Gary Stowell Noise Abatement Manager San Jose International Airport The Next Step - An Airport Perspective

Where to go from here? A perspective on the technology needed to address the impact of aviation on the environment

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

A Proposed Strategy How can we increase capacity and achieve a “Net Environmental Gain?”

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?

Back to Basics:  Source  Path  Receiver

Source:  Quieter technology  Quiet and efficient operating procedures (vertical?)  Longer distance capabilities

Path:  Better understanding of weather influences on noise propagation  Active noise cancellation  Variable frequency noise cancellation

Receiver:  Improved land use compatibility  Updated guidelines  Updated policies that local jurisdictions can adopt

Additional Goals  Provide for growth - intelligent land use decisions  Avoid litigation  Gain local support

How Can NASA Help?  Technology  Accurate prediction  Technical support for regulations  Improved airport infrastructure

Obstacles  Case law  Possible damages  Funding  Regulatory environment

How do we get the best “Bang for the Buck” with existing technology  Identify existing technologies  Promote their usage  Create incentives  Remove roadblocks

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

With NASA’s help we can generate a: WIN - for airports WIN - for operators and WIN - for the community
