Yeah i figured it would. It is really foggy here today plus all the wildfire smoke. Visibility at the plant is maybe like 40 feet

Probably won't improve dramatically until Thursday night at the earliest. Wouldn't be surprised if it got pushed back until Friday.

Still foggy in Everett but not as bad. I have a feeling it will be delayed again

Yup, first flight for N779XZ (WH004) delayed again. This time to Saturday, September 19.

June/July are about the only time of year when it's not foggy around Seattle/Puget Sound mid-day, I thought. I've long wondered why Boeing doesn't move more of their testing elsewhere (be it Moses lake or something like VCV). Yes, first flight still has to happen where they build it, of course....

It is a "fog" created by significant low-level smoke generated from the large forest fires to the north, east and south. Local air quality is terrible (worse than most any other city on the planet) and covers most of the state so atmospheric conditions at Moses Lake are likely as bad as Seattle and Everett right now.

They do use Moses Lake a lot, but the flight test crews, mechanics, and engineers live in and are based out of the Puget Sound area. Also I don't think most flights have very tight ground level visibility requirements, but first flights of each test airframe are a time for extra precautions.

As the 4th test aircraft is online. I believe the GE9X is coming close to the end of its own certification right? As I think ETOPs is I think the last major step. Someone with better knowledge please correct me

WH002 is being ferried to Yuma International airport today for operational connectivity testing

https://twitter.com/mattcawby/status/13 ... 02497?s=21

Someone with better knowledge care to elaborate on what it entails.

Secondly seeing at its being “ferried” is it staying there for a period of time?

Flight plan has been filed, BFI-NYL 1:15PM - 3:36PM as BOE2. I think 'ferried' just means that they'll fly there for testing without doing testing en route, not necessarily that they will stay in Yuma for a while, but I could be wrong. Not sure what the exact test (Operational Connectivity Testing) means.

A different question; given that LN 1669 (a 777-F) is already flying, does that mean that every 77X until LN 1668, the 18th 77X (!!), has already rolled out as well, probably without engines and in primer? Or are they not built in exact LN order for now because of the delay in first delivery?
nobody has ever died from hard work, but why take the risk?

I don’t think they’re built in LN order at the moment

I believe the current production focus is on 777 Freighters as customers are ready and able to take delivery so those frames are being prioritized in the FAL.

Yep there is one 777x in the main line 777 building right now which is 1652 Emirates

The 777x has its own LRIP building and the next plane to come out of there will be 1656 which is a Qatar bird

They already have one black mark against them for delaying the whole program due to their "durability issue" that was serious enough to prevent flight test for many months. If they miss on SFC it'd be an even worse black mark against them.

Looks like some kind of ETOPs. Lightsaber said we will begin to see more tests like this as the GE9X has been certified and now focuses on ETOPS and getting in more hours

Oh, ok. Thanks :)
Makes sense that they would start ETOPS testing now with the GE9X certified, strange that they didn't leave Yuma earlier to get back before night fall though. :confused:

Also, with XW based out of GEG and XX in YUM, hopefully we'll start to see them visit VCV and other testing spots/see them branch out the 779 testing program further.

According to lightsaber in the thread of the GE9X certification topic the rumours are that the engine met its targets.

According to what I'm hearing. I called it rumors. I do not have a hundred flights of data to compare with low and high predictions.

What I do not know is durability. I'll flat out say having only 1,000 hours of flight testing count towards the estimated 3,000 hours needed for ETOPs means there were so many changes made to achieve stable operation (fluttering compressor stators=bad) and fuel burn, there was a lot of potential lessons learned that weren't.

The engines are not as proven as the GE-90-115 was as this stage of flight testing. Not even close.

But indications are the performance team is as smug as such a team can be during the "prove it" stage of flight testing. The fact 1,000 hours of testing is acceptable towards ETOPs means "no more fiddling engineers, I mean it!" So the design is frozen. Truly frozen as someone who knows the pain of certification while optimizing performance late in the game can understand.

At this point, no more software updates until ETOPs, on the engine. Zero. Rev x.y.z must have not one bit changed on the GE9x FADAC (the FAA will do bit checks, I'm serious). There will still be airframe "patches."

Probably not a good place to hang around with a camera, too much military activity. I know of a spotter who got rumbled there and had all kinds of law enforcement to deal with

I found the answer earlier on. The weights keep the plane from tipping. Mods feel free to delete the post.

I’d guess if there needs to be a volume of flight hours for ETOPS rating at EIS then may as well kill two birds with one stone.

GE to perform GE9X sand-ingestion tests in 2021.

I'm officially confused. Every engine certification I participated in, the sand, ice, water, small bird, and large bird ingestion testing was part of the engine certification. So I assume that testing is complete, I can only interpret this as a durability testing program.

Yet the GE9x is certified:

The newer engines run hotter, have tighter tolerances and cooling channels. This creates more spots where either sand blocks a cooling air passage or (even worse) melts and then solidifies in a hot section of the engine.

As this is such a critical test for Emirates and Qatar. This is a late for such testing by 2 years...

They have done all that testing, so i was a bit confused by what this testing is about.

UPDATE: i read the article, its durability testing

There is a 777-9 that is supposed to take off from Everett today and land back at Everett under BOE280. I don’t know whether that is an error but I’m pretty sure there are only engineless 777-9s at Everett

That testing is happening late in the program, but with the delays, GE can deal with most consequences

I'm certain GE can deal with the consequences. I'm equally certain such testing ,with the engine meeting some minimum criteria, would be a condition of accepting delivery by Emirates and Qatar. I hope Boeing spelled out the penalties for being late of AAB gets to set the delivery terms (free cancellations?).

That's probably Qantas 787-9 VH-ZNL, doesn't look like it will be flying today.
