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: Props go to him for the clever technique.

@Will Harris runway 26?

Had a check of runway direction, and they do seem to generally be aligned with prevailing wind direction... Beijing Capital Airport, Dubai, and Tokyo Haneda are three exceptions where the runways aren't aligned east west while still being in the northern hemisphere

Maybe stupid but since take off and landing are the most dangerous and fuel consumption moments, what about an arm or a launcher to litteraly take the plane ?

That circular run ray really scares me, the fact someone would come up with that idea means they have no knowledge of aircraft. And as a pilot myself that’d be a nightmare even in my bonanza

This video is incorrectly named. It does not really address the perfect runway. It is focused on Heathrow Airport having outgrown its useful life in its current location. The airport closer to the "perfect runway" would be something like Dallas-Fort Worth, but there's no way to fit that airport anywhere near London. No disrespect intended to London - it's just got no space to put a new airport.

The best runway in the world is KSP's. You cannot land anything on it. Not because it's too short or surrounded with mountains... No, just because the physics make planes almost impossible to control !

Nazar Dmytrovskiy (1 month ago)
I agree with you, but you forgot one thing. Performance factors. If you have wet runway you have to multiply distances by 1.15 for landing (LDA) And what is more important is the safety margins. If you fly with a plane where it is needed 1000 meters to stop and the runway available is 1300 meters you are NOT allowed to land, in this case minimum RWY distance for you to legally land must be 1420 meters. Same with T/O but you have to multiply by 1.25.

Man you missed out on the Adolfo Suarez Madrid Barajas Airport, it runs quad runwas of wich to main ones, 4500m each and for these one secondary runway 3500m, size-wise it is bigger than the 2nd largest you named... And its Ms of runway per passenger isn't that different 0.00012093379m/pas. against 0.00012059117m/pas. it isn't that different and I beleive "size does matter." I'd be pleased to know you at least considered the fact and didn't just go on google and type "biggest airports annual traffic" and that you used the 2017 results as the 2018 are preliminary and the 2019 aren't even out. Signed, a preocupied Subscriber. Thenk You P.D. PLs respond I am a bit worried... P.P.D. I have said Madrid barajas airport because I live in spain and noticed the Beijing airport isn't thet big, but I am sure there are others...

Heathrow was originally built with 6 runways of equal length, laid out in the star of David design. This was due to all aircraft using it being prop driven. whilst 27R &27L have been extended to cope with jets, the original runways can be determined as some remain as taxiway. Before it was a civilian airport it was a large grassed field commandeered for WW2 use. The original design of the star of david layout ensured all wind conditions could be coped with.

You kept showing recent footage from DCA, but never referenced it in the examples used.... it is also a very unique airport with slot controls, limited radius served, proximity to highly sensitive ARSA, and lots of political aspects... if I can ask, why did it not show up in your discussion ? Oh, and I've worked there for 25 years !

Balanced field length is when the accelerate stop and accelerate go distances are the same distance ... not exactly what is said in the video (or maybe I misunderstood the explanation in the video). Otherwise I love this channel and the video is great.

The engineers working on airport design are horrible. Make a hexagram landing strip aligned to the prevailing winds of the location. This gives you the best possible take off and landing pads in all conditions, temperatures and wind conditions. It's not rocket science. Idiots.

Strange that you didnt mention anything about radars, in video which is about perfect airport. Radars are one of the most important things in the subject. One of the most important ones to have, especially on busy airport is ground and waether radars. So you can see where the planes are even in heavy fog or other extreme weather. While weather radar are to detect those crosswinds you mentioned, which are very important to detect. In order to takeoff or land safely. Other important radars are ESR (En Route Surveillane Radar), TAR (Terminal Area Radar) and PAR (Precision Approach Radar). Also, if i recall correctly you didnt mention anything about calculating take off weight. Which also affect on V1 speed. Calculating that wrong can also lead to crash as have happened few times. And too far away locationed weather radar was the reason to one close call crash where crosswind was way more powerful which the plane were controllable. Missing an ground radar was one reason what led to deadliest aviation crash in history. Which also was affected by misscommunication and missunderstandings aswell.

Take a look at Kingsford Smith International in Sydney, Australia for an example. 3 things about it, 1. The airport must close Entirely from 11pm - 6am due to the position of the airport being so close to suburbs of Sydney. The only exception is emergency aircraft, otherwise, the airport is closed to All aviation all night long. 2. There is only 1 runway (out of 3) that is long enough for the largest of aircrafts to land on it. 3. There is no possible way to expand the airport due to its position being so close to residential areas. There was a proposed idea to build a second airport opposite the current one but it got scrapped a while ago.

​@Plainjupiter724 Ok, I just researched about the launching mechanism and you're right! However, if you want to say each airport in the world wants a catapulting system similar to carriers, that's nearly millions or even billions of dollars for a single airport!

I think you dismissed circular runways too quickly. On the contrary, air traffic control could choose any segment of the circle and essentially eliminate crosswinds. Also, runway length and all associated calculations could be dismissed.
clearskyxx (1 month ago)
A circular runway is a very stupid idea. Landing and taking off would be very difficult, due to constant yawing of the plane, you would be landing in a turn. There are numerous other factors, that make such a design just useless and impractical, other pilots have already commented on that.

What if runways were circular, allowing landing in any direction? It wouldn't be as land-efficient though I guess.
