Some good news out of the Pacific Northwest! Boeing wrapped up two days of factory gauntlet testing on the 747-8F yesterday and they're running through some final functional tests before RC501 can officially leave the factory for the paint hangar. She's going to look sharp in the company colors.

Onward,

She may still beat the 787 to first flight. Question is whether that is the politically correct route

It's hard to believe that there is another, improved version coming down the line of a lane I first flew in '76.

Even if it is a Freighter I'm delighted to see the 747 continue.

And finally with engines large enough to make it look aggressive. The Queen's been working out and now she's ripped...  Wink

Um, what does political correctness have to do with it?

So it appears the leading edge and engine pylon re-design and re-fabrication work they needed to do looks to be not all that extensive (not that anyone claimed it was, but it did require the engines to be removed which pushed back all the testing).

I think that if an e-mail ever came to light telling the 747 crew to delay first flight so the 787 could take off first you'd see stockholders with torches and pitchforks at the gates.

Great News! If they were both ready to fly at around the same time my vote is a one day launch for both!

So between now and first flight stands paint job, intermediate and final gauntlet testing, low and high speed testing. That this will take at least 2 months, with first flight expected not to happen before the end of the year, seems like a conservative time-line to me - certainly for a derivative. OK, the 787 completed factory gauntlet testing April 21, with first flight at that time expected to happen 2 months later. But that seemed not illogical for a completely new model with all kinds of unknowns. So, can we expect first flight of the 747-8 in the first or second week of January?

Pardon my lack of knowledge on the topic, but is there a difference in the diameter of the 744 and 748 engines. I always understood that increasing engine size would require a significant rework of the landing gear to increase height or was that included in the 748 design?

The GEnx-2B67 has a fan diameter of a bit over 104" compared to the 93" of the CF6-80C2-B1F.

Good news undoubtedly. I can't wait to see the first pic outside the factory. She's an absolute beauty with the larger engines and classic 747 lines.


oh boy!!!

Grand old ladies should go first. Young whippersnappers should stay back in their place.  Big grin

What would they do for 2 months? Adding up the testing you list is something like 4 weeks.

Sure! She can show the newcomer how it's done!

You're thinking of the 737 I think, which has pretty low clearance between the engines and ground.

Nah, I remember reading a post on here that mentioned a limit on the engine size of the the 747's inner two engines.

That's what I'm wondering about... Why is Boeing so conservative with their estimated first flight date not being before the end of the year?  Confused And in the meanwhile reiterating that the 787 will fly this year, with apparently more work to do with less time to spare.

A few more special conditions for 747-8 certification were released/proposed by the FAA in August and October. Could that be a factor?

Yes the pylons have been redesigned to allow for the greater size of the new engines.
