Dear friends and followers, welcome back to my channel!
.... So the best-known feature of the Airbus fly-by-wire system is the sidestick. I did a whole video on the sidestick, which you might wanna checkout right here. So by moving the sidestick, you actually move mechanical levers and dampers which sit below the sidestick and this movement gets converted into a digital signal. Okay, let's say we were to make a left turn. Our left turn digital signal then runs by wire to a set of seven Flight control computers. The first one is ELAC 1. Which stands for Elevator and Aileron Computer. ELAC 2 acts as a backup in case ELAC 1 fails. So the ELAC 1 checks the received digital signal, before sending it off to the flight control surface. What I mean by "checking the signal" you'll see in a minute. So from ELAC our left turn digital signal then yet again runs through a wire/electric cable to one of the hydraulic actuators on the left-hand aileron and on the right-hand aileron, where our digital signal is then converted into a mechanical force moving the left-hand aileron upwards and the right-hand aileron downwards. Does that make sense so far?
I hope you enjoy the video and it’s been helpful to you!
Thank you very much for your time!
Wishing you all the best!
Your "Captain" Joe

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

one day he will say "This is not a car, but my Concord"
Just an ordinary car...
@@bradlemmond You're an ordinary car.
@Lorenzo Ramon Fuck off dickhead.

Legends say that the interview with the Concorde pilot must be released at some point.
Pilot: 'disconnect autopilot, I want to fly manually'
Airbus: 'I cant do that Dave'
Pilot: 'well, my name is not Dave'.
Airbus: 'Ah my mistake Sir, disengaging autopilot in 3-2-1'.

11 years ago today, the "Miracle of the Hudson" was successfully pulled off ❤️
11 years ago today, I was 11 years younger.
I think it was 12 years ago.
Actually it was tomorrow
Riding the envelope 👍
@@moviestudios4681 12 years ago , I was 12 years younger
That feeling when I see it’s been posted 32 seconds ago
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
All of the ones previous to Airbus were analogue, though. It was also on the Avro Vulcan and A-5 Vigilante.
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)
Already in the making
@@flywithcaptainjoe can you please explain how the radios work and how to operate them? please
@@flywithcaptainjoe yes king!!!
@@flywithcaptainjoe Eagerly looking forwarding for it. Many Thanks!
Don't forget the dreaded "mechanical backup" 😂
Great video as always! Would you consider making one about how pilots navigate across oceans, particularly before GPS?
Nice idea for a video!
@@flywithcaptainjoe please could you do one about navigating overall. As in GPS waypoints, SID’s/STAR’s etc and maybe different types of approaches
Probably using loron c
Before GPS it was LORAN, OMEGA, and Inertial Navigation which was from about the 1960s.
Before that, it was dead reckoning using a drift sight and flight computer like an E6B and making sun/star shots with a solar compass or a sextant. Errors were often significant and cumulative.. but usually good enough with the forecast upper winds from all of the weather ships to enable you to home in on a VOR or NDB which had ranges of a couple hundred miles.
Compass and going dead straight then adjust
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!!
Hey, what's your progress for today?
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!
I’ve reached my goal😉
Thank you, Joe! Your videos as usual are clear to understand! Greetings from Ukraine!
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.
Now this is the topic I’ve been waiting for! Thanks for the great content Joe!
How would you know? You commented 2 minutes after the video went live.
You know what a thumbnail is, right? And this is obviously not the first time I watch his channel.
Great aviation vid Joe. Keep it up! Also thanks for doing my suggestion for a vid! 😁
That is pure gold! Thanks for all the knowledge!
Does Captain Joe miss Airbus already???
Yep
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.
This is something I’ve always want to know
I love this pilot of pilots! He brings the depths of aviation right to your eyes. 💛🙏🏼
Awesome video love the March keep up the great work
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
Hey! Thanks for explaining that.. I always wondered what that meant 😃
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 :)
Thank you so much captain joe for your videos is very great.
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.
I wonder what becomes of Joe's face everytime he sees an A320 while in the cockpit of a 747.
Cheers, Joe
"I use to fly that lil mosquitoe" 😚😄
Hahaha
“How do you do, fellow kids?”
Advantages and disadvantages are quite right and objective. I really like your videos. Perfect.
Very nice video, Joey! Glad you inspire young people for aviation! 👌🤗
Fantastic video loads of info we are always learning..im wired
Another great vid joe!
@Just Jeb True
You are first! good vid tho i agree
@Just Jeb But it’s a captain joe vid. It’s gonna be good for sure
@@yulaviation3868 Yeah Thats For Sure
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.
Always enjoy watching your videos!
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
😂😂😂
Well technically they can know what you watch, it's how you get personalized recommendations
You are my most favourite RUclipsr🤩🤩🤩
the explenation.. so clear as water!! keep up the good work!! 👍😊
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!
Fly by wire is truly interesting
Yeah
"Der Mann hat Geschmack" Nice little Red Machine in the beginning and great informative video as always!
Thanks buddy
@@flywithcaptainjoe You're welcome! Correct me if i'm wrong because i'm not entirely sure but isn't that a 930 2.7L ? :)
Love your videos Joe👍
Not a pilot but always curious about this incredible machines work, thanks for always giving clear information!
What we all have been waiting for without even knowing it
Hi bro!
@@EmilSvitek - Hey another Lime
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
we are always enjoying with your clarification . Many thanks capt. Joe
I had a general understanding about the system but yoour explanatiion went into way more detail (compensation and stuff), thank you!
Question for joe: Do you think the airbus cockpit is easier to fly than the Boeing (in terms of space and comfort)?
Yes I do
@@flywithcaptainjoe Is it because you flew Airbus before Boeing? (Or Maybe you also flew Boeing before the A320?)
@@matthsini As far as I know, the 747 was his first Boeing, after the A320. But regarding the comfort in the cockpit, you can check the video where he and Dutch Pilot Girl compare the A320 and 737, where you have a more direct comparison with arguments from pilots from both sides.
The future is here😁
Are you a fake Elon Musk ? Your video doesn't sound like the real one.
Nice Porsche!!! And really great video, thanks. Greetings
That’s a really good video Captain Joe ! Thanks !
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'd love to know thid
I'm not sure but I feel like you wanted to show off with your Car ;)
Greetings from Hamburg!
If I wanted too, I would have shown the full car like other pilots do.
@@flywithcaptainjoe haha true,
and you would need a way more clickbaity thumbnail with a way cooler car than the one in the video.
Very well explained. Congratulations and have a great day.
Fabulous video! Superb animation and delivery ! 😃👍 thank you!
Nice Porsche !
No please captain don't put a video online when I've an importante school teste to revise for tomorrow 😂
Now I want a video on your car!
So spot on explanations. Leaves me out of questions. Everything g so clear, I’m just an aviation geek.
Fantastic video, once again. Thank you.
I didn’t know I was this early
I like how he says "little cessna"
I would love to see a big cessna
Cessna cititation then
@@firmaneffendi2801 no something bigger. A cessna c380. A cessna version of the a380
@@Smartlion1 chestnut then XD
Just when I need it, Thanks Captain.
No one explains stuff better than you Captain Joe. I appreciate you
Also here's a suggestion: MFS2020 747-8 landing challenge.
I rather do it in the real plane😉
@@flywithcaptainjoe Oh ok. That would be an amazing video! You could do a Boeing 747 tour. If you haven't already though.
74 Gear tried it and found it wildly inaccurate.
@@NiHaoMike64 Yeah because his 747 was bouncing at 120 knots. My suggestion wasn't good.
@@flywithcaptainjoe Can you help my new Aviation Channel? It only has 13 subs, and if you want to go to it, search up cessna 172 descent and landing. Just wondering. You don't have to.
1:54 - Should that be FWB or FBW for Fly By Wire ?
FWB is absolutely not Fly-By-Wire.....
@@joegreenwood6551 It seems that captain Joe had a wonderful day lol.
Joe Greenwood It is it should be FBW Fly By Wires
Fly-Wire-By doesn't seem right :D
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!!
Thanks for the video.
1:52 the acronym had a typo lol
FBW
Captain Joe and Sam Chui collab maybe?
Maybe that's already a thing IDK
Chui is overrated
@@Hans5958 Chui has social videos more than technical and he is likable. You can tell from his hosts whenever he is filming.
Very informative like every video
Brilliant, I learned so much!
1:54
Isn't is supposed to be "FBW"?
It's the Friends With Benefits system
I think I’ve never clicked on a video this fast :D
Good looking Porsche. Glad to be seeing your videos again
You got a beautiful Oldtimer, with beautiful instruments - RPM and speedo - from VDO, very nice!
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
That’s actually why the Boeing 737 Max failed
I'd say it's potentially much more reliable than the pulleys. The old system has also wires, but so many more things that can get stuck :)
I was literally thinking about u 30mins ago
Thank you for the video joe
Thanks very much Prof. Joe
I know this is an immature joke but I very young so I was like, Wut da 5:25
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
A stall is when the stream of air flowing over the wings “detaches” from the wing and turns from laminar flow to turbulent flow. The rest are pretty self explanatory.
@@gabrielsimon7944 sorry but no, this does not explain anything at all. I know about Navier-Stokes equations, which ultimately describe all of these phenomena, but knowing about the theory and how it translates into the real world is quite different...
@@francisgaliegue6645 I don't understand what you are expecting. Stall as explained by many pilots (and Gabriel Simon) is clear. What happens in the real world? The airplane simply falls down since there is no more lift. No need of equations to understand that. Spin is an asymmetrical stall: one wing stalls before the other and the aircraft goes into a spin (there are many videos dealing with this physical phenomenon). Overspeed and overbank are self meaning, aren't they?
love the way you explain..
Beautiful video!! Thank you!!
Real flying is fly-by-“steelwire”😉
Excelente video Joe!! Really good
Phenomenal video really Joe 👌
Informative and simply awesome.
You helped me a lot with a flight tech school project about ATA 27 group (FCS). Thanks a million.
Wow!
Thanks so much!
For this valuable information!!
As usual useful video , and comment to your viewer , thanks Mr. Joe
Awesome as all always
Glad your finally uploading new videos
I appreciate your very clear explanation and also the work of all engineers who have developed the system.
Another great video, continue to amaze me.
Very informative as always.
Your vidoes are why i am so into aviation, and i am loving it
Means a lot thanks!
Hi Joe thank you for your very good information.
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.
depending on the aircraft, there sometimes is limited mechanical backup most commonly for the rudder and the horizontal stabilizer. that said, if the aircraft is so damaged that all redundant electrical and digital connections fail (that would mean no engine power, no apu, no battery power, no ram air turbine...or a fire in the avionics etc.) it will most probably crash anyway regardless of the control type.
Great explanation.
Great video, thanks.
