The reason that I was talking about engine out thrust to weight ratios is that runway requirements are calculated with an engine out, so it should be a determining factor. , Ceteris paribus plane with the higher engine out thrust to weight ratio should be able to get out with less runway or more fuel. But forget that, please look in the pilot manuals I'm very curious to know how they compare.

Its hard to get data on these planes on the internet. I've always been very interested in why Dassault would make (and why people would buy) their trijets. I don't know if its because of the trijets or some other characteristic of Dassault planes, but I read a lot of praise about the Falcon 50 and Falcon 900 runway performance compared to the GIIIs and GIVs of their time. Yeah the GV has a much better wing than the GIV, but the improvement from the 900 to the 7X should be huge, too. Its also a brand new wing while the wing on the 900 was straight off of the much smaller 50.
