Dear friends and followers, welcome back to my channel!
In today's video we'll be focusing on the famous ACARS system, which allows pilots to send requests to a service provider (SITA or ARINC) via VHF or SATCOM. The datalink service provider will process their request and send and uplink back to the plane.
But see more in the video!
Thank you very much for your time! I hope you enjoy this video!
Wishing you all the best!
Your "Captain" Joe
Big thank you to all other youtubers who provided me with the video material to create this video. Your content is highly appreciated. Please follow their channels:

😂😂😂
from where does the captain joe have these recordings please, don't you know? :D
@@Godletrich Look up Kennedy Steve here
8:32 I guess it's a parking position where pushback is not required, engines are started earlier than the brakes being released
You smart
Same
I agree
Correct!!
i was going to answer but i am late . any ways your answer is correct .
4:50 "captain I can't see the runway"
"Ah the satellite dish has fallen on the windscreen again 😶"
😂😂😂
4:45 Ah, so that's what that large dish on top of airplanes are for!
Immarsat provides inflight wifi too as a bonus AirNZ uses it
I'm no expert, but that doesn't look very aerodynamic
@@LuizDahoraavida It isn’t. The winglets on an aircraft give about a 5% reduction in fuel burn. The antenna on the top of the fuselage eats that up.
@@oscarb9139 r/woosh
@@simpilotadamt1012 Obviously, there is something I missed if it was a whoosh.
5:22 well I guess that's just another reason why airplanes are better than girlfriends 🤔😂😜
Definitely not faster than a WhatsApp message from an angry girlfriend
We just studied this today in ground school. Good timing!
Dang, Never would have crossed my mind to know that aircraft talked to each other.
This man helped me pass exams I am now done training
congratulations
@@yuichi1925 Thanks man!
Congrats! blue skies be with you.
The "Minimum Equipment List" is an important topic for me as an Aircraft Mechanic and for you as a Pilot and would be a great upcoming video! :-)
Good idea!!!
@@flywithcaptainjoe Don't all MELs of the same category have the same number of checklist items?
Both hands up, seeing explanation of MEL would be nice 🙂
@@TAILSORANGEs Your question doesn’t make sense. Can you elaborate?
8:40
3 minutes from brakes off to wheels off the ground?...
No push back required.
How do you know the lack of pushback? Is it because breaks release after enginr start?
Yes with a pushback brakes are released before engine start up
I also assume that with a push back you release breaks first, then push back, then start engines
@@phillips2400 Wouldn't you have to reapply the brakes after getting the pushback so the aircraft doesn't keep rolling backwards?
@@NiHaoMike64 good question. Since the aircraft is connected to the pushback vehicle it’s the vehicle that stops the backward movement. I don’t think the aircraft would start rolling on its own after the disconnection. But that’s just my guess. Maybe somebody knows it better?
Me from Riyadh: Oh finally, some knows a place except Dubai in the middle East
I'm guessing this flight had no pushback, since the engines were started before the brakes were first released? It's frustrating though that these aren't in chronological order. Is there any reason for that?
Just yesterday I was looking through material to learn more about ACARS and today Captain drops a vid about it) what a timing)
xd same
Pushback was not required because you released brakes after engines started. Am I right?
No pushback required. Time from brakes release to engines on is negative.
Ans: the pushback was not required I guess
Can someone tell me if I am correct
@@RADISH_APPROVED I thik that it is correct, because he liked your comment, and because he didn't like the other comments that are wrong.
So yeah, I think it's correct😂
I think your answer is right because according to the time records on the display at around 8:42 in the video, we can see that the brakes are released after all engines are started. This would implies that no push back was not required.
I think if there was a push back then the brakes would be released first and then engines started.
@@thomasclark604 my theory as well
8:40 last engine started at 0610, brake released at 0613, airborne at 0616. No pushback required.
All engines were running before parking Brake was released. So no push back was necessery.
Actually early! as always very interesting vid Joe, keep them up!
I'm guessing no pushback was required, because it was only 3 minutes from releasing brakes to take-off...much less time than it takes to attach/push/disconnect the tractor? Also - the engines were started _before_ the brakes were released, whereas they're usually started during the pushback procedure (ie. brakes released first to enable the push; then engine start)
Capt joe is full box of knowledge
Hats off👏👏
Answer: no pushback as ENG run before brake release
What I learned from this video....747's have printers in the cockpit.
They have floppy readers too. There's probably a secret key combination that brings up an Excel 97 simulator.
And so do: 737’s, 727’s, 757’s, 767’s, 777’s, 787’s, A350’s..........
Sadly, ACARS never works. And I have to walk paper copies to the plane 😭
I know what you mean 😂
ACARS works all the time, question you have to ask is - is your airborne equipment working and configured properly, do you have a service agreement with ARINC/SITA. Have you paid your bills, are you at a tiny airport?
First video of 2021 🤗
Capt. Joe, your a first class ticket and I'll always fly with you thanks for sharing your story with us that watch your channel. Outstanding job sir.
9:00 I guess the "digital" in FADEC is silent :3
Joe, thanks for an awesome video once more. We appreciate all the work you put into it. I would like to see a CAT II & III ILS apps explanation video. Thanks
Hey, he’s back! I hope you had a great Christmas and a happy New Year!
To answer the question at 8:30 , I think the aircraft was at a self repositioning stand. (No pushback required)
Hi Joe, it would be very interesting if you make more videos about radio systems on board.
Also, I am an amateur radio operator or ham (Amateurfunker) and I had once the opportunity to talk with a pilot (he Also was a Ham) on board a Boeing 737 using their HF 14MHz SSB radio.
It would be very interesting if you could give some insides on that topic or if it is in fact possible to transmit on the amateur radio frequency.
Captain Joe. Can you talk about CRM?
What are the fixed and variable costs of this system? I guess the airline must have some contract with the system provider and make some monthly payments. I think it is not cheap as even the disappeared Malaysia Airlines MH370 did have only some basic version of ACARS, so it would not help much even if it had not been turned off. Is it available and affordable for a privately owned single pilot twin engine aircraft like Beechcraft Baron or King Air? I guess the SATCOM will make it more expensive, so is there a possibility to buy just VHF or HF version?
What I don't understand is with satellite and cellular usages so common, why is civil aviation still rely on Flight Data Recorders? All Flight/Voice Data should be transmitted to company and/or FAA headquarters instantaneously and continuously, with onboard data recorders as backup. In case of accidents or incidents, data can be retrieved and analyzed immediately without having to search for the black boxes. It may also aid in locating the accident/wreckage site quicker and more accurately. Any thoughts?
Puch back wasn’t required cuss all 4 engines were started before brake release & capt. Is PDC by ACARS only popular in US or around the world especially in Asian countries?
How are you buddy I'm not sure if you are into video games but try out new flight simulator 2020 preferably in VR and tell us what do you think.
Amazing videos, keep it up.
You were not pushed back!
The brakes were released after the engines ran. If you were pushed back, you would release the brakes and then fire up the engines.
Also, 3 minutes after the release of breaks the aircraft took off at 06:16! How can you push back and take off that fast?! 😲🤣
Hi Captain, thanks for the informative video. I'm in the middle of the ATPL course in Ireland and we have covered instruments, so your very clear and informative explanation really helps. I have watched other videos you posted too and I have learned a lot so I'd like to say thank you so much for putting the time in to create such great content. It is very much appreciated. And one more thing, the 1 minute debriefs are great too. Some classic reactions. All the best, Anthony
RIP #SJ182
I am trying to understand how BOTH Altitude (blue) and Speed (Yellow) went down together for 10 seconds! Then the plane entered a #Stall (like a rock)!
- I think something structurally went really wrong!
- That induced a sudden huge drag.
- No stall recovery attempt?
- The #SJ182 (Boeing 737-524) glide ratio is 17:1!!!
- There is a huge and suddenly induced drag! I am starting to think Reverse Thrust activated with full climbing thrust engine power?
- But something else failed! 10 seconds, and no pilot correction although their hands on it
- Rudder seems to be jammed to one side, probably because of the pilot trying to force a Yaw correction?
Im going to say you were in a no push-back gate location because you were brakes released at 0613 and wheels up by 0616
too short of a time period for a pushback plus takeoff.
There wasn't pushback: If engines are turned on while pushback, why brakes are realased later than engine start?
Nope, this aircraft was started on it's stand at 0608 to 0610 then the parking brake was released at 0613 and wheels off at 06:16.
If you were pushed back from a gate with a tug it would have been Doors Closed, Brake Off, and THEN engines start.
How much is one message sending via acars ?
Flatrate as far I know
Hey Joe I want to become a pilot and I don’t want to stay in a regional airplane for a long time for do you know what base in your opinion has the fastest upgrade time?
Hi my brother has been watching ur channle for years now and he really wants to become a pilot. Do u have any tips for him?
Well youtube adds get more and more aggresive. Sorry CJ, loving your content, but it's inposible to focus on it, when you get interupoted every 2 minutes for further two to five minutes.
All the best
Sorry buddy, not in my control 😔
@@flywithcaptainjoe Yes, I've figured it, because a lot of good channels are showing this issue for a few of months now. To some extent it is possible to ignore and deal with it. But the tendency is approaching and overreaching all the limits of tolerance. Some publisher is taking evasive measures already and starting an own web service. But I do realize, that for you, as for an active flying pilot, it is unacceptable simple for reasons of time management. I don't have the luck to even finance or manage my passion for flying such economical kind of flying as weight shift aircraft is. That why I had no intention to criticize you, but only to inform you about the current state as a fan of your content. I have high respect for your work, and I'm still thankful and appreciating it. Have a nice 2021!
Long time no see 🙈
Hi Joe watching your video from Riyadh Saudi Arabia happy to see it in your video
Please could you explain about Fly-by-wire please. I really enjoy your videos keep up the good work 😆😁
Wait for 7 days😉
@@flywithcaptainjoe 🤩
Why isn’t there continuous satellite data telemetry for all commercial flights so we don’t have to go fishing for Flight Data Recorders underwater after the fact?
Brakes released after starting the engines. SO DEFINITELY NO PUSHBACK REQUIRED.
Now could you please click that heart button for me, sir😆😆😆
Edit: maybe a tutorial on flight planning for next video would be really great :)
Merry Christmas and Happy New Year. Glad you're back.
How much ACARS messages costs to airlines? Satellites ang ground stations im sure are not free. Or this is a big secret?
Very good video!!!!👌👌👍👍
I also want to become a pilot someday. I already learn a lot about aviation through your videos
I've been waiting for a new video for a long time. I love Joes videos
Love your videos
And expecting a fan visit in riyadh Saudia Arabia
Can you show the auto land procedure?
Happy to see you again. Very informative and very clear as usual. May I ask you some short questions?
Regarding MH370, indeed ACARS has been shut down but it restarted later on, emitting the so-called "pings" to an Inmarsat satellite. And if we know now where MH370 approximately crashed, in the south of the Indian Ocean, it is precisely because the ACARS was not completely dead. That's how they got the famous seven arcs giving a probable location of the crash. Problem: no other communication mean seemed to be working. It's all about ACARS in this mystery and it's a pretty disturbing thing. Moreover some specialists said at the time that it was impossible for the crew to shut it down in flight. Hence my questions:
1. Is it started manually or automatically in the starting procedure of the aircraft?
2. Even if it is automatic, would it be possible or not to shut it down manually in flight (I mean without descending to the lower floor in the avionic compartment)? If yes this means that it might have been deliberately shut down by the crew. Why? That's another question ... If not, why did it stop?
3. If it is only automatic: let's imagine a total electrical failure leading to the shut down of everything (provided that it makes sense) followed later on by a restoration (partial or complete). Could this restoration trigger the automatic restart of the ACARS (and only the ACARS)? Why in this case no aircraft data (especially A/C position) are transmitted anymore from the ACARS except the famous "pings" telling to the satellite "yes I am here" and only that?
Obviously I don't ask you the solution about this mysterious case, just some additional information about ACARS, if possible and not classified of course. Thank you in advance. Best regards
Hi Joe, about a year ago you promised to tell how you managed to put those model planes so nicely on the wall. Can you tell the secret please ;)
No😉People will just copy it then😉
Ig it was a gate position where no push back was required..
Finally!!!!! Ill downlink this to my brain !!
I worked in operations (AOC) for an airline & I'm very familiar with the usefulness of ACARS. I've a folder of messages I've kept from tech crew who sent me jokes as part of their messages. It's a great collection. If no jokes, or any humour, weren't included in the ACARS, then I knew tech crew were having a full on hands on day & no time for a bit of joviality.
Sup. Love your videos
i first learned about ACARS was from the missing MH370
What is your story Captain Joe? When and why did you start Aviaton?
He entered flight school 2007. Flew skydivers to 14000ft 32 times a day on a Pilatus PC6. idk how long. Then flew the Beech King air 200 for idk how long. Then moved to the A320 family in Air Berlin for 8 years. Air Berlin went bankrupt in 2017 and he transitioned to the 747-400 and -8 flying for Cargolux. Still works there today.
Could u make a video of a out side walk around or outside check with the 747 plz
I know u have already made one but I want you to make one with the 747
8:40, I think there was no pushback required, because the first engine (nr 4)
was started 5 minutes before the brakes were released
No push back required. I think the parking brake is engaged when the engines are starting. If there was pushback required the parking brake would have to be released before engine start as the aircraft wouldn't move if the brakes were engaged. In that case, the brakes would be released, armed, then released. However the FMC here only shows brake released after all engines have been started, so I think no push back was required in this pic.
There was no pushback at your gate, the engines started prior to the brakes being released, you would release brakes before engine start if you got a push
nice in depth video!
Interesting video!HAve a question :can be pilots ever be replaced by AI before 2055
No
Of course, UAV is reality, air taxi in 5 years.
Your plane wasn’t pushed back.
No push back (I guess) because you started all the ENG before releasing brakes only once… am I right?
Joe can i become a pilot if I am bad at maths like for example I barely pass in maths
I think. No push back required.
Awesome video Captain...Lots of love from India ❤️❤️❤️❤️...I think in MH370 case the pilots switched off the ACARS so that they cannot be found 😭😭...Can they be switched off manually
I thin no pushback, because when you would have been pushed back the parking brake would have been released twice, one time before pushing and one time before taxiing.
In addition all engines were avail before the first release.
Cool! Did you record part of the video in Vienna? I saw LOWW written in the airport code field, before you keyed in the new airport code...! Very interesting video, by the way. Finally something that nobody has talked about so far...!
What 3D Model of the cockpit is that?
MSFS2020
Just heard a 737 500 went down in Jakarta sad news
no pushback was required because there is no pushback printed on ACARS sistem
I've pre-ordered captain joes airplane model, and it didn't arrive yet... 😢
It may be stuck in a holding pattern waiting for ATC clearance to land at your doorstep. :D
Hey David! Sorry to hear that! It’s probably stuck due to corona pandemic 😕
@@flywithcaptainjoe Yeah, I also think so, but I live near to Stuttgart so it's kinda weird😂
The aircraft is pushed back
Please do the next video on talking to ATC
The plane has been pushed out of the gate.....
Captain Joe, have you ever seen 🛸 👽?
please cover the navigation plotting topic
Do you spend more time in hotel rooms or at home
Captain please cover some aircraft maintenance engineering topics. Much needed
You'rea great instructor. Thanks Captain Joe for sharing knowledge about Aviation. Please make a video on CTOT, EOBT.
I think your aircraft was not park to a gate so that is why Pushback time not showed. May be
I think Flight crew OFMH 370 turned off Transponder that is why the expensive SAR failed
hes back!!!
When is the glider video with Luca Bertossio coming? Looking forward 😍
Video is finished with editing and now in the waiting list for release😌
@@flywithcaptainjoe Amazing, can't wait!
Thank you captain Joe. Please make a video hydraulics and pneumatic systems and how are they related to fly by wire methodology.
Fun fact: ACARS isn't encrypted and can be easily received and decoded at home using a cheap RTL-SDR usb dongle and a bit of dedicated software.
It helps if you're near an airport or under a trafficked route but anyone can try and setup a receiving station to see what's above
Great explainer Joe. How does the system avoid congestion on VHF if so many messages are being transmitted? Does an aircraft have an exclusive frequency, and are the messages enrypted or can anyone "hear" them?
Just a rtl-sdr usb dongle... and good antenna not to be deaf... then you can listen to every vhf transmission: acars, ads-b, atc radio, even decode weather satellite images...
My guess for the challenge at 8:43 is that there was no pushback. I believe this because I think it said engines 3 and 4 were started at 06:08 and engines 1 and 2 were started at 06:10. However the brakes were not released until 06:13 meaning all 4 engines were running during the “pushback”. Usually the engines are started during or after pushback but not before (I think, I’m just some plane spotter lol). But I think there was no pushback. Am I right? It would be great to have a response or a pin from my favourite pilot, “captain” joe ;)
right, he has to change his name to FO joe!
Looks like the aircraft was pushed back. Picture was taken in air
Sensor status gives the answer
You are also very good teacher sir
