Performance

I would like to question whether those who generalize and compare Dubai ( thus EK) and Abu Dhabi ( thus 9W or EY) have flown in that region or just compare the two because of the close geographical proximity? I would like to highlight to those who keep comparing the two( if interested) that Dubai has a runway which is 1100 Ft longer than Abu Dhabi, that the elevation difference of close to 60 Ft makes a difference, that Stop-ways have an effect on performance, that runway slope has an effect so please stop comparing the two.Each degree celsius rise drops the RTOW by close to 3 tons above 42 degrees C in Abu Dhabi. The EK and EY aircraft both operate with a T/O bump thrust setting and 9W aircraft do not have that at the time being so until that gets sorted out 9W aircraft cannot accomplish the mission that EK can
