// -- Output Settings -------------------------------------

// You can choose to enable Metric or Imperial or both.
// If you enable both, by setting PreferMetric to either true or false,
// you control which unit is displayed first.

// The Metric setting controls whether metric (m, km, km/h) or

// and in the detailed plane info. If ShowOtherUnits is true,
// then the other unit will also be shown in the detailed plane
// info.
