Hello,
I know that you can change the unit preference for SD but I would suggest to also add unit preference for the aircraft details (eg W&B).
Renting Cessna & Robin, I have to switch around when completing the aircraft profiles & W&B. I think it would be easier to crosscheck that everything is correct is you could determine which unit to use per aircraft.

Any comments & views are welocome.
