It was definently a smart move to incorporate the folding wingtip, given how it'll prevent the same changes at airports that were caused when the first 747's and A380's arrived.
It wasn’t too much of an issue with the 747 vs the A380 as it fitted in more airports than expected but in case it didn’t most airports were willing to make the upgrades because after all the 747 brought the age of the widebodies whereas the A380 should’ve been designed to work with what we have as airports now are no where near as willing to upgrade without lots of valid reasons as even with general expansion it’s just for getting more of existing sized planes which by and large won’t really change now
@@filledwithvariousknowledge2747 That is true, but on the subject of the 747 and A380, have you seen the news about them being turned into hotels and rental party locations recently?
Fun fact, the original 777 was also meant to have folding wings so it could fit into 737 gates. It was much more complex as there were control surfaces and systems outboard of the fold. Sadly no airline ever purchased the option.
Boeing 777x wingtips are so cool. Folding wingtips so the plane can fit into smaller airports is an amazing idea! The 777x is bigger than the 777-300 and can fit in the terminals and gates in which the sister plane can fit. I am so excited for the 777x to come out. I want to cruise the skys in that marvelous aircraft, I haven't even gone on a 787 yet!
I don't know what it is, but I find aircraft that change their shape really interesting. The Concorde drooped nose, Tu-144 canards, B-1 wing (and all variable sweep wings really) etc.
Correction. With the wingtips down the 777-9 has slightly larger wingtips than the 747-8 but smaller than the a380. But all three are in the same catergory.
Quick Question: when the pressure of the air hits the wings of the aircraft, it could damage the wingtips moving function. This could mean more breaking parts and more costs for the airlines.

@@wasmiddelsap3379 I want to see the future 787s have folding wingtips to fit 767 gates as well :), so as A350a improved with its own folding blended winglets as well if wingspan extends
I won’t be surprised if new big narrowbodies the size of A321 and 757-200 have them for optimised efficiency in cruise but also to fit in existing gates. It’s a major step forward for commercial aviation even though for military/navel it’s nothing new and considered old school by their standards
*A very Clever idea, and something Airbus should've thought of for their Behemoth A380 that's run into things a few times,* *and is limited at airports because of their great wingspan.*
well is too late now, the superjumbos 4 engines era is coming/come to an end. More small and boring planes are coming. Define when I get to my 80s this will change and aviation would not be the same. Lest hope all the 777x is the the last giant.
With the folding wingtips, the 777X will be able to fit into a lot more airports, because there will be no heed for any gate adjustments, like there had to be for the 380. The 380 is so big, and requires so much room, that there are very few airports capable of taking it on. And the wings are way cool! Of course, the Navy has had jets with folding wings for decades now. Bout time the airline manufacturers looked to the military for some inspiration!
Navies are prepared to accept increased weight for the convenience of folding wings for storage on board the aircraft carrier. The bean counters at airlines will be less likely to accept such weight penalties or loss of fuel capacity.
*There's Sensors on the Aircraft that will Reject a Takeoff beyond 50 **-mph-** Knots if the Wingtips aren't lowered to Flight Configuration.* *So the Aircraft will be Forced to Go Around on the Ground and Taxi into position for another Takeoff. Upsetting all involved.*
I like how Boeing incorporate the foot wing tips for the 777X I think it’s a very smart move argue with other people comments that makes it easy for airlines to incorporate this aircraft into airports that’s already been built to handle the triple seven arm oh generation family on that note I really do like her old before takeoff the set the task of forwarding the wingtips into the takeoff position down to the pilots and I like how they have the checklist started so oh yeah I like that hopefully they keep moving towards certification and make this aircraft the safest aircraft ever made
The wingtips are meant so the plane could have a longer wingspan while flying. When they are extended it doesn't create an air vortex at the edge of the wing. When this air vortex happens, it creates drag and drops fuel efficiency. They had this same problem with the 747-800 which is why they incorporated new wings for the aircraft!
*The Pilots, and many onboard, will likely see with their own eyes if the Wingtips are Lowered for Takeoff.* *I would imagine there will be a Green Light Signaling Locked Wingtips, similar to Landing Gear Lights are up or down, and locked.*
*The New Wing on the 777x is Designed to REDUCE DRAG and INCREASE LIFT for INCREASED FUEL EFFICIENCY,* *and LOWER LANDING SPEEDS for a SOFTER LANDING, for the 426 Passengers in a 2-Class configuration.*
That is sharp. But I looked closely as they level downward and noticed light fluttering. I hope that the system is perfected in avoidance of a recall. If Airbus followed suit, you can almost guarantee that their mechanism would be better.

Nothing should happen as the wingtips don’t produce too much lift. The aircraft can safely fly without them as they’re mostly there to have a higher wingspan and improve fuel efficiency.
It is a great design. However, I wonder how would it be when the folding wind tip have problem. Like unable to fold after landed or unable to extend before departure. If MEL/CDL can deal with the problem, otherwise it will need to AOG to fix it. Maybe Boeing can input a manual wind tip extension/folding (like the cargo door), so that engineers can extend the wind tip at gate to let the aircraft fly back to its hub without AOG at out station.
Yeah I am thinking about that too! Is it crucial to flight or just degrades performance when folded? We've seen numerous accidents due to pilots ignoring error messages on the screen.
@@MSRTA_Productions "to avoid any disaster" There are interlinks and confirmation checking but IIRC. Taking off with them not unfolded will be checked during certification.

just curious if the folded wingtips could act like winglet.. but when you see the hinges mechanism of the wingtips, you know the folded wingtips cannot stand such a high force from cruise speed...
I’m looking forward to fly 777X, I flew 737-700/800 for 10 years,then the 777-300ER,both 737/777 are very good aircrafts,very safe very stable, we used to make fun of the airbus pilots “as a man,you need to have a stick between your legs ”,anyway I hope 777X won’t let me down, Boeing can do better
Even with wings folded it won’t fit in the wings of UPS’s Worldport. 747s already have to be in their own parking. I don’t think UPS will get it mainly for that reason.
I feel those gates would be more expensive to occupy and cause a headache for SOP's. Might just be best to fokd wingtips on landing to avoid accidents regardless of the gate being used
When an airport has a width restriction it will be from the moment it rolls off the runway. It's not just the gates it's also the taxiway width restrictions. It may fit the gate with tips down but it may clip another aircraft on a neighbouring taxiway if they remain down
@Simple Flying.... Why on earth would you let the jet accelerate down the runway before ensuring the wingtips are locked in position? Boeing should have a dedicated Take-Off mode selector that checks that jet is in the proper take off configuration before the jet starts to move down the runway.
That's the job of the pilots, as there already is an option for an automated fold up for the wingtip when decelerating below 50 knots, but when taking off, the pilots are in charge of folding the wingtip down.
The difference is that the tech on the 777X wingtips has been in use since the War years, so it's not new for aviation, but new for a commercial aircraft of its size.

Sorry but there is nothing unique about folding wing tip. Aircraft that are based on carriers have been doing this since the 1930s. If find what airbus did withe the A380 much more intresting because the managed to make a heavier aircraft using existing maximum dimensions to fit within existing infrastructure without having to resort to folding any part of the aircraft.
Why would there be a rejected take off? The wingtip is not a lift device but a drap reduction or efficiency device. Whether vertical or horizontal there shouldn't be an impediment to achieving lift of course the reason could be the hinge isn't the strength point but the locks are and if not engaged they would rip off.
