Well i think it will be good if there is a available option to show units in AE using metrics (meters, kilometers and so on) instead of only imperial units available (feet, miles, etc)...

It is basically a license-produced DC-3 but have different production line, different engines and perhaps also a slightly different performance.

The performance below are from Wikipedia, however it is referenced to a encyclopedia book which seems legit.
