated airspeed
(the speed you see on your speedometer, the real speed is higher depending on the altitude) | nLift: number of lifts | DeltaGN: additional gliding number
(difference between mGN and GN of speed polar) | Vmet: average of rising and sinking air | AltLift: average climbed in a lift | Detour: Detour in percent,
only gliding passages are regarded.
If someone would like to have all ftrs to refly with ghosts or igcs for deeper analyse etc. Drop me a msg.



Top three flights of Thu. Again - 1000 m barrier almost all the time, worth to remember. :)
