Turbulence Explained

This videos looks at the basics of Turbulence, what causes it and what affect it has on an aircraft. Turbulence is created by chaotic changes in flow pressure and velocity which causes "waves" of air in the sky. As planes pass through these waves, they experience bumps and vibrations which is how passengers experience air Turbulence.

I experienced an "extreme" one I think. From then I've had fear of flight which only seems to increment every time I fly. It was at night going to Lima, all you could see through the window was complete darkness with the occasional lighting that eerily lit everything up. The plane was shaking heavily, babies crying, women screaming, luggage rolling from one side of the plane to the other. The pilot himself sounded extremely nervous repeating over and over "please stay calm! please stay calm!", the flight attendants look scared too. It was pretty awful, I don't wanna die in a plane crash.

[@Doofer911]

Yikes, if it's any comfort, it's very very unlikely that an aircraft will experience a major problem in Turbulence. Aircraft are built and tested to extremely high safety standards and manufacturers design and build aircraft which EXCEED those safety standards by a long way. Aircraft are also maintained to very high standards as well so there's very little risk that an aircraft will have an issue in turbulence. It might be worth watching a video of a "wing flex" test so you can see just how much an airplane's wing can move safely.

[@sebaba001]

Thanks. I think I have to fly soon :F.

[@peter58peter]

So true. Turbulences, around Peru and rest of hot continent can be really powerful.

[@wendshield]

I am not a happy flyer - seeing with my own eye's wings bent like that really helped me see how well-made planes are. I enjoyed this video and I appreciate your time! Thank you!

[@alwinpriven2400]

I like how the video is 7:37 long.

[@astrozulumike]

Alwin Priven and notice that the video thumbnail shows a 737 too

[@Doofer911]

Haha, what a coincidence!

[@lesliepattison1814]

Alwin Priven a

[@cadenorris4009]

Alwin Priven lol

[@sarathw5740]

It is funny when you say "water bottle is most definitely lost" By the way I love your videos.

[@MagnoSauce]

I just finished this playlist trying to learn for MSFS2020. Thanks for doing this, your videos are both informative and pleasant.

[@annabelb1d]

Why did this make me even more anxious

[@Claude-Eckel]

I spent a good ammount of time with this damn powder game. Placed some _'fighters'_ on the ground and created the greatest mayhem of turbulences, shear winds, clouds... followed by heavy rain, winds and airflows, explosions, acid and mercury and was astonished what all that did to my test objects lol.. can become very time consuming. Great find. Thx for the tip!

[@Doofer911]

I did warn you that it is addictive! haha, but yeah it's an intriguing little game!

[@zakriyamahamooth5329]

Best explanation I have heard after 75 yrs😳😱👌

[@michaelromano3920]

Love the videos man! I've made them a part of my daily routine and hope to use the knowledge as a good base line before pilot lessons!

[@johnmitchelltaus]

I'm new to FSX and have found the lessons a little boring, all that reading, I just want to fly. Then I found your tutorials, Brilliant!!! I really think you have done a great job especially not being a real pilot. Your tutorials have explained a lot of what was confusing me, in a very simple and informative way. I think FSX should include your lessons as well. Keep up the good work, we really appreciate it. Maybe one day you could post some updates to this series.

[@Doofer911]

Hi John, thank you very much for your kind words. Unfortunately, FSX hasn't been developed for a long long time so there's no chance of my work being featured in the game but I'm currently looking to engage with some of the top add on developers for the more modern flight simulators to start creating some bespoke tutorials for their products. Also, I've just secured a job which will give me a deeper, real world insight to flight training and instruction so I may come back and make some fresh videos with newfound knowledge and experience from real life, not just self-study on the internet etc.

[@johnmitchelltaus]

Can I ask you what you mean by "more modern flight simulators". Do you think FSX is becoming outdated and is there a better flight sim out there? I bought FSW but we all know what happened to that, what a great shame. Even though I have quite a bit of Orbx installed, I am still disappointed in the Environment and textures in FSX. I thought with a high end computer and high end add-ons the game would look more realistic.

[@Doofer911]

Well the two leading simulators at the moment are Lockheed Martin's Prepar3D (P3D).... it's an evolution of FSX however it's marketed towards professionals, so military, police, search and rescue services etc. However it is also available to the general public and many of the add on developers (Such as Orbx) who worked on FSX now develop products for Prepar3D because there is still a large public market which uses it. Many people who flew with FSX previously have now migrated to P3D... myself included. FSX is now about 10 years old and was developed in an era where we didn't have multicore processors and 64 bit Operating Systems. So even with powerful, modern hardware, FSX isn't programmed in a way which can take advantage of the extra power. P3D is very much like FSX however it's been redeveloped to take full advantage of modern hardware. Along with that, you have X Plane 11 which boasts a more realistic physics engine which drives aircraft "feeling" and behavior in the air. In the past, X Plane was always for a more hardcore simmer who already knew what they were doing and what they wanted from their sim experience however X Plane 11 is a lot more user friendly and has much more appeal to newcomers.... so the community and general interest in XP11 is growing day by day.

[@johnmitchelltaus]

Looks like I need to invest in two new games. Maybe a topic for one of your videos, comparison between the three.

[@alwinpriven2400]

I remember my first experience with turbulence, my flight to Austria. It was quite fun and it was light (probably).

[@AFKplayaz]

Hey mate, I know this is an old video but it’s done very well!

[@wrdfanbasilone4139]

keep up the good work! I'm rooting for you to achieve your subscriber goal!

[@mdshayan8749]

Make a video on space shuttle landing that sounds awesome

[@JP-sx9nf]

I like the way u respond to every comment.thanks for the video

[@Doofer911]

Argh! Just come to this video and seen this comment! I apologise for not responding 9 months ago. Sometimes KZbin doesn't show me comments and it doesn't make it easy to respond to comments sometimes, hope you don't mind this one being 9 months late!

[@davidroberts1852]

Well put

[@kristijank2780]

Thanks.Very interesting and informative as usual.

[@Doofer911]

Glad you liked it! :)

[@dreamerweaver]

Went through severe where a flight attendant hit the top of the aircraft bulkhead and then fell on her back. Though that'd be my last flight. On decent to Norfolk, VA.

[@Doofer911]

Yikes, normally pilots will turn on the seat belt sign if they anticipate turbulence but you can come across something called clear air turbulence which you don't see on forecasts and there's no other visible sign (like a particular cloud formation). That's probably the most dangerous form purely because it's completely unexpected and if it's severe enough then it can cause injury if people are not seated with their belts on.

[@theowl2326]

mom: how do you know what turbulence is ? me: 911 taught me

[@Doofer911]

You do realise it's nine one one right? not nine-eleven.

[@theowl2326]

Yes °~° Lol

[@NoFaithNoPain]

Nice explanation. A much easier topic than lift LOL

[@shanebadal305]

keep up the good work bro

[@Doofer911]

Will do, thanks for watching and for your kind comment!

[@Nole2701]

im getting turbulence flashbacks and im getting dizzy from just hearing the word "turbulence"

[@travis8511]

could you please make a vid on how to fly the f-18?

[@davidaranguren108]

Loved it

[@MistorGator13]

5:03 3000 miles SQUARED...or 3000 SQUARE miles? I get confused

[@VunierDJIPhantom3]

Have you ever been in turbulence where the plane movement was so sudden and unexpected, if you had been unbuckled you would've hit your head on the ceiling?

[@Doofer911]

Not really, there's two flights that stick in my memory for having sudden, significant moments of turbulence but I don't think it was so bad that it would have thrown a person off their feet.

[@mettlecrusader29]

Vunier DJI Inspire yep happened once all of a sudden that too in the middle of very light/ no turbulence. some of us hit our heads on the ceiling :)

[@5327indarkness]

Vunier DJI Inspire why would you even be up during that anyway? they tell you to buckle in,that's your fault for not paying attention

[@VunierDJIPhantom3]

+the electric knight the seatbelt is uncomfortable

[@aljack1979]

They still can't detect '' clear air turbulence''. They know what conditions contribute to clear air turbulence but can not detect it properly... Yet. I remember seeing a documentary about Chinese scientists who are trying to develop a forward facing radar type of equipment that will help with detection.

[@Doofer911]

Agreed. I think what I was talking about in the video was areas of obvious turbulence such as hurricanes or the boundaries of a jet stream for example.

[@Crusader1835]

You wrong, at least when I've flown the pilots usually let the passengers know when the plane is approaching a heavy turbulence and thus to fasten their seat belts, and even they tell you for how long will it last. They usually describe the turbulence as a "bumpy" ride.

[@aljack1979]

Crusader1835 If the pilot's are aware of turbulence then it will be from their weather radar which picks up cloud moisture so they can see the weather ahead. Or they have information from aircraft flying the same route ahead that they have experienced some category of turbulence. Sometimes it can updrafts from mountainous regions. I've been flying in clear sunny(not a cloud in the sky) conditions over flat land and experienced mild to moderate turbulence. This would have been due to either the heat reflecting from earth or crossing jet streams(winds high up than pilots to fly in). We were at 37000ft and probably crossed a different wind stream that was going in a different direction. This clear air turbulence is difficult for pilots to identify.

[@Doofer911]

Crusader... we're talking about Clear Air Turbulence which is much harder to detect than other forms of Turbulence and is predictable. If you look at any significant in-flight accidents where passengers have been injured if they weren't buckled in their seats... most common cause of such incidents is Clear Air Turbulence. If Turbulence has been predicted or reported by pilots who have flown through a particular area of airspace earlier in the day, then pilots on subsequent flights will advise passengers to buckle up.

[@androeleazar4662]

how did you learn about aviation?

[@Doofer911]

Self study on the internet.

[@androeleazar4662]

Doofer911 when did you start to learn about aviation and what encourage you to studied aviation

[@Doofer911]

I've always had an interest but itvwas probably about 4 years ago when i started doing flight sim videos on the channel is when i started studying properly. I want to earn a pilots license one day so I thought I'd learn the basics using flight simulators.

[@BipsCricket]

What is windshear?

[@treborhg_9381]

when the wind direction and speed changes suddenly

[@ranggaalr]

Are going to stream today?

[@Doofer911]

Will probably stream this week, one un-announced to test some settings and one this weekend.

[@Weaseltube]

Would have been worthwhile to cover wake turbulence as well. Also, is either type of turbulence simulated in flight sims?

[@supertminecraft8675]

I know normal terbulence is, but I'm not judging afp95's trolling videos to confirm if there's wake turbulence

[@michaelyoo3366]

I think you should avoid putting definitions and Wikipedia links at the start of each video. Personally, I'm not interested in definitions, I'm interested in intuitive explanations!

[@alikombi6781]

I shall only Fly on an a380 then!

[@josephstalin4202]

I love turbulence, it's fun

[@Doofer911]

Depends how you define fun lol.

[@23igna]

It is fun if you survive

[@RedUSMarines311]

landing in Maui during the trade winds at Max potential will literally make u shit yourself, I landed in Maui lastnight and oh my gawwwwdd.

[@Doofer911]

I'd love to visit there for real one day :) Hawaii looks like a beautiful place!

[@Defeft]

Where in Scotland are you from? Thats a pretty weird accent lol

[@Doofer911]

The Highlands however it's kind of a weird mix with London now :/

[@crashlandy9582]

He length of the video is 757 get it Boeing 757🤣

[@Doofer911]

Haha, unintended coincidence! :)

[@NotNibrasakhi]

lol powder game

[@tkosmider]

First

[@omnambiar1765]

Are going to stream today?

[@Doofer911]

Will probably stream again this week, will do one un-announced to test some stream settings then a proper flight this weekend.
