Does Advanced Aircraft Analysis (AAA) support SI units?
Yes, AAA supports SI units. When you install AAA for the first time it will ask what your default units are and you can set it to SI. You can always change this inside AAA by going to Setup > Units. You can also temporarily change a unit in the calculator. For instance if you have the engine power in hp, but you have setup your AAA for SI units (it will show power in Watt or KW) then inside the calculator you can click the SI/British button and you can enter the power in HP.
