If I said a certain European aircraft consortiums STC manufacturer aircraft weighing reports. Would that be enough for you without me facing libel charges ?
although they call it "calcul du centrage avion en %mac"
When I came across it I could not fathom it as it just sits there, no explanation! and thought perhaps I'm missing something hence the large amount of web searching before finally posting here.
As I can use the arm and weight from the report I shall continue as before using my own methods.
