Dear friends and followers, welcome back to my channel, clarifying another great question. Why is there a spiral or swirl in a jet engine?
The primary reason for painting designs on engine spinners is for the safety of ground personnel. Working near a running jet engine is extremely dangerous. For example, a Boeing 737 engine, running at idle power, has a hazard zone of 9 feet to the front and sides of the engine. This means that, even at idle thrust, a human that walks within the hazard area or any loose objects, risk being sucked up into the engine. When the engine is above idle thrust, the hazard zone increases to 14 feet or more. Not to speak of the even larger hazard zones of a B777 for example. Therefore it´s absolutely critical that ground personnel can identify a running engine and stay away from it.
Even though jet engines are incredibly loud, a running engine may not be obvious to ground personnel. Airport aprons often have several aeroplanes in close proximity with engines screaming next to each other. Therefore ground personnel have to wear hearing protection to suppress the deafening noise. Making matters worse, it can be hard to see that an engine is running, especially during night-time operation, as the black and grey fan blades become translucent when they´re spinning.
Therefore spinning spirals make it a lot easier to identify a running engine. Besides that, ground personnel can check if the aeroplanes´ red anti-collision light is still flashing. This indicates that pilots have received their start-up clearance and will start the engines very soon. On arrival at the gate, the light is turned off by the pilots after the engines are shut off and „spiral“ down, after which it is safe to approach the engines from either side.
For the same safety reason, the tips of propeller blades on propeller-driven aeroplanes like the Dash Q400 are painted in bright colours, to be more visible to the human eye. You won´t believe how many incidents have happened in the past involving jet engines and ground personnel.
Do they scare away birds? That and more information in the video!
Thanks for watching, all the best your "Captain" Joe

Getting sucked up an airplane engine is probably one of the worsts way to die
You are literally blended to death
but its very quick.......takes just a milisecond and the pain is over!
I think falling into smelted iron is worse. You literally melted to death.
@@oldi184 idk, it would burn your nerves so you wouldn't feel it, just bake from the inside out
falling from a sky scraper where you're conscious and aware the whole way down.
That one guy got sucked up into one and survived, somehow.
TLDR: it’s for safety to show the engine is spinning or off
Thank you!
Please pardon my ignorance, but what does TDLR mean?
Risky Nights in this case it’s more like “TL;DW”
David Cruickshank uhm how is this not obvious?
Scootes hey some people may have no knowledge of aircraft but enjoy its fun facts or something - we were all like this once
Ball? Swril? Why not just have the whole Ubisoft logo on the turbines!
Concurrent Flame omg you deserve Hundreds likes
Maybe cause it might randomly crash?
That would scare off more than just birds
Because the engines would shut down randomly for no reason
Because it would scare birds, but attract gamers....

Will it blend? I’m sorry. I’ll let myself out
F**k them they can kill 100s of people when on air
@David Daivdson hmm 🤔
According to Captain Sully’s landing in the Hudson, no, the spirals don’t scare birds.
It scares the birds alright.... They just get incinerated right after.
"Lake Hudson?" You mean the Hudson River? Lol
@@Avus95 LOL HE EDITED IT
Nothing said they COMPLETELY prevented bird strikes, and they are more for protecting people.
They were hit by geese and geese don't hide in holes/caves. And as he said, it's about likelihood.
Tangerine dream - love in a real train on the background.
Love it!
How about glow-in-the-dark spinners, don't know about complications but would sure look cool in the night ;)
I was thinking similar for propellers, have LEDs mounted at the tips, probably powered in a similar manner to de-ice systems. Would make it way more visible, day or night, than just paint stripes. Would look really cool too.
I was thinking the same thing put some glow paint them look real good
@@quillmaurer6563 That would cause issues as the Aeroplane already uses navigation lights to indicate to other Aeroplanes the direction the plane is facing. Having additional lights would cause confusion.
@@ub3rfr3nzy94 Potentially but a lot of planes also have other lights on them other than the required position lights for various purposes (shining on the wing to check for ice, on the tail to light up the airline's logo, even just more lights to make them more visible). I'm not aware of any restrictions on extra lights - maybe there would be rules like not having green on the left or red on the right (that would be particularly confusing), but otherwise I think it's pretty much whatever you want, and more lights are probably better for visibility. I could also imagine the prop lights I suggested only being on while on the ground, as their primary purpose would be to make the prop more visible to ground crews, they wouldn't really serve any purpose in flight anyway.
@@quillmaurer6563 or just make the fan blades white :P
It's our favourite pilot "captain" Joe!
Airline "captain" wearing 3 bars that's a first~
Ok
I don't get it, can you explain it
FAVE-OUR-IT
Deathinity he's a first officer not a captain
Köszönöm szépen a fordítást! Captain Joe warm thanks for the video!
This 7 minutes video answers my 5 years question. Thank you Captain!
Brilliant Video Joe, great content for me to watch as an student who is about to start a Pilot Studies Course to become a Commercial Pilot
I'm happy to hear that!
Captain Joe Such An Inspiration! Going to be applying to study Pilot Studies at L3/ CTC Southampton which is 5 minutes away from me, or Pilot Studies at Bath University or Brunel London.
Some airports like KPDX, Portland, OR also use trained birds of prey like falcons to scare away other birds!
Here holland to
When a board is doing much more productive and important things than me
Not cool.
A Good pilot knows everything about his equipment. And always adapts new mechanical dexterity, safety techniques, and ability to foresee any issues to avoid.
Your videos are extremely interesting. They help me understand concepts I would normally overlook.
At 1:51 that engine is taking a piss 🤔
lmao no its the water the engine is fast enough to make a small tornado
Lol it looks like you are right.
@@axis4741 r/whoosh
i dont get it

Well yes, but actually no.
Thank u for this video sir.
Another winner. Thanks Joe. I really enjoy your stuff.
Dude. Thank you so much! I have always wanted to know this!
Cool, calm, collected.
Nice, appreciated, thankful!
This,is,pretty,weird,I'm,out.
It’s great that you are back
You know your stuff, mentioning the spinner on the Me-109G. Your series is the best on commercial aviation on youtube
Fantastic information for travel enthusiasts.
To hypnotize the birds. Just ask Captain Sully.
@@Pan_exe_ read this
@@ILikeEatingChicken read what..
@@Pan_exe_ good thing your still alive
@@ILikeEatingChicken yeh hypnotizedfox aint no more
I think it's interesting how Rolls-Royce’s Engines have yellow spirals instead of white spirals which most engines have.
They got white 2.
And the turn in the other direction!
burgy boy23 I know, but most of them are yellow.
Captain Joe True, I forgot to mention that. That's the difference between Britain and US 😂
Captain Joe The correct direction :-):-)
Capt Joe, before you, nobody has explained the airplane. I like you mix humour and knowledge. Thanks for making such a complicated thing simple.
I’m not any sort of air employee but I’m a subscriber now. Great content 👍🏼
He's such a good teacher😍
Who else loves the new grey background in his videos?
I do ;)
Captain Joe same! Btw Captain Joe, can you please make a video about how you became a pilot? You said in your video “10 Reasons To Become a Pilot” that you would make a video about it
Thank you, that was so helpful, I often wondered if the spiral has a purpose other than looking cool, as part of the design. It have to say, it has been just the last few years that I have. Noticed then being used on commercial aircraft. I am very observant. And don't recall seeing the spiral 3 years ago. I vacation twice per year or even 3 times. Thanks again this was interesting.
I'm always learning... Good stuff
absolutely fantastic video again, thank you for taking the time and putting the effort in to make this for your viewers. i myself really appreciate it. very informative and educational video. thank you and kind regards kieren
My pleasure and thanks for the appreciation!
hey joe sir!
love you and your vids!
i wish i become a pilot like you one day :)
Thanks Buddy! I hope you do!
Your plane intro is like the most creative I’ve seen
I like the fact that it' simple yet effective for solving the issue with gnd personnel.
Always wondering why they painted the symbol..and today I know the answer,thank you^^
Wow man thanks for listening to my request... It was my biggest question ever... Thanks Captain ...
My pleasure!
"...and the birds aren't happy about it either."
Trocken. xD
Thanks joe I love your videos can u make a video of which way does the Engine Spin and why
Great info! Thanks!

Great Video, i like it to get informed about themes i never thought about before :D
also, thank you for not censoring the 109's sound

Captain Joe,
I really enjoy your channel. You do a great job.
Answer: to alert people on ground that the engine is ON so that they dont turn into a human smoothie.
A person is cheap not a turbine
Make it a straight line though
Jet engines are super loud you can hear them like 50k feet in the air
@@luisescobedoom2053 not that simple friend
@@luisescobedoom2053 lol you need to have a military jet fighter come at you at 100ft and say that!
Congratulations on your new type rating, sir! I think flying the B747 is a dream shared by most, if not all airline pilots...they could not have chosen better! Hopefully we will get to see more 747 centric videos going forward :)
I always loved seeing the spiral on the prop cone of the BF/ME 109.
Check out our channel to learn about real jet engine systems.
Always learning - check. Thanks, Capt. Joe.
Hello Captain Joe. I'm working at airport and notice that some of engines have rubber cone in center. I'm keep asking captains what is a purpose of those rubbers, but no one can explain me. May be you know? Thank you for great content!
Marius Tiskevicius the rubber cone is to allow Ice to shed.
@@judddaigneau2414 Yes, agree, Thats what they told me at my Rolls-Royce training
This is what happens when the internet works correctly. Someone asks a question and gets an accurate/expert answer.
I formerly worked for an Airport. 33 1/2 years - just retired.. Years back I saw the aftermath of a ground crew person walking into a propeller. That's all that needs to be said. I choose to not describe it. It was a commuter and as thus had its own stairs for access / egress and as such the passengers had to stay on the bird until cleanup and the following accident investigation was nearly complete. The windows on that side were uh a very messy sight and those passengers could not help but view that. Thoughts and prayers to her family.
Did this happen at KBDR in the 90s?
Congrats
I am surprised this video come out of CZcams recommendation. I was thinking of the same question when I was boarding the plane a few days ago and was curious about the spinner on every jet engine. I made a mild guess to answer my own question. NOW thanks for confirming my guess.
This guy is cool. I always learn something new when i watch.
Great video Captain Joe! 😉
Please can you do a video on how planes navigate. I.e waypoints, VOR, SID/STAR’s
I really do not care about planes and stuff but listening to this guy is so nice
Very interesting, thanks for the video.
Capt Joe ! When you going to talk about your new airline and the aircraft you going to fly .
Awaiting impatiently to know 😍. I believe your TR is started?
Another great video man!! Keep it up dude I want to be a pilot and your very helpful!! Keep up the great work my dude!!;")
Thanks :)
Captain Joe your welcome dude one question are you a pilot in real life if not what's your real job?
Understandable and great idea.
It was cool that you mentioned one of my favorite airline, The Philippine Airlines(PAL)and I really wanted to become a pilot since I was 6 years old but since I am coming from a Financially challeged family, we couldnt afford flight schools.
It hypnotises an incoming bird to fall asleep and drop before it strikes the engine..
Simple logik haha
If you design a engine to keep the bird out of the engine like an arrow > blades
When I was younger, I used to be addicted to seeing those. So everytime I go to an airport, I always want to see the spiral stuff. I have an interest in plane engines.
I have only seen the G swirl and comma before
I once saw the whole Ubisoft logo on one.
So you saw a General Electric engine with a G swirl.
Wow just discovered this channel and I really like it!
Wow thanks Capt Joe for this very informative video. 👍👍👍👍
I've never heard someone pronounce apostrophe as "ah-pah-straw-ff"
lmao in Dutch and German you really pronounce it as APOSTROF instead of apostroFEE. Which can be very confusing since it's a word you use like 4 times in your whole life
This guy has worked on his english for a long time with several native speakers with multiple accents. It's kind of incredible, and you can tell he's thinking about how to pronounce every syllable.
Апостроф
I'm a native French speaker, and that's how you pronounce it. I cringed anyways.
Vladimir Harkonnen
Yeah I was about to say my teacher who was from France always pronounced it that way, but now I wonder, is that the way French people pronounce the English word, or is that just how the word is pronounced in French?
"You'd be surprised how many different shapes and sizes are out there"
Giggity
I just found your channel! Thank you so much for your explanations as, due to a heart/ear condition I cannot fly, I am fascinated by the topics you have raised. After a HORRIBLE landing in ATL (Hartsfield) by a co-pilot, I have to ask what your "worst/most embarrassing" experience as a new pilot?
That condor 757-300 model is beautiful!
*4:57* _The Dreamcast by _*_Sega !_*
APA-STROF! lol 4:47
I was gonna say that until you said it...
@BIG POINTS *_TIME TRAVELER_*
It’s so bad it reminded me Mike Myers character in View From The Top with his “You put the emphAsis on the wrong sylAble” line.
The comment I'm looking for
That was frickin adorable. Bless him 😂😂
The video is sooooooo great! I now regret didn't take airplane design/mechanics as college major.
Great video; thanks, Captain.
Going through flight training in the 90s in small propeller airplanes, everybody told me the markings on prop tips were for bystanders and ground crew, but the swirl on turbofans were for birds.
Funny how misinfo spreads and becomes accepted as truth!
Paint a fidget Spinner on that
Lmao
@Jack the Gestapo *massive crisis as jews avoid airliners*
@Jack the Gestapo *Trains compagnies profits skyrocket*
the planes fidget so much!
Paint
I'll try spinning, that's a good trick
As far as props go the markings also help fight prop mesmerization. Which is the movement and sound screwing with your ability to perceive distance and I have seen people almost be magneticly draw toward props by that phenomenon. I'm an ex c-130 maintainer by the way.
good pilot is always learning and calm.
3:50 missed opportunity to say "I'm no a bird"
Hiii,, I want to ask, what medical checkd does pilots need to go thru before flight?
Jokubas Lapkauskas a huge dick
FAA approved medical test
LOVELY that BF109 sound
Vee nice video Mr Captain Joe, keep coming...👍
With a version of the "apostrophe" design, it looks like a "engine being installed, please wait" website spinner.
Please can you make a video explaining about sonic boom
I will be glad if you make a video about it
Vikram Roy youre going faster than air can move away from you
Hey! I used to tow that precise Dash 8-300 at 3:04 I used to be tow crew for a decade. A little unexpected little surprise for me lol 😅
Music is love on a real train by tangerine dream. Nice choice Joe
Wow! A pilot so good looking like Captain Joe must be ‘the dream husband’ for many a girl and ladies! 😄
Sure if you want to spend time with him a weekend once a month. what to do with the rest of your time alone? Will either be faithful to each other?
Girls and ladies deram women will marry
Please make a video explaining what exactly happened with Malaysia Airlines Flight 370.
Sumedh Nandedkar nobody knows
In my opinion it was Pilot suicide but everyone should believe in his theory everything could happend to this plane
I know what happened :
They disappeared.
The evidence we have points to them flying in more or less of a straight line for a while after they lost radio contact, I'd guess something incapacitated the crew and the plane just kept on going straight due to the autopilot until it ran out of fuel and crashed in the middle of nowhere. Without actually recovering the plane we'll probably never know for sure though, so I'm not sure if there's much you could make a video about.
Gun Nut pt de Portugal não desse partido
Very interesting and good information!!
Thank you very much Captain :)
Oh. Well now i can put these on my bf 109s now.
Always when I watch your videos I enjoy then and learn something new Take a like from me :)
Magnificent video Joe keep it up
Thank you...I did wonder about this
Mentour Pilot did this but still I love it
Yeah, but the quality of his videos is so bad I can barely watch them until the end... I hope he will get much better in the future, though. But for the moment there is no overlap between Mentour's and Joe's videos, despite having the same topic.
jorehir I think Mentour’s quality is great, but Joe and Mentour explain the context of their videos differently. Mentour likes to explain it face to face with some pictures but Joe likes to give more examples with quick clips while talking over. There are some improvements that Joe and Mentour can make but of course it is your opinion but I think their quality and style of making videos is great.
Also Joe go’s into detail but his videos are styled for people new and into aviation but Mentour’s is more themed for people who are already into aviation so he explains using more terms but still they both go into great detail.
So, you _'still'_ love it? How generous. He's not nearly as brisk, collected and to the point as Joe. PLus the length of more than 9 min vs. 6:33. Plus he's this weird accent, revelling the unbearable rhotic _'r'_ because most foreign English speakers seem to think when they pronounce their _'r'_ very American-ish they'd sound like native speakers, while they don't care about all the rest of their pronunciation which is ... meh. Not so Joe. He practises a very native pronunciation indeed, so many non-native speakers wouldn't even guess that he's in fact a German. And just because someone else does sth. on YT doesn't mean anybody else couldn't do it better or at least differently, and if it was only to target a different audience. E.g. like me.
@@Claude-Eckel His mother is British. So hes half British
*Greetings from Finland!*
Esa Skykke *Torille perkele*
5:58 in addition, most of the time, they were setting up their attack runs, when possible, to come from the sun. The overwhelming majority of pilots shot down, never saw the attacker until they were already falling from the sky, or managed to bail out.
On top of that, even with "perfect" viewing conditions, it's hard enough to see the identification markings on planes till your up close and personal. You had to identify aircraft almost solely by their silhouette/shape.
5:35 - I was planespotting at DCA as a little kid, and I' pretty sure I was there when they released a falcon or something to scare away birds from the runway. Maybe I only saw it in a CZcams video, but IDK.
And on captain Joe planes there are fidget spinners
What a useful channel i found on youtube :) Captain JOE
True when I board a aircraft g swirl is very common for me
Very interesting, thank you.
