Polar boxes not working
Hi - I know there have been previous posts on this but I am struggling with our polar boxes not populating. They just have a -- in the box. The performance polars are loaded. I have also tried other boat polars to no avail. They also don't populate in Ventus. The navigation polars are working, we can optimize a route and that works.
Per a 2019 post here, I deleted the Expedition registry keys, and reloaded the polars but that did not make any difference.
Other ideas? It worked at one time, then we moved to a new computer and it stopped then.

Re: Polar boxes not working
Do you mean Polar bsp %?
Mke sure you have bsp, twa and tws. You also need polars loaded.

Re: Polar boxes not working
Just for grins, make sure the polar is still loaded in the Perf tab of the polars..Recently I thought I had Perf polar loaded but when I checked it was empty. Don't know if it was an upgrage in there or what??

Re: Polar boxes not working
The issue was that I was not receiving TWS & TWA from the instruments (and I thought I was). Once I marked the calculate TWS/TWA setting, the polars worked.
Thank you Nick!
