Yeah, very impressive. I really liked those 12,000'+ take-off rolls on DFW's 13,401' long 17R in August when it is 105 degrees (F). Of course, the A-340-200's longer brother, the A-340-300 used up just as much runway. Gotta love those four hairdriers.
The B-777-200/ER is a better airplane.
You know, a bit of harmless bragging about performances, hairdriers and the likes is ok, but when someone let's all this clouds his judgement to the point of making such senseless remarks there's a problem.
The 772ER has a significant margin in thrust to weight ratio and nobody will dispute that is somewhat bigger than the usual twin vs quad unaivodable margin. Yet in the one engine off scenario the A343 at MTOW beats the 772ER at MTOW by a similar margin... This meant that in most cases the A343 use all this runway lenght just because it _legally_ can, whereas the 772ER (or any similar big twin) cannot.
The A343 does not come up short in short field take off performance even compared to other quads. I humbly suggest that you educate yourself about the fact that -for instance- AF
A343 does SXM
nonstop, while all 747 services from SXM
to Europe where/are forced to a tech stop.
Naturally a 772ER (or a A330 for that matter) is nowhere ever remotly capable of that ...
