Networked Next Generation Air Transportation System (NextGen) opened the gate to digital National Airspace System (NAS) in cyberspace. Air traffic improvements from NextGen system, accompanied by the risk of long-standing cyberattack issue in information technology industry became an increasingly challenging matter to the aviation community and Air Traffic Management (ATM), as cybersecurity challenges in the NextGen system could affect NextGen's principle assurance of safety and security in air transportation. The technological shift of NAS infrastructure from traditional radar-based systems to networking system of systems leads to a review, revision and redefinition of current policies, standards regelations, cultures and norm to reflect and mitigate new risks. Through analysing reports, regulations, standards, practices, recommendations from government and industry, the researchers analyse security impacts to NextGen; the risk of a cybersecurity incidents; and regulations to identify most effective and efficient control measures over information systems in ATM, and direction to further research.
Diversity within the science, technology, engineering, and mathematics (STEM) fields has historically lagged behind that which is found in other vocational paths. Aviation has also suffered poor diversity with virtually no participation among professional pilots. With both the literature specifying the benefits of diversity in the aviation workplace and potential shortages of pilots looming, it is in the interest of aerospace stakeholders to have access to the most comprehensively diverse employee pool possible. The purpose of this research was to evaluate the trends in participation by minorities who completed professional pilot education programs in the United States. Data concerning the number of students who completed degrees at the associate's, bachelor's, and master's levels were collected via the Integrated Postsecondary Education Data System (IPEDS). Participation rates were compared to those found within the aviation industry. In general, the participation rates by non-White minorities in collegiate aviation (27.3%) exceeds that reported in the professional pilot vocation (18.4%). Detailed trends over the past 10 years were evaluated. Between 2004 and 2014, minority (including women) participation increased from 17.1% to 22.2%, which was deemed to be statistically significant (z 5 3.7, p , 0.001). The greatest gains were exhibited among Hispanics (p , 0.001), specifically Hispanic men (p , 0.001), with marginal gains by Asians (p 5 0.06). Decreases were noted in Native American participation (p 5 0.03) as well as among women, albeit not significantly (p 5 0.31). When extending the analysis back another seven years, minority (including women) participation showed significant change from 1997 (16.5%) to 2014 (22.2%), z 5 3.7, p , 0.001. Minority participation in professional pilot education has shown steady gains over the past two decades; however, it appears that this trend is leveling, especially among women. Further study is recommended with particular interest in promotion and recruitment of a diverse aviation student population.
By 2020 all aircraft in United States airspace must use ADS-B (Automatic Dependent Surveillance-Broadcast) Out. This is a key component of the Next Generation (NextGen) Air Transportation System, which marks the first time all aircraft will be tracked continuously using satellites instead of ground-based radar. Standard Terminal Automation Replacement System (STARS) in the Terminal Radar Approach Control (TRACON) is a primary NextGen upgrade where digitized automation/information surrounds STARS controllers while controlling aircraft. Applying the SHELL model, the authors analyze human factors changes affecting TRACON controllers from pre-STARS technology through NextGen technologies on performance. Results of an informal survey of STARS controllers assessed cognitive processing issues and indicates the greatest concern is with movements to view other displays and added time to re-engage STARS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
