Much has been said that the 2 types have the same runway length requirements. I was just shown a comparison, (by colleges) one from the Airbus web site (AC_A380_05.pdf) and one from the Boeing website (7474sec3.pdf) which shows the A380 needs more runway at higher takeoff weights than the 747. As anyone done a comparison or study? Or have we just took Airbus's word that the A380 uses the same runway length? Also is this why most are loading the A380 light (only 550 passengers vs more)? Your thoughts and help please. I would like to return with the correct information.
Notes: At sea level my colleges say they are close +/- 2000 Ft but at altitude the 747 out performs the A380. I am digging into the information and am asking for help.
