Pretty sure it's media and employees only.

I am getting more and more excited as the development process approaches significant milestones such as roll-out, but in particular first flight. The excitement of the 787's first flight was something special. The A350 first flight day was also special as was the A380. I cannot wait for the day the Mighty Triple 7 reincarnates itself.

The answer is complicated. March weather in around here is iffy. So unless they are sure the weather is good, the roll out ceremony may be inside the hangar. They may open the hangar door to let looky-loos peek in side. If they open the hangar door, you may be able to hang around the fence line outside while watching the live stream.

I'll get blasted for this, but the fuselage still looks "old" to me. I'm sure Boeing's livery will help a lot, but not standard customer paint.

They even hold the rollouts inside when the weather isn't bad - remember the 748-i? It was inside behind a huge curtain which was lowered to reveal the aircraft.
The 787 was more of a "roll in" - aircraft was outside, everyone was inside and they opened the bay doors and tugged her inside

The length of the 9-variant should be noticeably longer. This should give it a pleasing look. I hope that there are opportunities to fly it over the snowy mountains during the testing stage. I remember how beautiful the 787 looked as it glided over the white-capped mountains all those years ago.

Great to know!! Is Mr Rainier always snow-capped? Either way, some of the testing will occur during winter and all should be good.

Yes, Mt. Rainier has +14000ft elevation and is snow capped year round.
If flight test starts about a month after roll out, in April, you will still have snow on much of the Cascades and Olympic Mt ranges (two places they like to do photo shoots).

From Wiki

With 26 major glaciers[24] and 36 sq mi (93 km2) of permanent snowfields and glaciers,[25] Mount Rainier is the most heavily glaciated peak in the lower 48 states. The summit is topped by two volcanic craters, each more than 1,000 ft (300 m) in diameter, with the larger east crater overlapping the west crater. Geothermal heat from the volcano keeps areas of both crater rims free of snow and ice, and has formed the world's largest volcanic glacier cave network within the ice-filled craters,[26] with nearly 2 mi (3.2 km) of passages.[27] A small crater lake about 130 by 30 ft (39.6 by 9.1 m) in size and 16 ft (5 m) deep, the highest in North America with a surface elevation of 14,203 ft (4,329 m), occupies the lowest portion of the west crater below more than 100 ft (30 m) of ice and is accessible only via the caves.

We're a slightly below normal year, so far, but I've slogged through snow as low as 5000' in June in the heavier years.

Here's a September photo, when snowpack would be near its minimum for the year:

And here's a November photo (plus a really cool story about an unusual holding pattern an Alaska airlines pilot requested when landing was delayed by heavy fog at SeaTac). It would not be unusual to see similar coverage in April:

I notice in the video link there, when he is interviewing the painter (at around 4:30 mark onwards), he says the painting will take on the longer side of the 4-7 day estimate because of "the new livery, something we've never done before". Hmmm....

My understanding was that he just meant that this will be the first application of the new Boeing scheme on a new model and that's something that they haven't done before. As in like: "...never before they've painted a 777-9."
But I'm open for surprises.

I believe both types will have the same engine and thrust ratings.



The family of the Image.GE9X, twin-shaft, high-bypass, turbofan engines (fan diameter: 3.403,6 mm / 134,0 in; BPR: 10,0:1; engine architecture: 1F+3LPC–11HPC2HPT–6LPT), OPR: 61,0:1, aimed for the propulsion of the future Image.Boeing 777-8 / 9 aircraft will be rated in the range of 414 kN / 93 klbf - 467 kN / 105 klbf and will include the following models of the engines:
……
…….GE9X-105B1A
…….GE9X-105B1A1
…….GE9X-105B1A2
…….GE9X-105B1A3
…….GE9X-102B1A
…….GE9X-102B1A1
…….GE9X-102B1A2
…….GE9X-102B1A3
…….GE9X-93B1A

Despite the breathtaking size of the General Electric GE9X, the engine is less powerful than the Image.GE90-115B engine. The revised aerodynamics of the Boeing 777X aircraft and the larger wings means less thrust is required to get the aircraft in the air.

Image

The series of the General Electric.GE 90 engines with the 128" fan: GE90-110B1 rated at 492,69 kN / 50.240 kgf / 110.760 lbf, GE90-113B rated at 505,01 kN / 51.496 kgf / 113.530 lbf and GE90-115B rated at 513,95 kN / 52.408 kgf / 115.540 lbf, exclusive powerplants for the Boeing's latest additions of the 777 family of the aircraft: 777-200LR, 777-300ER and 777-200F, were projected with a lot of power and thrust reserve inside, rated not nearly to their upper limits (during the certification testing at GE's outdoor test facility in Ohio, in 2002, the GE90-115B, two-shaft, high-bypass, turbofan engines (fan diameter: 3.251,2 mm / 128,0 in; BPR: 9,0:1; engine architecture: 1F+4LPC–9HPC2HPT–6LPT), OPR: 42,0:1, rated at 513,95 kN / 52.408 kgf / 115.540 lbf set a world record reaching 568,93 kN / 58.014 kgf /127.900 lbf of thrust. The engine ran for approximately 60 hours at triple red-line conditions: maximum fan speed, maximum core speed and maximum exhaust gas temperature, all that to evaluate the engine at its operational limits. As such, those GE90 engines (128" fan) are not extremely effective and fuel efficient (by the current criteria), but compared to the Image.Trent 500 engines on four-engined Image.Airbus A340-500 and Image.Airbus A340-600 aircraft, they were more than good and efficient enough.

I am of the opinion General Electric was not going with the GE9X engine in the same direction. In the order to make extremely efficient engine that will quality compete with the Rolls-Royce Trent XWB on Image.A350 aircraft, General Electric will certify those engines to the required thrust at their upper limit of the working area, where there will remain very little reserve of thrust and power inside them. To have an engine with the unused potential and a lot of power reserve means too heavy and uncompetitive hardware under the wings. And, nowadays, there are no more newly constructed overweighted four engined aircraft to compete with, but very optimised, fuel efficient and sophisticated A359s, A35Js (possible A350-2000) with the very efficient and modern RR Trent XWB and announced Rolls-Royce UltraFan engines. ..

You could ask: ' Why should all that reserve of thrust and power be needed, anyway? '…
Possible increase in MTOW … streched version of the aircraft… Besides, someone could afterwards reveal how their large fleet of Boeing 777X, because of the specific climate conditions and high ambient temperature, would need engines with the more thrust than it was predicted ? Wasn't there someone from Emirates, not so long ago, and who touched the problem of the lack of the thrust for 'their', once very actual, fleet of Boeing 787-10 aircraft, because nobody has predicted that, one day, someone will ask for 84 klbf of thrust from Image.GEnx-1Bs or Image.Trent 1000s for their Boeing 787 Dreamliner aircraft…

Trying to take out more thrust from the engine, already being at its limit, by further increasing of its working parameters (FPR, CPR, TIT and mass flow through its core), is almost impossible without compromising its reliability and durability. Increasing the speed of the GE9X's 134" fan, like Rolls-Royce did with the Trent XWB-97 engine, and which received the scaled-up core, could be problematic because the fan's too high circumferential velocities could cause very high centrifugal forces (proportional to the mass in the rotation) and those force's moments. Due to such increased values, mechanical stresses in the construction may affect the fractures and tearings-off of the materials... But, if the fan speed could be increased with the intent to get additional thrust through the fan, the core has to be scaled-up (that means reducing the BPR) or some stages on the certain core's sections has to be added (in both cases engine's mass increases). Or, you can leave fan's speed as it is and try to find additional thrust through the increased mass flow through the engine's core. How? By scaling it up. By redesigning the most of the engine, and that is not so easy. Nor cheap. Besides this way you heavily compromise engine's propulsion efficiency …

But, that is the risk of the designing of today's engines: if you want to have very competitive and extremly fuel efficient engine, this particular construction, very probably, will not be good enough and sufficient for significant thrust increase. Just remember how Rolls-Royce Trent XWB-84's construction was not sufficient for getting thrust required for the Airbus A350-1000 aircraft. I believe Rolls-Royce could have made from the first moment the engine construction sufficient to achieve the required thrust for the aircraft bigger than the Airbus A350-941, but how competitive and efficient would such a design, with the high power reserve and detuned to the required thrusts for A350-900, be in the comparison with the Image.GEnx-1B and Image.Trent 1000 engines on Boeing 787 and especially future General Electric GE9Xs on the Boeing 777X aircraft? Insufficiently. For a sure.

I find the architecture of the Image.GE9X engine (1F+3LPC–11HPC2HPT–6LPT) to be more similar to that of the GE90 engines with the 123" fan (1F+3LPC–10HPC2HPT–6LPT) than to the one of the larger GE90 engines with the fan of 128" (1F+4LPC–9HPC2HPT–6LPT), and which, in turn, is more similar to that of Image.GP7270 engine (1F+5LPC–9HPC2HPT–6LPT). Compared to the CPR of 19,0:1 on the 9-stage HPC of the GE90-115 engine and 23,0:1 CPR on the 10-stage HPC of the GEnx-1B / 2B engine, GE9X's 11-stage HPC's compressor pressure ratio is even 27,0:1, raising TIT by around 100 degrees.

We'll see how it will work, but very likely this engine could raise the ladder to its competition very high. Anyhow, I'm looking forward to the rollout of the first Boeing 777X flight test aircraft - the 777-9 variant; MSN 64240, LN 1567; reg. N779XW

Yep, that's what happens when you have the world's largest jet engine with the world's largest fan and the highest bypass ratio and overall pressure ever achieved, with the hottest core temperature ever put into service. The wing's going to be weigh more too because it's longer. All of this works because all of it delivers enough efficiency to justify the additional weight. If it wasn't, Boeing and GE would save themselves a lot of money and just keep building 77W and 77L.

It is assumed that the first flight (test) will take place at the end of 2019. But the current trend is toward smaller planes. It is cost effective and maximum demand. Boeing 777x - in any case, it will be cool and happy ...

How many options do airlines hold on 777X? With orders and options how close is it to the approximately 858 of 777L/W - not including the approximately 150 for 777F.

I'm sure an 777xF will come later.

The number of options BA has on 777X seemed surprising at 24 on 18 firm and just wondering if that relationship holds on the rest of the book - although it would be pretty impressive if EK ever operated 337 777x. (150 plus 187 options in the same ratio to BA).

First flight should be in the next couple of months, not the end of 2019.

I believe 778F will come much later because of higher OEW. With same MTOW, OEW of approx (my guess derived from 779 OEW of 400k lbs) 350k lbs means about 30k lbs less payload. Despite the longer fuselage. Only those with undividable loads (better on 748F) and light bulk loads would benefit.

Better to backfit the GE9x to the 777F, but time will tell.

They said the gauntlet test was completed. There is no more detail than that.

First picture of the 777X's flaps deployed (doesn't look like the slats are out, however).
It looks like even the inboard flaps are single-slotted, a la the 787, unlike the current 777 flap configuration some users said it would mirror.
Next flight: August 1: WN2002 BWI-MSY B737

Yeah, but don't sleep on the cool An124, cool KC-46, cool 727F and the cool 787 with a picture of Harvey Milk on the tail!

You definitely notice the 787 tail in this pic.....the GE90 looks a bit bigger,guess that's cause GE9x cowling is open....you definitely can see the aircraft is a bit longer than the 77W

That’s a nice comparison. I’m so looking forward to see this plane at gate with the wings tilted up! :-)

I wonder if they're going to try and have the first flight on June 12th, the 25th anniversary of the first flight of the original 777. Would make sense.

I think that waiting until June 12 would put the flight test program way behind schedule.

Mid April was supposed to be the first flight. Doubt the MAX issue should affect this progress...yet.

I don't think it would. The only impact might be a longer certification process. I think FAA would definitely make it longer now, and I would guess that might delay EIS by a few months.

Test frame 777-9 N779XW will begin primary flight control system ground maintenance testing, beginning with flight controls, electronic and auto pilot testing in about 5 hours time
