Boeing continues to accumulate flight certification hours with their 3 test beds. This video shows Boeing's Third and latest new airplane the 777-9X (Reg# N779XZ) -set of Taxi tests, Engine vibration and noise tests, Wing and Horizontal Stabilizer (HSTAB) flutter with maximum engine idling thrust, wingtips folding/ unfolding and finally take off @ Paine field Airport, Everett, Washington (KPAE/ PAE).
The main purpose of this test was:
1. Engine spooling, vibration and noise dBs tests
2. Wing and HSTAB flutter tests under maximum thrust load
3. test and verify airplane systems andflight controls.
4. Taxi test at various speeds
5. Raked wingtip folding up and down
6. Take off from runway 34L

Happy planespotting!!
Really love how smooth the engine sound is!
What a simple, understated but decent design.
it's got a weird forehead though
The original 777 was the most boring sensible aircraft Boeing had ever made when it was built. Hopefully the new iteration will continue the legacy!
That spool is amazing
Seeing the horizontal stabilizers lateral flutter it was obvious that it was a very windy day, but after waiting through the recorded sound of the wind, it was certainly worth the wait to hear the sound of the engines spool up on the newest generation of the 777, then hear it and watch it roll for take-off.
Looking at the windsock, it doesn't look "that" windy.
Loved the way the tail plane was rocking about 2:40
Yeah thats the flutter test- to make sure structurally it does not resonate to its natural resonance from the engine vibration and does not result in any structural failure
@@dipankarbhakta8 Thanks for the explanation. I appreciate it.
@@dipankarbhakta8 Awesome capture! May I feature the part of the wing flutter in one of my next episodes? Of course with a link back to your original video. Cheers!
ok, I'm here for it.
The really stand out item on this aircraft are its engines, biggest in the world and a leap forward in regards output and economy- GE 9X Developed by GE and NASA
Paine field must be a wet dream for Boeing plane spotters.
Lufthansa‘s future D-ABTI! Beautiful aircraft, can‘t wait until it will enter service
Какой красивый самолёт какой красивый полёт прямо аж душу завораживает
Since I flew on 777-300ER last 2016, I wanna try this best modern plane the 777-9
Well... finally Jumbos are not finished like everybody was expecting..by the time this baby is certified ,the A380 will have claim his crown back....Emirates just ordered two new Airbus 380 with new interior design ,British airways and Singapour also , and it"s killing it as a super cargo plane.
I appreciate your optimism, but Emirates had four Airbus A380's left to be delivered, and that's when production ends on this model. These are not new orders, but new planes already on order, outfitted with the new interior. The same goes for British Airways and Singapore Airlines. They are putting new Interiors in their older A380s. When Boeing delivers the 777x in 2023, it's efficiency alone will make it harder for any of the quad jumbo Jets still in service. Doesn't mean however, that the 380's, will not stay in service for years to come with a handful of Airlines.
The only reason the A380 is serving as a super cargo plane is because the cargo consists of masks and PPE, which are relatively light
Sounds like the a 787 on steroids! Awesome video!
😄
😭😭
Boeing will be back with a banger. We need a new 737 and a 757 replacement
Wow too bad you didn’t capture the landing too, but it was awesome footage
Wow. Great plane.
She's beautiful.
I believe there's talk of cancelled orders due to delivery delays
The global pandemic brought the whole aviation and airline industry to a slowdown.....
Delivery delays are due to other airlines deferring deliveries
No it’s because of certification issues relating to the 777x.
Great video. ☺️ I still prefer the original Boeing 777's with the GE90 engines.
Still better than using RR engines since RR engines caused some 787s to be grounded. And don't get me started on Pratt and Shitney
The original 777 rarely came with ge90. The second gen 777 had exclusively second gen ge90
@@aseem7w9 I’m just talking about the Boeing 777’s in general with the GE90 engines before they made the Boeing 777X. By they way, a lot of the original 777’s had GE90 engines like the Boeing 777-200ER’s with British Airways and other airlines.
@@joshuahalla.k.a.controlla6333 the 777-200/200ER only came with first generation ge90 tho. They have smaller fan blades, look uglier, less efficient and less powerful too.
Also ge90 on the 772 were the least popular engines.
@@aseem7w9 I’m talking about the GE90 in general not a specific type of the GE90’s. What I’m trying to say is that I prefer the GE90 as a whole compared to the new GE9X. The GE90 is way better and most people know that.
If it ain't a Boeing I ain't going!
huge engines👍
Does anyone else here want to see what the 777X's contrail will look like or is it just me? Because I really wonder what its contrail would look like, especially compared to the contrail of the regular 777.
the condensation trail (contrail) at cruise, that originate from the engines, would be very similar.
@@ghostrider-be9ek It would look similar, but bigger.
@@ChrisZoomER the engines operate at similar temperatures and pressures - how would the contrail be bigger? the condensation is a byproduct of internal turbine engine combustion (which also produces water vapour) and not related to the bypass air flow
@@ghostrider-be9ek The engines are more spaced out from one another so the trail would be wider.
@@ChrisZoomER im not sure how that makes it 'bigger' but ok - also the engines are not that much further apart - do you happen to know how muhc more thanb the 777 ?
So quiet
3:10 look at the vert & horiz stabs undulate! RC planes do that. Don’t think you can’t your jumbo jets doing that. Sheet.
Get a wind muffler
The large fan sound like propeller
THAT'S A SMALL WING TIP, WHY EVEN BOTHER? Just make it a sharklet like the A350, simple and with no moving parts to break.
The wing tip folded on the -9X is the same size as the 777-200, -300. so it will fit in the same gates as the older 777's.
For extra wing span and best efficiency
@@mikeske9777 the 777 200 and 300 had slightly smaller overall wing span than 200lr and 300er
Those wings look flimsy
Engine is a ziller
Este avión de tantas horas de volar para su certificado, no ha podido hecharse un vuelo a Europa todavía. Se ha quedado estancado en circuitos de su misma periferia.
A UFO.
I will say the 777-9 will be its longest range in the world
Mwhat a beautiful airplane. It's to bad that the biden administration is killing any need for such an aircraft. In the future air travel will be so expensive that only people with means will be able to afford it. Fuel prices and the price of raw materials to build these will drive prices beyond comprehension.
This baby is being hyper scrutinized by the FAA…will. it be allowed to fly until 2023
Has software issues that caused it dive again
Definitely not flying Boeing’s new aircrafts.
