Robini, I admire your enthusiasm a good deal ---and I know that aviation appeals to you --- may I suggest that you read the Airplane Flying Handbook written by the FAA ass this field takes years of dedicated study and it is important to start with the fundementals first ---but much more precious time may be spent in learning the aeronautical basics as we all start in pipers and cessna's at this stage those books will be more useful to you --- of course continue with your pursuits but let it be tempered by more realistic goals as that is the best path to what seems your ultimate goal ---airplane performance is a very complicated field and sometimes you have to be more humble ---many dedicated professional have sought to assist you but I think that sometimes you get abrasive responses due to you're approach --- I wish pprune was around when I was 15
---but as some have said we must all crawl before we run ---but you sound very intelligent and you should go on to be a very good aviation professional one day----many flight instructors have told me that they hate when folks get to caught up in MSFS because they must spend so much unteaching bad habits ---so, get started learning the basics then worry about the more technical stuff ---just a suggestion
