Rather alarming to read that as nano-meters briefly!
- t0mas88 6y agoHaha, just millimeters from crashing in that case. Aviation is terrible at any kind of SI or even any kind of sane standardization of units at all. Distance is commonly measured in nautical miles (1852 meters), but visibility in the US is in statute miles (1600ish meter?) or feet, while Europe uses km or meters for visibility. Both US and Europe use feet for altitude, but China/Russia use meters for altitude.
- navaati 6y agoI did, too, but I still don't get it. Is it a typo for "min" (as in minutes) ?
- tialaramex 6y agonm is "nautical miles". A "nautical mile" is a unit that feels more natural to people concerned with the globe shape of the Earth than the conventional mile (of 1609.34 metres) because it was equivalent to one minute of latitude. Today it's just defined as 1852 metres.
