OMDB Dubai runways and takeoff performance

Runways at OMDB

The main direction is a set of two parallel runways (12R/30L and 12L/30R) on 121/301° true, so every runway points the same way and a strong crosswind affects all of them alike.

Lengths run from 4,351 m on 12L/30R to 4,447 m on 12R/30L, a difference of 96 m.

Displaced thresholds: 12R 715 m, 30L 132 m, 12L 450 m, 30R 300 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.

At these conditions the A320 takes off with CONF 1+F and an assumed temperature of 61 °C from each runway end in the table, V2 160 kt.

At 62 ft above sea level the air is as dense as it gets, and the elevation costs nothing: the A320 example on 12R 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 12R (4,447 m). The limiting end is 30R (4,351 m), which needs CONF 1+F with an assumed temperature of 52 °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.

OMDB questions

How long is the longest runway at OMDB?

Runway 12R/30L at Dubai is 4,447 m (14,590 ft) long and 60 m wide, surfaced in asphalt.

What is the elevation of Dubai?

Dubai International Airport sits at 62 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 OMDB?

In our reference example (70 t, ISA, calm wind, dry runway, full length) the A320 uses CONF 1+F 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 OMDB 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 12R (4,447 m). The limiting end is 30R (4,351 m), which needs CONF 1+F with an assumed temperature of 52 °C. On a hot day at full weight that is the runway to check before you accept it from ATC.
