I can't connect GPU after landing and parking with engines on. I pressed button many times in the FMS and pop-up FMS. Parking brakes are on. So i'm starting APU+gen then turning plane engines off, and only then i can connect it. Am i completely wrong with the procedure or it's an error? Thanks for the airplane btw, it is amazing!! And a question about forthcoming patch. Where can I download it once it's released, this site or x-aviation, patch or full install, will you or x-aviation give a notice upon the release?
