That was discussed just a few posts ago. There is no ASL data inside logs. And I can't think any use of that data anyway.
I can see great use for that data info. I would also prefer to see it live in flight. I live near a 100ft drop-off to a valley below. So when I launch from Home Point behind my house and ascend up to a 200ft altitude and then fly over and above this valley, of course it remains at 200ft on the on-screen display in the GO app. It needs to be at 300ft.
Now maybe I'm wrong, but I would tend to think that our Flight Logger provides the data needed to put together some type of elevation data?
