Update: WeGlide responded to my questions with this:
... thanks for reaching out. We use data from the OGN Device Database.
1. Update the name in the OGN Device Database <-- Suggesting that I could designate a specific 'ASH 31 Mi xxm' wingspan in the OGN Device Database
2. Remove them in the OGN Device Database <-- WeGlide's glider dropdown list keeps offering aircraft I don't own nor have registered in the OGN Device Database
3. The coach is independent of the live tracking configuration and uses the aircraft that is selected for that flight <-- this answer is direct and makes sense
While we do read the aircraft type from the igcfile, if you update it once for a flight, we'll always suggest the correct aircraft in the future. <-- not sure what this means?
On question 1, I searched the OGN DB and the entry for my glider does not provide any wingspan config info:
In fact, OGN's device entry process provides a dropdown list and there is only a single entry for 'ASH 31 Mi'. There is no wingspan config to choose. So, I sent a question to OGN support asking if they added '21m' to that entry in the dataset they send to WeGlide just to confirm WeGlide's assertion. OGN's primary role is aircraft tracking so I don't think the wingspan configuration is relevant to their mission - but maybe they insert some additional model designation characters in the data they provide to WeGlide. (While looking through the OGN DB, I came across a wingspan designation only for a 'DG 600 18m' but not for a DG 800, LS8 or any of the other gliders that I was looking at).
I also sent this in my reply to WeGlide: Considering a pilot can fly in different configurations, isn't the wingspan config something we should be able to choose within WeGlide when performing a task setup?
Question 2 regarded old registrations that WeGlide keeps offering in the dropdown list. I no longer own those registrations and they don't appear my OGN devices list (nor do I have access to them in the OGN DB). But apparently WeGlide did decide to correct this since they were remove from the dropdowns when I tried it again this morning.
Since I'm paying to use WeGlide (and OLC's continued existence is questionable), I'd like the basic capabilities to work properly.
