Microsoft flight sim data
Rather than being sarcastic why don't you contribute something more intelligable Lima Oscar? Aircraft data for the add is accurate enpugh as they use AFM.Microsoft Sim Dlt Planning Data is npt exactly rubbish as you would like us to believe.I fly real planes but have used MS for play as well as analysis for over a decade.I won't trash it like you did.If you are unable to make a contribution I advise you stay away and or I will report you.
