This add-on fixes the wrong runway slope of the default Stuttgart airport EDDS, which was introduced with WU6.

If the fix doesn't seem to work, please check also the priority of your scenery packages with the Package Reorder Tool in the General Options - Experimental menu. "sierrabravo-edds-runwy-fix" must have a higher priority (located below) than "microsoft-airport-edds-stuttgart", otherwise the original Microsoft EDDS is used. If necessary, you can rearrange the order by using the arrow keys next to the priority numbers.
