You may have noticed little numbers popping onto screen throughout the video. These are referring to references in the description of the video. This was inspired by my friend, Simon Clark. Specifically this video: czcams.com/video/xYTvMWtmdnE/video.html Props go to him for the clever technique.
I really like the initiative! References should be commonplace for any informative content
You should look at Boston's Logan International Airport. It is formally one of the busiest airports but has lost popularity primarily because it defies all the things you talked about in this video.
Some airports like LFSB have runoff areas which are used as taxiways but could be used as a shit-the-pants extra room.
References are essential!
Real Engineering I just have to say, if you buy a house next to an airport and then moan about the noise then you're an idiot, and I don't see why they don't bulldoze most of the villages around Heathrow to pride the space it needs .
Fast and Furious Style
30 km long runway
That runway would actually extend from Barcelona in Spain to Moscow in Russia. That's an enormous distance, even for a straight road (or in this case runway).
That Bad BLU Spy I dunno man 30km is about the distance from the statue of liberty to the sandy hook peninsula
I was talking more about the runway from the actual movie. The FnF Crew could've easily gotten where they wanted to go if that runway was pointed somewhere else and placed with one end on a coast. There's even a Forza game, Forza Horizon Presents Fast & Furious, that has an achievement for completing it's final mission. That achievement is titled "How long was that runway?" as a reference to the jokes about it's calculated length.
you could have multiple planes landing at ones at different points/ problem solves.

Circular runways. 13:25 “These are the kinds of issues that come about only after engineers carefully analyze the design”
I don’t think it takes much thought to shoot that one down.
If anything, it should be a octagonal runway or a hexogonal one
When you have seen some of the crap engineers come up with..
Or have to explain to one how a siphon works... Then you'll understand why an engineer would actually design a circular runway and think it would work.
@@thebravegallade731 it will create the same problem
Well... The circular runway is not as crazy as it initially looks.
For instance, there'd be no such thing as a crosswind, you'd always land and takeoff with a headwind. A variable wind direction would of course still be challenging.
The biggest downside of course is the footprint, to make the idea realistic, you'd need a truly enormous runway, like 8-10 km diameter. So that means up to 4 times the footprint for just 2 runways. Perhaps you could make up for that by having a second inner - ring runway for domestic/shorter flights, but it would be still a crazy large airport, very wasteful of space.
@@CocoDaPuf try a circular runway in a flight Sim. It is far too dangerous and will never happen.

Maybe my favorite video of yours that you’ve made so far. Incredible job

Great job at boiling down the complicated world of airfield design. I will be using this for the foreseeable future to help explain exactly what my job entails!
Thanks for using the metric system!
Yea, cause aviation does not.
would have preferred the use of knots, but hey.
This is probably the only time he should have used feet and knots...
i love your videos sooo much, i love just listening to you going through all these different engineering problems, and the animation is amazing!
Check your facts about the balanced field length. It simply means that TODA, Take Off Distance Available equals ASDA, Accelerate Stop Distance Available.
Take Off Distance, TOD, is the distance required to accelerate, lose an engine one second before V1 and then continue the take off to a height of 35 feet above the end of the TODA.
Accelerate Stop Distance, ASD, is the distance required to accelerate to V1 and then stop again.
Yup, couple of things went oversimplified in the video.
Related to this, the amount of time to stop is not related to the amount of time to accelerate to that velocity, since the engines accelerate you, but the brakes are what stop you (plus the engines in reverse mode potentially). Those numbers have no need to be (and won't be) exactly equal.
shuldnt it be TODR = ASDR? cuz TODA does not have to equal ASDA
Correct. Also, FYI, reverse thrust is not added into the required stopping distance after a V1 abort.
@@tbmavengerstuka Since Engines could fail leaving no thrust with which to reverse...
I must say, I constantly think of this video. It’s easily one of the most fascinating things I’ve ever watched. Anytime I see an airport, or am talking about airplanes/air travel, or anything like that I instantly think of this video and feel like sharing this information with people because it’s so cool. Amazing job
moral of the story, runways are long and every little factor makes them even longer
Awesome video and well explained!!
8:10 that moment when spoilers are raised how quickly aircraft lost it's lift. I know it's obvious but it's fascinating to see it.
Nice catch! It really demonstrates how much the spoilers... er.. spoil the lift of the plane and allow it to set down
Great catch, thanks for noticing that!
Especially on a plane like that (787?) where the wings flex up as the result of the lift they experience
At this point of landing procedure the spoilers are called lift-dump!
it's insanely effective indeed, as a commercial pilot I always feel when the spoilers go up, especially whith a smooth landing because they're set to deploy as soon as the ground sensor ... well... senses we are on the ground (that there is pressure on the wheel) and that the wheel is spinning. It's mainly used to increase effectiveness of the brakes, otherwise the wheels would skid too easily (some runway excursions occured only because the spoilers weren't armed and deployed)
12:30 southwest landing was pure butter soft...
I always love flying through Atlanta. With those five parallel runways, other airplanes taking off and landing left and right of you. It's like jet speed drag race.
In my opinion, this channel is really underrated. All of the videos on this channel are incredibly interesting and it makes me want to watch even more. Keep up the amazing work!
But what if we put an runway on top of an runway?
and what if we put portals at the end of every runway
How will you do that?
Runway-ception.
Edited your comment and still messed up. Smh
Johnny Wynn you have no idea how many fucking comments he has it’s fucking crazy
Great Video! Would have also loved to see more detail on the actual engineering of runway, like types of asphalt used, rain water drains, all the lights and maybe this cool anti runway overrun material.
Learning a lot here. this channel and Wendover are taking my time on youtube lately and for good reason. great content. Keep up the good work
Love this! Makes me that more interested in aviation and commercial air transport. Thanks for sharing!
before v1 it is optional to RTO but after v1 It is a MUST to NOT ABORT takeoff and after 80 knots only serious issues like Engine failure Wind shears and flight control malfunctions can RTO while light issues like blown tires have to Continue with takes off
After V1 its only a must to not abort takeoff, if the aircraft is control- and flyable.
If you lost a wing after V1, you dont have to takeoff
This video was really amazing! There's actually another consideration that you could include in your runway length calculation regarding the balanced field length.
I've never actually heard of that term before, quite possibly because most aircraft do not require the same amount of distance to decelerate from V1 to stop as they do to accelerate from start to V1 (or possibly because I live in Canada, not Europe). This is because an aircraft uses its engines to generate the accelerating force while it uses its brakes to generate the decelerating force. In all cases I can think of, an aircraft's braking system is actually capable of generating a greater force than its engines are, meaning the distance required to stop is less than the distance required to take off. Although larger aircraft also have reverse thrust systems capable of contributing to a decelerating force, pilots are not allowed to factor reverse thrust into their V1 calculation because not all conditions will permit using reverse thrust, primarily contaminated runways (This may not be the case everywhere, as not everywhere gets as much snow as Canada, I'm only speaking from my experience). This means in the case of an uncontaminated runway there is a bit of extra margin of error and it also simplifies the calculation to determine stopping distance.
For reference, I am not an engineer, I am a student pilot with approximately 200+ hours, all of which are in a C172. Assuming a standard atmosphere (29.92 in-Hg, 15 degrees Celsius, sea level, no wind (sorry for the mixed metric/imperial, blame Canada)), a C172S model has a start to wheels-off distance of 960 feet, while it has a rated wheels-down to stop distance of only 575 feet. This isn't the EXACT same as a V1 calculation, but the theory still applies.
For larger aircraft, the difference between the accelerate distance and the decelerate distance is usually larger. This means you can make your V1 decision point a bit further down than half the runway, allowing airports to get away with operating larger aircraft on shorter runways.
Let me just reiterate that I loved this video and I mean you no disrespect, I just know you'll find this /half as interesting/ as I do!
Brilliant video, I really love the presentation and the way you make everything so simple to understand.
Really enjoying your videos. Keep up the good work mate!

Incredible video! Informative! Physics is considered the most vital of building an airport. Lacking the calculations of the temp., airplane crash. Neglect wind resistance, crash.

You got it in reverse.
alright then, I guess his just showed up in my recommended earlier.
Great video as always btw!
airplanes are better anyways
Also Mustard.
Balanced field length is NOT twice the distance to accelerate to V1. Balanced field length is, in simplified terms, the distance to accelerate to just before V1, lose an engine and stop or equally, continue the takeoff and climb to 35 feet, either option requiring the same distance because that is how V1 is defined. That distance is the balanced field length. It has nothing whatsoever to do with being twice the distance to reach V1.
yeap, finally someone who recognized the mistake. well i guess for any non pilot that's a very complicated subject.
Thank you!! I was looking frantically for a response like this, everyone is complaining about a380 not being the largest a/c, but nobody mentioned this...
In very simple terms the balanced field has nothing to do with the distance, but with the speeds;
From 0 to v1 to 0 (your stopping distance) and from 0 to v1 to “liftoff” (your go distance). When they both have the same distance, it is called balance field.
For some perspective, if from 0 to v1 is like “1000m” you can expect v1 to 0 or v1 to liftoff to be “500m”, it is for sure a big amount shorter then reaching the v1, so the distances are never the same :)
I was wondering, “it doesn’t take the same distance to stop, it takes more”, but I don’t know. Seems like, even with spoilers deployed, the breaks could nowhere near top the thrust of the two, or four engines.
No it's the other way around. It takes less distance to stop than it does to accelerate. The stopping power from the brakes is more than the acceleration power from the engines. This doesn't even account for spoilers (which make the brakes more effective) or thrust reversers.
Troy Baxter some fully loaded passenger planes can do 20-100 km/h I’m 5 seconds. Can they really stop that fast?
This was a great educational video and extremely well done. Thanks for sharing. Keep up the great work! 👍🏽
Your aeronautical knowledge is incredible you even had an AC as a source. Fantastic job
Istanbul New Airport also will have 5 parallel runways once all the phasses completed. Right now, there are 2 parallel runways, which are 4100 m and 3600 m along.
Pretty useless now that Turkey is turning into a radical Islamic dictatorship, it wouldn't take long before no one will go there anymore, just like 2019 Iran

The pandemic has certainly affected the need for a Third Runway, as it has for the need for the HS2.
Hopefully, movement restrictions will continue to reduce the need for interconnecting infrastructures like additional Motorways.
there's certainly a need to limit aviation's contribution to the climate emergency

One of the best 'knowledge/educational' videos I have ever watched!
Your videos keep getting better and better
I'd never considered airport altitude or temperature before.
They both play a HUGE role in day-to-day flying. The difference in performance from low altitude airports, to high altitude airports is massive. Same with cold temperatures vs hot temperatures.
Its the same in sports. Denver or other high altitude fields have massive advantages. For example, the ball can be thrown further, and in soccer, in South America, the national team of Bolivia play at 3,637 metres (11,932 ft) above sea level, making it one of the highest football stadiums in the world. Many visiting teams protest that the altitude gives Bolivia an unfair advantage against opponents. Same would apply to every other aspect, including aviation.
MrCheddahcheese correct, and to get to La Paz you need to fly to El Alto airport, which is in a neighboring city even higher than La Paz itself, at 4.061m (13.323ft). I’ve been there a couple times and always had a mild headache because of the altitude.
Some (like Denver - KDEN) are considered "high and hot" airfields which is why it has five runways at 12000ft (3658m) and one at 16000ft (4877m).
@@MrCheddahcheese Actually high altitude airport are at a massive disadvantage. For takeoff, the thinner air reduces both engine thrust performance as well as wing lift and control surface effectiveness. For landings, the same final approach speed is actually faster due to the change in pressure /density, known as ‘true airspeed’. So an indicated speed of 130 knots at sea level is 130 knots, at 5000’ elevation an indicated speed of 130 knots could be 150 knots or more of true airspeed. This results in longer landing distances to bleed off the speed and braking energy.
For a moment I thought this was a video made by wendover production! Thanks for the interesting and informative video.
This video documentary is genius! Good job!
I was at Phoenix Sky Harbor during the runway closures in 2017 due to the excessive heat. In addition to the runway closures, aircraft were having trouble cooling the cabins of their planes in the heat. Surface temperatures (including heat reflectivity off of the tarmac) were reaching 60*C. I was able to book a flight out of Tucson to DFW and had time to make the 2 hour drive there and get through security, board and take off before the runways reopened at Sky Harbor that evening.
I don’t think the FAA has much to say about runway spacing on Heathrow ;)
Maybe for N registered aircraft?
Paul Furey I believe the registration of the aircraft has no impact on the regulations that the airport has to comply with. FAA is the American aviation authority. In Europe we have EASA regulations to comply with.
FAA sets the international standards
@@oceanlnr9414 It does not. ICAO does that.
@@oceanlnr9414 The world doesn't revolve around the US thankfully as the 737 Max has shown the FAA is corrupt and cannot be trusted.
Holy crap, from that Tibetan airport, you're pretty much already halfway to your cruising altitude. O_o
And at lower than cruising cabin pressure. I wonder how that will troll the pressurization system.
@@bskull3232 from what I know, airplanes landing or taking off at high altitude airport will have a special setting to prevent oxygen system from activating on ground.

shahmeer khan yup. It uses pneumatics. Pressurized air. The aircraft is held by a piece connected to that system. The air is released and the aircraft speeds up like lightning. It actually reaches 220 kph at the end of the runway
Looks like rocket boosters are BACK on the table boys..!! :D
I am surprised Denver international airport is not mentioned here. It is a relatively young airport, and was built a long ways outside of the city in order to accommodate massive expansion. Currently it has four parallel north/south runways, all at least 3,658m long, and the longest at 4,877m. It also has two east/west parallel runways, both 3,658m in length. The airport is designed to be able to expand to six north/south runways and four east/west runways. Another very neat design feature is that it is possible to taxi between the terminal and each runway without the need to cross other runways, which makes the airport far safer as the risk of runway incursions is significantly reduced.
Interesting about the headwind idea. My local airports IAH and HOU have runways to operate E/W or N/S. The airports normally run E/W but when there is a large storm system in the Gulf of Mexico the wind shifts to N/S and the other runways are used!
Just to let you know - you referred to FAA guidelines when talking about Heathrow, as Heathrow resides within territory of the United Kingdom you should refer to CAA guidelines.
EASA
Headwind doesn't reduce the power needed for a proper takeoff roll, but does reduce takeoff distance. The engines still need the same power to propel the aircraft through the air. Airspeed vs groundspeed.
Kiimosabe actually, most airliners will try to use the least engine power for the runway available. When the headwind is stronger, the engine can be set to a lower power setting.
Very nice video, Its really interesting!
The only thing is, according to OACI, the minimum separation distance between parallel runways for instrumental flights range from 760m to 1035m, depending if its a parallel segregated operation (lower margin) or independent paralell approach (higer margin).
Just noticed this thing preparing for my exam of airport's engineerig subject heh

And then you have Schiphol, three runways north south and the rest all over the place
YYC is north south as well
Yes that is true, but in Calgary the dominant wind is north south, where as the Netherlands has mainly wind from the west.
Similar thing in Dallas, TX at their DFW airport. 5 North-South runways used daily simultaneously (2 Take-off and 3 Landing,) and 2 angled ones only used when needed for winds usually. The predominant wind in Dallas, TX is a southerly flow from either the Gulf of Mexico or "Actual" Mexico from the south. Most Gulf-Coast or nearby inland airports have an option to land N-S.
the far west runway takes so long to taxi from and to ....... youd think after you land you're almost off the plane but nope....
Before ORD began a 'cleanup' procedure the runways were all over the place as well

Very interesting and easy too follow ! Thanks
Make a video on runway material design to withstand the daily impact of hundreds of hundreds-of-ton planes, please?
That would get complex and boring for most people real quick. :P
I thought this was the topic, too. 😀
Its not really a special material, a runway is (simplyfied) a very thick road
As long as it's not as short as Saba's, we should be fine.
Vmc, a yaw and roll into the inop engine. But other than that pretty good V speeds. Balanced field, accelerate-go, accelerate-stop, and others are pushed into certification of total runway length needed for air carriers to use that runway.
To be a little more accurate, speeds, torque, and takeoff distance are usually requested by the pilot from either an EFB or the FMS depending on setup. This request goes to a third party company, like Aerodata, in most situations. The speeds are then delivered after final bag and passenger count is submitted. Depending on the aircraft, takeoff torque is then set into the FMS, and the pilot flying just pushes the throttles into a rating detent. There are a few aircraft where the pilot monitoring has to fine tune the throttles after the PF pushes them up. The one I fly you request numbers through an EFB, set Vspeeds on the PFD and then just push to rating detent on the takeoff. The Engine control computer will limit the torque to a max of 98% but uses density altitude information to set the torque max by itself.
I’m just stopping by to thank you for your videos. Real Engineering and Wendover are the coolest channels on CZcams.
The problem with circular runways is the weather? That's why the plane can always be facing the wind? There are bigger problems than that in the concept, but not that one.
The problem is that you will always have a force acting sideways on the aircraft due to the slope and curvature of the runway. Increases airframe stress and probably accidents too
@@asdfasdgfasd I feel like another issue is getting the glide slope just right, if you are slightly too low, you have got to go around and if you are too high you have got to start circling with the runway.
@@asdfasdgfasd Actually, you can remove ALL of the sideways stress with proper banking. What you cannot do is remove the effects of the wind.
[5] how does it make sense😂? Even though they are switching runways but the direction is still the same as before as planes as still taking off from the west and landing from the east
So residents have relief from the noise. A plan is much louder when taking off since it's engines are throttling up. Engines are quieter as it lands since it is throttling doen
Well if you’d listen to the fuckin video you idiot he explains it literally right after
Cool video! I always think about this when I travel!
How can someone not find this interesting? This is awesome and so interesting
