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.
