EIDW Dublin runways and takeoff performance

Runways at EIDW

The main direction is a set of two parallel runways (10L/28R and 10R/28L) on 097/277° true. 16/34 lies 60° off that axis and is the crosswind option when the wind blows across the main runways.

Lengths run from 2,072 m on 16/34 to 3,110 m on 10L/28R, a difference of 1,038 m.

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 10L (3,110 m) the A320 example uses CONF 1+F with an assumed temperature of 59 °C, while 16 (2,072 m) needs CONF 3 and 50 °C, so less thrust reduction.

At 242 ft above sea level the air is as dense as it gets, and the elevation costs nothing: the A320 example on 10L matches the same runway at sea level (CONF 1+F, 59 °C).

Near its maximum takeoff weight, at 77 t, the A320 example still gets CONF 2 with an assumed temperature of 49 °C from 10L (3,110 m). The limiting end is 34 (2,072 m), which needs full takeoff thrust (TOGA) with CONF 3, no thrust reduction at all. 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.

Where the 737-800 assumed temperature is marked max it sits on the FCOM maximum; elsewhere the runway or the climb gradient sets it. Where flaps 5 does not fit, the example takes the optimum flap instead.

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.

EIDW questions

How long is the longest runway at EIDW?

Runway 10L/28R at Dublin is 3,110 m (10,203 ft) long and 45 m wide, surfaced in concrete.

What is the elevation of Dublin?

Dublin Airport sits at 242 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 EIDW?

In our reference example (70 t, ISA, calm wind, dry runway, full length) the A320 uses CONF 1+F 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 EIDW limits a heavy A320 takeoff?

Near its maximum takeoff weight, at 77 t, the A320 example still gets CONF 2 with an assumed temperature of 49 °C from 10L (3,110 m). The limiting end is 34 (2,072 m), which needs full takeoff thrust (TOGA) with CONF 3, no thrust reduction at all. On a hot day at full weight that is the runway to check before you accept it from ATC.
