    Automatic Continuous Thrust Control for Supersonic Transport Takeoff Noise Reduction
    Voet, Laurens J. A. ;
    Prashanth, Prakash
    2024-02-01 | PDF
    Advanced takeoff trajectories are proposed for supersonic transport noise reduction by capitalizing on excess engine thrust and improved aerodynamic efficiency at higher takeoff speeds. These novel trajectories use i) automatic continuous control of thrust, ii) increased takeoff speed, and iii) reduced cut-back altitude, compared to conventional pi ...
  • Global Impacts of Aviation on Air Quality Evaluated at High Resolution
    Global Impacts of Aviation on Air Quality Evaluated at High Resolution
    Eastham, Sebastian D ;
    Chossière, Guillaume P
    2024-02-01 | PDF
    Aviation emissions cause global changes in air quality which have been estimated to result in ~58 000 premature mortalities per year, but this number varies by an order of magnitude between studies. The causes of this uncertainty include differences in the assessment of ozone exposure impacts and in how air quality changes are simulated, as well as ...

  • Adapting the FAAHFSTD010A Standard Color Palette to Daytime Illumination
    Adapting the FAA-HF-STD-010A Standard Color Palette to Daytime Illumination
    Post, David L. ;
    Racine, Nicole
    2024-02-01 | PDF
    This project demonstrated that the color palette specified in FAA-HF-STD-010A (2020) can be used unaltered in air traffic control (ATC) towers during bright daytime conditions. The FAA palette introduced standard colors for coding ATC displays. It was developed to accommodate controllers who have mild-to-moderate color-vision deficiencies without c ...
  • PostSmall Flame Forensic Analysis of Aerospace Composites
    Post-Small Flame Forensic Analysis of Aerospace Composites
    Madabhushi, Abhijith ;
    Boushab, Dounia
    2024-01-01 | PDF
    Fire can dramatically alter the exposed surfaces of composite aircraft structures in ways that inhibit forensic analysis. The char, soot, and several other fire by-products often mask relevant aspects of the structural damage morphology, impeding identification of the underlying failure mechanisms of composite materials. In this report, the effects ...
  • Human Factors Evaluation of Large Displays in the Air Traffic Control Environment
