Communicating social responsibilities through CSR reports: Comparative study of top European and Asia-Pacific airlines. PLoS One 2021; 16:e0258687. [PMID: 34648599 PMCID: PMC8516251 DOI: 10.1371/journal.pone.0258687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 10/03/2021] [Indexed: 11/19/2022] Open
Abstract
Recently the outbreak of major social incidents has put the airline industry in the forefront of the debate. However, studies related to the social dimension of the Global Reporting Initiative (GRI) Standards in aviation are limited. To fill the gap, this study explored the social themes of corporate social responsibility (CSR) practices between European and Asia-Pacific based airlines. Quantitative content analysis is employed for comparing the social topics in CSR reports of 20 top airlines from Asia-Pacific and European regions over a 3-year period. It concludes that both regions focused more on labor management relations and supplier assessment. The Asia-Pacific airlines have placed special attention to adequacy of social information provided in their CSR reports while the European airlines kept reporting with a comprehensive method. This paper informs both academics and practitioners on the differences of the social dimension of sustainability between the European and Asia-Pacific aviation industry.

Technological innovation of Continuous Glucose Monitoring (CGM) as a tool for commercial aviation pilots with insulin-treated diabetes and stakeholders/regulators: A new chance to improve the directives? Diabetes Res Clin Pract 2021; 172:108638. [PMID: 33358969 DOI: 10.1016/j.diabres.2020.108638] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 12/12/2020] [Accepted: 12/16/2020] [Indexed: 11/30/2022]
Abstract
Civil aviation pilots who develop insulin-treated diabetes and want to renew a Commercial Pilot License (CPL) represent a medical, social and regulatory problem. This depends on justified concerns about hypoglycemia, the most threatening event for people who carry out jobs requiring a high level of concentration and reliability. This negatively affects social and working aspects of pilots' lives, who have a high profile and a high-cost professional qualification. It could be possible now to revise this attitude thanks to the availability of Continuous Glucose Monitoring (CGM) devices. CGM clearly showed to prevent hypoglycemic events in insulin-treated diabetic patients by allowing strict monitoring and trend prediction of glucose levels. By systematizing available data on such devices and present regulations in CPL issuance worldwide, our review can be used as handy tool for a fruitful discussion among the scientific community, national and international civil aviation regulators, stakeholders and pilots, aimed at evaluating the evidence-based opportunity to revise CPL issuance criteria for insulin-treated diabetic pilots. For the above-mentioned reasons, there are, among the regulatory administrations of Civil Aviation around the globe, several different approaches and limitations set for the subjects with insulin-treated diabetes who want to obtain, or renew, a CPL.

Cabin crew health and fitness-to-fly: Opportunities for re-evaluation amid COVID-19. Travel Med Infect Dis 2021; 40:101973. [PMID: 33450405 DOI: 10.1016/j.tmaid.2021.101973] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 01/05/2021] [Accepted: 01/06/2021] [Indexed: 11/18/2022]
Abstract
Aircrew fitness-to-fly is among the elements that make aviation the safest form of long-distance transport. The health of cabin crew is a crucial determinant in carrying out safety-related duties. 'Fitness-to-fly' is associated with defined workplace conditions, for which airlines have a legal duty to ensure fitness for employment. We explored the literature on fitness-to-fly to obtain a pragmatic assessment of the challenges for aeromedical examinations. Regulations promulgated by aviation regulatory authorities and airline-internal policies have similar status and meaning, yet there is no harmonised approach internationally, and an inability to conform periodic medical assessments to actual operational fitness. The COVID-19 pandemic has highlighted the need to better understand fitness-to-fly criteria. Fitness-to-fly measures are mainly based on self-reported data and there is a need for a 'safety' factor for self-reports. Aeromedical evaluations should evolve from meeting medical standards to include pandemics as an element of the overall risk of aircraft operations. Re-evaluating criteria for fitness-to-fly assessment will further the goal of linking research to the actual needs of public health decisionmakers. If airlines are to resume operations at pre-pandemic levels, they must demonstrate to the public and public health agencies that fitness-to-fly assessment is appropriate and effective.

Monitoring of Low-Level Wind Shear by Ground-based 3D Lidar for Increased Flight Safety, Protection of Human Lives and Health. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16224584. [PMID: 31752438 PMCID: PMC6888573 DOI: 10.3390/ijerph16224584] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 11/15/2019] [Accepted: 11/16/2019] [Indexed: 11/29/2022]
Abstract
Low-level wind shear, i.e., sudden changes in wind speed and/or wind direction up to altitudes of 1600 ft (500 m) above-ground is a hazardous meteorological phenomenon in aviation. It may radically change the aerodynamic circumstances of the flight, particularly during landing and take-off and consequently, it may threaten human lives and the health of passengers, people at the airport and its surrounding areas. The Bratislava Airport, the site of this case study, is one of the few airports worldwide and the first in Central Europe that is equipped with a Doppler lidar system, a perspective remote sensing tool for detecting low-level wind shear. The main objective of this paper was to assess the weather events collected over a period of one year with the occurrences of low-level wind shear situations, such as vertical discontinuities in the wind field, frontal passages and gust fronts to increase the level of flight safety and protect human lives and health. The lidar data were processed by a computer algorithm with the main focus on potential wind shear alerts and microburst alerts, guided by the recommendations of the International Civil Aviation Organisation. In parallel, the selected weather events were analyzed by the nearby located meteorological radar to utilize the strengths of both approaches. Additionally, an evaluation of the lidar capability to scan dynamics of aerosol content above the airport is presented.

Abstract
INTRODUCTION: The value of aeromedical certification in reducing adverse medical outcomes is an especially important question for this era of increasing flight operations that do not require an FAA medical certificate. The study of this question has previously been thwarted by a lack of information about pilots when their medical certificates are not renewed.METHODS: We matched airmen in the FAA medical certification database to the U.S. Social Security Death Index to identify date of death for deceased pilots. Logistic regression models were used to explore associations of certification data with odds of death while holding a medical certificate and within 4 yr of expiration of a medical certificate.RESULTS: FAA aeromedical waivers were associated with 33% lower odds of death while holding a medical certificate and 35% increased odds of death within 4 yr after expiration of a medical certificate. Denial was associated with 21% increased odds of death in the next 4 yr. Only 13 of 47 medical conditions having significant associations were associated with increased odds of death during certification.DISCUSSION: We found that FAA aeromedical certification reduces the odds of death while holding a medical certificate compared to the 4 yr after certificate expiration. We believe this helps provide a positive answer to the question of whether medical certification reduces medically related events.Mills WD, Greenhaw RM.

Abstract
BACKGROUND: From a population-based perspective, reports in the peer-reviewed medical literature suggest an increase in the overall prevalence of asthma in recent decades. Applicants for military aviation training with a current or past history of asthma are generally excluded in the United Kingdom.METHODS: In order to assess the impact of the prevalence of asthma on the available pool of military service candidates, the authors collected data on annual live births between 1916 and 2016 as well as peer-reviewed publications that provided insight into asthma prevalence trends within the United Kingdom across the last century (covering birth-year population cohorts ranging from 1924 to 1995). Regression techniques were used to estimate the prevalence of individuals who could reasonably expect to be found unfit for military aviation service due to asthma-like conditions within the birth-year cohorts between 2001 and 2016.RESULTS: Between 1916 and 2016, the number of live births in the United Kingdom has averaged approximately 802,000 per year. The reported prevalence of asthma, based on the assimilated data points, ranged from 2.3 cases per 1000 individuals among the 1924 birth-year cohort, to 29.8 cases per 1000 individuals among the 1990 birth-year cohort.DISCUSSION: Based on the data and analysis presented above, asthma continues to constitute a significant public health issue in the United Kingdom. Military services must base risk mitigation decisions on accurate and precise diagnostic categorizations, and prudently balance the benefits of allowing affected individuals to participate in military service with the potential for mission degradation or compromise.Porter WD, Powell-Dunford N, Wilde GD, Bushby AJR.

Equal to or better than: The application of statistical non-inferiority to fatigue risk management. ACCIDENT; ANALYSIS AND PREVENTION 2019; 126:184-190. [PMID: 29428150 DOI: 10.1016/j.aap.2018.01.020] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2017] [Revised: 11/22/2017] [Accepted: 01/15/2018] [Indexed: 05/24/2023]
Abstract
In December 2014, the Federal Aviation Administration (FAA) completed a major revision of the rules and regulations governing flight and duty time in commercial aviation (Federal Aviation Regulation (FAR) Part 117). Scientists were included in the revision process and provided insights into sleep, sleep loss, the circadian rhythm, and their effects on performance that were incorporated into the new rule. If a planned flight was non-compliant with the regulation, for example if it exceeded flight and duty time limits, it could only be flown under an FAA-approved Fatigue Risk Management System (FRMS) as meeting an Alternative Method of Compliance (AMOC). One method that a flight could qualify as an AMOC is if it could be demonstrated empirically that it was as safe as or safer than a similar flight, designated the Safety Standard Operation (SSO), that was compliant with the regulation. In the present paper, we demonstrate the FRMS process using a comparison between a non-compliant AMOC flight from the US west coast to Australia and a compliant SSO flight from the US west coast to Taiwan. The AMOC was non-compliant because it exceeded the flight time limits in the prescriptive rule. Once a data collection exemption was granted by the FAA, both the outbound and inbound AMOC and SSO routes were studied on four Safety Performance Indicators (SPIs). The SPIs studied were inflight sleep, cognitive performance, self-reported fatigue, and self-reported sleepiness. These measures were made at top of descent (TOD), a critical phase of flight. The study was designed as a paired comparison. Forty volunteer pilots studied flew both the AMOC and the SSO flights for a total of 80 studied flights. Using statistical non-inferiority applied to the AMOC and SSO SPIs, we demonstrated, as required by the new rule, that the US-Australia AMOC flight was "as safe as, or safer than" the US-Taiwan SSO flight. In the context of FRMS, statistical non-inferiority is a concept and technique of great utility, straightforward in application, producing clear visual representations of the findings, and providing a direct answer to the question posed by the regulation - is the AMOC flight "as safe as, or safer than" the SSO.

Abstract
To develop and validate a classification of non-technical skills (NTS) in military aviation, a study was conducted, using data from real operations of F16 aircraft formations. Phase 1 developed a NTS classification based on the literature review (e.g. NOTECHS) and a workshop with pilots. The Non-TEChnical-MILitary-Skills (NOTEMILS) scheme was tested in Phase 2 in a series of Principal Component Analysis with data from After-Action-Review sessions (i.e. 900 records from a wide range of operations). The NTS were found to make a good prediction of Mission Essential Components (R2 > 0.80) above the effect of experience. Phase 3 undertook a reliability analysis where three raters assessed the NOTEMILS scheme with good results (i.e. all rwg > 0.80). To look into the consistency of classifications, another test indicated that, at least, two out of three raters were in agreement in over 70% of the assessed flight segments. Practitioner Summary: A classification scheme of Non-Technical Skills (NTS) was developed and tested for reliability in military aviation operations. The NTS scheme is a valuable tool for assessing individual and team skills of F-16 pilots in combat. It is noteworthy that the tool had a good capability of predicting Mission Essential Competencies.

Systematic assessment of intrinsic factors influencing visual attention performances in air traffic control via clustering algorithm and statistical inference. PLoS One 2018; 13:e0205334. [PMID: 30359377 PMCID: PMC6201895 DOI: 10.1371/journal.pone.0205334] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Accepted: 09/18/2018] [Indexed: 11/18/2022] Open
Abstract
The intrinsic factors (IF) influencing visual attention performance (VAP) might cause potential human errors, such as “error/mistake”, “forgetting” and “omission”. It is a key issue to develop a systematic assessment of IF in order to distinguish the levels of VAP. Motivated by the Stimulus-Response (S-R) model, we take an interactive cancellation test—Neuron Type Test (NTT)—to explore the IF and present the corresponding systematic assessment. The main contributions of this work include three elements: a) modeling the IF on account of attention span, attention stability, distribution-shift of attention with measurable parameters by combining the psychological and statistical concepts; b) proposing quantitative analysis methods for assessing the IF via its computational representation—intrinsic qualities (IQ)—in the sense of computational model; and c) clustering the IQ of air traffic control (ATC) students in the feature space of interest. The response sequences of participants collected with the NTT system are characterized by three parameters: Hurst exponent, normalized number of decisions (NNoD) and error rate of decisions (ERD). The K-means clustering is applied to partition the feature space constructed from practical data of VAP. For the distinguishable clusters, the statistical inference is utilized to refine the assessment of IF. Our comprehensive analysis shows that the IQ can be classified into four levels, i.e., excellent, good, moderate and unqualified, which has a potential application in selecting air traffic controllers subject to reducing the risk of the inadequacy of attention performances in aviation safety management.

Abstract
OBJECTIVE To better understand the external factors that influence the performance and decisions of aviators involved in Naval aviation mishaps. BACKGROUND Mishaps in complex activities, ranging from aviation to nuclear power operations, are often the result of interactions between multiple components within an organization. The Naval aviation mishap database contains relevant information, both in quantitative statistics and qualitative reports, that permits analysis of such interactions to identify how the working atmosphere influences aviator performance and judgment. METHOD Results from 95 severe Naval aviation mishaps that occurred from 2011 through 2016 were analyzed using Bayes' theorem probability formula. Then a content analysis was performed on a subset of relevant mishap reports. RESULTS Out of the 14 latent factors analyzed, the Bayes' application identified 6 that impacted specific aspects of aviator behavior during mishaps. Technological environment, misperceptions, and mental awareness impacted basic aviation skills. The remaining 3 factors were used to inform a content analysis of the contextual information within mishap reports. Teamwork failures were the result of plan continuation aggravated by diffused responsibility. Resource limitations and risk management deficiencies impacted judgments made by squadron commanders. CONCLUSION The application of Bayes' theorem to historical mishap data revealed the role of latent factors within Naval aviation mishaps. Teamwork failures were seen to be considerably damaging to both aviator skill and judgment. APPLICATION Both the methods and findings have direct application for organizations interested in understanding the relationships between external factors and human error. It presents real-world evidence to promote effective safety decisions.

Abstract
BACKGROUND The transition away from written documentation and analog methods has opened up the possibility of leveraging data science and analytic techniques to improve health care. In the implementation of data science techniques and methodologies, high-acuity patients in the ICU can particularly benefit. The Principles of Automation for Patient Safety in Intensive Care (PASPIC) framework draws on Billings's principles of human-centered aviation (HCA) automation and helps in identifying the advantages, pitfalls, and unintended consequences of automation in health care. THE FRAMEWORK AND ITS KEY CHARACTERISTICS Billings's HCA principles are based on the premise that human operators must remain "in command," so that they are continuously informed and actively involved in all aspects of system operations. In addition, automated systems need to be predictable, simple to train, to learn, and to operate, and must be able to monitor the human operators, and every intelligent system element must know the intent of other intelligent system elements. In applying Billings's HCA principles to the ICU setting, PAPSIC has three key characteristics: (1) integration and better interoperability, (2) multidimensional analysis, and (3) enhanced situation awareness. RECOMMENDATIONS PAPSIC suggests that health care professionals reduce overreliance on automation and implement "cooperative automation" and that vendors reduce mode errors and embrace interoperability. CONCLUSION Much can be learned from the aviation industry in automating the ICU. Because it combines "smart" technology with the necessary controls to withstand unintended consequences, PAPSIC could help ensure more informed decision making in the ICU and better patient care.

Abstract
BACKGROUND Medication use by naval aviators, either prescription or over-the-counter, is not always relayed to the flight surgeon, resulting in unsafe flying environments. Many medications have debilitating effects that prohibit their use during aviation. Education and availability of resources on approved medications for flight status personnel is lacking. METHODS A retrospective search of the Department of Defense Composite Health Care System (DoD CHCS) was conducted from five geographic locations. Basic epidemiological information was obtained to determine the most common medications (N = 70) prescribed to active-duty flight status personnel. Analysis determined their medication category, flight status designation, and a generalized location comparison. A similar control medication list for nonflight status personnel was generated from one location. RESULTS Analysis found that many medications prescribed to aviators are not approved for use in aviation and are similar to those of nonflight status personnel. There were 8 of the top 15 (53%) and 40 of the 70 (57%) most commonly prescribed medications of flight status personnel which were not approved. Similarly, 49% of total prescriptions (N = 15,652) were not approved. Little difference was found in medications among nonflight and flight status personnel, as 11 of the top 15 prescription medications (73%) were identical. DISCUSSION This research demonstrates the need for education regarding certain medications and their prohibited use during flight. Results will provide the Flight Surgeon common medications prescribed to aviators to aid them in providing a safer flying environment.Ropp LG, Haight SP, Prudhomme MB, Ropp EL.

Abstract
INTRODUCTION Evidence supports the efficacy of incorporating select recognized aviation practices and procedures into healthcare. Incident analysis, debrief, safety brief, and crew resource management (CRM) have all been assessed for implementation within the UK healthcare system, a world leader in aviation-based patient safety initiatives. Mindful application, in which aviation practices are specifically tailored to the unique healthcare setting, show promise in terms of acceptance and long-term sustainment. METHODS In order to establish British healthcare applications of aviation practices, a PubMed search of UK authored manuscripts published between 2005-2016 was undertaken using search terms 'aviation,' 'healthcare,' 'checklist,' and 'CRM.' A convenience sample of UK-authored aviation medical conference presentations and UK-authored patient safety manuscripts were also reviewed. RESULTS A total of 11 of 94 papers with UK academic affiliations published between 2005-2016 and relevant to aviation modeled healthcare delivery were found. The debrief process, incident analysis, and CRM are the primary practices incorporated into UK healthcare, with success dependent on cultural acceptance and mindful application. CRM training has gained significant acceptance in UK healthcare environments. DISCUSSION Aviation modeled incident analysis, debrief, safety brief, and CRM training are increasingly undertaken within the UK healthcare system. Nuanced application, in which the unique aspects of the healthcare setting are addressed as part of a comprehensive safety approach, shows promise for long-term success. The patient safety brief and aviation modeled incident analysis are in earlier phases of implementation, and warrant further analysis.Powell-Dunford N, Brennan PA, Peerally MF, Kapur N, Hynes JM, Hodkinson PD.

Abstract
In this article we explore the phenomenon of airmanship in commercial passenger flights, in a context of increasing standardisation of procedures and technologies. Through observation studies in cockpits and interviews we have studied pilots' practices and how they relate to the larger system of procedures and the technical environment. We find that practices are to a large extent guided by standard operating procedures, and that interchangeability of pilots and aircrafts is both a prerequisite for and enabled by this standardised regime. However, since sociotechnical systems in general - and operation of aircrafts is no exception - are inherently underspecified, the pilots' exercise of discretion in their context-sensitive adaptation of the procedures and technical environments is another prerequisite for well-functioning systems. Mastering these adaptations - and recognising the absolute delimitations of adaptations - is a central aspect of airmanship. Outside this space of manoeuvre for the pilots, the aircrafts are managed by what we call airlineship: The inter-organisational efforts to create predictability and safe practices through de-identification and interchangeability of personnel and aircrafts. Pilots are actors in sociotechnical systems that are not demarcated by the cockpits. To understand pilots' work, studies must account also for the wider sociotechnical context of organisational, regulative and techno-material structures. The article is a contribution to the a generic attempt in the field of ergonomics to contribute with models and theories that portray individuals, groups, organisations and systems in ways that keep sight of the individuals in the systems and the systems in the individuals at the same time.

Abstract
This article describes the main clinical features associated with the development and manifestations of disturbed sound perception in the members of the aeronautical personnel engaged in the Russian civilian aviation. The main expert criteria for the relationship between the diseases of the organs of hearing (as exemplified by chronic sensorineural hearing impairment) and professional occupation have been developed based on the results of the clinical and diagnostic examination with the use of whispered and loud speech acumetry, tonal threshold audiometry, speech audiometry, impedancometry and evoked optoacoustic emission. Civilian aviation sectoral approaches to the evaluation of professional suitability in terms of hearing among the aeronautical personnel are considered in accordance with the criteria adopted by the International Civil Aviation Organization (ICAO), a specialized UN agency that sets the international standards for the civilian aviation and co-ordinates its development with the purpose of enhancing the safety and effectiveness of flights. The criteria are formulated for the solution of the expert problems arising from the relationship between the professional occupation and the diseases of the organs of hearing and for the evaluation of the professional suitability in terms of hearing among the aeronautical personnel engaged in civilian aviation.

Abstract
OBJECTIVE This study evaluates the effectiveness of a training program designed to improve cross-functional coordination in airline operations. BACKGROUND Teamwork across professional specializations is essential for safe and efficient airline operations, but aviation education primarily emphasizes positional knowledge and skill. Although crew resource management training is commonly used to provide some degree of teamwork training, it is generally focused on specific specializations, and little training is provided in coordination across specializations. METHOD The current study describes and evaluates a multifaceted training program designed to enhance teamwork and team performance of cross-functional teams within a simulated airline flight operations center. The training included a variety of components: orientation training, position-specific declarative knowledge training, position-specific procedural knowledge training, a series of high-fidelity team simulations, and a series of after-action reviews. RESULTS Following training, participants demonstrated more effective teamwork, development of transactive memory, and more effective team performance. CONCLUSION Multifaceted team training that incorporates positional training and team interaction in complex realistic situations and followed by after-action reviews can facilitate teamwork and team performance. APPLICATION Team training programs, such as the one described here, have potential to improve the training of aviation professionals. These techniques can be applied to other contexts where multidisciplinary teams and multiteam systems work to perform highly interdependent activities.

Benefits of Imperfect Conflict Resolution Advisory Aids for Future Air Traffic Control. HUMAN FACTORS 2016; 58:1007-1019. [PMID: 27422153 DOI: 10.1177/0018720816655941] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Accepted: 05/24/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE The aim of this study was to examine the human-automation interaction issues and the interacting factors in the context of conflict detection and resolution advisory (CRA) systems. BACKGROUND The issues of imperfect automation in air traffic control (ATC) have been well documented in previous studies, particularly in conflict-alerting systems. The extent to which the prior findings can be applied to an integrated conflict detection and resolution system in future ATC remains unknown. METHOD Twenty-four participants were evenly divided into two groups corresponding to a medium- and a high-traffic density condition, respectively. In each traffic density condition, participants were instructed to perform simulated ATC tasks under four automation conditions, including reliable, unreliable with short time allowance to secondary conflict (TAS), unreliable with long TAS, and manual conditions. Dependent variables accounted for conflict resolution performance, workload, situation awareness, and trust in and dependence on the CRA aid, respectively. RESULTS Imposing the CRA automation did increase performance and reduce workload as compared with manual performance. The CRA aid did not decrease situation awareness. The benefits of the CRA aid were manifest even when it was imperfectly reliable and were apparent across traffic loads. In the unreliable blocks, trust in the CRA aid was degraded but dependence was not influenced, yet the performance was not adversely affected. CONCLUSION The use of CRA aid would benefit ATC operations across traffic densities. APPLICATION CRA aid offers benefits across traffic densities, regardless of its imperfection, as long as its reliability level is set above the threshold of assistance, suggesting its application for future ATC.

Predicting Air Traffic Controller Workload: Trajectory Uncertainty as the Moderator of the Indirect Effect of Traffic Density on Controller Workload Through Traffic Conflict. HUMAN FACTORS 2016; 58:560-573. [PMID: 27076095 DOI: 10.1177/0018720816639418] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Accepted: 01/16/2016] [Indexed: 06/05/2023]
Abstract
OBJECTIVE Our study investigates whether trajectory uncertainty moderates the relationship between traffic conflict and workload. Furthermore, we examine if the indirect effect of traffic density on workload through traffic conflict is conditional on the presence of trajectory uncertainty. BACKGROUND Although it is widely accepted that uncertainty related to the future trajectory of an aircraft impacts air traffic controller decision making, little is known about how the presence of trajectory uncertainty impacts controller workload. A better understanding of the impact on controller workload can improve workload prediction models for en route air traffic control. METHOD We collected data in a live operation environment, including workload ratings based on over-the-shoulder observations and real-time sector data. Hierarchical linear modeling was used to analyze the data. RESULTS Trajectory uncertainty interacts with traffic conflict in such a way that the positive relationship between traffic conflict and workload is strongest in the presence of trajectory uncertainty. Furthermore, we found that the mediating effect of traffic density through traffic conflict is conditional on the presence of trajectory uncertainty. CONCLUSION Our results indicate that workload prediction tools that do not incorporate trajectory uncertainty may underestimate workload under conditions of trajectory uncertainty, leading to possible overload situations of air traffic controllers. APPLICATION Sources that generate trajectory uncertainty, as well as their interaction effects with dynamic complexity metrics, should be acknowledged in workload prediction models to increase the predictive power of these models. Implications for future air traffic management operations as envisioned by SESAR and NextGen are discussed.

Abstract
BACKGROUND Parkinson's disease is a progressive neurodegenerative disorder which is encountered in the pilot population and has clinical features that can impact on the flying role. This retrospective study reviewed the United Kingdom Civil Aviation Authority (UK CAA) experience of Parkinson's disease. The aeromedical implications of the condition are discussed and the UK CAA policy for the certificatory assessment of pilots with Parkinson's disease is described. METHODS A search of the UK CAA medical records database from 1990 to 2015 identified 34 pilots with a diagnosis of Parkinson's disease. Data was extracted for the class of medical certificate, time from first symptoms to diagnosis, age at diagnosis, the time from diagnosis to loss of certification and the reasons for loss of certification. RESULTS Of 15 professional (Class 1) and 19 private (Class 2) pilots, the mean time from onset of symptoms to diagnosis was 36 and 19 mo, respectively. The mean ages at diagnosis were 55 and 59 yr, respectively. The mean interval from diagnosis to loss of certification was 21 (0-93) and 37 (0-84) mo, respectively. The reasons for loss of certification are considered. CONCLUSION In the UK, pilots diagnosed with Parkinson's disease may be granted medical certification depending on their functional ability and the side effect profile of medication. The aeromedical implications of Parkinson's disease and the UK CAA policy for the certification of pilots with Parkinson's disease are discussed.

Abstract
INTRODUCTION In Germany, the German Federal Police assess the performance of aviation security screeners on a regular basis. These so-called "reality tests" are unannounced examinations which aim to investigate whether airport screeners can detect forbidden items in hand luggage or attached to the body. Recent alarming results of such inspections showed clearly that the overall detection rate is in need of improvement. To achieve this, it is important to identify specific factors that influence general screening performance. This especially includes basic cognitive functions like visual screening, alertness, and divided attention, which have come more and more into focus in current fundamental research projects. This brief commentary points out critical factors, contributes background conditions in aviation security screening, and shows possible approaches for enhancement and optimization. Finally, the human aspect is discussed as not only being the weakest factor in security screening, but also one of major importance.

Occupant injury and fatality in general aviation aircraft for which dynamic crash testing is certification-mandated. ACCIDENT; ANALYSIS AND PREVENTION 2015; 79:182-189.

Abstract
Towards further improving general aviation aircraft crashworthiness, multi-axis dynamic tests have been required for aircraft certification (14CFR23.562) since 1985. The objective of this study was to determine if occupants in aircraft certified to these higher crashworthiness standards show a mitigated fraction of fatal accidents and/or injury severity. The NTSB aviation database was queried for accidents occurring between 2002 and 2012 involving aircraft certified to, or immune from, dynamic crash testing and manufactured after 1999. Only operations conducted under 14CFR Part 91 were considered. Statistical analysis employed proportion tests and logistic regression. Off-airport landings are associated with high decelerative forces; however for off-airport landings, the fraction of fatal accidents for aircraft subject to, or exempt from, dynamic crash testing was similar (0.53 and 0.60, respectively). Unexpectedly, for on-airport landings a higher fraction of fatalities was evident for aircraft whose certification mandated dynamic crash testing. Improved crashworthiness standards would be expected to translate into a reduced severity of accident injuries. For all accidents, as well as for those deemed survivable, the fraction of minor and serious injuries was reduced for occupants in aircraft certified to the higher crashworthiness standards. Surprisingly, the fraction of occupants fatally injured was not decreased for aircraft subject to dynamic crash tests. To shed light on this unexpected finding flight history, airman demographics and post-impact fires for aircraft for which dynamic crash testing is mandatory or exempt was examined. For the former cohort the median distance of the accident flight was nearly 44% higher. Aircraft subject to dynamic crash testing were also involved in a greater fraction (0.25 versus 0.12, respectively) of post-impact fires. Our data suggest that while the more stringent crashworthiness standards have mitigated minor and serious injuries, surprisingly the fraction of occupants fatally injured is unaltered. The unchanged fraction of fatal injuries may reflect partly (a) fatigue associated with longer flight distances and (b) a greater proportion of post-impact fires.

Abstract
Thanks to the increasing availability of consumer head-mounted displays, educational applications of immersive VR could now reach to the general public, especially if they include gaming elements (immersive serious games). Safety education of citizens could be a particularly promising domain for immersive serious games, because people tend not to pay attention to and benefit from current safety materials. In this paper, we propose an HMD-based immersive game for educating passengers about aviation safety that allows players to experience a serious aircraft emergency with the goal of surviving it. We compare the proposed approach to a traditional aviation safety education method (the safety card) used by airlines. Unlike most studies of VR for safety knowledge acquisition, we do not focus only on assessing learning immediately after the experience but we extend our attention to knowledge retention over a longer time span. This is a fundamental requirement, because people need to retain safety procedures in order to apply them when faced with danger. A knowledge test administered before, immediately after and one week after the experimental condition showed that the immersive serious game was superior to the safety card. Moreover, subjective as well as physiological measurements employed in the study showed that the immersive serious game was more engaging and fear-arousing than the safety card, a factor that can contribute to explain the obtained superior retention, as we discuss in the paper.

Abstract
For many years hospitals have been implementing crew resource management (CRM) programs, inspired by the aviation industry, in order to improve patient safety. However, while contributing to improved patient care, CRM programs are controversial because of their limited impact, a decrease in effectiveness over time, and the underinvestment by some caregivers. By analyzing the space shuttle Challenger accident, the objective of this article is to show the potential impact of the professional culture in decision-making processes. In addition, to present an approach by cultural factors which are an essential complement to current CRM programs in order to enhance the safety of care.

Causes of fatal accidents for instrument-certified and non-certified private pilots. ACCIDENT; ANALYSIS AND PREVENTION 2014; 72:370-375.

Abstract
Instrument certification (IFR) enhances a pilot's skills in precisely controlling the aircraft and requires a higher level of standards in maintaining heading and altitude compared with the less stringent private pilot certificate. However, there have been no prior studies to compare fatal accident causes for airmen with, and without, this rating, The NTSB accident database was queried for general aviation fatal accidents for private pilots with, and without IFR certification. Exact Poisson tests were used to calculate whether two rate parameters were equal (ratio of 1), normalized to the number of IFR-rated pilots and flight hours in the given time period. Proportion tests were used to determine whether there were significant differences in fatal accident causes between IFR-certified and non-certified pilots. A logistic regression for log-odds success was used in determining the trend and effect of age on fatal accident rates. IFR certification was associated with a reduced risk of accidents due to failure to maintain obstacle/terrain clearance and spatial disorientation for day and night operations respectively. In contrast, the likelihood of fatal accident due to equipment malfunction during day operations was higher for IFR-certified pilots. The fatal accident rate decreased over the last decade for IFR-certified but not for non-IFR-certified private pilots. However, the overall accident rate for IFR-certified private pilots was more than double that of the cohort lacking this certification. Finally, we found a trend for an increased fatality rate with advancing age for both group of pilots. Our findings informs on where training and/or technology should be focused. Both training for aerodynamic stalls, which causes over a quarter of all fatal accidents, should be intensified for both IFR-certified and non-certified private pilots. Similarly, adherence to minimum safe altitudes for both groups of pilots should be encouraged toward reducing the fatal accidents rate due to failure to maintain obstacle/terrain clearance. For night operations, the high percentage of accidents due to spatial disorientation for non-IFR certified airmen suggests that additional training be required for such operations or such flights carry restrictions for this subset of pilots.

Abstract
In reference to the original research questions, there is organizational documented support for the QRG. FLMs perceived the QRG to have both effectiveness and utility. Both less experienced FLMs and more experienced FLMs found the QRG to be helpful, as indicated by intended use, with more experienced FLMs indicating a higher intended use. The ATO Office Safety Programs Fatigue Risk Management Group has requested an expansion of the QRG, including fatigue-related issues. Overall, the QRG has proven to be a useful and convenient document for all FLMs. As it becomes a recognizable and essential resource in both the training and management tool box, the use of the QRG will likely grow.

Abstract
Part 1 of this study sequence developed a human factors/ergonomics (HF/E) based classification system (termed HFACS-MA) for safety audit findings and proved its measurement reliability. In Part 2, we used the human error categories of HFACS-MA as predictors of future safety performance. Audit records and monthly safety incident reports from two airlines submitted to their regulatory authority were available for analysis, covering over 6.5 years. Two participants derived consensus results of HF/E errors from the audit reports using HFACS-MA. We adopted Neural Network and Poisson regression methods to establish nonlinear and linear prediction models respectively. These models were tested for the validity of prediction of the safety data, and only Neural Network method resulted in substantially significant predictive ability for each airline. Alternative predictions from counting of audit findings and from time sequence of safety data produced some significant results, but of much smaller magnitude than HFACS-MA. The use of HF/E analysis of audit findings provided proactive predictors of future safety performance in the aviation maintenance field.

Abstract
This circumstance leads to considerable mistakes it creation of SPZ borders of the airports, in some cases it impedes development of the latters and causes objective difficulties for hygienic assessment of projects. In this article the results of studies on the creation and validation of two new domestic methods for the construction of impact zones of aircraft noise and dispersion of the concentrations of pollutants in assessing the negative impact of airports are considered. Both branch methods agreed upon with the Ministry of Transport have been harmonized with ICAO (International Civil Aviation Organization) requirements. The results of full-scale measurements have confirmed the possibilities of developed software for their implementation in the formation of a common SPZ border of an airport.

Abstract
INTRODUCTION Transient global amnesia (TGA) is an episode of severe anterograde amnesia of sudden onset, characteristically lasting 4 to 6 h. Patients become disorientated in time and place, but not in person. Automated motor tasks are preserved; however, the retention of new information is impaired, with clear implications to a pilot's fitness to fly. This study examines the United Kingdom Civil Aviation Authority (UK CAA) experience of pilots with TGA and compares it to the medical literature. METHODS The UK CAA medical records database was searched for subjects who had reported a history of TGA between the years 1990 and 2010. Subject age and gender, the frequency and duration of episodes, the follow-up period, precipitants, and associated features were recorded. A literature search for papers with similar information was undertaken. RESULTS The UK CAA database showed 29 subjects who had held a UK CAA medical certificate with a history of TGA. There were 28 male individuals and 1 female. The mean age was 59 yr. The mean follow-up period was 3.4 yr. The average duration of an episode was 2.8 h. Activity, stress, or exposure to cold water were reported as possible precipitants by 16 subjects (55%). There were 6 subjects (21%) who had a history of migraine and 10 (34%) who had a history of hypertension. From the literature, 10 papers were reviewed and compared to our study group. DISCUSSION The aeromedical implications of TGA, including its etiology, associations, misdiagnosis, and recurrence risk are considered. A policy for the certification of pilots following TGA is proposed.

Abstract
This paper describes research that aims to provide the overall scientific basis for implementation of a Fatigue Risk Management System (FRMS) for French regional airlines. The current research has evaluated the use of different tools and indicators that would be relevant candidates for integration into the FRMS. For the Fatigue Risk Management component, results show that biomathematical models of fatigue are useful tools to help an airline to prevent fatigue related to roster design and for the management of aircrew planning. The Fatigue Safety assurance includes two monitoring processes that have been evaluated during this research: systematic monitoring and focused monitoring. Systematic monitoring consists of the analysis of existing safety indicators such as Air Safety Reports (ASR) and Flight Data Monitoring (FDM). Results show a significant relationship between the hours of work and the frequency of ASR. Results for the FDM analysis show that some events are significantly related to the fatigue risk associated with the hours of works. Focused monitoring includes a website survey and specific in-flight observations and data collection. Sleep and fatigue measurements have been collected from 115 aircrews over 12-day periods (including rest periods). Before morning duties, results show a significant sleep reduction of up to 40% of the aircrews' usual sleep needs leading to a clear increase of fatigue during flights. From these results, specific guidelines are developed to help the airlines to implement the FRMS and for the airworthiness to oversight the implementation of the FRMS process.

Abstract
Other industries and certain healthcare specialties have employed a variety of methods to improve safety and quality of services. Techniques such as industry-wide standardized collection and reporting of error data, standardization of practice through checklists, application of electronic health records, and simulator-based interdisciplinary training have improved outcomes in aviation, anesthesiology, and surgery. Although traditionally the clinical laboratory has concentrated on analytical performance, pre- and post-analytical aspects of laboratory services may also be improved through the application of these methods.

Abstract
OBJECTIVE This article aims to explore the nature and resolution of breakdowns in coordinated decision making in distributed safety-critical systems. BACKGROUND In safety-critical domains, people with different roles and responsibilities often must work together to make coordinated decisions while geographically distributed. Although there is likely to be a large degree of overlap in the shared mental models of these people on the basis of procedures and experience, subtle differences may exist. METHOD Study 1 involves using Aviation Safety Reporting System reports to explore the ways in which coordinated decision making breaks down between pilots and air traffic controllers and the way in which the breakdowns are resolved. Study 2 replicates and extends those findings with the use of transcripts from the Apollo 13 National Aeronautics and Space Administration space mission. RESULTS Across both studies, breakdowns were caused in part by different types of lower-level breakdowns (or disconnects), which are labeled as operational, informational, or evaluative. Evaluative disconnects were found to be significantly harder to resolve than other types of disconnects. CONCLUSION Considering breakdowns according to the type of disconnect involved appears to capture useful information that should assist accident and incident investigators. The current trend in aviation of shifting responsibilities and providing increasingly more information to pilots may have a hidden cost of increasing evaluative disconnects. APPLICATION The proposed taxonomy facilitates the investigation of breakdowns in coordinated decision making and draws attention to the importance of considering subtle differences between participants' mental models when considering complex distributed systems.
