    2010-11-01 | PDF
    Data Communication (Data Comm) is one of the key enablers required for the implementation of the Next Generation Air Transportation System (NextGen) Plan. NextGen addresses increasing air traffic levels and complexity for 2015 and beyond (Joint Planning and Development Office, 2007). We present the experimental evaluation of Data Comm between en ro ...
  • The AIRWOLF Tool To Support En Route Controller Weather Advisories
    The AIRWOLF Tool To Support En Route Controller Weather Advisories
    Ahlstrom, Ulf ;
    DiRico, John T
    2010-10-01 | PDF
    In current en route operations, controllers integrate weather information and traffic data manually while providing advisories to pilots. Previously, we developed a weather support tool called Automatic Identification of Risky Weather Objects in Line of Flight (AIRWOLF) that (a) detects conflicts between aircraft and hazardous weather, (b) alerts t ...
  • Moving Toward An Air Traffic Control Display Standard Creating A Standardized Target Symbology for Terminal Situation Displays
    Moving Toward An Air Traffic Control Display Standard: Creating A Standardized Target Symbology for Terminal Situation Displays
    Friedman-Berg, Ferne ;
    Allendoerfer, Kenneth
    2010-08-01 | PDF
    In this study, we applied human factors best practices to the design of an enhanced target symbol set for terminal displays. To design new symbols, we first identified types of information that would be most operationally useful. We selected four types of information that would provide the greatest operational benefits and tactical support for the ...
  • Flammability Test of AlcoholBased Hand Sanitizer
    Flammability Test of Alcohol-Based Hand Sanitizer
    Cavage, William M.
    2010-08-01 | PDF
    Some concerns have been raised about the flammability characteristics of personal hand sanitizer, which is presently being used in lavatories on many commercial airlines to mitigate the spread of the H1N1 virus. Personal hand sanitizer is a fluid, which is generally composed of approximately 60% ethyl alcohol by volume, and comes in two primary for ...

  • Evaluation of RetroReflective Beads to Increase Airport Surface Marking Conspicuity
    Evaluation of Retro-Reflective Beads to Increase Airport Surface Marking Conspicuity
    Previti, Anthony J. ;
    Gallagher, Donald W.
    2010-05-01 | PDF
    Manufacturers have postulated that retro-reflective beads that have a higher index of refraction increase the conspicuity of paint markings and, thus, would aid in the prevention of runway incursions. The purpose of this project was to determine the adequacy of various types of retro-reflective beads that are used to increase the conspicuity of pai ...
