At ground speeds above 20 knots during a typical takeoff roll, most jet airliners transition from steering the nose-wheel with the hand-operated tiller, which produces up to a 20 degree range of deflection from a straight line, to steering with the rudder pedals, whose own range of wheel deflection is limited to just 6 degrees to either side of a straight line. The tiller is ONLY used during taxi to, and from, the runway of arrival or takeoff, while the rudder is used exclusively at all ground speeds above 20 knots, with typical rudder inputs being very subtle, and limited to the small corrections required to track the DEAD STRAIGHT runway center-line as the aircraft thunders down the runway under full takeoff throttle settings. The concept of a circular runway will NEVER work in practice, because of the major steering inputs that would be required to keep the aircraft in a constant turn around that circular path. As speed builds during takeoff, any deviation from a dead straight line would cause the aircraft to become unstable due to tangential forces that would arise, resulting in the bird simply veering off the circular runway into an uncontrollable crash. With all this in mind, I therefore join the Almighty Baale of San Fernando Valley, Egun Mogaji, in reaching for my bullchit whistle in order to raise a timely alarm to the inherent falsehood of this tall tale about circular airport runways. 2 Likes 1 Share

Hmmm. This looks more of a design, than actual. @ MagnaB. The entry and exit of passengers to the airport will be underground 1 Like

So not feasible a plan. Will the passengers have to cross the circumference of the airway before they can board a flight or what will convey them to the airport without having to cross the airway. Provide me an answer to this or i'l say its a short sighted plan. 1 Like |

MagnaB: Passenger movement is NOT an issue here. In airports like Chicago Ohare, where I transit through quite frequently, passengers move with ease from one terminal to another, on moving walkways routed through underground tunnels that pass beneath the runways and taxiways. The issue with a circular runway is that an aircraft at landing or takeoff speeds MUST maintain a dead straight line, with NO curvature at all. This straight line is the only way to maintain stability when a plane is zipping along at speeds in excess of 100 knots before takeoff or after landing. 5 Likes |

Just wondering how an aircraft can land or takeoff on a circular runway. There is high speed before takeoff and after landing, are aeroplanes going to be rebuilt like tubes? |
Re: Circular Runway Allows Planes To Take Off And Land In All Directions by obinna222: 7:58am On Apr 07, 2017 |
Nice idea, but a circular runway isn't the safest. in extreme weather condition like snow or similar condition , a circular runway might not be the best choice for landing or taking off. I also don't believe it's ideal for a high speed take off and emergency landing. |

One major issue would be the amount of "float". Although airplanes target touching down right at the end of the runway, that doesn't always happen. Sometimes due to excess speed, gusty winds, or a misjudged flair, the plane will float a distance down the runway before actually touching down. During this time, the plane's nose may be high, and visibility of the runway is limited. Because the runway is straight, its no problem. But suggesting that a pilot navigate a curved runway while floating further than anticipated is just nuts. If they don't turn enough, they end up outside the curve of the runway. If they turn too much, they end up inside the curve. Either way, if they over correct at low altitude and airspeed, the chance of a catastrophic crash is unacceptably high. #copied 4 Likes |

Just thinking out loud here. If the airport is round and the planes are to land at the surface area of the airport thus dividing the terminals from the general public, how are they gonna get to the terminals? Underground roads cost a lot of money and thus maki this airport much more expensive than your average airport. |

Mojibola: Very correct indeed. Besides, the approach and landing guidance support system for this has not been invented yet. You have to wonder whether this concept came from an aeronautical engineer or an architect! It's just too futuristic. But, let's watch and see. In technology, never say never. |

Clearly, whoever is proposing this circular runway didnt and haven't considered alot of factors before publicizing this great idea. I noticed how he made account for skidding since its gonna be a BANKED circular runway, but that only covers for takeoffs. What about landing?! Are planes supposed to land on a banked runway?! This clearly is a disaster because planes need their landing terrain well leveled and balanced. The proposal has alot of advantages than disadvantages, but in this case, one disadvantage is more important than a whole lot of advantages because this matter holds alot of lives. 1 Like |

My only question is wouldn't this increase your takeoff run and takeoff distance as you have to turn while accelerating as against a straight and level acceleration. 1 Like |
