To mitigate aircraft and airport noise

Challenge/Domain
Challenge: 
Protecting the environment and the energy supply
Domain category: 
Technology
Enabler
Enabler: 
To mitigate aircraft and airport noise
Cluster of enablers: 
Improving the airport towards the future through a global approach The airport is a crucial infrastructure enabling the delivery of an air transport service as expected by society in 2050. The main local environmental impacts of air transport operations regard noise, natural resources and local air quality, which can affect health of people and eco systems. Mitigating these impacts is crucial to get acceptance of airports by citizens. The challenge will be to make the numerous stakeholders to work together towards solutions
