Was it ever made public if stuck up wingtips could be waived for flight? ( then both up, obviously )


I read your comment along the lines of: Was it ever made public if the aircraft waved its wingtips in flight?

Would have been a nice gesture for the occasion :D

I think the 777-9 is the coolest aircraft out there with the folding wingtips etc. The A35K is the most beautiful and was my favourite. But when I witnessed how graceful the 777X was for first flight and the wingtips folding in action automatically, it really just flew to first place on my list but of course A35K remains a close second.

Again, this is subjective. The aircraft that you love poses a problem for me at the tail cone and the "scrap metal lying around" behind the wing and on the fuselage ...

Wasn’t able to watch it live. I promised my girls to organize some junk food for Saturday night and they kept complaining and complaining why I would watch aircraft videos on YouTube instead of driving to the supermarket :roll: Finally I gave up...

Congratulations to Boeing! I think the 777X will have a great future.

By the way: Airbus congratulated as well, as usual, and got a nice reply by Boeing: https://mobile.twitter.com/airbus/statu ... 3024303110

779X makes the A380 look like the beauty queen. The 767 nose it has is still hideous as are those winglets when they are not extended. They are cool for sure but also ugly to an equal measure.

I noticed that too when I watched the stream earlier. All I can say is that the plane is definitely more on the lighter side even with all the measuring equipment i'm sure was on it. But more so, I was thinking when it happened that those wings must generate an INCREDIBLE amount of lift. Just as intended I suppose.

The innovative "semi levered gear" already installed on the 777-300ER has something to do with it.

If the front wheels are lifted upwards, this is not a fault.

No doubt that it was synonymous with the efficiency of the big CFRP wing also

Yes the wing seems to have performed quite well just watching the take off roll. I hope the 777x outperforms expectation

Actually they do but not until later in the flight. They first do some basic tests/evaluation on flight handling before changing the aircraft configuration (gear, flap setting etc.)

Looks like. minimal lift on front part of the bogies then the nose starts to lift.
both(all?) go up in sync .. then we see rotation. tail doesn't seem to drop at all relative the runway.

the plane isn't much above OEW is it? how is the stuffing? Instrumentation ( seen no pictures from inside )

Indeed. I was a little surprised to hear they auto fold on the runway once under 50kts. I’m curious if this will be standard procedure for all carriers? I don’t see an issue if you’re under 50kts, but an interesting setting none the less.


I think it’s built into the aircraft systems, it makes perfect sense so that the wingtips are up in time for a high speed turnoff.


Yup. There was a Boeing document linked on the site ages ago that had a section on the manual and automated bits of the wingtips. Unless otherwise disabled they'll automatically fold up after dropping below 50kts. And there's an alarm if they try to take off with them up.

The general idea being that only on or entering the runway are the wingtips down. All other times on the ground they should be up.


Thanks, I found that link.

I'm glad I'm not the only one who saw this. I thought my mind was playing tricks on me. What would cause that? I've not seen that happen on other 777s. My idea would be that it was lightly loaded, reached take off speed (or slightly higher) and wing was generating so much lift it pushed the body of the aircraft up slightly before the nose came up for rotation. If you notice, it had a VERY shallow rotation angle before the thing was off the ground.

I think the wing was responsible. Largest CFRP wing out there. I’m sure it caused so much lift on the aircraft

You can find Photo evidence of 737 MAX and 787-9 first flight over Mt Rainier with gears up. Wait few days an they will probably release one of the 777x over Rainier as well.

My only slight complaint is on aesthetics: I've seen pictures of her before, and with the folded wingtips she looks great. With the wingtips locked down she looks a bit... old style. Like an old 777, not like a modern, efficient and cool winglet design.


An an Old Aero Guy, every time I see a winglet, it looks like a band aid.

A fully planar wing will always have lower induced drag than a wing that has some of the outboard span bent up to create a winglet. The same applies to a 737MAX up/down winglet.

Jeremy DL @ Twitter ( https://twitter.com/photoJDL/status/1221271901378469896 ) seems to have a photo that captures the moment of interest

Looking at the photos in detail tonight, both main gear started tiptoeing off the runway before the nose did - though the nose was the first full set of gear to clear the ground:

My guess is this happened because the plane was light and the crew was trying to avoid a steep climb out.

Another Twitter thread ( https://twitter.com/adamspink/status/12 ... 3498641412 ) suggests they simply were being conservative on rotation speed VR till they knew what lift the wing would be generating.

Relevant FAA regs ( https://www.federalregister.gov/documen ... g-wingtips ) say:

The wingtips must have means to safeguard against unlocking from the extended, flight-deployed position in flight, as a result of failures, including the failure of any single structural element.

because:

Boeing has determined that a catastrophic event could occur if the Model 777-8 and 777-9 airplane wingtips are not properly positioned and secured for takeoff and during flight.

Oh they can afford it, but I agree with your general premise is that it wasn't important to them.

We're all aviation enthusiasts here, so we're excited to see her fly and want a fancy Dog and Pony show to accompany it. But Boeing's sole focus is to get her up and start the process of certifying the frame so it can start recovering all the monies invested in it.

The content was fine.

People should keep in mind that Boeing doesn't have first flights all that often so they don't have a staff of experienced people ready to cover every aspect of the event, they just grabbed Josh from communications and Emily from marketing and Ted from flight test and got the information out without spending a fortune. SpaceX does a similar thing on each launch and it works out just fine, and has the benefits of doing a launch every few weeks so they have honed their coverage over time.

If they did the opposite and hired a full blown production crew and professional on screen talent we'd here people complaining about how Boeing should just focus on building airplanes and stop wasting money on PR stunts.

Extending and locking the tips down is more likely than removing both tips. The latter is an option for the 7773ER so will probably be possible for the 777X.

With its current state, there is a general nervousness in employee faces, hiring professional crew (or) aviation vloggers is not a bad idea or use some young employees who is into vlogging or tik tok. If you followed SpaceX webcasts, overactive cheer-leading started after a failure.

Hi, OAG, nice to see you here!

Above I posted from the FAA special conditions document:

Revelation wrote:

Wouldn't this preclude any flight with wingtips removed, or are they worried about things such as the tips breaking off and causing further damage, or asymmetric lift?

Note that since the first flight was the first time many people saw the wingtips operate I think a wingtip discussion is on topic for this thread.

Also, any comment on the main gear lifting before the nose gear as shown by the photo above?

Finally a big positive for Boeing, Let's hope more orders come in for the 777X. Korean Air is supposed to be shopping for their next long haul jets. Air France & KLM have large 777 fleets and even though Air France has ordered many A350-900 they still need a 777-9 sized plane. The Chinese airlines also need more 777 for expansion even those many of their 77W are young.

During takeoff, it looks like the front pair of wheels of the main landing gear lifts off the ground before the pilot pulls up the nose.

I find that a weird observation and am interested in your thoughts on it.

It looks as if as stated above with the aircraft being at a minimal weight it entered ground effect quite quickly and simply wanted to fly , the pilots had to hold her off a little longer until the proper Vr speed I would assume .

Kinda glad we're talking about this rather than "damn, the thing didn't want to fly at all, it needed every inch of runway to take off".

The heart has its seasons, its evenings and songs of its own

Busby Berkeley and June Taylor were not available. It was the first takeoff of an airplane, for heaven sake; not an MGM musical or a TV variety show!

I will agree that the presenters were not very good, and much of the talk was to “make noise” rather than just let the images speak for themselves.

I personally don't care who they had making commentary. The helicopter shots were awesome. I shut the sound off on the live feed and listened to Live ATC feed. Was not particularly interested in what the host had to say.

By design -300ER does the same on the bogies, rotation pivot point bogie lock - reduce tail strike - danm looking good bird, a positive for boeing.

So? AA, DL and UA are the only US carriers that would conceivably order the 777X and all of them got orders in for the previous generation during the last decade. They aren't going to rush a new widebody purchase, and from Boeing's standpoint, entering the market with orders from international heavy-hitters like EK and LH isn't a bad place to start.

One can’t help but wonder what new system Boeing secretly installed to compensate for new wings’ aerodynamic tendencies. Got to keep the same type rating right?

Boeing has determined that a catastrophic event could occur if the Model 777-8 and 777-9 airplane wingtips are not properly positioned and secured for takeoff and during flight.


That's interesting. I thought they would have to certify the plane for wingtip folded up flight as well.

The A330 and A340 can fly with a missing wingtip/winglet. Including revenue flights. With both or just one missing wingtip.

That being said, the folded tip is a different animal.

It’s very much aircraft dependent. Some aircraft can (legally) fly with only one winglet missing, some can fly with both missing, some require both.

I think newer aircraft tend to require both winglets, as they are more integrated into the overall design.

Since it is a all new wing they can design it to give similar characteristics from the start, and the 777 is a full FBW aircraft so easy to adjust things as needed. You are not concerned about the 787/777 or A33/A350 having common type ratings are you?

Nothing to add except the wing itself. The 777-X has better lift than any other existing Aircraft...

And? I just saying with this being an American made aircraft it would have been nice to see at least one US airline supported on there.

Watching that take off roll, I can attest to that!

I commented yesterday that all of the aircraft seen either side of the 777X before it taxied out showed not a single US Airline paint scheme. I think there was one US military-gray aircraft among the bunch.

That’s because all the 787 that are rolling off the line for AA and UA are in CHS and the UA 777-300s that rolled off the line this year were already delivered. Also all the US MAX aircraft are stored elsewhere.
