Your airframe, whatever it is B or AB and the respective variant, is calculated by the load people. Be it Being with BCOP or the Airbus program,it calculates all of the parameters for TO, be it all engine, or EO.
This is all sorted out with the loading of the aircraft, and the temperatures at both DEP and ARR.
As for the questions on DBX, you take off over the Ocean or the Desert. In addition, the worlds tallest building is not an obstacle in the fligthpath.
OP., quite frequently , you will have a temperature inversion at DBX (this, in addition to the associated windhshear, are the reasons why there are so many GA)
The inversion level is very typical, especially the headwind/tailwind, (or vice versa) depending on the time of day. unfortunately, you will have no idea of this with the AWOS at 10M and a balloon reading twice a day.
Knowledge is power, why are there so many GA on final, and on second attempt, success......
