The Next Step - An Airport Perspective

• Gary Stowell
• Noise Abatement Manager
• San Jose International Airport

2
Where to go from here?

• A perspective on the technology needed to
  address the impact of aviation on the environment

3
Ultimate Goals

• Eliminate the need for restrictions on airports,
  airspace, and aircraft operations
• Establish and maintain community acceptance for
  airport operations, and growth of the air
  transportation system

4
A Proposed Strategy

• How can we increase capacity and achieve a
  Net Environmental Gain?

5
How do we get there from here?ECoA Workshops
Focus

• Workshop One Q3 - Must the growth of aviation
  lead to increased environmental impacts?
• What can we do?

6
Back to Basics

• Source
• Path
• Receiver

7
Source

• Quieter technology
• Quiet and efficient operating procedures
  (vertical?)
• Longer distance capabilities

8
Path

• Better understanding of weather influences on
  noise propagation
• Active noise cancellation
• Variable frequency noise cancellation

9
Receiver

• Improved land use compatibility
• Updated guidelines
• Updated policies that local jurisdictions can
  adopt

10
Additional Goals

• Provide for growth - intelligent land use
  decisions
• Avoid litigation
• Gain local support

11
How Can NASA Help?

• Technology
• Accurate prediction
• Technical support for regulations
• Improved airport infrastructure

12
Obstacles

• Case law
• Possible damages
• Funding
• Regulatory environment

13
How do we get the best Bang for the Buck with
existing technology

• Identify existing technologies
• Promote their usage
• Create incentives
• Remove roadblocks

14
How can we maximize the benefit of existing
technology?

• Improved aircraft technology
• Improved operational procedures and ATM tools
• Improve existing tools, i.e., monitoring systems
  and analysis software

15
With NASAs help we can generate a

• WIN - for airports
• WIN - for operators
• and
• WIN - for the community
