I respect this and I also like your style. There are good and bad texture artists both when it comes to PBR and texturing using photographs. It all comes down to how well you know your craft. I think you have mastered the art of texturing using photos. The only thing I don't like about this method and especially in a game engine as advanced as Microsoft flight simulator are glass textures with baked reflections. It just gives a very early 00's look and goes against graphical achievements made. I think high polish surfaces should be represented using proper PBR that allows the game engine to render reflections without interference of baked in reflections from when the photograph was taken. Other then that I see no issue.
