INTRODUCTION: Air taxis conduct nonscheduled transport and employ aircraft in various performance categories hereafter referred to as low, medium, and high performance, respectively. No study has yet addressed fixed-wing air taxi safety by performance category. Herein, we compared accident rates/occupant injury across air taxi airplane fleets grouped by performance category and identified human factors contributing to fatal accidents for airplanes in that category with the highest mishap rate.METHODS: Accidents (20042018) in the United States were identified from the National Transportation Safety Board database. General Aviation/Part 135 Activity Surveys provided annual fleet times. Fatal accident contributing factors were per the Human Factors Classification System (HFACS). Statistics utilized Poisson distributions, Chi-Square/Fisher, and Mann-Whitney tests.RESULTS: There were 269 air taxi mishaps (53 fatal) identified. Over the 15 yr, the accident rate (1.10/million flight hours-all categories) declined 50%, largely due to a reduction in medium/high performance category airplane crashes. However, little temporal change was observed for low performance airplanes (1.5/million flight hours) and injury severity trended higher. At the aircrew/physical environment levels, HFACS revealed decision (improper choices), skill-based (stick and rudder) and perceptual (night, instrument conditions) errors contributing to > 60% of fatal accidents involving low performance airplanes. At the organizational level, failing to correct problems, time pressures, and incentive systems contributed to 16% of fatal mishaps.CONCLUSION: Safety deficits remain for the low performance category air taxi fleet warranting increased pilot instrument flight training/utilization of the mandatory 3-axis autopilot in degraded visibility. Safety culture improvements to address issues of personnel/equipment/training deficiencies, failing to correct problems, and time pressures/a safety-compromising incentive system all need to be addressed.Budde D, Hinkelbein J, Boyd DD.

Streszczenie:

National Transportation Safety Board accident data for 1983-1991 were used to compare those general aviation accident cases that involved spatial disorientation (SD) with all others. About 2.1% of general aviation airplane accidents involved SD. Those accidents were associated with low ceilings, restricted visibility, precipitation, darkness and instrument flight conditions. Pilots in certain professions, particularly those in business, were more involved in SD accidents. Pilots in SD accidents were more often under pressure, fatigue, anxiety, physical impairment and alcohol or drugs. The pilots' total and night flying experience were inversely related to involvement in SD accidents. Spatial disorientation accidents accounted for a small number of crashes, but they were very severe-fatalities occurred in 92%, they accounted for 9.9% of the fatal accidents, 11% of the fatalities and in 95% the aircraft were destroyed. The results suggest that the pilots in SD accidents lacked the flight experience necessary to recognize or cope with the stimuli that induce SD, which was compounded by fatigue, alcohol/drugs or pressure and other psychological and physical impairments. Specific exposure to conditions leading to SD in training of general aviation and all pilots should be evaluated to help them to recognize it, and the techniques used by experienced pilots to combat its onset and effects should be studied and used in training. Improved human factors engineering of the cockpit instrumentation is also needed.

INTRODUCTION: Loss-of-control (LOC) is the major cause of transport airplane mishaps. There have been many published reports and papers examining these accidents. While these studies did mention spatial disorientation (SD) as a cause or a factor, none of them analyzed it further. The present study uses transport and commuter airplane mishap data for a recent 35-yr period and examines the results of those mishaps involving spatial disorientation.METHOD: We identified LOC and SD accidents from five national aviation accident organizations and two independent groups. Only “normal” operations (air carrier, noncommercial transportation, ferry flights, and training) were considered. We reviewed transport and commuter airplane accidents using the published reports and identified 94 involving SD.RESULTS: We found the distribution of SD mishaps differs from LOC mishaps. During initial climb, there were relatively fewer SD mishaps (16%) than LOC mishaps (31%). During enroute climb SD has relatively more mishaps (18%) than LOC (11%). During go-around or missed approach phases, there were relatively more SD mishaps (21%) than LOC mishaps (4%). Perhaps the most significant observation was an increasing number of SD mishaps during the period reviewed.DISCUSSION: There are several possible reasons for the increasing numbers of SD mishaps over the study period from 1981 to 2016. Somatogravic illusion during go-around or missed approach accounts for only some of this increase. There is insufficient data to determine the reason for the remaining increase.Newman RL, Rupert AH.

BACKGROUND: Sightseeing operations are characterized by the presence of passengers as well as favorable light and weather conditions. They include both fixed-wing aircraft and helicopters, an aspect that allows for a comparison of these two types of aircraft in similar operations.METHODS: A total of 95 accident reports from 2008 until 2018 were extracted from the NTSB online database, with each mentioning commercial sightseeing as their operation.RESULTS: Out of a total of 95 accidents, 16 were fatal with a total of 58 people suffering fatal injuries. On average 3.625 people died in each fatal accident. There were significantly more accidents in Alaska and Hawaii than expected. There were significantly more accidents caused by the maintenance crew in helicopters than in airplanes, but significantly more pilot-related accidents in fixed-wing aircraft compared to helicopters. Despite favorable light and weather conditions, 37 accidents reported the environment as a contributing factor to the accident.CONCLUSION: Sightseeing accidents show a pronounced difference between helicopters and airplane accidents that point to different approaches when improving safety in either category. Although night and instrument meteorological conditions are largely absent in the dataset, wind conditions and unsuitable terrain are frequently mentioned. The experience of the pilots and the specific geography of the sightseeing area are likely to affect operational safety the most. The specific dangers of unsuitable terrain affect both helicopters and fixed-wing operations and may be assuaged by specific training or briefings.de Voogt AJ, Hummel Hohl C, Kalagher H.

Loss of control is one of the leading factors in hull losses and fatalities in airline aircraft. To reduce the risk of this type of accident, four types of airplane upset recovery training have been developed (ground-based flight simulation, aerobatic flight, ground-based flight simulation with aerobatic flight, and in-flight simulation). These were evaluated during in-flight reenactments of fatal, hull loss airline airplane accidents. A between-subjects design, with five groups of eight nonmilitary pilots flying in their probationary year for airlines, was used to evaluate these types of training. Each group had received a different type of training, including one group that had received no training. Each pilot completed a 1.4-hr evaluation flight in which eight airplane upsets were introduced. For some scenarios, training clearly works – specifically, 39 evaluation pilots recovered from the wind shear upset. But few evaluation pilots used bank to change the direction of the lift vector to recover from nose-high upsets. Further, very few used differential thrust to recover from rudder- or aileron-induced roll upsets (use of alternate controls). Finally, recovery attempts from icing-induced stalls were generally inadequate.

(1) Background: It is difficult for accident investigators to objectively determine whether spatial disorientation may have contributed to a fatal airplane accident. In this paper, we evaluate three methods to reconstruct the possible occurrence of the somatogravic illusion based on flight data recordings from an airplane accident. (2) Methods: The outputs of two vestibular models were compared with the “standard” method, which uses the unprocessed gravito-inertial acceleration (GIA). (3) Results: All three methods predicted that the changing orientation of the GIA would lead to a somatogravic illusion when no visual references were available. However, the methods were not able to explain the first pitch-down control input by the pilot flying, which may have been triggered by the inadvertent activation of the go-around mode and a corresponding pitch-up moment. Both vestibular models predicted a few seconds delay in the illusory tilt from GIA due to central processing and sensory integration. (4) Conclusions: While it is difficult to determine which method best predicted the somatogravic illusion perceived during the accident without data on the pilot’s pitch perception, both vestibular models go beyond the GIA analysis in taking into account validated vestibular dynamics, and they also account for other vestibular illusions. In that respect, accident investigators would benefit from a unified and validated vestibular model to better explain pilot actions in accidents related to spatial disorientation.

BACKGROUND/OBJECTIVE: The COVID-19 virus has caused over 582,000 deaths in the United States to date. However, the pandemic has also afflicted the mental health of the population at large in the domains of anxiety and sleep disruption, potentially interfering with cognitive function. From an aviation perspective, safely operating an aircraft requires an airmans cognitive engagement for: 1) situational awareness, 2) spatial orientation, and 3) avionics programming. Since impaired cognitive function could interfere with such tasks, the current study was undertaken to determine if flight safety for a cohort of single engine, piston-powered light airplanes was adversely affected during a period of the pandemic (MarchOctober 2020) prior to U.S. approval of the first COVID-19 vaccine.METHODS: Airplane accidents were per the National Transportation Safety Board Access<sup/> database. Fleet times were derived using Automatic Dependent Surveillance-Broadcast. Statistics used Poisson distributions, Chi-squared/Fisher, and Mann-Whitney tests.RESULTS: Little difference in accident rate was evident between the pandemic period (MarchOctober 2020) and the preceding (JanuaryFebruary) months (19 and 22 mishaps/100,000 h, respectively). Similarly, a proportional comparison of accidents occurring in 2020 with those for the corresponding months in 2019 failed to show over-representation of mishaps during the pandemic. Although a trend to a higher injury severity (43% vs. 34% serious/fatal injuries) was evident for pandemic-period mishaps, the proportional difference was not statistically significant when referencing the corresponding months in 2019.CONCLUSION: Surprisingly, using accidents as an outcome, the study herein shows little evidence of diminished flight safety for light aircraft operations during the COVID-19 pandemic.Boyd DD.

This thesis describes original research that examines the extent to which organisational culture, and psychosocial aspects specifically, relate to individuals??? ???normal??? performance within Australian Defence Force (ADF) aviation. The primary rationale for the research relates to the ???safety record??? of ADF aviation, whereby more than fifty ???peace time??? fatalities have occurred in ADF aviation accidents since 1990 and many of these have links to organisational culture attributes. The secondary rationale relates to a more general perspective: previous research identifies human functioning in military aviation ??? more than any other aviation domain ??? as being dependent upon psychosocial attributes including interpersonal collaboration, communication and coordination. However, the depth to which such qualities impact the safety of a sociotechnical system remains substantially uncharted. This thesis firstly examines both scientific and Australian military literature on organisational behaviour, culture and human factors. Subsequently, it describes the design and implementation of a new 45-item questionnaire ??? the Australian Defence Force Aviation Questionnaire (ADFAQ). More than four hundred ADF aircrew and engineers completed the ADFAQ. The data analysis involved quantitative and qualitative consideration of survey responses and comparisons between numerous demographic criteria. Following this, the thesis describes the design and implementation of an interview study that was designed to both cross-examine key ADFAQ results and explore more deeply other issues that were only superficially identified by the (largely psychometric) composition of the ADFAQ. The research results offer three main contributions to scientific knowledge. These relate to: (1) the efficacy of triangulated and contextualised methodology in building an understanding of organisational culture; (2) the nature of the safety culture concept and its relationship with organisational culture; and (3) rank-based homogeneity of attitudes. This research shows that survey methodologies are not a panacea, but they can illuminate the nature of attitudes to safety and provide empirical guidance for other methods to explore more deeply the cultural roots of such attitudes and associated behaviours.

Our intended topic is a general discussion of the basic elements of liability related to airline accidents to which fully automated cockpits have constituted an associated contributory factor. In addition we addressed the liability of air carriers arising from injuries or death caused to passengers traveling on international flights. For this purpose, we reviewed the Warsaw System and the different international instruments that constitute it. We also reviewed principles of common law applicable to aircraft manufacturers and the "Free Flight" as an example of the growing automation environment, which is a general benefit to commercial aviation but also a likely contributory cause for accidents in particular cases. In the last part we briefly discuss a personal view regarding the interplay between manufacturers and airlines under the 1999 Montreal Convention, which is an international treaty unifying the desegregated Warsaw System into one single instrument that is expected to enter into force in a few years.

In questo lavoro di tesi si è svolto in prima istanza uno studio preliminare atto a individuare una miscela rappresentativa del combustibile aeronautico Jet A-1, a partire dai limiti imposti dal mercato e dagli standard europei. Esso è stato identificato come miscela di n-decano e toluene in composizione relativa tale da avere proprietà chimiche e fisiche simili rispetto alla miscela reale. Successivamente è stato individuato un set ridotto di cinetiche (reazioni) e di composti tale da rendere possibile l’implementazione in codici fluidodinamici computerizzati (CFD). Ciò è stato ottenuto utilizzando un'analisi di sensitività numerica e utilizzando il software Cantera. Nella seconda fase del lavoro è stato utilizzato il software di simulazione dinamica di incendi denominato Fire Dynamic Simulator (FDS) sviluppato dal National Institute of Standards and Technology (NIST). Tale software è stato applicato per la simulazione degli incendi di pozza (pool fire) e per la simulazione della dispersione dei vapori del surrogato Jet A-1 su pista, seguito da un innesco ritardato (flash fire). Nel caso del pool fire sono state valutate le temperature e i flussi termici radiativi in funzione del tempo e dello spazio. Nel caso della dispersione dei vapori del combustibile in atmosfera è stata invece valutata la frazione molare di combustibile presente nell’aria rispetto alla distanza dal punto sorgente, ed è stata valutata la dimensione della nuvola infiammabile avendo come riferimento il limite inferiore di infiammabilità della miscela in esame. Il confronto con i dati sperimentali presenti in letteratura, in particolare per il pool fire - nei termini di flusso termico rispetto alla distanza dell’incendio - ha evidenziato una notevole discrepanza con i valori ottenuti dal modello di default di FDS, mentre ha invece confermato la bontà dei risultati ottenuti utilizzando il modello cinetico semplificato – ma di dettaglio - ottenuto in questo lavoro.

The aim of this thesis is to identify the liability and damage on tort liability of international carriers and the burden of the damage which caused by their employee pilots under Taiwan Laws and the Convention, study and learn experience from the historical case against with current rules, to preclude or reduce the happenstance of the air traffic incident and accident. The first chapter of this proposal describes the determined of the motive, research method, scope, goal of this thesis, and the definition of the terms. The second chapter of this proposal is a review of the literature, by means of addressing theoretical aspects of the Torts, analyzes the subjective and objective elements of tort liability under Taiwan Law, and further explores the damages compensation of tort liability in terms of scope, method, liability subject as well. The third chapter introduces the relevant contents of passenger recovery for the damages by the Conventions, including Montreal Convention and Warsaw Convention, with the aspects of the scope, validity, and limitation. It also elaborates the objective and subjective norms of negligence, and the execution of difficulty in current. The fourth chapter describes the relevant contents of the passenger‘s damages recovery by Taiwan Law, which include Civil code, Civil Aviation Act, Act Governing the Choice of Law in Civil Matters Involving Foreign Elements, and Regulations of Compensation For Damage Caused to Air Passengers & Freight. It also analyzes the Legal precedent from Taiwan court, and compares with the section defines the extent of application against from the Conventions. The fifth chapter discusses about the employer’s joint liability, the condition of waving liability, the obligation and right and benefit of the employee pilots, the legal precedence of the pilot negligence, addressing both empirical and theoretical aspects of recent aviation accident and incident, which advised by the recommendation method for preventing the event occurred as well included in this proposal. By analyzing the relationship between passenger’s benefits and air carrier’s liability in airplane accidents, this thesis suggests to establish accurately pilots volunteer report system, which is very important for an effective safety flight environment. In addition, this thesis suggests to add a specific Article in Civil Aviation Act to supersede the Taiwan Civil code Article 188, to allocate heavier burden on the employer for compensating any injury which the employee has wrongfully caused to another in the performance of his duties, even the employer has exercised reasonable care in the selection of the employee and in the supervision of the performance of his duty in airplane accidents. Adjusting the liability between air carriers and pilots is crucial for passenger’s compensation. Meanwhile, this thesis suggests deleting the provision of “the employer who has made compensation as specified in the preceding paragraph may claim for reimbursement against the employee committed the wrongful act”, and requires the air carries to purchase mandatory liability insurance. Since the reimbursement of the airplane accidents is a huge amount, asking an employee to reimburse is not practical, because the employee’s salary for his/her entire life is not enough for the reimbursement.

The risk management is an executive routine of risk identification, appraisal and control. If used wisely, it could greatly improve both the management operations and the security level. The point of risk management is not to avoid the risk, but to face the risk by using a systematic way which therefore reduces the risk. However, due to time restrictions and limited resources, the problem solving methods should be efficient, low risk, and economical. In addition, risk management is highly related to the aviation safety because related personnel’s ultimate goal is to prevent similar accidents, investigate causes, and improve the efficiency of risk management. This research applies risk management procedures to the domestic civil aviation industry fixed-wing aircraft aviation safety analysis. First, this essay uses aviation and transportation management safety documents as the research foundation to emphasize the importance of an aviation risk management to the aviation transportation industry. Next, the essay bases the research on a causes/factors statistics of domestic civil aviation industry fixed-wing aircraft first and second level accidents during the period of 1998-2007. The causes/ factors of aviation accidents can be divided into seven different categories including pilots, other personnel, weather, airports, tower controls, navigational aids, and engine/ aircraft structure. Afterward, the research combines the statistics and professional accident investigation contents to calculate an aviation accident risk ratio, and to acknowledge a risk matrix. According to my research, pilots are responsible for most accidents (14.3%) based on the accident causes/factors. The least frequent causes for accidents are airports, tower controls, navigational aids, and engines (0%). In addition, aircraft structures lead to the highest damage range (270 risk points), while airports, tower controls, navigational aids, and engines also have the smallest damage range (0 point). Furthermore, the risk area analysis indicates that pilots, other person personnel, and weather are in the high-risk area, and that aircraft structure is in the middle-risk range, and airports, tower controls, navigational aids, and engines are in the low risk area. Lastly, this research presents aviation accident risk management strategies and suggestions for risk improvements.

Since crises have become an inevitable, natural feature of the business world, managing brands during crisis has also become an important source of competitive advantage. Thus, there is a growing need to understand determinants of crisis, which have become an integral part of today's world. The aim of this chapter is to explain the determinants of successful brand management during crises based on the case of Turkey. Crises may arise for various reasons, such as natural disasters, accidents, financial/political/product harm-related problems, product recall incidents, and many others. Since brands are very affected by many dynamic forces—political-economic-social and technological—brand managers need to be prepared to overcome crises without harming the brand equity. Moreover, the integration of brand management theory, which originated and was dominated by Western researchers, with recent case examples from an emerging country, constitutes the originality of the chapter. In this chapter, two boycott cases, an airplane disaster case and a product recall case, from Turkey are summarized to contribute to the existing Western literature.

This chapter discusses the distinction between accidents and mistakes. Much of the law of torts centers on negligent accidents—whether with cars, airplanes, guns, or simply walking on a slippery floor. The important feature of torts, as opposed to crime, is that there is no liability absent harm to the plaintiff. For example, there is no liability for merely attempting or risking harm. In domestic criminal law, accidents become relevant only in what can be called the pattern of harmful consequences, that is, where there is a causal chain between the action and the harm. Meanwhile, according to Article 31(1) of the Rome Statute, a mistake of fact is relevant only if it negates the mental element required for the crime.

In this last decade of the twentieth century, hazards have become a part of everyday life as they have never been before. It is not that life, at least in advanced industrial societies, is more dangerous. Indeed, by any measure, the average person is safer and is likely to live longer and with greater leisure and well-being than at earlier times. Nevertheless, the external world seems replete with toxic wastes, building collapses, industrial accidents, groundwater contamination, and airplane crashes and near collisions. The newspapers and television news daily depict specific hazard events, and a parade of newly discovered or newly assessed threats—the "hazard-of-the-week" syndrome—occupies the attention of a host of congressional committees, federal regulatory agencies, and state and local governments. Seemingly any potential threat, however esoteric or remote, has its day in the sun. How is it, then, that certain hazards pass unnoticed or unattended, growing in size until they have taken a serious toll? How is it that asbestos pervaded the American workplace and schools when its respiratory dangers had been known for decades? How is it that after years of worry about nuclear war, the threat of a "nuclear winter" did not become apparent until the 1980s? How is it that the Sahel famine of 1983 to 1984 passed unnoticed in the hazard-filled newspapers of the world press, until we could no longer ignore the specter of millions starving? How is it that America "rediscovered" poverty only with Michael Harrington's vivid account of the "other Americans" and acknowledged the accumulating hazards of chemical pesticides only with Rachel Carson's Silent Spring1? How is it that during this century a society with a Delaney amendment and a $10 billion Superfund program has allowed smoking to become the killer of millions of Americans? And why is it that the potential long-term ecological catastrophes associated with burning coal command so much less concern than do the hazards of nuclear power? These oversights or neglects, it might be argued, are simply the random hazards or events that elude our alerting and monitoring systems. After all, each society has its "worry beads," particular hazards that we choose to rub and polish assiduously (Kates 1985).

This chapter explores the use of “black boxes” in surgeries. When an airplane goes down, there is an urgent search for the plane’s black box. The black box contains both the audio recording of all cockpit discussion, as well as a recording of flight instrument readings. These two flight recorders are required by international regulation and together offer the best possibility of learning what happened in the minutes preceding any aviation accident or incident. A version of this kind of recording technology—which captures medical conversation and physiological parameters, allowing for postsurgery analysis—is starting to make its way into the world of medicine. However, this new technology raises important questions: Will surgeons and other health professionals be put in malpractice jeopardy by such new information? Will patients and their families become more likely to sue? Will more information undermine patient trust? Ultimately, medicine aspires to create a culture of continual improvement. As such, one can imagine black box technology entering medicine widely over the next years.

Chapter 2 presents a revisionist account of Osama Bin Laden’s personal experience of the West and his attachments to Britain. Bin Laden was born in 1957 in Riyadh, the only child of Muhammed Bin Laden’s tenth wife, A’alia Ghanem. After his parents’ divorce, Bin Laden spent his childhood years in the mother’s household. His father, a rich entrepreneur, died in an airplane accident when Osama was ten. The young Bin Laden had a cosmopolitan and in some ways rather secular upbringing. The turning point in his life came in 1976, when as a student he was exposed to Egyptian Islamist radicals in Jeddah, Saudi Arabia. Al Qaeda was founded in August 1988 in Bin Laden’s house in Peshawar, Pakistan. It was, from the start, dedicated to a global jihad. The chapter uses Bin Laden’s personal journal and files taken from his house in Abbottabad, Pakistan, and recently published books written by his close associates, to correct simplistic views of Bin Laden as a “man in a cave.”

Everyone lives with risk, every day. In the United States, more than 100,000 persons die from accidents every year, nearly half of them on the country’s roads. Worldwide, an average of more than 5000 coal miners perish underground annually, a toll often forgotten by those who oppose nuclear power generation on grounds of safety. From insect bites to poisoned foods and from smoking to travel, risk is unavoidable. Certain risks can be mitigated through behavior (not smoking, wearing seatbelts), but others are routinely accepted as inescapable. A half century ago, long before hijackings and airport security programs, the number of airline travelers continued to increase robustly even as airplanes crashed with considerable frequency. Today, few drivers or passengers are deterred by the carnage on the world’s roads, aware of it though they may be. Risk is part of life. Risk, however, also is a matter of abode, of location. Who, after experiencing or witnessing on television the impact of a hurricane, a tornado, an earthquake, a volcanic eruption, a flood, a blizzard, or some other extreme natural event, has not asked the question: “Where in the world might be a relatively safe place to live?” Geographers, some of whom have made the study of natural hazards and their uneven distribution a research priority, don’t have a simple answer. But on one point they leave no doubt: people, whether individually or in aggregate, subject themselves to known environmental dangers even if they have the wherewithal to avoid them. Many Americans build their retirement or second homes on flood-prone barrier islands along coastlines vulnerable to hurricanes. The Dutch, who have for many years been emigrating from the Netherlands in substantial numbers, are leaving for reasons other than the fact that two-thirds of their country lies below sea level. From Indonesia to Mexico, farmers living on the fertile slopes of active volcanoes not only stay where they are, but often resist even temporary relocation when volcanic activity resumes. From Tokyo to Tehran, people continue to cluster in cities with histories of devastating earthquakes and known to be situated in perilous fault zones. Fatalism is a cross-cultural human trait.

Streszczenie:

The paper presents three types of a passive safety containment for a near future BWR. They are tentatively named Mark S+, Mark D and Mark X containments in the paper. They all have a leak tight secondary containment vessel (SCV) in order to meet the reactor site criteria without relying on an active standby gas treatment system at a DBA LOCA. One of their common features is very low peak pressure at severe accidents without venting the containment atmosphere to the environment. The containment pressure can be limited within the design pressure. Even if a large amount of hydrogen is generated at a severe accident, it can be released into the SCV. Hydrogen detonation or deflagration is completely prevented without using igniters. Another feature is the capability to submerge the PCV and the RPV above the core level without relying on accident management. The core debris is completely submerged not only ex-vessel but also in-vessel. The third feature is robustness against external events such as a large commercial airplane crash. All the containments have built-in passive safety systems (BIPSS) including a passive containment cooling system (PCCS) and a passive cooling core catcher that has radial cooling channels. The Mark S+ and Mark D containments are applicable to a large power BWR up to 1830 MWe. The SCV is made of steel-concrete composite. The PCV can be vented into the inerted part of the SCV at a severe accident. The Mark X containment has the steel secondary containment vessel (SSCV) and can be cooled by natural convection of outside air. It can accommodate a medium power BWR up to about 1000 MWe and has a permanent grace period without replenishing the PCCS pool. In all cases the plants have active and passive safety systems constituting in-depth hybrid safety (IDHS). The IDHS provides in-depth protection against severe accidents and also enables N+2 design. All the three containments coupled with the IDHS can potentially provide an evacuation free plant at a severe accident caused by severe natural disasters such as a giant earthquake, a tsunami, a mega hurricane, and so on.

Aero engine is essentially the heart of an airplane. However, the high temperature and high pressure working environment of the aero engine can easily lead to fatigue cracks in turbine disks, and result in serious accidents. Therefore, early disk crack diagnosis is very important to guarantee safe flight of the airplane and reduce its maintenance cost, which, however, is challenging due to the difficulty in building a complex physical model under variable operating speeds. To tackle this problem, a novel deep convolutional neural network (CNN)-based method is proposed for early disk crack diagnosis. CNN, as one of the deep learning structures, can learn deep-seated features directly and automatically from the raw data without the need of physical model or prior knowledge. It shows the potential to deal with the challenge of early disk crack diagnosis. Since the proposed diagnosis method is signal-level, the collected vibration signals can be input into the CNN architecture directly without the need of feature extractor. In this paper, the vibration signals at both the beginning and the end of the test are used for training the CNN model, then the rest signals are input into the trained model as test data to diagnose when the incipient disk crack is generated. Experimental study conducted on the fatigue test of a real turbine disk has proved the effectiveness and robustness of the proposed method for early disk crack diagnosis. Meanwhile, comparison study with some state-of-the-art methods is also performed, and further highlights the superiority of the proposed method.

Nowadays, fiber reinforced plastic (FRP) has been widely used in many areas such as auto mobile, airplane and marine vessel due to its high specific strength, good corrosion resistance, relatively low cost and so on. However, it still remains unknown that what kind of damage will happen in the internal structure when an automobile, which is made from FRP, has a slight impact with something such as a wall. Then the following road safety of the automobile cannot be guaranteed because certain parts may be exposed to damage in what seems even like a slight impact. In addition, it is well known that initial fracture can bring damage and great effect to the mechanical properties of the FRP material. The novelty of this paper is that the object of this research is micro crack such as transverse crack. While, almost previous report is aimed at delamination. Actually, before the delamination happens, micro crack has already occurred. The mechanical property of FRP is beginning to decrease by delamination. However, when the delamination occurred in the FRP is examined, it is already too late because the delamination can bring great influence to the safety of the FRP products. Therefore, it is important to investigate and detect the presence of micro crack with ultrasonic wave. In this way, some accidents might be avoided. While, because of the variety of the constraints in the fracture mechanism, the damage behavior is very difficult to evaluate and there are rarely researches and data on it. Although damage assessment by visual observation and the durable service life on FRP has become a general tendency in these recent years, the appropriate way of non-destructive examination has not been confirmed yet. The purpose of this study is to investigate the possibility of non-destructive examination with ultrasonic wave testing for mechanical damage of glass fiber reinforced plastics (GFRP). The possibility of dividing of Lamb wave modes by reducing the thickness of samples was confirmed and the variance of distribution of frequency of S0 mode wave by micro fracture in GFRP.

European Advanced Boiling Water Reactor (EU-ABWR) is developed by Toshiba. EU-ABWR accommodates an armored reactor building against Airplane Crash, severe accident mitigation systems, the N+2 principle in safety systems, the diversity principle and a large output of 1600 MWe. These features enable EU-ABWR’s design objectives and principles to be consistent with the safety requirements of Western European Nuclear Regulators’ Association (WENRA) and Finnish YVL guides. By designing safety features of the EU-ABWR based on Defense in Depth Principle, EU-ABWR has a capability to mitigate Design Extension Conditions like Fukushima Accident by using a combination of passive and active systems. Furthermore, a severe accident is mitigated passively without containment venting for at least 72 hours.

Streszczenie:

The extent of automation and autonomy used in general aviation (GA) has been accelerating dramatically. This has huge potential benefits for safety given that 75% of accidents in personal and on-demand GA are due to pilot error. However, an approach to certifying autonomous systems that relies on reversionary modes limits their potential to improve safety. Placing a human pilot in a situation where they are suddenly tasked with flying an airplane in a failed situation, often without sufficient situational awareness, is overly demanding. This, coupled with advancing technology that may not align with a deterministic certification paradigm, creates an opportunity for new approaches to certifying autonomous and highly automated aircraft systems. Unsettled Topics in the General Aviation Autonomy Landscape discusses how these new approaches must account for the multifaceted aviation approach to risk management which has interlocking requirements for airworthiness and operations (including training and airspace integration). If implemented properly, autonomy can take GA safety to the next level while simultaneously increasing the number and variety of aircraft and transportation options they provide.
