4 engines vs 2 for ultra longhaul
Ladies, Gentlemen,
Can someone please help me understand how Singapore's A340-500 is able to fly from WSSS to KEWR nonstop but the 777-2LR can not fly that long of a leg? I'm probably missing alot of other factors here and excuse me if I am but if the triple can fly this leg of over 9,000nm why isn't it used? Thank you all in advance for your thoughts.
Cheers,
Slim
