I applaud your desire to learn, especially since you're venturing far beyond any thirteen-year-old I know, but I remain puzzled on why you confine your questions to the North American forum, since Airbuses (Airbi?) fly all over the world. It also seems to me you're attempting some marathon running prior to learning to crawl. If you're still learning what pitch is, perhaps getting into advanced flight control functions might be a bit premature?
