Finally, in the simulation you can get a rough estimation about how loop changes on the main lines of your wing affect the AoI and symmetry of your wing. You can select the various loop options by clicking on them to see how the AoI in this section of your wing or the symmerty might be affected.
Newly selected loops are thereby indicated with a yellow , while the loops that you've indicated prior to your measurement are indicated with a white .
The indicated lengths for each wing and loop that we use, get optimized with each measurement of loop changes that we get. This means that, for wings that have never been used for measuring and trimming by a user, the suggested length changes are only assumptions while, for wings that were used many times, the estimates fit pretty well to reality. Provided that your quality of measurement is good and that the loops that you indicate prior to the measurement were correct.
