Final approach runway 28 with D-EOIC Piper Archer 28 inbound DonauwŲrth-Genderkingen airport on a cloudy and very windy day. Since 8 weeks Regensburg has no longer high trees around the airport. Now it's much more difficult to approach the airport because of unpredictable wind shears. Note that the runway has a gradient when approaching via runway 28. We were just needing about 400m with the Piper and the landing was no problem. Oberhub is a nice small airfield and very commendable.
