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.
