Runways
PIT's airfield features a wide, open layout and four runways, including three east-west parallel runways and a fourth crosswind runway. This configuration allows for the efficient flow of air traffic in nearly any wind condition. The airport's two longest runways are 11,500 feet (3,510 m) and 10,500 feet (3,200 m) in length, allowing PIT to accommodate even the largest of commercial aircraft. However, due to the development of non-aviation related business on airport land, PIT can add only one additional runway (this number was as high as four in the past).
With the availability of three parallel runways, simultaneous landings or departures can be performed in nearly any situation. Runways 10R and 10L are equipped with Category III ILS (Instrument Landing System). Runway 28R is certified for Category II ILS (with special certification, otherwise Category I). Runways 28L and 32 have Category I ILS and Runways 10C/28C has LOC/GS.
The 1991 master plan done during the construction of the new midfield terminal complex for the hub operations of U.S. Airways called for the eventual addition of four runways giving the airport a total of eight. Along with a parallel second "crosswind" runway of 9,000 feet at the southwest corner of the complex, three additional parallel east-west runways of 8,200 and 8,500 feet were to be built on the southern end of the complex with an 8,200 foot runway on the northwest section. Runway 10 C was also planned to be extended to 10,039 feet and the C and D concourses were to be extended for an additional 10 gates each.
