What is used as a measure of distance covered by aircraft?

Posted by Keshav Jain on



One of the challenges of international flying is handling different units of measure in different countries. In aviation, the battle between imperial and metric units continues. Feet, meters, statute miles, nautical miles, inches of mercury, millibars, hectopascal, knots, meters/second – it can get a little confusing! Read on and I’ll scramble your brain with international aviation units!



World-wide, the nautical mile (nm) is the standard for measuring the distance an aircraft travels across the ground. 



Other lateral measurements are a mess. Most of the world measures runway length in meters while North America uses feet. Most of the world measures airport visibility in meters. North America? Not nautical miles, not meters, but statute miles! Huh?? Not to worry, North America changes back to feet when measuring Runway Visual Range (runway visibility measured with a laser), while the rest of the world sticks with meters. Confused? I sure am, and I do this for a living!
