Nautic miles or statue miles?

[1993matias]

Just a little question here:

I have just bought two 180-million dollar planes believing they were able to fly 7600 nautic miles (8400 miles, Bangkok-Denver), but it could only fly 7600 miles (6400 nm, Bangkok-Seattle). Now I can't really use them on high-profit routes, but only to medium airports.

Is there a reason why AM is using nm as unit, when the distance is measured in miles? Is it supposed to say nm, or is it an error?

I mixed up the measurements when I first started AM and the issue has been compounded ever since. We've buried our heads in the sand when it came to tackling the issue though.
