How does FLY-BY-WIRE work? The future of flight controls! Explained by CAPTAIN JOE

Didn’t expect to find an air-cooled Porsche in a fly-by-wire video.

"This is not an airplane, but my car" That Flex

Legends say that the interview with the Concorde pilot must be released at some point.

You are the reason that i want to become a pilot

11 years ago today, the "Miracle of the Hudson" was successfully pulled off ❤️

That feeling when I see it’s been posted 32 seconds ago

Pilot: 'disconnect autopilot, I want to fly manually'
Airbus: 'I cant do that Dave'

Btw, Concorde! Was the first jet civil aircraft to use “Fly by wire” not actually it but very very first version of it
P.S. Just realized Joe said it in the end of the video

Joe we need to see your cars. That’s a sweet Porsche

please do a video on airbus flight control laws as well (normal, direct and alternate)

I'm a student pilot and today, in my class, we actually talked about the fly-by-wire technology in Advanced Instruments subject. Your videos are not only interesting for people seeking some random learning but also very useful for pilots by recalling it! Cheers from Portugal, keep it up, Joe!!

Great video as always! Would you consider making one about how pilots navigate across oceans, particularly before GPS?

Does Captain Joe miss Airbus already???

My wife and I fly couple times a year. Since watching your videos I sit in my seat thinking about the subjects you've covered. Pretty cool! Thanks for sharing your amazing amount of knowledge and my hats off to all the pilots up there!

Thank you, Joe! Your videos as usual are clear to understand! Greetings from Ukraine!

I wonder what becomes of Joe's face everytime he sees an A320 while in the cockpit of a 747.
Cheers, Joe

Now this is the topic I’ve been waiting for! Thanks for the great content Joe!

Great aviation vid Joe. Keep it up! Also thanks for doing my suggestion for a vid! 😁

Another awesome and informative video Joe!! Keep up the amazing work and thank you for taking the time to bring u these videos!! Hope you and your family are staying well and safe during these difficult times

Nice job. Retired mechanic here--not many people realize that the Boeing 737-100 and -200, introduced in 1968 and 1969, had a basic but very functional fly-by-wire capability built into the SP-77 autopilot. With the autopilot engaged in control wheel steering mode (CWS), the control cable input lever on each flight control power control unit was locked at neutral and resisted any movement by the control cables. The force applied against this resistance was detected by force transducers mounted under the cockpit floor. Electrical signals from the force transducers were sent to the autopilot roll or pitch analog computers, processed with rate and angle limits, and output to the PCU servo valves to move the appropriate control surface. When the pilot force was removed, the computer either held the present bank or pitch attitude, or returned the aircraft to straight flight, depending upon sub-mode engagement. Watching the pilot fly the airplane in manual mode versus control wheel steering mode, it was normally impossible to see any difference in the pilot actions and results. By observing the autopilot engage switch paddle position, you could see whether the pilot was flying the airplane in manual, or utilizing the benefits of the electronic overseer. For its time, the Sperry SP-77/Boeing flight control system was nearly perfect.

Great introduction! As an aerospace engineer I hope there will be further videos explaining why FBW can be safer than mechanical systems and how a FBW system can detect damaged components and can still continue in normal law.

I love this pilot of pilots! He brings the depths of aviation right to your eyes. 💛🙏🏼

I did something vaguely similar; I drove a brand new Discovery around an off road course; brilliant! Buttons, bells and whistles, all mod cons. I then drove an old Defender. I ordered the Defender. It was old, clunky, required definate arm and leg input, but you could feel what the terrain was like and where the Landy wanted to go.

This is something I’ve always want to know

Not a minute ago I was binge-watching your videos, and suddenly I got the notification.
Believe me...For a second I thought youtube was spying on me

That is pure gold! Thanks for all the knowledge!

Thanks Joe, I’m working on a qualification project (EPQ) in college, regarding the automation and technological advancements of aircraft from 1912- the future, this will certainly be a good source of information for the segment on fly by wire controls! Keep it up :)

Been waiting for a video about this for a while. Really well explained. thank you

Thank you very much for making this video...I have always been confused with the FBW system. You’re like a aviation teacher god.

Hey! Thanks for explaining that.. I always wondered what that meant 😃

I had a general understanding about the system but yoour explanatiion went into way more detail (compensation and stuff), thank you!

Advantages and disadvantages are quite right and objective. I really like your videos. Perfect.

Fantastic video loads of info we are always learning..im wired

What we all have been waiting for without even knowing it

the explenation.. so clear as water!! keep up the good work!! 👍😊

Not a pilot but always curious about this incredible machines work, thanks for always giving clear information!

Fly by wire is truly interesting

The future is here😁

Awesome video love the March keep up the great work

Thank you ! Υou are understandable, very good presentation!

Another great vid joe!

You are my most favourite KRplusr🤩🤩🤩

No one explains stuff better than you Captain Joe. I appreciate you

great content on this channel!
As a pilot, I would love to see more cockpit vids showing CRM during departures and arrivals with checklists run etc etc
Thanks!!

Hey, can you please make a video on the touchdown zone/aiming zone, explaining where pilots are supposed to land and when the gears should touch the runway etc
Thanks, your videos are really informative!
Also, why don't you use a custom channel URl lol

Question for joe: Do you think the airbus cockpit is easier to fly than the Boeing (in terms of space and comfort)?

Joe, what an amazing video.
I’m an Aeronautical Engineering student at the German military university in Munich, to become a military pilot.
Basically, you just summarized what we had as an introduction to instrumentation and control engineering. Our professor used to work for Airbus and therefore he took the Fly by wire-system as an example to explain how control loops work.
I’m amazed that you addressed so many details in a video that is not primarily intended for engineering students.
I think your content is extremely helpful for anyone seeking to deepen their knowledge in aviation and I’d be lying if I said that your educational and motivational videos hadn’t been very helpful to myself to keep on going when university gets tough.
Thanks for your awesome work!

Very nice video, Joey! Glad you inspire young people for aviation! 👌🤗

"Der Mann hat Geschmack" Nice little Red Machine in the beginning and great informative video as always!

No please captain don't put a video online when I've an importante school teste to revise for tomorrow 😂

we are always enjoying with your clarification . Many thanks capt. Joe

I appreciate your very clear explanation and also the work of all engineers who have developed the system.

Hey Captain, hope you are well!
I was just wondering, are there any major differences between the fly by wire system and the CWS (Control Wheel Steering) autopilot mode on a Boeing aircraft in terms of flying characteristics?
Thanks, Jason

I'm not sure but I feel like you wanted to show off with your Car ;)
Greetings from Hamburg!

Thank you so much captain joe for your videos is very great.

Thanks. That was super clear. I always thought fly by wire was talking about the shape of the wings in relation to the tail.

Now I want a video on your car!

I like how he says "little cessna"
I would love to see a big cessna

Fabulous video! Superb animation and delivery ! 😃👍 thank you!
Nice Porsche !

You helped me a lot with a flight tech school project about ATA 27 group (FCS). Thanks a million.

I didn’t know I was this early

Captain Joe and Sam Chui collab maybe?
Maybe that's already a thing IDK

Very well explained. Congratulations and have a great day.

So spot on explanations. Leaves me out of questions. Everything g so clear, I’m just an aviation geek.

Also here's a suggestion: MFS2020 747-8 landing challenge.

1:52 the acronym had a typo lol

This is the reason why I started following Joe years ago. This is pure classical Captain Joe stuff. Fantastic work. Looking forward the next video, as I do wondered during the video « what happens if the computers fail? ». Thanks Joey.

Wow!
Thanks so much!
For this valuable information!!

omg this seems scary to me.. how it could fail seems like less control of aircraft I know they got that backup but relying on signals... scary haha

1:54
Isn't is supposed to be "FBW"?

Finally I get clear what FBW is and how it works! Thanks a lot for that Joe!

Thanks again for an interesting video! I just had an online session with a real pilot organised by a career event which was recommended to visit by my high school. Was definitely a very informative evening!

1:54 - Should that be FWB or FBW for Fly By Wire ?

I think I’ve never clicked on a video this fast :D

A good video, a lot of tecnical information . Thanks

Thanks for the effort you obviously put into presenting this Capt. I honestly found it truly fascinating, however, i'm very much looking forward to the video you said you were going to do on what happens if all this technology suddenly goes wrong. Happy New Year and stay safe.

I was literally thinking about u 30mins ago

I know this is an immature joke but I very young so I was like, Wut da 5:25

Großartig erklärt, danke!

12:42 McD followed with the MD11 in 1990. The MD11 was a FBW/FBC hybrid.
Control wheel inputs in manual flight were transmitted digitally. Feedback was given via the cables.
The elevator inputs are assisted in the neutral position. With no inputs, the elevators are automatically moved within 5° to keep the aircraft attitude stable.
With the autopilot engaged, it's full FBW. The Flight Control Computers (2 pieces with 2 channels each, so four channels in total) control only one of the four actuators (four ailerons, four elevators) dependent on what channel is in control. The other three actuators of the ailerons and elevators are slaves driven by the linkages and cables that connect them all together. Theses cables and linkages also give feedback to the pilots.
The 777 is full fly by wire. There are 16 position transducers on the control wheels/columns/pedals (6 for the control wheel (3 each for CM1 and CM2), 4 for the pedals (2 each for CM1 and CM2) and 6 for the column (3 each for CM1 and CM2)). They provide analog signals for the ACE (Actuator Control Electronics, 4 units) which convert these analog signals to digital. These digital signals are sent to the Primary flight computers (3 units) where they are processed with protection functions, stability augmentation and stuff like that. The processed signals are then sent back to the ACE and to the Autopilot Flight Director Computer. The ACEs convert the digital signals back to analog and send them to the control surfaces. The AFDC send the signals to the backdrive actuators on the control wheel/column/pedals for the protection functions (for example bank angle protection or tail strike protection).
This is in normal manual mode.
In secondary mode, when the PFC lack some information or have internal faults, some functions are not available (for example autopilot, envelope protection, thrust asymmetry compensation), but the PFC still process the digital signals and send them back to the ACE.
In direct mode, when the PFC are not available at all, the ACE send the input signals straight to the control surfaces without processing.
When the autopilot is active, the autopilot commands are sent from the AFDC to the PFC where they are processed and sent further to the ACE where they are converted to analog signals and sent to the control surfaces. The AFDC also send commands to the backdrive actuators on the wheels/columns/pedals for feedback.
When all electronics fail, there is only pitch trim left for pitch control and two spoilers, one on either side, for roll control. These are the only actual mechanical controls left.
The Control wheels/columns/pedals are mechanically linked together, so the L/H side always knows what the R/H side does and vice versa.

Now you've done it. You'll have to do four other videos explaining what are stall, overspeed, spin and overbank...
You _did_ do it on purpose, didn"t you? :p

Real flying is fly-by-“steelwire”😉

I learn so much on this channel! Thanks Joe! Also, I didn’t know until recently that some business jets have the fbw system.

Joe is the only Aviation teacher that I've known of since 2019, I'm also watching this Video While reading the Fundamental of flight book. His channel will always inspire me and increase more of my knowledge.

Phenomenal video really Joe 👌
Informative and simply awesome.

Joe I love your videos. Great content as always mate keep it up. I hope to meet you in the aviation industry soon as a fellow colleague 😊

You got a beautiful Oldtimer, with beautiful instruments - RPM and speedo - from VDO, very nice!

Brilliant, I learned so much!

Just when I need it, Thanks Captain.

Hi Joe thank you for your very good information.

Always enjoy watching your videos!

Another great video, continue to amaze me.

That’s a really good video Captain Joe ! Thanks !

Good explanation. I think I have learnt a lot about planes from you and the other leading channels.

Fantastic video, once again. Thank you.

love the way you explain..

Amazing video, thanks for taking the time to explain it to us 😁

Amazing, simplified explanation b/w fly by wire & Mechanical controls...😍
Waiting for ur next video...

Let's go Captain Joe. Thank you for sharing your knowledge :)

When I watch your videos they inspire me more to become a pilot,I also learn more and that allows me to add to my knowledge of aviation🛫🛫
