Aeromedical aspects of melatonin : an overview by Donald C Sanders( )

3 editions published in 1998 in English and held by 368 WorldCat member libraries worldwide

Melatonin, a pineal hormone present in the blood of humans and other species, has a distinct diurnal variation in its biosynthesis and, therefore, in its concentration. This variation has suggested the possibility of a regulatory function in day/night dependent physiological processes, such as sleep, and has led scientists to explore the effects of administered melatonin on the modulation of circadian rhythms. For the self-treatment of sleep disorders and other benefits, melatonin usage has been extolled to the extent that 20 million new consumers were added to the U.S. retail market in 1995. Its principal aeromedical application has been in the experimental treatment of jet lag effects. For aircraft passengers, melatonin administration at destination-bedtime appears to improve sleep quality and to decrease the time required to reestablish normal circadian rhythms. For international aircrews, who travel through multiple time zones without time to adapt to new environments, taking melatonin prior to arriving home may further impair already disturbed circadian rhythms. Its use to adjust to shiftwork changes by air traffic controllers, aircraft maintenance workers, and support personnel is even more controversial. Limited studies suggest that giving this hormone to shift workers should be done only under controlled conditions and that taking it at the wrong time may actually impair job performance. Because of its possible interaction with certain medications and the changes in its concentrations observed in some clinical conditions, the practitioner must exercise caution during the medical certification of airmen. The variations in the concentration of melatonin can be effectively determined by radioimmunoassay, high-performance liquid chromatography, and gas chromatography-mass spectroscopy analytical techniques
Recovery of the FAA air traffic control specialist workforce, 1981-1992( )

3 editions published in 1998 in English and held by 368 WorldCat member libraries worldwide

The Federal Aviation Administration was confronted in 1981 with the challenge of rebuilding its core, technical, and highly-trained air traffic control specialist (ATCS) workforce following the PATCO strike. From late 1981 through mid-1992, the FAA rebuilt this critical workforce through a large-scale testing, screening and training program. By mid-1992, recovery of the controller workforce was complete, and it was no longer necessary for the FAA to conduct a large-scale hiring program. The six papers presented in this report represent the first major retrospective analysis of the complete data set describing the recovery of the FAA's en route and terminal ATCS workforce following the 1981 controller strike. The first paper describes the personnel processes, focusing on recruitment and hiring programs for the en route and terminal options. The second paper presents a detailed description of the aptitude test battery used to evaluate over 400,000 applicants between 1981 and 1992. The third paper offers a definitive statistical portrait of the FAA Academy Screening programs as predictors of field training outcomes. On-the-job training (OJT) programs in en route and terminal facilities are described in the fourth paper. These four papers, taken together, provide a definitive description of the processes used to recruit, test, screen, and train persons for the ATCS occupation between 1981 and 1992. The fifth paper draws on FAA organizational survey data to describe controller perceptions of the organizational climate in which the workforce recovery occurred. The sixth paper analyzes current controller workforce demographics and technological trends in air traffic control to identify potential areas of future research

Flight attendant fatigue by Joy O Banks( )

1 edition published in 2009 in English and held by 235 WorldCat member libraries worldwide

In 2008, Congress directed the Civil Aerospace Medical Institute (CAMI) to conduct follow-on studies of six recommendation areas noted in an integrated report by the National Aeronautics and Space Administration (NASA) and CAMI regarding flight attendant fatigue. The report concluded that some degree of fatigue-related performance affects were likely under current prescriptive rules. Internationally, fatigue risk is managed almost solely through prescriptive rules based on the maximum hours of work and minimum hours of rest. Traditional prescriptive rules, however, have limited applications to round-the-clock operations, often excluding fatigue-contributing factors such as time zone transitions, layover and recovery, time of day, and circadian rhythms (Cabon et al, 2009). Prescriptive rules directly affect crew scheduling and are critical to operator viability; however, due to economic recession, operators are routinely scheduling up to the regulation limits, which could result in an increased likelihood of fatigue and fatigue-related mishaps (Nesthus, Schroeder, Connors, et al., 2007). In the present study, we obtained regulations (n=38) and collective bargaining agreements (CBA) (n=13) regarding flight attendant duty time and rest from International Civil Aviation Organization (ICAO) member states using several resources: Civil Aviation Authority Web sites, an international cabin safety symposium, Web-based ICAO information exchange, and FAA international field offices and aviation safety inspectors. We analyzed each regulation and CBA to identify duty time and rest rules related to working hour limits, sleep and rest requirements, circadian rhythms, and other factors. When comparing the United States (U.S.) maximum hours of work and minimum hours of rest with other countries, we concluded that U.S. prescriptive rules are among the least restrictive, representing a greater than typical risk for fatigue related incidents
Role of metabolites in aviation forensic toxicology : final report by Arvind K Chaturvedi( )

2 editions published in 1995 in English and held by 227 WorldCat member libraries worldwide

In aviation accident investigations, specimens from fatal aircraft victims are analyzed for drugs. Their presence indicates exposure to drugs and suggests possible associated medical conditions for which they might have been taken. As drugs are mostly present in therapeutic to subtherapeutic levels in aviation forensic toxicology cases, determination of parent drugs and their metabolites in multi specimens is of significance. Although chemically reactive metabolites are difficult to detect, physiologically active and inactive metabolites can be analyzed. Selective and sensitive techniques are available, but unavailability of metabolite reference standards, endogenous substance interference, and low tissue metabolite levels limit the analyses. However, the majority of primary metabolites can be effectively characterized/quantitated. Demonstrating the presence of drug (e.g., terfenadine, cocaine, THC) metabolites provides a compelling evidence for exposure to the parent drug and facilitates interpretation of results, particularly when the metabolites are active. Such analyses are not as helpful if the metabolites are also available as drugs (e.g., diazepam, temazepam, oxazepam)
Use of personality assessment measures in the selection of air traffic control specialists( )

1 edition published in 2003 in English and held by 225 WorldCat member libraries worldwide

Three studies illustrated the uses of personality assessment methods for selection of Federal Aviation Administration (FAA) air traffic control specialists (ATCSs). Study 1, using a select-out approach to the problems of screen, compared the Sixteen Personality Factor Questionnaire (16 PF) results with NEO Personality Inventory-Revised (NEO PI-R) results from 122 student ATCS participants. Results suggest that the current approach to personality assessment during the initial medical examination focuses primarily on the extent to which the applicant reports symptoms consistent with neurotic, inefficient, and perhaps argumentative characteristics. The remaining two studies consider select-in strategies looking at the psychometric issues of reliability, specificity, and validity. Study 2 examined the NEO PI-R along with the Experiences Questionnaire (EQ) subtests of the Air Traffic-Selection and Training (AT-SAT) battery scores

DNA-based detection of ethanol-producing microorganisms in postmortem blood and tissues by polymerase chain reaction( Book )

2 editions published in 2000 in English and held by 170 WorldCat member libraries worldwide

Forensic investigation of fatal aircraft accidents usually includes the analysis of biological samples for ethanol to establish if alcohol intoxication is a factor in the accidents. The quantitative aspects of ethanol are often complicated by postmortem putrefactive changes, leading to microbial fermentation-mediated production of alcohol and its subsequent redistribution. Without establishing the ethanol origin (antemortem consumption or postmortem production), a precise interpretation of the alcohol analytical results remains a challenge. Therefore, a DNA-based assay was developed using the polymerase chain reaction and microbial DNA primers designed for identifying 3 commonly encountered ethanol-producing microorganisms- Candialbicans, Proteus vulgaris, and Escherichia coli. The present study focused on examining the applicability of the microbial DNA primers in establishing the existence of postmortem alcohol in samples. The results suggested that species- specific primers could be employed to identify ethanol-producing microorganisms in forensic samples without requiring bacterial cultivation. Continued studies are warranted to define additional primer sequences that are distinctive for ethanol-producing microorganisms
Performance of a continuous flow passenger oxygen mask at an altitude of 40,000 feet by Robert P Garner( Book )

3 editions published in 1996 in English and held by 169 WorldCat member libraries worldwide

A redesigned continuous flow passenger oxygen mask was tested for its ability to deliver an adequate supply of oxygen at an altitude of 40,000 feet above sea level. Four male subjects participated in the study. Blood oxygen saturation (SaO2) baseline levels for hypoxic exposure were established for each subject. Immediately prior to high altitude exposure, subjects prebreathed 100% oxygen for two hours through a pressure demand type mask. The hypobaric chamber was then decompressed to a simulated altitude of 35,000 feet. Subjects switched to the passenger oxygen mask. The initial oxygen flow rate to the passenger mask came from manufacturer production performance test data. Once heart and respiratory rates and SaO2 level stabilized, chamber altitude was increased to 40,000 feet. Descent to ground level was performed in steps of 5,000 feet with SaO2 levels being established for each altitude and recommended oxygen flow. Subjects remained at each test altitude for a minimum of three minutes or until SaO2 levels stabilized. At no point during the testing did SaO2 levels approach baseline levels for hypoxic exposure. This mask design would appear to offer protection from hypoxia resulting from altitude exposure up to 40,000 feet
The effects of video game experience on computer-based air traffic controller specialist, air traffic scenario test scores by Willie C Young( Book )

2 editions published in 1997 in English and held by 169 WorldCat member libraries worldwide

The FAA is currently using the Air Traffic Scenario Test (ATST) as a major portion of its selection process. Because the ATST is a PC based application with a strong resemblance to a video game, concern has been raised that prior video game experience might have a moderating effect on scores. Much of the previous research in this area is associated with topics such as the moderating effects of prior computer experience on scores earned on computerized versions of traditional achievement or power tests, and the effects of practice on video games on individual difference tests for constructs such as spatial ability. The effects of computer or video game experience on work sample scores have not been systematically investigated. The purpose of this study was to evaluate the incremental validity of prior video game experience over that of general aptitude as a predictor of work sample test scores. The Computer Use Survey was administered to 404 air traffic control students who entered the FAA ATCS Nonradar Screen. The resultant responses from this survey related to video games were summed and averaged to create the predictor (VIDEO). Three criterion measures derived from the ATST, (ATSAFE, ARVDELAY, HNDDELAY) were regressed on the cognitive aptitude measure that serves as the initial selection screening test and the predictor (VIDEO). Self-reported experience on video games was found to be significantly related to ARVDELAY and HNDDELAY, accounting for an additional 3.6% of the variance in ARVDELAY, and accounting for an additional 9% of the variance in HNDDELAY. The results suggested that those persons with video game experience were more efficient at hand-offs and routing aircraft. Future research is recommended to investigate the effect of prior video game experience on learning curves and strategies used in the work sample test
Effects of simulated general aviation altitude hypoxia on smokers and nonsmokers( Book )

4 editions published in 1997 in English and held by 169 WorldCat member libraries worldwide

General aviation pilots are permitted to fly without the use of supplemental oxygen up to an altitude of 12,500 ft. However, hypoxia occurs at altitudes under 12,500 ft. Personal lifestyle, physical conditioning, and illness can interact with hypoxia to affect performance. This study evaluated physiological and cognitive performance of smokers and nonsmokers during sessions of mild hypoxia. Nine male smokers and 9 nonsmokers performed the Multi-Attribute Task Battery (MATB) while breathing oxygen mixtures that simulated sea level, 5,000 ft., 8,000 ft., and 12,500 ft. altitude conditions. Four physiological measures: transcutaneous partial pressures of oxygen and carbon dioxide (P(tc)O2 and P(tc)CO2), heart rate (HR), and oxyhemoglobin saturation (SaO2), demonstrated significant trends across the simulated altitude conditions and for some measures, between groups. Results of the physiological measures obtained, confirmed the study's targeted levels of hypoxia. Smokers exhibited elevated HR and lower P(tc)CO2 values, compared with nonsmokers. Elevated HR is consistent with nicotine effects. Reduced P(tc)CO2 values may indicate greater hyperventilation among the smokers. Smokers may have experienced a reduction of peripheral vision and their ability to visually monitor several tasks simultaneously
Age and attitudes in the air traffic control specialist workforce : an initial assessment by Richard Thompson( Book )

3 editions published in 2000 in English and held by 168 WorldCat member libraries worldwide

The present study examines the relationships between air traffic control specialist age, after covarying job tenure, with perceptions of job satisfaction, quality of work life, organizational commitment, and supervisory fairness. The presence of a relationship and the shape of the relationship are examined for four categories of controllers based on air traffic option or work setting (i.e., working in an enroute, flight service stations, Level 1 to 3 or level 4 or 5 terminal (towers and tracons)). The results suggest that there is a small linear relationship between age and attitudes. Similar patterns have been found in age research in other work settings. There are some differences in the shape of the age function based on air traffic option; these differences account for minimal variance. It may be fruitful to develop a more focused study where age is measured as a continuous variable instead of using age categories, which may have masked some differences found in past research. In addition, future research may consider examining the age and attitudes relationships using international controllers to determine if there are cultural differences in the relationships found

The Influence of ergonomic interventions on employee stress and physical symptoms by Kurt M Joseph( Book )

4 editions published in 1999 in English and held by 167 WorldCat member libraries worldwide

A recent report by the GAO (1997) indicates that private sector employers spend as much as $20 billion annually for employee injuries and illnesses due to musculoskeletal disorders (MSDs). While the etiologic mechanisms are poorly understood, there is increasing evidence that psychosocial risk factors related to the job and work environment play a role in the development of work-related MSDs. A longitudinal study was completed to determine the influence of six psychosocial factors and two cost-effective ergonomics interventions on physical discomfort and stress scores reported by employees within a Federal Aviation Administration organization. The results of the study revealed that stress scores decreased significantly across time. However, physical symptom scores did not change across time, nor were they affected by the ergonomic interventions. Two psychosocial factors provided significant and reliable adjustments to stress and physical discomfort scores
Where the safety rubber meets the shop floor : a confirmatory model of management influence on workplace safety by Richard Thompson( Book )

3 editions published in 1997 in English and held by 167 WorldCat member libraries worldwide

The role of management in establishing a safe work environment remains a topic that receives less attention in the literature than it deserves. There is little empirical evidence that validates the important role management plays in establishing a climate that sustains safe job behaviors. This paper presents a model that links management support, organizational climate, and self-reported safety outcomes
A new approach to aeronautical decision-making : the expertise method by Janeen A Kochan( Book )

4 editions published in 1997 in English and held by 166 WorldCat member libraries worldwide

Four studies of pilot decision-making were conducted to formulate a general model of the expert pilot that might be applied to novice pilots in order to increase their decision-making skills and reduce their risk of accident involvement. This set of studies began with a series of unstructured interviews of pilots to identify and compile characteristics of the expert pilot. Each succeeding study, then, became more structured in its approach as the characteristics of an expert pilot were more closely defined. From structured interviews conducted as part of the second study, a preliminary definition was obtained that stressed motivation, confidence, superior learning and performance skills, and an intuitive decision-making style. The third study evaluated these characteristics as they were possessed by pilots of three types of relatively high-performance general aviation aircraft. In the final study, experienced pilots were presented with a plausible general aviation flight scenario using a verbal protocol methodology. The responses of the pilots to this table-top simulation were recorded and analyzed. These data suggest that, when compared to competent pilots, expert pilots tend to (1) seek more quality information in a mote timely manner; (2) make more progressive decisions to solve problems; and, (3) communicate more readily with all available resources
Controlled flight into terrain : a study of pilot perspectives in Alaska by Larry L Bailey( Book )

4 editions published in 2000 in English and held by 166 WorldCat member libraries worldwide

This report presents the results of a survey designed to identify pilot and organizational risk factors of having a controlled flight into terrain (CFIT) accident in Alaska. The population consisted of commercial (passenger and freight) Alaskan pilots who operated under Parts 135, 133, 125 and/or 121 Federal Aviation Regulations (FARs). A 103-item questionnaire was developed covering the following domains: 1. organizational influences, 2. unsafe supervision, 3. preconditions for unsafe pilot acts, and 4. unsafe pilot acts. Pilots were pre-coded into one of two groups based on whether their current employer had experienced a CFIT accident within a five-year period (1992-1997). Response rates across both groups were 20% and although lower than desired, it was not unusual for surveys of this nature. Survey results revealed that having to fly in marginal weather conditions was a common experience for all respondents. However, pilots who worked for companies who had a CFIT accident rated their company's safety climate and practices significantly lower than pilots who worked for CFIT accident free companies. Based on the survey results and considering the findings of the Aviation Safety in Alaska report (National Transportation Safety Board, 1995) the following recommendations were developed to reduce the number of CFIT accidents in Alaska: 1. increase pilot awareness of CFIT safety-related issues, 2. improve company safety culture, 3. improve pilot training in the environment in which they commonly fly, 4. improve weather briefings, and 5. eliminate pressure to complete a flight
A unique contact lens-related airline aircraft accident by Van B Nakagawara( Book )

3 editions published in 2000 in English and held by 166 WorldCat member libraries worldwide

The use of contact lenses to satisfy the distant visual acuity requirements for obtaining a civil airman medical certificate has been permitted since 1976. According to the Federal Aviation Administration's "Guide for Aviation Medical Examiners," the use of monovision contact lenses is not considered acceptable for aviation duties. An aviation accident involving the use of monovision contact lenses will be reviewed. A case report is presented utilizing information from a National Transportation Safety Board (NTSB) aircraft accident report (NTSB/AAR-97/03) of a nonfatal scheduled airline accident. Past studies that examined the use of contact lenses in the aviation environment are reviewed. On October 19, 1996, a McDonnell Douglas MD-88 aircraft, Delta Airlines Flight 554, was substantially damaged in an undershoot approach while landing at LaGuardia Airport, Flushing, NY. Weather observations indicated a broken cloud layer at 800 feet, visibility between 1/2 and 1 mile in heavy rain and fog or mist, and easterly winds at 12 to 14 knots. The approach was over water to Runway 13 and the flight crew transitioned to visual references just above the decision height. As the airplane continued to descend, it struck an approach light structure and the end of the runway deck, shearing off the main landing gear and slid 2,700 feet down the runway. During an emergency evacuation, 3 passengers received minor injuries. The NTSB determined that the probable cause of this accident was the inability of the pilot to overcome his misperception of the airplane's position relative to the runway, due to the use of monovision contact lenses. The adverse effects of wearing contact lenses in the aviation environment are discussed. Research is recommended to better understand the effects of environmental conditions on monovision to validate the current policy on such corrections
