Currently I am at a competition. Task finish is defined as a 5km circle.
I always arrived higher than supposed. Therefore I tried a simple task in simulator mode. What I see is, that the task finish calulation refers to the middle of the finish circle. In my opinion it should refer to the finish of the task, that is the circle line at 5km, because the arrivle hight is defined at this cirle (here 170m airfield elevation + 300m = 470MSL).
Is there a way to adopt the setup?
Thank you for help!

I think you're asking for too much, getting an answer is optional on this forum

It's been 2 months today since I asked a question on the LKMAPS Desktop thread

Hi Bruno, thank you for this information. Yes, I think you made a version for me. That is probably the reason why I remember this issue as solved. But because there are newer versions - that I of course downloaded - the problem came back unexpetedly. I tried to find out the rules for required task hight in the LK8000-documentation. But I faild due to the chained list of (many) documents. What about the idea to reference always the finish line of a task undependently of its shape. I never had a finish specification that did not consider the airport arrival possibilities.

Just my 2 cents,

did you establish the finish height by setting the safety height to 470m MSL? If so, yes then the center of the circle is used in the calculations

I think it will work as intended when you set in the task rules (config 2/3 System Setup page 14, click button 'task rules') the 'Finish Min. Height' to 300m (finish minimum height is defined in AGL, see HELP) and 'safety height' to 0 (config 2/3 System Setup page 6).
I have used this during a competition a few weeks ago and I had the impression it worked fine this way (LK8000 stable version)

I did not set safety height to something. It is always set to zero. In task rules I set the finish min height to 300m. If you fly a task in simulator mode with this settings, you will see that the difference-height of the task refers to the center. At the finish circle you will arrive higher. This is what happens in a real finish too. These statements refer to version 7.2.1
Best, Kai
