KJFK New York JFK runways and takeoff data
John F. Kennedy International Airport (KJFK/JFK) serves New York, United States, at 13 ft above sea level. It has 4 paved runways; the longest, 13R/31L, is 4,423 m (14,511 ft). Below are the runway dimensions, how the layout works, and an example takeoff for the A320 and the 737-800 from each runway end of at least 1,800 m, worked out with the same performance engine SkyNexus uses for your own flights.

The main direction is a set of two parallel runways (13R/31L and 13L/31R) on 121/301° true. The parallel pair 04L/22R and 04R/22L lies 90° off that axis and is the crosswind option when the wind blows across the main runways.
Lengths run from 2,560 m on 04R/22L to 4,423 m on 13R/31L, a difference of 1,863 m.
Displaced thresholds: 13R 623 m, 31L 995 m, 04L 141 m, 22R 822 m, 13L 276 m, 31R 314 m. A displaced threshold shortens the landing distance from that end, not the takeoff run.
Example takeoff performance
Flap setting, assumed temperature (FLEX) and V1/VR/V2 in knots for an A320ceo at 70 t and a 737-800 at 72 t, from the start of each runway of at least 1,800 m. Conditions are a standard day so runway length and airport elevation are what change: ISA temperature at the runway elevation, QNH 1013, calm wind, dry, no obstacles.
Runway length shows in the numbers: from 13R (4,423 m) the A320 example uses CONF 1+F with an assumed temperature of 61 °C, while 04R (2,560 m) needs CONF 3 and 56 °C, so less thrust reduction.
At 13 ft above sea level the air is as dense as it gets, and the elevation costs nothing: the A320 example on 13R matches the same runway at sea level (CONF 1+F, 61 °C).
Near its maximum takeoff weight, at 77 t, the A320 example still gets CONF 1+F with an assumed temperature of 53 °C from 13R (4,423 m). The limiting end is 22L (2,560 m), which needs CONF 3 with an assumed temperature of 46 °C. On a hot day at full weight that is the runway to check before you accept it from ATC.

The A320 V2 values include improved climb: with a long runway and a high assumed temperature, V2 is raised above its minimum so the one-engine climb gradient still holds. That is why V2 runs higher on the longer runways.
The 737-800 assumed temperature is at its FCOM maximum (marked max) from each runway end in the table, so at 72 t the runway is not what limits it.

Your own numbers depend on weight, weather, runway condition, intersection and obstacles; SkyNexus computes them from your SimBrief plan and the live METAR.

KJFK questions
- How long is the longest runway at KJFK?
- Runway 13R/31L at New York JFK is 4,423 m (14,511 ft) long and 61 m wide, surfaced in asphalt.
- What is the elevation of New York JFK?
- John F. Kennedy International Airport sits at 13 ft above sea level. Elevation lowers air density, which raises true airspeed at a given V-speed and lengthens the takeoff run, so it matters for performance.
- Which flap setting does an A320 use for takeoff at KJFK?
- In our reference example (70 t, ISA, calm wind, dry runway, full length) the A320 uses CONF 1+F or CONF 2 or CONF 3 here. On a real day the answer moves with weight, temperature, wind and the runway condition; SkyNexus works it out from your SimBrief flight plan and the live METAR.
- Which runway at KJFK limits a heavy A320 takeoff?
- Near its maximum takeoff weight, at 77 t, the A320 example still gets CONF 1+F with an assumed temperature of 53 °C from 13R (4,423 m). The limiting end is 22L (2,560 m), which needs CONF 3 with an assumed temperature of 46 °C. On a hot day at full weight that is the runway to check before you accept it from ATC.
