Could CIRCULAR runways take off? Aerospace tests show circle designs would increase capacity, allow for simultaneous landings and take-offs and remove the risk of crosswinds
- The runway would be built as a 3.5km wide circle around an airport terminal
- Aircraft can avoid risky crosswinds by landing in any direction, says scientist
- It would allow for a high volume of traffic as several takeoffs and landings could take place simultaneously
Circular runways could revolutionise commercial aviation while increasing the capacity of airports by 2050, according to a leading Dutch scientist.
Built as a 3.5km wide circle around an airport terminal, the runway would allow for a high volume of traffic as several takeoffs and landings could take place simultaneously.
The design is safer than conventional airports because aircraft can avoid dangerous crosswinds by landing in any direction, according to Henk Hesselink, an engineer at Royal Netherlands Aerospace Centre (NLR).

The landing aircraft can also be routed away from residential areas to reduce noise pollution because they are not dependent on a standard approach path.
The endless runway design has a slight incline and curve as it surrounds the entire airport.
‘We need to rethink the way we are dealing with airports, with capacity, with the environment,’ Hesselink told Mashable.
‘We are looking for a solution where aircraft can take off and land under any weather conditions.’
A singular circular runway could handle the traffic of four conventional runways and takes up less space, according to Hesselink.

There have already been some trials on a circular track with fighter pilots who have landed there.
‘These pilots reported in the beginning it was a bit strange but after two or three trials they reported it is very well possible,’ Hesselink added.
The radical circular runway is part of an effort to increase capacity at airports amid increasing levels of traffic. Scientists believe mobility will be stressed in the coming decades and new technology will be necessary.
‘We can keep on optimizing the system, but at a certain moment, small steps don’t work anymore and we really need a new idea to cope with the anticipated traffic,’ said Hesselink.
The circular design is part of ‘The Endless Runway‘ project, led by a team of Dutch scientists from the NLR.
The work has been carried with partners in The Netherlands, Germany, Spain and Poland.
