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!
