Boeing 777X Testing/Production Thread - 2020

JohanTally · Sun Mar 08, 2020 2:22 pm

In this article the it shows the 777-9 range of 8200nm and 9300nm for 777-8. I wonder if Boeing has already increased operational range or if this is a misprint.

Those figures are not believable. Misprint is too kind a word!

From Boeing's PR after the first flight:
https://investors.boeing.com/investors/ ... fault.aspx

Range:
777-8: 8,730 nautical miles (16,170 km)
777-9: 7,285 nautical miles (13,500 km)

There is a sentence of ‘depending on airline configuration’ so there is that caveat in the article but a bit of a dishonest one if it is. I think you need to go below 300seats to get 8200nm out of it ( which would be possible in very high premium cabins but hardly typical.

Not specific to the 777X but is there any record of the highest percentage of expected load any aircraft has ever experienced in flight?

Basically, how much margin over the worst case scenario is the 150% requirement providing?

As it suggests - 50%. The 100% figure is supposed to be the largest load the plane would ever see in operation.

What I mean is has any aircraft ever experienced forces over the design max load in flight that has been documented?

An example of being over 150% on landing, this is a Russian bomber, cue to about 1.10

I assume China Airlines Flight 006 would qualify as a flight that exceeded design max loads.

This would be an example of the frame exceeding limit load or 100% load.

Airframe break-up would be 150%. Not sure if this has ever occured as the only scenario I can see this happen is the plane trying to come out of a steep dive.

I believe hard landing is typically where you'll find he most occurrence of exceeding limit load.

bt

Yes, exceeding max speed by about 22% would hit 150%. Pulling up from steep dive, extreme turbulence, and hard landings all would be examples. The envelope is defined by event of scale within normal operations. Things like going supersonic, dual engine failure, takeoffs 15% overweight, CG outside of range, etc are outside of the envelope.

nycbjr · Fri Mar 13, 2020 2:41 pm

Any updates or has the CV slowed things down?

bikerthai · Fri Mar 13, 2020 6:32 pm

As far as any one is aware, there have not been any confirmed Boeing cases in the Boeing Field area where the testing is being done.

Not sure why folks have not picked up the news yet, but apparently they just did a rejected take off test.

Yes, I was waiting for the brake fire, but they cut off the video.

Isn't a wee bit early for rejected max weight take off?

The other question is did they deliberately popped the tires? At a minimum, they must have wore them down to the minimum thread to simulate real world condition?

I think that is one of the very final tests - given the potential for damage to the plane.

There is no way that was the max weight rto. I thought that test was at high energy speeds? It may have been a max autobrake rto however, who knows

CCA · Sat Mar 14, 2020 3:07 am

I'd imagine they were trouble shooting an anti skid auto brake / RTO issue that clearly led to a locked brake and blew the tire, the brakes would certainly not get hot at such a low abort speed especially the locked brake.

Could be related to COVID-19. Seattle is an epicenter and Washington State is placing more and more restrictions to try and contain the spread. Boeing has reported around a dozen cases with about 100 people quarantined for possible contact.

bikerthai · Wed Mar 18, 2020 4:50 pm

There was a post a week ago saying the first frame was down for maintenance as they will be installing additional test equipment.

While all who can work remotely have been ordered to do so, those who need to support production and the flight lines are still required to come in unless they want to take sick leave or vacation.

Belt tightening is in effect, so there may not be incentive to accelerate any work and everyone is being extra cautious.

Boeing Puget Sound is getting ready to shut down. They will start to wind down with closure on Wednesday. Not sure how this will affect the military side as certain programs were told they are important to military readiness. But things are fluid.

Anyway for 777 flight test fans, you'll need to find something else to occupy your time for the next few weeks

"Firing order" means the loading sequence of the frames, this has always been used for Boeing production lines.

Correct. I probably should have avoided such jargon but I presumed it was familiar to readers of this thread.

Basically I want to know how close we are to seeing more 777x roll out of the factory.

StTim · Sun Apr 19, 2020 4:04 pm

There has to be some nervousness about the number of "customer" frames that are being built when most customers seem to be wanting to at best trim their orders for the frame.

Googling found this:

Three more 777-9s, all of them currently on Boeing’s Everett flight line, will join the test fleet and be flying by the second quarter, Boeing says.

Ref: https://www.flightglobal.com/air-transp ... 88.article

So the first four are built:

Boeing can stretch production by lowering the rate.

http://www.paineairport.com/ is a great source, I should have checked there.

Nose gear doors say "ZB" which is not what I would have expected...

It suggests we're looking at:

L/N 1624 C/N XXXXX B777-9 A7-EZB? EMIRATES (WH010)

which seems out of order, or I'm missing something.

I saw no other markings on the plane.

I still love those folding wing tips, they look wonderful!

ILNFlyer wrote:

Nope, they are just so deep in the production list that the customer is not assigned or identified yet.

"White Tails" are planes built on speculation that customers will be found, and I don't think we will see the big vendors do that.

We do see "NTU" where a customer is identified at build time but then they back out, and frames built for testing that have no customer assigned, but I think these companies will not build without a defined customer or use before hand.

No, all are allocated to 777-9 aircraft and have a customer (and are/will be built according a customer specification), but no details are known yet.
