Never worked with or on DC8 or B747, but never saw any steering on their landing gears. The steering makes it easier for the aircraft to make tighter turns, but you still see tire scrubbing but you see less wear of the sides of the running surface of the tire than for example the A350-1000 which doesn’t have steering on the landing bogey.
@@dennisvijverbergbrakesrele6098I am a former DC8 F/E, I confirm some series, the 30 and some 50 had this device ( I flew on one of them which was a 55)
Some of the early DC8 series aircraft had main landing gears where the back end would unlock and caster when the aircraft was making a tight turn. I remember on occasions, DC8 would be pushing back and one of the main landing gears aft end would unlock and wheels would go into caster. Tow crews would have to pull the aircraft forward and try to get the system to lock. I do not recall this system on the B707, but I did not work latter year aircraft.
Could you do a walk around of the main gear similar to the recent NLG video?! I had an incident many years ago, where a B777-300ER lost a bunch of parts on a runway during a severe winter storm. We were next to take-off and we struck many of these parts, resulting in a high-speed RTO. I have always been curious to have a look around the main gear to try and piece together where all these parts/wire harnesses were located on the aircraft, and how they could have been ripped off during their takeoff. Thank you
This bird had just landed at MIA from a 16 h flight from DXB and was getting repositioned for the return flight 5h later. Still a young 777-31HER, first flew on 2011-07-27.
The hydraulic fluid is test by a set interval, overall hydraulic fluid isn’t changed so far it doesn’t get contaminated. We just keep the fluid levels up. The actuator will be changed on condition ( do not think this is a system that is replaced on time, like the landing gear itself will be ). The actuator attachment points have inspection items according the maintenance manual, do not know where in the maintenance program this is checked.
Top video! Wordt alleen de laatste as van de 3 assige bogie gestuurd of ook de voorste as? Of draait de hele bogie in z,n geheel? Ik ben een leek hoor maar wel een enorme fan van de 777!
The A380 has also steering on the aft axle of the body gears. As in the comments some older aircraft had it too. B747 steers the whole boogie of its body gear.
This is not main gear steering like the 747 body gear steering system where the entire body gear assembly turns. The only thing that steers on the 777 main gear is the rear axle.
Thanks for sharing this was interesting. Videos like this will help the youger generation who maybe can't qualify as a pilot but still want to be involved in aviation.
The rear like plus axle like a steering is what sterilized the flight upon landind in other words on final retardation to the ground ones it stargers then the front starionary tire on the same line immediately regulate its control why the flight is still on landing motion not to make the plane lost its stability... by klems 😢
Sir you can not stear the aircraft we have a by pass pin in place . Your not telling the full story to the Viewers --- WHY ??? 😂 by pass pin means the nose gear is locked you can not do anything with the Stick the only thing steering the aircraft is the tow truck and the tow Bar connected to the nose gear .
@@RayhanAhmed-qr3vz indeed, but main gear steering follows nose gear steering angle not the input made in the cockpit. So when to tow truck changes the angle of the nose gear the main gear steering will follow.
this is so awesome! the stress this gear has to withstand (not gentle landings lol -for full bore front nose gear hits occasionally, or cross wind loading? I have personally inspected gear made by Liebherr, Cessna X10 (made by Textron group) - all are amazing for the shear weight savings and ability to withstand the enormous loading that occurs!
The screen interfaces still look modern for a plane that first flew over 30 years ago. Unless the ER has newer graphics but that's 20 years old now too
The AIMS system of the B777 has had some upgrades during the last 30 years. Newer versions definitely have upgraded versions, so suspect the graphics have been improved since then.
Absolute eye-candy. Could not take my eyes off of the video. I may have to moonlight as an aviation tech. The 777 was the last great commercial aircraft Boeing ever made. And before that, the 747-800, 737-400, and 707. I'm all Airbus now.
@@brodricj3023 the experience I have , is like with a bogie that is none steering, like A350-1000, you see a different kind of wear. Not sure if they are replaced faster
This is a really well done video Dennis. You certainly capture all the key points of the system. It certainly looks a lot easier to work on than the B747 body gear steering systems.
Boeing build very good quality planes. Until the one on top becomes greedy and decided to take short cuts on the quality control
@@passqua hopefully they can change it around and make again good aircraft like the B777
I had no clue they could steer. Impressive.
Me encanta ver tus vídeos 🇨🇴👍 ver ese mecanismo ❤
I think that the DC8 and late model 707 had a similar set up on the rear bogies also to help stop tire scrubbing on turns also

wow! thank you and safe skys!
how "old" is the hydraulic-fluid ? ...and the changing intervall of the endlagendämpfung (kolbenstange / kreisring) at this stearing-zylinder ?

Hi, alleen the laatste as stuurt me, de hele bogie is alleen op the B747 body gear.
Thank
It's funny being need better tyre and wheels than wing
Is this unique to the 777?

I guess since the turning gear alone costs more than a house. And there's two of them
hai i'm from indonesia
Finally got to see how those main landing gears articulate. Thanks so much for sharing
No problem 👍

Still love the 777-ER Series. A true classic.

Always welcome
Thankyou Dennis, I always look forward to your "behind the scenes" aviation videos.
Glad you like them!

Smart way of achieving push-pull action using only one actuator.
Is it only the one pair of wheels on the MLG bogey that pivots?
Yes only the after wheels on the bogies are steering.
@@dennisvijverbergbrakesrele6098 Do the non-steering wheels tend to wear out quicker than the steering wheels?

Thank you, if I ever get the chance I ll try to show the B747 body gear steering to.
Great! Can it be used as parallel steering for sideway landing in heavy crosswinds? Some plane lands at 20 degrees or maybe more.
Hi, no it’s only used on the ground. Cannot be used during flight.
The B52 can do that since the whole bogie turns
Ух-ты,даже стоит продольная диагональная тяга,прямо как на тележках скоростных поездов ТЖВ!
That is an interesting linkage setup.
AMAZING!!!!!!!!!!!!!!!!! Tx for sharing!!! :D
Boeing being Boeing

Thanks for sharing this video ❤❤❤
My pleasure
Its crazy to think boeing use to build good planes
Thank you for taking the time to record and upload this video.
Best video I form india🇮🇳
