Our vision:
To enhance the benefits of air transport, while removing or minimising any impacts on the local and global environment
Our role:
To develop practical and policy solutions for cleaner, quieter, smarter flying
Our Approach:
We engage regularly with stakeholders to communicate our work and to understand their priorities
We aim to be a trusted and credible source of information
We focus on the UK, however our work takes place in a global context

4. SA Noise Road-Map

5. Complexity of noise annoyance
Triggers of annoyance to aircraft noise are becoming more complex and variable
Industry / community joint work to develop noise management options

6. 10 years of evolving aerospace manufacturing
470 new aircraft introduced by UK airlines
359 more aircraft on order with UK airlines

7. Reduced aircraft noise
Jet aircraft in service today are typically dB quieter than those of the 1960’s
A new Chapter 14, cumulative 7 EPNdB below Chapter 4, was agreed by ICAO for application to new aircraft designs after 2017, and 2020 for smaller types
Looking forward, research goals include reducing the perceived noise emission of flying aircraft by 65% (15dB) in 2050 relative to a typical new aircraft in 2000

8. Noise Road-Map – Operational Improvements
Operational Improvements relate to how and where aircraft operate
Operational improvements give the opportunity to influence noise both close in to the airport and further away
There is scope to increase the use of noise sharing techniques which may reduce community annoyance with noise
Operational improvements can be expected to offer noise reductions of between 1 and 5 decibels (SEL) by 2030 against a 2010 baseline
The exact noise improvement will vary for different communities depending on the current noise exposure and local scope for adopting new techniques

10. UK aircraft noise performance

11. Other UK Airspace trials – Stansted Airport
Worked with community groups
7 year process
Change supported by Consultative Committee Environmental Issues Group

12. Stansted Airport RNP Trial - Results
85% fewer people overflown
Before
After

13. Luton Airport RNAV1 Airspace trials
Area Navigation (RNAV1) technology for departing flights leaving the airport along the Match/Detling flight routes used during westerly operations
Trials carried out from March to June 2013 found that the introduction of RNAV technology reduced the number of people over flown by 79% and will lead to annual savings of 885 tonnes of CO2
New route launched August 2015

14. Luton Airport – Community Reaction
Neil MacArthur, of local community group Harpenden Sky, said: “On behalf of the HarpendenSky.com membership, and those other Harpenden west, south and central residents affected by Luton departing aircraft, we want to sincerely thank London Luton Airport for the understanding and effort that has been put into RNAV1 as a resolution of this issue.”

15. Future SA noise work Support airspace change – sharing best practice
Developing best practice land use planning guidance around airport
Improving how the industry works with communities to develop noise management solutions
Continuing to deliver on noise reductions at source and through operational improvements
Continue to provide data to show how the industry is doing on reducing noise

16. Thank you! Any questions?
