DXB Rwy 12R
Trying to save myself from a roundtrip to Dubai 
NOTAM and Jeppesen show that RWY12R is 2650m, crews reporting an runway length marker at the holding point indicating 2600m.
Can anyone tell me which one is right!

are you going to DXB to measure the runway???
It wouldnt be the first time!
In an FMS equipped aircraft with no manual way of adjusting the performance data for shortened runways, its confusing not to mention inconvenient to have crews taxi to the holding point with takeoff data based on 2650m, only to see a sign telling them that the available runway length is 2600m!
While it is more conservative to use 2600m, we need more justification that a single pilots report to justify doing so!

Hi Mutt,
2650 is correct for 12R. That is for performance calculations only.
Nearly the full length is avaliable for landing. The reduced length is only being caused by WIP off the end of the runway. There is a large pile of sand there at present.
The opposite runway 30L has nearly full length available for take off.
Most local operators use 12L (4000m) for take off when heavy and also 12L for landing due to there being no ILS on 12R at the moment. 12L is still CAT 11.

ND you are not quite right, in fact, EK have a company notam recommending 12R use where possible to increase the traffic flow rate.
ARMGAT, 12R at 2650m increases the thrust required to miss the obstacles at the far end but still gives you 4000m of concrete to stop. Most local operators use 12R unless they are either luddites or at MTOW. It is a TODA obstacle (sandhill) limitation rather than a TORA/ASDA problem.

ARMGAT,
Its winter time around here, the temperature isnt close to 45°C, plus our flights are short haul, so 2600m is acceptable.
Thank you for the information gentlemen, but can anyone answer the question about a conflicting runway length sign showing 2600m?
Cheers.

Mutt, I think the answer to you question is which side you enter the runway from. If you enter from the north side (M), you have the full length. If you enter from the south (K7?), you lose 50 m because of construction at the button.
