5 Busy Airports Where Intersecting Runways Complicate Takeoffs & Landings

Perhaps the most ideal layout for an airport is the 'pinwheel' arrangement at Denver International Airport (DEN). This allows multiple sets of parallel runways in different directions to operate largely independently. This increases capacity, reduces taxi times, and there are no intersections. However, the problem is that the pinwheel arrangement takes up a significant amount of space, and many airfields simply lack the land to design such a layout. Still, adding runways is primarily how airfields boost capacity.
