Thanks. Sound like it is using external wind unless you select one of the other options (circling or zigzag). It was indeed a bit confusing so glad this got simplified. I assume there is also still the option to enter wind manually as well.

Reading that (again), the best interpretation I have is that if you choose Manual for wind calculation, then you get External Wind if it's available.

But if so, how do you override External with Manual if you want to do that?

I don't know.

You could always try LK8000, wind works fine in that, though now I use
external from the SN10. Before that though, the LK wind and SN10 wind were
always very similar Again however you have to configure it correctly, but
it is only one setting.

Last time I looked LK8000 does not run on Android.

If Manual means external than those who use external wind can no longer set it manually. This is a problem since occasionally you want to manually enter expected wind instead of current wind to get realistic final glide calculation when you know the wind at lower altitude is different. I don't understand why not simply add "external" option.

My understanding is that even when there was an explicit external option, if it was selected, and there was external wind present, then the manual wind was overridden by it at all times.

So, pre 6.8, with external wind you do not have manual wind.

Seems all they did with this change is to make the UI more consistent with the implemented logic.

To do this the right way, would require a Settings choice between External source and Internal calculation, and a use choice in the Wind modal that lets the user override the Settings choice with a Manual wind, with the ability to clear it and go back to the Settings choice once the user is done with the need to use the Manual values.

David

with pre 6.8 I simply unselected the "use external wind" whenever I wanted the set the wind manually. It worked well. I am hoping there is a way to achieve the same in 6.8 - having the ability to easily switch between external to manual wind. Without this I am better off with 6.7.

OK, more speculation about how this works. Looking at the code.

In =6.8, if wind is set to Manual (not Auto), and External wind is present then External is used. If you then set wind manually, that overrides the External wind.

In the Modal, once you select wind manually, a "Clear" button appears (it is not there before). Select 'Clear' once you are done with the Manual wind and it goes back to using External (if present).

Hope that's how it is.
