To mitigate aircraft and airport noise

Challenge/Domain
Challenge: 
Protecting the environment and the energy supply
Domain category: 
Knowledge
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
Capability
Capability: 
Solutions for management of Noise Impact (MNI)
Sub capability: 
Metrics
R&I needs: 
- Number of Events Above # limit vs LDEN - Annoyance per flight (exposure x population) - Index for noise sharing
Achievements
2020: 
Improved, well accepted metrics providing other information than the acoustic energy, relating with key characteristics of a noise event are available to express current situations and help optimise environmentally aircraft and operations. The emergence of such metrics will also support efforts aimed at improved annoyance models and noise sharing options. Light Aviation specificities have been considered.
2035: 
Improved, well accepted metrics providing other information than the acoustic energy, relating with key characteristics of a noise event are available to express current situations and help optimise environmentally aircraft and operations. The emergence of such metrics will also support efforts aimed at improved annoyance models and noise sharing options. Light Aviation specificities have been considered.
Key Performance Indicator: 
No people impacted outside airport boundaries + TBD % improvement on LUP Implementation Progress Indicator
