Why Some Airports Have Intersecting Runways - Military TV

The question is why some airports still have intersecting runways operations? The following scene shows the evolution of Chicago O’Hare runway layout from time to time. This airport changed from a system of three pairs in three directions before 2000, followed by an additional parallel runway in 2008 and some additional improvement in 2015, into a system with six parallel runways and only two intersecting runways in 2021. Between the first and second world war, aircraft grew larger and flew faster. These aircraft required longer runways. Few fields would be large enough to allow landing in any direction. This was exacerbated through the need for a hardened surface, at which point the real “runway” was born. To ensure that aircraft could largely operate against the wind. With heavier aircraft, higher speeds, and longer runways most airports expanded into parallel operations after WWII. Cross-wind tolerance was increasing as aircraft speed, mass, navigation, and control improved. While operation into the wind was preferable, an airport with only parallel runways was no longer an impossibility. All content on Military TV is presented for educational purposes.
