Imperial system

There are systems of measurement other than metric that are inarguably relevant to aviation and aerospace, regardless of anyone's nationality or preference. Real-life flight instruments measure by knots and, oftentimes, feet.

Don't be that guy who smashed up the Mars Climate Orbiter because of messing up with imperial units. Metric is international, let it stay such and get accustomed :)

I would like this if included were Nautical Miles and Knots for distance/airspeed

but as an option only
