Niegowoniczki airstrip (polish Lądowosko Niegowoniczki) is a small airstrip located in southern Poland, about 30 kilometers east of Katowice which was missing from Flight Simulator 2020.
It's a small grass airstrip with a single grass landing strip, 02-20. Strip is 470 meters (1160 feet) long by 30 meters (100 feet) wide, but has extensions at each end making its full size 1120x30 meters (3600 feet long). There are several hangars on the southern end of the airport. In reality there is a polish forestry service airbase here with a single patrol aircraft stationed.
This addon uses only basegame models, so it's not true-to-life, however placement is pretty accurate.
