The runway system at John F. Kennedy International Airport (JFK) consists of two pairs of parallel runways: 4L-22R, 4R-22L, 13L-31R and 13R-31L aligned at right angles. Total runway length is nearly nine miles. All runways have high-intensity runway center lights and taxiway leadoff lights, and the surfaces are grooved to enhance safety. An Engineered Materials Arresting System (EMAS) is installed at the departure end of Runway 4R for aircraft overruns.
Runway 4R-22L is 8,400 feet long by 200 feet wide and is equipped at both ends with Instrument Landing Systems (ILS), Approach Lighting Systems (ALSF II) with sequenced flashers and touchdown zone (TDZ) lighting. Runway 4R is a Category IIIB ILS runway, permitting landings with a visibility down to 600 feet or more by qualified aircrews and aircraft. Runway 22L ILS allows landings down to a visibility of less than a half-mile. Runway 22L is equipped with a Precision Approach Path Indicator (PAPI). Takeoffs can be made with visibility of one-eighth of a mile.
Runway 4L-22R is 11,351 feet long by 150 wide and is also equipped with ILS at both ends down to three-quarters of a mile visibility. Takeoffs can be conducted with one-eighth of a mile visibility.
Runway 13L-31R is 10,000 feet long by 150 feet wide and is equipped at both ends of the runway with ILS and ALS systems. Runway 13L has two additional visual aids for landing aircraft, a Visual Approach Slope Indicator System (VASI) and a lead-in lighting system (LDIN). The ILS on 13L has Category II capability and, along with TDZ lighting, allows landings down to half-a-mile visibility. Takeoffs can be made with visibility of one-eighth of a mile.
Runway 13R-31L is 14,572 feet long by 150 feet wide and is one of the longest commercial runways in North America. Visual landing aids on 13R, including VASI and LDIN light systems, allow visibility conditions down to three-quarters of mile. Takeoffs on R/W 13R and 31L can be made with visibility of one eighth of a mile.
Taxiways total over 25 miles in length. Standard width is 75 feet, with 25-foot heavy-duty shoulders and 25-foot erosion control pavement on each side. The taxiways have centerline lights and are generally of asphalt concrete composition 15 to 18 inches thick. An illuminated sign system provides directional information for taxiing aircraft.
