I would presume that an increase in cruise speed would entail more work than is sensible for Boeing... A difference of a Mach 0.01 in cruise speed is purely for marketing purposes anyway. For London to Sydney, that equates to just around 13 minutes less cruise time at 35,000ft.

Internally there is not much to see - the cabin is full of engineering stations and ballast tanks.

It's a billion dollar program with customers all over the world. Why not share the progress on the program?
Is this again about the FAA and not putting anybody under pressure?

Almost assuredly not the latter.

It's just how Boeing does these things. The 787 and 737MAX flight test and certification programs were similar - Boeing issued press releases as milestones were reached, but did not spam their social media platform every day with updates.

You can be sure the customers are being kept in the loop, just privately and under NDA.

Cockpit looks like a nice future office. I bet a few guys I know at British Airways will enjoy their last few years on the 747-400 and then enjoy the transition to the 779.

I don’t understand why you’re so desperate for news every single day. It’s an upgraded 777 with new engines, wing and cockpit. Boeing is approaching this no different than any other program. They will share milestones and etc but they’re not going to be all over social media blowing up about the test program. There is currently only 1 test aircraft flying and it hasn’t even flown 10 times yet. Patience.

Boeing management is not much into Twitter. You don't want to listen to them on social media.

The company does a better job of puting out slick videos of their product. But it does take time to edit them. Just look how long it took just to get the internal first flight out.

Great photo's :bigthumbsup: It's huge.

“We’re taking the lessons learned from the 737 Max and applying them to the 777X to ensure we are as prepared as possible for 777X certification,” Boeing says. “Given the unknowns around development programmes, as well as the certification process, we do not want to be overly specific about hours of testing or timing.”


777 DERIVATIVE
Boeing says it intends to certify the 777X as a 777 variant, not an entirely new aircraft.

That could enable the 777X to take “credit” for some validation work performed by the first-generation 777, though the extent of the 777X’s updates likely mean such credit would be limited, says Lemme, who himself participated in flight tests for several Boeing commercial aircraft.

If I had to give a best estimate IES: late 2021, early 2022.

~ 1 year-15 months for flights tests.
~ 2 Years to rework, satisfying EASA, Emirates, Japanese concerns on grandfathering design and certification on a mostly new aircraft.

If they were able to certify the original 777 is less than 12 months, why couldn't do the same thing here even if they decide to re-certify instead of grandfathering? Are there that many new things since 1995? Why can't they add more aircraft to the program to speed that stuff up? I don't get the hate here. I'll admit I haven't read the JATR report so maybe its adding a bunch more items to the certification regime.

Make an overstatement and argue from there. ( Schopenhauer #?? )

You are aware that the FAA lost quite a bit of standing across their global peers?

JTAR recommendation are the condensation of international authorities ( not excluding the US ) thinking
and how they view FAA past activities.

There are a few differences with the 77W certification basis:
- new composite wing, dimensions, tips
- new engines, engine pylon
- new landing gear
- new control, fuel system etc.
- new fuselage (bigger windows, door locations, lenght, ribs)
- tail bigger surfaces , new vertical stabilizer
- new cockpit 787 style

FAA accepting the 77W as certification bases showed a surprizing flexibility. The JATR (FAA, EASA, CAA, etc.) recommends against this approach. Lufthansa is launching customer, EASA approves 777x for service.

? No hate, sticking to the rules after cutting corners with many victims. The CEO is out for not understanding, setting the right priorities, putting on pressure.

The airlines indicate they want a thouroughly certified aircraft. That can be done. But takes time.

I mean, the 350 took about a year to certify as a new aircraft (from first flight). Why will this take two years? I’m really confused even with these recommendations which don’t seem extremely specific. Ultimately I think they said the certification process is fine but it just needs some improvements. Also, my given the differences by optimistic prediction is Q2 2021.

So to be clear, you are comparing grandfathering of a FBW a/c to another FBW a/c with the 737NG a non-FBW a/c to the 737MAX another non-FBW a/c?
Ok, understood.

Anything "new" or "changed" on the 777X compared to previous 777 family members will need to undergo new certification under existing FAA procedures. They cannot be "grandfathered in" or "conveniently ignored".

JATR's recommendations are just that, recommendations. If and when they are incorporated into the formal certification process (in whole or in part) will be at a future date agreed upon by the various major certification bodies and likely the ICAO. If the suggestion is they should be retroactively applied to the 777X to "ensure maximum safety", then we should then pull the airworthiness certificates for the 787, A350, A330neo and A320neo and make them all go through them, as well, before those certificates are re-approved to ensure they are also "as safe as safe can be".

EASA is on record saying they will concurrently certify the 777X with the FAA. To my understanding, that means that their own staff will review the test results with the FAA staff and sign-off on them, but I have heard nothing stating that they have their own unique certification plan that Boeing will have to follow in addition to the FAA's. If they do have such a plan, then it has already been communicated to Boeing and their testing protocols would have been modified to take them into account. That Boeing has not said anything about an extended certification requirement from EASA (or any other regulatory agency) is strong implication such a requirement does not exist as it would have a material impact on Boeing financials which they would be required to state.

Emirates says they want an extended test campaign, which is different from an extended certification campaign. Boeing and Emirates will work that out between themselves using customer frame(s).

But

waivers will be frowned upon. If FAA does not do the frowning under JTAR "guidance"
the other cert authorities will do the frowning. ( and potentially deny certification.)

How does Boeing address that, has the FAA put that frowning into writing so that Boeing will not be denied certification?
Or do you believe that only Boeing has to provide documentation for others to follow? Even EASA had the decency to put their MAX requirements down on paper

Par13del, point out where I said that.

“We’re taking the lessons learned from the 737 Max and applying them to the 777X to ensure we are as prepared as possible for 777X certification,” Boeing says. “Given the unknowns around development programmes, as well as the certification process, we do not want to be overly specific about hours of testing or timing.”

“The certification process is a new one and it’s going to get applied to every next airplane,” Calhoun said. “We have a lot of planning to do around the 777X, et cetera, to make sure that we can accommodate a really thorough review and investigation. It’s just the way it’s going to be.”

I agree with Boeing.

There is a new process, unlike the 737MAX process. Lessons learned.

No use looking the other way & hope it goes away. I'm confident a safety first certification approach will be followed by Boeing and authorities. Things changed.

I mean, the 350 took about a year to certify as a new aircraft (from first flight). Why will this take two years? I’m really confused even with these recommendations which don’t seem extremely specific. Ultimately I think they said the certification process is fine but it just needs some improvements. Also, my given the differences by optimistic prediction is Q2 2021.

This.....agree 100%
Not sure how our Dutch friend conflates things to:
~ 1 year-15 months for flights tests.
~ 2 Years to rework, satisfying EASA, Emirates, Japanese concerns on grandfathering design and certification on a mostly new aircraft.

I agree with Boeing.

You then took quotes from the CEO to add how many years to the 777X certification?
The head of the FAA told the previous head of Boeing to shut up, after the current head gave his investors the timeline of summer the head of the FAA repeated his demand then rose Boeing shares by saying RTS may be sooner, he repeated that in the UK with the same result.
Now you are taking the words of the head of Boeing as if he is the one setting the new certification requirements? So back to Boeing self certifying?
Boeing screwed up its risk analysis, they have a lot of work to do to regain trust. The FAA screwed up their oversight, they have to provide details on their new certification process if and when they are ready to roll it out, until that happens, we are all speculating, at least some of us waiting for details versus running off the reservation.

Par13del, point out where I said that.

That does not explain a forecast for 2 years of rework. It may indeed mean some requirements are not accepted as met based on the existing planned tests, but it also does not mean major new design requirements that Boeing is unaware of and would as a result need to perform extensive rework in order to comply with.

That said, the 12-15 month test program you forecast isn't really in contention. It's basically the baseline schedule.

What will be the cabin pressure of the 777X on cruise? 8,000 feet like all other 777s or 6,000 feet like the 787s?

Thought I read recently planned certification by years end and deliveries begin first quarter 2021.

Keep the thread on topic. Its about the 777X testing and production not about the 737MAX. Users actually come here to see how the aircraft in performing in testing and its a bit hard to follow it with the mindless blather that has been posted in this thread in the past 24 hours

Seems like she’s about to land in Spokane. Why would they land there?

Yesterday’s flight test was scheduled for Spokane but they did a regression test instead. I’m not particularly sure what the purpose of this test is but I just know it’s a test

EDIT: it’s a go around test
