Former wire design engineer here: what's crazy is that each and every wire is accounted for, has a unique bundle and wire # ID that is laser printed on the wire. Each bundle is categorized in terms of separation (L critical system, R critical system, Vibration sensitive, EMI emitter, EMI susceptible) etc etc. The wire weight for each wire, each bundle, each little zip tie location is known and calculated to withstand the expected maximum vibrations (non normal conditions). Airplanes are a marvel, in my opinion, the interconnection system, especially for fly-by-wire type aircraft is a marvel in and of itself :)
@@fluffernutter03 As an Electronic Engineer I can completely appreciate the scope of that install the debug the labeling the testing is an incredible amount of work and all must work like its going into combat.
This is very interesting and unique, I have seen some avionics bay walkarounds, but in neither did they explain what are we seeing and none of them was so detailed. I really like this, sometimes because of the noise it's quite hard to understand though, so if you added subtitles, it would be just perfect!
Quite interesting, How do you think about JAL516? I saw some videos from passengers and avionics bay looks fine from outside. They stopped safely after crash. Navigating lights are worked well while their planes are on fire. Some major avionics systems were doing their job i think, Including flight controls, emergency back up power sys, etc.
First impressions I had is that some systems were damaged due to the collision. As for example the PA system seems to be not working anymore for the evacuation. Overall the aircraft did what it needed to do. All passengers and crew were able to get out alive. But after the investigation as after all lessons will be learned and systems / aircraft will evolve to get better.
It’s likely something was damaged in this compartment , as they lost all power ( PA wasn’t working anymore for the evacuation ). All power distribution, avionics and emergency power supply (batteries) are in this area.
Airports are restricted areas and aircraft had security present. If you get past that and have a set for stairs you can enter the bay from the outside. It has no lock. No, pilots do not get the information of what every component does. They just get the short version of how a system works.
Imagine you are a technician working in the avionics bay of the a350, when one of the crew accidentally shut the hatch and the plane proceeds to takeoff 😂
@ there are thee ways to get in and out of the avionics bay, hatch in the cockpit, a door to the fwd cargo bay and a door the the outside. You can open that one (as long aircraft isn’t pressurized and jump out. But you would get warning in the cockpit for both the outside hatch and cargo bay access door. Or just yel. So not getting out unnoticed.
@@standol eh, there might not be a guy specifically for it, and you probably wouldn't go down there in flight, but there most definitely are circuit breakers, although all in the cockpit for obvious reasons. Reset switches, well I don't know specifically about those, but there's no practical controls in the bay flight-wise, everything you could possibly need is wired to a panel above / beside the pilots EDIT: all *flight-relevant* CBs are on the deck, some are down there but I guess they are all not required to be accessible, no emergency in the world would be easier to handle if the F/O had to climb down a hatch to fix it instead of just turning around
Interesting to see but very disappointing messy complexity. So many trivial functions split into separate elaborate boxes with oceans of connections instead of one little integrated unit. And despite all that a brand new airliner doesn't even have synthetic vision. Probably doesn't have a dash cam either or any exterior cameras recorded.
Hi, compared with older generation aircraft, A350 has many intergraded systems. For example the CPIOM’s are loaded with software applications like your cellphone which then can do different kind of functions depending what of the aircraft it is installed (simplified of course). By use of them a lot many less boxes are already installed in the aircraft. And yes it is still missing some newer technologies. In the end if the will ever be installed is depending how useful and accurate it is. I see synthetic vision in there as the will help landing when visibility is low, exterior camera recording not so much.
Wow...must be a million connections in there all of them have to be perfect and able to take a beating vibration wise. Incredible.
Indeed a lot of wiring going through there.

Amazing to see the scale of these systems. I can hear the 400Hz main AC bus at work 😊
wow, very interesting. even pilot don't see this a lot... I flew on A350 many times as regular passenger, beautiful airplane.

Absolutely amazing that we can design such beautiful machines. Great video. Thanks for sharing.
Thanks for watching!
Please do more on the A350, amazing video as always 😊
I ll do my best
Ongeveer net zoveel kabels als achter mijn TV, alleen netter samengebonden ;-) ...... maar serieus; zeer interessant, bedankt!
I love this video so much. Thanks.
Glad you enjoyed it!
That was a great and very interesting insights into the innards of this amazing aircraft.
Wow .
That avionics bay is really cramped . For most of us it will be clustophobic .
Great info . Thanks for showing the behind the panel scenes 👍🏽
This one is not to cramp.
Very nice! Thank you for sharing.
Thanks for watching!
so much interesting ❤ly .thanks fr such tour its a goldmine for me as an electronics enthusiast
thank u dear
This is awesome!! 😱
Please do more like this on the A350 😊
Supper,very interesting!!!!!
Thank you! Cheers!
Captain: What are you doing!? Get out of there! We need to start our decent.🤣
Seriously though, this is so cool.
I was just looking for a nice bottle of wine in the wine cellar air 😉
🤣@@dennisvijverbergbrakesrele6098
Thanks your videos
It seems almost surreal when you see this picture (5:01) and know that it is inside an airplane.
As usual, Like :)

That's a flying data center 😳
Would this be the area that took the most impact in the recent JAL516 incident? Is this behind and below the radome?
It’s likely something was damaged in this compartment , as they lost all power ( PA wasn’t working anymore for the evacuation ). All power distribution, avionics and emergency power supply (batteries) are in this area.
It’s literally a data center on a wings. Is there a schematic of sorts to see what each section, or bundle or wiring actually does at a high level
Can get any person from the outside in to this compartment?
And are the pilots trained where each component below is necessary for?
Airports are restricted areas and aircraft had security present. If you get past that and have a set for stairs you can enter the bay from the outside. It has no lock.
No, pilots do not get the information of what every component does. They just get the short version of how a system works.
is this where the black box is located
The black boxes are located in the tail of the aircraft.
Who would of knew she had so much equipment under her "deck"😳
Ah so are the FDR"s also located somewhere here?
No FDR is in the back of the aircraft.
Is it pressurized down there
@@lolloll4441 yes it is all within the pressurized area
@@dennisvijverbergbrakesrele6098 wow it’s like a whole apartment down there
Awesome video. Although with a very misleading title of WALKAROUND...This was clearly a CRAWLAROUND video!🤪
thank you movie

@@inniyan-ef4nh only in movies, I ll have to get out like Arnold in Commado
@dennisvijverbergbrakesrele6098 😂 could that actually happen, if it did, what would the technician do?

@dennisvijverbergbrakesrele6098 oh ty!
Thanks are there IT technician on flights to reset switch and circuit breaker in case of emergency?
No

Do you have schematics diagram of the A350 E/E Bay (Avionic Bay)?
Thank you Dennis, got to see a lot. Appreciate it.
In which part of A350 is this located?
You can find this area under the flightdeck.
@@dennisvijverbergbrakesrele6098 I see. Thank you.
Basically a computer with wings.
Indeed but not just one computer 😬
But can it mine bitcoin?
With the right software it probably could 😜
a lot going on in the birds brain
No comparisson with the mess of an avionics compartment in a Dreamliner.
Avionics seem much better and clean than 330😂 .
Thank God they don't run on windows systems haha
You would be surprised. Here and there a windows operating system pops up. But not in the A350
Ya l tell geeee
