... After the National Research Council published the Decadal Survey of Civil Aeronautics, the National S ­ cience and Technology Council released the National Aeronautics Research and Development Policy and the more detailed National Plan. As shown in Table C-1, there is excellent correlation between the strategic objectives of the Decadal Survey and the key principles of the National Policy and the National Plan.

... 3. Support to the space program is not included as a principle of the National Policy, and the National Plan includes no R&D goals or objectives related to space except with regard to the demonstration of sustained, controlled hypersonic flight in support of national defense and homeland security (including space launch applications)

... In other words, the priorities of the 89 R&T challenges from the Decadal Survey of Civil Aeronautics were recalculated using the following weightings: Weighting Strategic Objective 1.0 Increase capacity 1.0 Improve safety and reliability 0.5 Increase efficiency and performance 0.5 Reduce energy consumption and environmental impact 1.0 Take advantage of synergies with national and homeland security 0.5 Support the space program Using this different weighting scheme, only four R&T challenges not previously ranked among the top 51 moved into the top 51. Those challenges are as follows: • A12.

... The Hypersonics Project does not address turbulence modeling for highly cooled walls. A14  Efficient control authority of advanced configurations to permit robust operations at hypersonic speeds and for access-to-space vehicles SFW SRW Supersonics Hypersonics Airportal Airspace IVHM IIFD IRAC Aging A/C        black         This R&T challenge has the following milestones: • Develop techniques to accurately predict flow-control authority in shock-dominated flows and in transitional flows.

... • Specify corrective actions appropriate for manned and unmanned aircraft in response to unplanned deviations detected by a flight monitoring system. The Integrated Intelligent Flight Deck Project is supporting substantial research related to manned aircraft, but it is not dealing with unmanned aircraft.
