Distribution of Airports by Altitude

Distribution of Airports by Altitude

Like the distribution of the world’s population, the majority of commercial airports are located at lower altitudes. More than a third of airports are sited at altitudes of less than 100 feet (30 meters), and three-quarters are sited at less than 1,000 feet (300 meters). Aircraft taking off at higher altitudes require a longer runway due to lower air density.
