sioned that these incremental improvements will provide incrementally increased capacity at airports where implemented.


Recommendation 2-1. Federal wake turbulence research should have the following characteristics:

  • The FAA should be the lead agency for defining requirements for wake turbulence research.

  • The FAA should manage and fund capacity-focused wake turbulence research using academic, industry, and other government partners.

  • The FAA should appoint a strong and motivated leader to integrate and coordinate research across agencies, define priorities, and represent wake vortex research to the JPDO and other agencies.

  • Research should be sustained over the short, medium, and long term.

  • Resource allocations across functional lines of involved agencies should be coordinated among all agencies involved in this work.

Finding 2-3. The change in aeronautics research priorities at NASA has led to a gap in the wake turbulence program as previously envisioned.


Finding 2-4. Present federal investment does not place sufficient priority on wake turbulence research to achieve the results called for by the NextGen goals.


Finding 2-5. NASA expertise is well-aligned to conducting medium- to long-term fundamental research, including wake vortex modeling and wake vortex alleviation work, while the FAA does not currently have such expertise.


Recommendation 2-2. Because of its expertise, NASA should continue to conduct medium- to long-term fundamental research, including wake vortex modeling and wake vortex alleviation work at a level of effort sufficient to achieve NextGen goals.


Recommendation 2-3. Operators and controllers should be included in the process of designing, implementing, and evaluating wake turbulence-related changes to the air transportation system.


Recommendation 2-4. JPDO should recommend to the FAA detailed wake vortex research efforts needed to support NextGen.
