Luftrettungsstation Würselen, as the ADAC Luftrettung designates it, was the first to receive a "Christoph Europa" name for its helicopter, underlining the service's cross-border operability. D-HXAD is at least the third machine with the shown name and wears additional titles of the regional emergency services, StädteRegion Aachen Rettungsdienst, on the door. It sits on its home base trailer here, with engines running.
