why does it only have one new engine?

I believe it's testing that engine for the next generation of 747's. They test it in flight and on the ground. The other 3 "old" ones are still fully functional!!

Looks like your sitting at A-9 at BFI. How did you get out on the taxiway? Or, were you at Clay Lacy . . .

It's good to see that a variant of the GEnx engine is going to be entering service on a newer model 747-8i. It really is a beautiful engine that can create greater thrust with better fuel efficiency. Too bad it isn't powerful enough to carry the 747 on just two. Close though. Max output I've seen on the GEnx is over 80,000 lbs thrust.

The conversation between the pilots and the tower was something to the effect of:

T "are you taxiing around on just the on engine?"

P "Yep"

T "can you fly with just the one engine?"

P " oh yeah!"

Pretty sure the takeoff would need at least a couple.

i know the genx engine is better and all but the PW engines looks better and is only beautiful on the 747.

@SuperMpierson That's only for a twin-engine aircraft. There's no requirement for a FOUR-engine aircraft to be able to fly on a single engine!

[SuperMpierson]

@wa22030 Actually, in order to certify a new engine you have to be able to fly it on only the one engine. These babies are WAY over-engineered as a result.

747 8 engines are so much bigger???

[03Wale]

@odyma43 It;s actually a 747-100 series aircraft

[moronist200]

friggin huge!

[10Kingboy10]

they said that 1 of those new engines is powerfull enough to fly one boeing 747-400

they even tested it!

[ImportKilla89]

@wa22030 its the engine used on the new 757 but they r testing its strength

[odyma43]

@enygma3d Technically a 747-200, like this one, could fly on two of those GE engines. The highest output of a GE engine is 115,000 pounds of thrust. Double that and you've got 230,000 pounds. The other three engines put down around 50,000 pounds each. So theoretically, two of those GE engines could easily power this 747. Don't know about the -300 and -400 series though.

What I find terribly ironic is that the 3 baseline engines on this GE- owned aircraft are Pratt and Whitney (JT9D's?)! I understand the aircraft is a -100 and the GE engines weren't mounted until the -200 series, but I simply want to point out the irony.
