- Ever wondered why there are traffic jams in the airports? (besides when it's due to the weather)
The fact of the matter is that airports are limited by how often they can launch and land aircraft due to wake turbulence. In this video we will explore two different kinds of wake turbulence and their effect on the aviation industry. It's #NotWhatYouThink!

I feel the turbulence when another tractor-trailer passes me on the highway, I can’t even imagine how much turbulence an airplane generates. Very informative indeed. Thanks 😊
I'm a U.S. air traffic controller and was expecting typical clickbait cringe but this was actually well researched and an accurate description of wake turbulence and its effects on airport capacity. Other reasons for delays between departures though can include weather (if aircraft need to deviate a lot around nearby storms, we usually ask for extra departure spacing), and if two aircraft are going on the same route, we usually want at least a minute separation even if wake turbulence rules don't apply. Then of course you can have intersecting runways where another aircraft is about to land, so the departure needs to be held until that aircraft has vacated their runway. But good video overall.
I appreciate your comment. However, I would want to question the "MUST" bit in the headline. I have been on a number of flights where the plane would taxi to the runway and then just blast off without such wait. Guess that is when the previous plane has already departed 2 minutes earlier...
@@sp111973 Right, "MUST" is incorrect. Wake turbulence is only applied if the preceding aircraft is in a larger category. Most domestic passenger aircraft are in the same (large) category, so you'll really only deal with wake turbulence at major international airports where those flights tend to be in the heavy category.
@@kewkabe Hmm....i assume there are airports with multiple airstrips, one of which are specially reserved for these large airplanes?
@@divecolosio4988 A few. With two available runways, one is generally used for takeoffs and the other for landings, although if one is longer and an aircraft needs that additional length, that has to be worked around. If there are more than two, weight categories can be an efficient way to utilise them, although if local airspace is restrictive, it can be by arrival and departure route instead. Of course, "light" covers a wide range - even a Cessna 152 is "light" and so is Learjet. There is no way on earth I am not giving that Lear (or any other business jet) a healthy clearance on departure in a little Piper, Cessna or similar. His high-speed optimised high wing-loading aircraft is going to produce a lot more wake turbulence than I want to experience, even in a 150 Aerobat (rated for +6 -3g, and yes, I've been to both ends of that limit - voluntarily).
He is the one of the few guys on RUclips. Good content maker.
I don’t give a damn how long it takes to get off of the ground, as long as we can do it without crashing I’m happy doing it tomorrow.
Ikr. These people are trained to keep us safe. They know what they are doing. I never understand the idea of rushing that fking 3mn
Yeah, and let's be real, those few minutes are nothing compared to getting through security and boarding.
If you want a form of fast transportation where you get underway faster, it's called high-speed rail.
Traffic control is not to blame for unavoidable inefficencies of your chosen transit method.
I'm thinking you've never been stuck in the plane after leaving the gate for 2 hours.
Amen
why no one even thinking that lol? it called traffic ever hear of it?
One notable exception to the weight classification was the Concord. Even though its weight would have placed in the medium category, it had to be classified as a heavy because of the severity of the wake turbulence it produced during landing.
Same with the 757.
757 was mentioned in the video though I think, but not the Concord.
Droop snoot was powerful
@@kewkabe 757 has its own wake classification in the uk, it’s classed as an upper medium so between medium and heavy basically so an extra mile for separation
Heard turboprops generate more wake turbulance too although they're typically physically smaller than jets. That was why Singapore upgraded it's _Seletar_ Airport from a general aviation to a commercial one & moved all turboprop flights to there (from Changi Airport, so more takeoff/landing slots could be fitted there)
I'm a retired commercial airline pilot. This is a very good and accurate explanation. Well done.
I used to work at McDonalds and sometimes made the pancakes, I can confirm that this information is accurate.

That smoke test they did was fascinating! I knew about the wake turbulence and tip vortices but seeing them in action really displays how much of an impact they have on an area like a runway even 2 min after the plane has landed. Thanks for showing that.
Agree!

@@believeinjesus6972 false, one more try
@@believeinjesus6972 LOL!!!
That smoke experiment was very cool. But this also explains, however, why at tiny/quiet airports pilots with clearance just take off! I love rolling on to the runway and going immediately!
it also explains "testimonies" of people flying over the Bermuda triangle and "getting pulled into clud vortex" possibly a plane had passed through that route less than 2-3 minutes ago
The 757 is not even a wide body but puts out some of the strongest wake turbulence for some reason. One clear, calm night we were departing 08R in ATL in a 717 behind 2 757's and after the required wait we climbed out. At probably 800 ft agl the 717 rolled hard to the left, we received a 'Windshear' alert from Barking Betty and it took full right aileron to recover. One second later it rolled hard to the right, we received another 'Windshear' alert from Barking Betty and it took full left aileron to recover. Whole episode only took a few seconds and it was over.
Also, with 'reduced separation' of only 1,000 ft vertically ATC will often advise narrow body aircraft when they are approaching (Head on, crossing, etc) an Airbus A-380 super jumbo aircraft which has powerful wake turbulence. Many/most captains of the narrow body aircraft will ask for vectors off course to pass well away from the wake of the A380.
Excellent video! I am a former flight instructor and you've done a real service for the public by accurately explaining the safety issues around wing vortices!
as a former instructor can you tell me if a person can be a pilot if he is thin or have eye sight problem and what are the minimum education qualities of a pilot cadet
@@shinyeager2439: Regulations vary among different countries but generally speaking you will need to have an initial medical exam by a flight-qualified physician and this will include an eyesight test and an ECG (heart function) test. If you are red-green colourblind you will likely not be able to fly as these colours are used as identifiers in aviation. Correctable eyesight issues are not a problem, nor is body shape, size, or weight. To my knowledge there are no minimum education requirements. Happy flying!
@@shinyeager2439 I was in Air cadets for many years and done many flying lesson's in Tutor T1's ,For the medical part you will need to perform a health exam and meet certain conditions.It's Easy to get into Flying programs through cadet's also worth noting that way you can get some free lessons at the start and if your really interested, it could evolve into a really rewarding opportunity. If anything to do with Being a military Pilot your vision usually must be correctable to 20/20 vision. (Being short sighted and wearing glasses does not stop me from flying tho :) )
My Dad told me about vortices and how it's very important that an aircraft doesn't get too close to another aircraft.
Another thing I would also add is that an awful lot of people could do with learning about patience.
And a certain KLM pilot at Tenerife in 1977. You know the story.
Like Louis CK says on his joke.
Idk, flights are not cheap for me and good communication from the pilots is cheap. Between those two realities I think I can be a bit impatient when I pay a lot and get no communication from the pilots. (That said, I guess I also get annoyed when the city bus driver leaves the bus, us sitting for 15 min with no announcement & an empty driver's seat to stare at) guess it's just me
@@x--. yeah, your suffering from an age old affliction known to us older folks as……”ITCHY ASS”
@@mayorb3366 perfect example that resulted in something so horrific.
Patience matters, for sure.
At my Airport it's very rare to wait on the Runway. It's usually Hold Short, final announcement saying please sit back and hold onto any items. Then taxi out, line up and just straight into full power and get pinned in the seats. I love it!!!
Absolutely amazing video. Thanks 😊
Very interesting! I knew planes left turbulence in their wake, but I had no idea it was so extreme. The colored smoke really drove it home. Thank you for posting!

Fascinating video. Well done!!
As a student pilot I was departing Fresno CA airport. Just before liftoff the tower announced 87 Quebec be advised a C130 is departing on the right runway. I was thinking “so”? I was maybe 75 feet off the ground when the Cessna 152 I was flying tried to roll over. It took all the aileron control I had to keep the plane level. One of those unforgettable moments.
@@ezicarus8216 The ‘heads up’ was of no use to him. He didn’t understand the significance of the warning.
@@eddiebruv: I’m a bit surprised that 87 Quebec was given clearance to take off into that turbulence considering the dangers that ATC are supposed to control.
Having spent over 30 years in the world of aviation and flown countless times I speak from experience when I say passengers complain way too much, flight crews will always put safety first as they should and if people can't accept that then they can drive themselves to their destinations!
I appreciate you and what you do to keep everyone safe as there life is really in your hands!!!
The people who complain the most, know the least. They view the CEO's as greedy bogeymen, and the rest of the employees as lazy, thieving, and uneducated. It's pathetic.
There's a reason why there are more traffic accident on road than a plane. No wonder air plane is the safest form of transportation. Because there are too many idiot on the road, but they wont be qualify to fly a plane
I have watched enough air crash investigations to know that your comment is true in the vast majority of cases. But there are stupid pilots like the russian who tried to land with the window covered to prove he could land without seeing the runway and cheap companies that cut corners as well.
Shoot, even as a private pilot in a Piper Warrior I had to wait 5-8 minutes on the runway que as there were other light aircraft landing and taking off especially on Memorial Day weekend. Those 3+ minutes waiting on the runway is far better than waiting hours in traffic especially if there's a bad accident (caused by impatient and unsafe drivers)
I’m a air traffic controller in the uk, brilliant video. Where I work we have to achieve 10 mile separation between aircraft going down the same airway so they sometimes have to wait a minute or two even if there isn’t any wake turbulence
Is that because of the sector you will be handing them off to, because that is extremely excessive.
@@chrissede2270 yeah unfortunately, they operate a pretty busy airway so any aircraft we have going down there (most out commercial flights) have to be given that spacing. It’s incredibly annoying when you have a lot of departures to get rid of
Being a retired FAA Aircraft Dispatcher this is an imformative video. Depending trafic, weather and the airport, we pad theTaxi Fuel on the Dispatch Release at certain airports. Many airlines use 15 minutes of taxi fuel.
Your knowledge of planes is outstanding. Continue with the good job.
Thanks, will do!

A question i never asked but was fascinated to learn the answer to.
Thank you! I learned a lot from this video. Nice one.
Thanks for this great info!.. I’ve always wondered.. now I know and makes sense! 👍🏼
We just learned about this in flight class today. I couldn’t comprehend how bad the wake was but this helped insanely.
Just don't fly commercial. Don't need a pilot who can't comprehend
@@societydisorder3864 That is the reason why we are in Flight Class to comprehend. All Pilots can't comprehend at first, there is a lot of information we need to learn just to get our private pilot license (not to mention all the other aviation information we need to learn after private). So yeah, he can fly commercial after he finishes his classes and gets more flight hours.
I trained at a small airfield (Andrewsfield) in Essex where there was a major aiport within reasonable flying distance (Stansted).
I don't know whether it was just because of that proximity, but my instructor was EXTREMELY keen to impress on me just how dangerous jets can be. Mostly because they can be well gone before you encounter their descending wake vortices.
Worth paying attention the vidoe's claim that a 757 is a Medium, but is actually a Heavy for wake.
In fact, if you're flying a C152 like I was back in '99, it's probably just best to be cautious of everything. Including birds.
@@obstinateundead3931 hey. thank you. My biggest thing was at what point did the vortices dissipate in general conditions. How many feet can they travel. At what radius from an airport do you need to stay above jet wash. Etc. It’s a hell of a lot to learn and to use together at first.
@@societydisorder3864 hey you made a funny. Momma might just be proud of you now.
Absolutely 100% accurate! I have seen wake turbulance from a medium sized airliner flip a Cessna 152 completely over when it failed to wait for the vortices to dissipate. They are more powerful than you think, and last longer than you think. From an ex pilot.
Damn! Now I will patiently wait every time I am on a plane instead of getting annoyed like I used to 😅
@@spektred This never ever bothers me. I have been on flights with delays. No big deal. I look at it as, they're doing something that's for our safety, so be it. I just look out the window, or talk...
@Neil Foster: The only thing you have to worry about when flying a C152 is whether there’s a small duck or a dragonfly taking off behind you that might get it wings ruffled, lol. You don’t have to worry if one took off ahead of you because you’ll run out of fuel before you catch up to it anyway!

Great video. I learned something today. Love your content.
Very useful and informative video for common people . Thank you for sharing 👌👍
This is interesting. Thanks for providing it. I and everybody easily knew why back in the 1950s/‘60s’ when the cockpit command crew paused at the foot of the runway’s taxiway for awhile before making the turn to take off.
That was to individually rev each engine on the plane to high power to check the gauges for performance. Then, make the turn and let’s go! For me, this was mostly American DC-6s and 7s at Dallas Love Field. And once on an Eastern Lockheed Super G Constellation at the old Amon Carter Field in Fort Worth. THAT was neat for a kid. It was a night flight. I could see blue exhaust flames coming out of the engine, alerted the stewardess, and got to sit on the first officer’s lap while he explained how it all worked.
He joked that his job, as first officer, was simple. He pointed out that there was a green light at the tip of one wing, and a red light at the tip of the other. His job was to make sure the captain kept flying between those two lights.
I was only in second grade, but knew it was BS. 😝
While I'm no engineer, I do fly a lot (not in the last year and a half though). Thank you for the information. Very clear and very easy to remember!

Great illustrative photography supporting very interesting information.
So, when the DC-10 wasn’t busy crashing it was causing other crashes? Yes.
A level of efficiency other manufacturers can only dream about
I don't remember the flight info but there was one case when a DC took off before a Boeing. A piece of the DC fell off and cause the Boeing to crash. pathetic
@@tailorforeman7082 same story caused the crash of a Concorde, grounding the whole fleet forever. Beautiful machinery brought down forever by junk from that joke of a plane.
@@GaneshKumar-bv2td sorry yes, it was the Concorde not an Boeing
!
It was the opposite of that. It was in its design stages for well over a decade, it blew it's budget massively and it was one of the most reliable planes out there, with only one crash, which wasn't even its own fault.
It was and is a beautiful plane, arguably the most beautiful passenger plane to exist.
When I lived in DC We used to go down to the park right under the approach of WDCA Regan. After a good size airliner passed overhead you could actually hear the wingtip vortices passing by overhead and sometimes see them moving across the field just like a mini tornado and see them transition sometimes from horizontal to vertical. These were strong enough to easily flip over a smaller plane and if you stay inside one long enough flip another airliner. These are powerful suckers and can intensify long after leaving the wingtips.
I feel like if one tried to go plane watching today you would have PD or suits&sunglasses show up and start thinking you are there for terrorism.
Honestly I've always wondered this. Thank you. ♥
Very informative ! .. and well done !!
an addon to this: i sometimes fly out of an airport where the smallest aircraft are ultralights and the largest are 737s. the tower almost always makes the small aircraft takeoff before the jets due to wake turbulence...it always seems funny taking priority in a cessna over a southwest jet
That is very ironic!
If the light is VFR then this is great, if it’s IFR and you don’t have a way to get a good separation then the medium goes first and the light can wait.
When we fly the cessnas out of Boston, I wondered why they let us go…nice to know after watching this video.
My first flight lessons were out of Hancock International Airport, Syracuse NY. Back then, the NYANG Wing next door to our FBO at the airport flew F-16s, so my plane (usually a Piper Warrior II) was sometimes either queued-up behind or in front of a fighter jet on the taxiway. It makes for interesting takeoffs when you've JUST started your takeoff roll and the tower tells the fighter to "position and hold" right behind you (now I guess they say "line up and wait"). You have this overwhelming urge to make a clearing turn of your own as soon as you get off the ground because you know that fighter is burning jet fuel waiting for you to get out of the way.
Just remember it is a public use airport paid by public taxes. Small aircraft have just as much right to use that airport. Southwest is just a company trying to make money the same as Joe Blo’s flying school. Because Greyhound busses carry more people than your car, does that mean they get priority over you on the interstate highways that are paid for with your taxes?
I have been waiting behind airliners for takeoff in my Cessna, as well as put in front of them. It all depends on how the controller sees fit as the best way to expedite traffic flow.
Many years ago I worked near an airport and some days I would eat my lunch very near the runway and watch the planes. One day a 777 came in to land and about 30 seconds later there was a really weird build up of wind and very strange sounds it crossed over the top of us you could literally put your hand out and feel it and see it too kicking up leaves and dust it was crazy. Its the only time I ever felt or saw such a thing but it made me very wary of wake turbulence since that day. The whole incident lasted about 30 seconds and I visited the same spot lots of other times and never saw or felt anything again. I guess that day the winds and the conditions were just right.
Ever seen the movie Pushing Tin?
Thank you for the information.
XLNT and informative. Kudos!
We've got a casino here in Reno, Nv that's about a mile from the end of the runway. If you stand beneath their trees and wait for a large jet to pass overhead, you often notice that the jet is on the runway and hear the wake turbulence blow in the trees above you.
I have to say I was surprised with the accuracy of the information you passed here and also the portfolio of videos you gathered for this video. Very well done!
I learned about wake turbulence as a student pilot, but never saw that smoke demonstration before! That’s a great demonstration!

To add to this, helicopters operating off small ships (Frigates, Destroyers, etc.) must take into account the turbulence created by the ships superstructure. I watched our helo loose Tail Rotor Authority due to winds exceeding 45kts over the bow of the ship. Fortunately, as the helo's tail was spinning around the main rotor, the helo managed to lift off the deck and away from the winds and regain control.
Hi John,
Do you know the cause or can you speculate the cause the loss of the Helo off the deck of the USS Abe Lincoln off San Diego a few weeks ago?
@@penelopelgoss2520 From the scant details given by the local news I only know the the helo was trying to land, there was some unusual side swaying (?), the rotors blades struck the deck (which caused the injuries on the flight deck), then the helo went over the side (90' drop). I suspect some sort of mechanical or equipment failure with the flight controls. But without seeing film I can only guess.
The investigation could take months. And I'm 25+ years past having accesses to Safety Magazines and reports that would cover things like this.

Actual measurable testable science, as opposed to wild ass guessing and stentorian toned pronouncements, refreshing and hope inspiring. Excellent content sir
You can ask a flight attendant she/he will tell you why they wait. sometimes the capt. or co pilot will announce why they must wait. at least the few planes i been on did. they compared it to a wake of a boat or trying to drive a small boat behind a bigger boat.
@@CertifiedForkLiftOperator69420 This has some misleading data. There is also separation issues. Same type a/c can depart immediately after take off, if course diverge by 45 degrees or more immediately , if within 5 miles the 1 minute. The wait is not always dependent on wake turbulence.
Thank you for clarifying this for us ALL. now that we know this, we will be more tolerant. Thank you again.
Nice video. And I liked the demo of the vortices with coloured smoke.
Thank you for sharing ❤️ 😊
00:31 - DCA! That's the new Wilson Bridge down past the end of the runway. That little park at the north end of the airport is a great spot for plane-watching.
The wing tip vortices also produce drag, which is the main reason the airlines wanted a solution (save money on fuel). That's why airliners now have winglets to reduce the vortex and reduce the drag.
If you watch the video again you'll see that the aircraft producing the largest vortices all have a flat wingtip (no winglets).
Cool, thanks for sharing. Always wondered why those exist.
