I found a month ago an Excel file (chart) on this forum. But I can't find it anymore. I don't remember if it was a post attachement or an external link.
It was a grid, comparing Wing area and airplane weight. By looking at this chart you can see if you had something, light, normal, on the heavy side or not flyable.

Someone know where I can find this file?
Looks like the file I attach to this post, but in Excel.

Thanks.
