KDFW Dallas Fort Worth runways and takeoff data

Runways at KDFW

The main direction is a set of five parallel runways (18L/36R, 17C/35C, 17R/35L, 18R/36L and 17L/35R) on 180/000° true. The parallel pair 13R/31L and 13L/31R lies 41° off that axis and is the crosswind option when the wind blows across the main runways.

Lengths run from 2,591 m on 17L/35R to 4,085 m on 18L/36R, a difference of 1,494 m.

Displaced thresholds: 13L 191 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 18L (4,085 m) the A320 example uses CONF 1+F with an assumed temperature of 59 °C, while 17L (2,591 m) needs CONF 3 and 54 °C, so less thrust reduction.

At 607 ft the air is thinner than at sea level, even with the standard-day temperature down to 13.8 °C. On 18L the A320 example takes CONF 1+F and 59 °C; the same 4,085 m runway at sea level would allow CONF 1+F and 61 °C. That gap is the thrust reduction the elevation takes away.

Near its maximum takeoff weight, at 77 t, the A320 example still gets CONF 1+F with an assumed temperature of 50 °C from 18L (4,085 m). The limiting end is 35R (2,591 m), which needs CONF 3 with an assumed temperature of 44 °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.

An illustration for flight simulation, not for real-world operations. Your own numbers depend on weight, weather, runway condition, intersection and obstacles; SkyNexus computes them from your SimBrief plan and the live METAR. See the A320 performance calculator and the 737-800 performance calculator for how it works.

KDFW questions

How long is the longest runway at KDFW?

Runway 18L/36R at Dallas Fort Worth is 4,085 m (13,401 ft) long and 61 m wide, surfaced in concrete.

What is the elevation of Dallas Fort Worth?

Dallas Fort Worth International Airport sits at 607 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 KDFW?

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 KDFW 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 50 °C from 18L (4,085 m). The limiting end is 35R (2,591 m), which needs CONF 3 with an assumed temperature of 44 °C. On a hot day at full weight that is the runway to check before you accept it from ATC.
