A bit of an insight of the situation is achievable via Google Earth.
Enter "Föhren" into the search tab >> next amplify a bit and focus on the RWY 22 marking. Very well visuable is a displaced threshold. Apparently even the obstacle surface sloped 1 : 40 for VFR flights and runways is not clear of obstacles, therefore the displacement.
Than moving east beyond the village of "Hetzerath" near extended center line there is a foto linked into Google Earth named "Flugplatz Trier - Föhren; langer Endanflug".
I assume those of the community that have to deal with similar airfields more frequent immediately know that this is not a "honey".
Definately and for all recognizable a VFR / VMC field only.
