The United States has a mix of runway types, while in the Middle East, the biggest hub Dubai uses “multiple layers of asphalt,” according to a Dubai Airports video on a recent runway rehabilitation project. The surface materials used depend on the climate and local conditions as well as other factors such as cost.Ĭoncrete is better than asphalt at withstanding extreme heat, though it is also more expensive and not as suitable in areas prone to ground settlement problems, Greg White, director of the Airport Pavement Research Program at Australia’s University of the Sunshine Coast, said this week. How Do Other Airports Cope With Extreme Heat? The airport said in the medium term it would need to ensure all airfield resurfacing projects considered the impact of increasing temperatures. Luton’s climate change adaptation report released in November 2021 warned one of the key risks was high temperatures causing infrastructure damage or impacting operations. Runways are typically resurfaced every 10 to 15 years.Įxperts say the airport, one of Britain’s busiest and used by budget airlines including Ryanair and EasyJet, may be more vulnerable to heat because it is at a higher elevation than the others surrounding the capital: Heathrow, Gatwick and Stansted. The spokesperson did not comment on questions about the timing of the runway’s resurfacing, the type of asphalt used or any possible changes to the material. “We continue to evaluate all options regarding the ongoing maintenance and long-term resilience of all of our infrastructure.” It is built to the same specification as others in Britain, meeting industry safety standards and regulations, the spokesperson said.

The Luton runway was closed for nearly two hours on Monday, prompting airlines to delay or divert flights as temperatures rose above 37 degrees Celsius (98.6 Fahrenheit), adding to industry headaches in what has been a chaotic summer travel season in Europe.Ī long-standing patch repair to a small section of the runway – the equivalent of 0.2% of the entire surface area – became so hot that it de-bonded and began to lift, a spokesperson for the airport said on Friday, adding it was repaired within two hours. Note: Please don't pretend your issue is more severe than it is when describing it.The temporary disruption at London’s Luton Airport on Monday when soaring temperatures caused a small section of the asphalt to lift is an example of the challenges airports face in making their infrastructure resilient to climate change, experts say.īelow is an explanation of how global airports are coping with extreme heat and what may be needed to prevent future interruption from further heatwaves.

However, if you submit a P5 and we change our code as a result of your submission, it will be bumped to a P4, and paid out accordingly. On the other hand, P5s are considered "recommended practices", and we intentionally don't follow all recommendations. P1s are scary, and we pay the maximum for those. We classify all submissions based on Bugcrowds Vulnerability Taxonomy.
The objective is to discover vulnerabilities in our web application and API. (Actually, we hope you can't find any of this, but you know what we mean.) It's not an invitation to be a bad person.
This program is an invitation to test our systems. Don't try to break into our physical offices or do anything illegal. We'll get into more examples later, but that means: Hack your own accounts, not someone else's accounts.
