GPS user-interface design problems by Kevin W Williams( Book )

7 editions published in 1999 in English and held by 237 WorldCat member libraries worldwide

This paper is a review of human factors problems associated with the user-interface design of a set of Global Positioning System (GPS) receivers, certified for use in aircraft for instrument non-precision approaches. The paper focuses on design problems associated with the interfaces and specific inconsistencies across the set of interfaces that could cause confusion or errors during operation. Some specific problems addressed involve the layout and design of knobs and buttons; control labeling inconsistencies across units; the placement and use of warnings; feedback, or the lack thereof; and the integration of specific flying tasks while using the receivers. Recommendations for solving some of the problems are provided, as well as suggestions to the FAA, GPS manufacturers, and pilots regarding the future development and use of these products
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 208 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
The use of task-specific lenses by presbyopic air traffic controllers at the en route radar console by Van B Nakagawara( Book )

5 editions published between 1996 and 1997 in English and held by 205 WorldCat member libraries worldwide

The configuration of the radar console to control aircraft traffic has similar features to a visual display terminal (VDT) work station. Task-specific lenses have been found in clinical studies to reduce visual symptoms while working at the VDT. The American Optical Corporation TruVision Technica, a task-specific lens design, was evaluated to see if visual benefits from such a lens could be transferred from the VDT environment to the radar console work environment. Presbyopic Air Traffic Control Specialists (ATCSs) at the Houston Air Route Traffic Control Center were fitted with two prescription spectacles, using their current and Technica lens designs, in similar ophthalmic frames. Each ATCS used both lens designs at the radar console and provided subjective evaluations of their appropriateness in that environment. Thirteen (13) subjects (45.6 plus or minus 5.9 years of age, range 36-55 years) completed the study. Subjects who used larger near viewing area (single vision and executive) lens designs generally preferred their current lens design. The Technica was preferred by mature presbyopes (add power of greater than or equal to 1.25 diopters) and those using smaller near viewing area (FT-25, FT-28 and general progressive addition) lens designs. The primary complaints reported by ATCSs with the Technica were peripheral distortion and limited field of view. Task-specific lens designs are an alternative for presbyopic ATCS who work at a radar console. However, distortion and limited field of view from the lens may require prolonged adaptation times before such designs are acceptable to ATCS on the job, especially for those accustomed to lens designs with larger viewing areas
Performance demonstrations of zinc sulfide and strontium aluminate photoluminescent floor proximity escape path marking systems by Garnet A McLean( Book )

2 editions published in 1998 in English and held by 203 WorldCat member libraries worldwide

Transport category aircraft are required by 14 CFR 25.812 to have emergency lighting systems, including floor proximity marking systems. Typical floor proximity marking systems installed on transport category aircraft have been primarily comprised of incandescent luminaries spaced at intervals on the floor, or mounted on the seat assemblies, along the aisle. The requirement for electricity to power these systems has made them vulnerable to a variety of problems, including battery and wiring failures, burned-out light bulbs, and physical disruption caused by vibration, passenger traffic, galley cart strikes, and hull breakage in accidents. Attempts to overcome these problems have led to the proposal that non-electric photoluminescent materials be used in the construction of floor proximity marking systems. To assess the viability of this proposal, performance demonstrations of systems made with such materials were conducted. It was found that strontium aluminate photoluminescent marking systems can be effective in providing the guidance for egress that floor proximity marking systems are intended to achieve; in contrast, zinc sulfide materials were found to be ineffective
A flexible cabin simulator by Jeffrey H Marcus( Book )

2 editions published in 1997 in English and held by 201 WorldCat member libraries worldwide

Experimental research on issues related to emergency evacuation of a passenger aircraft cabin have tended to use existing aircraft cabins. While a great deal of useful information has been collected, these facilities have limited capabilities to be configured to investigate new or unusual cabin arrangements. A concept design for a flexible cabin simulator has been completed and is described. The proposed facility can simulate any aircraft cabin from a small, commuter category aircraft through a multi-aisle, multi-deck mega-jumbo transport. The simulator allows full flexibility in terms of exit type and placement, location and design of interior monuments, and the size and layout of the passenger cabin. Experimental control is possible of interior and exterior illumination levels, the presence of vision obscuring smoke, and the door sill height when using evacuation slides. Built from modular sections, it might be used in the future to investigate new and unusual cabin designs, such as the flying wing. The proposed simulator is described to illustrate its versatility. The associated building and project costs are also discussed
Personality characteristics of pre/post-strike air traffic control applicants by David J Schroeder( Book )

3 editions published in 1997 in English and held by 201 WorldCat member libraries worldwide

The 16 Personality Factors (16PF) test has been routinely administered to personnel applying for Air Traffic Control Specialist (ATCS) positions within the Federal Aviation Administration for more than 3 decades. This study was designed to assess the relationship between personality characteristics of a group of post-strike applicants (1984) with data gathered in the late 1960s to early 1970s (Karson and O'Dell, 1974). Additionally, the comparisons provide a baseline with which to assess characteristics of the new controllers who will start to enter the workforce as the post-strike workforce begins to retire following the year 2000. Outcomes were consistent with previous findings, in revealing that female and male ATCS applicants are brighter than the average individual. When compared with the general population norms, the applicant groups are less anxious, report higher self-discipline, and are more emotionally stable. They are also more self-reliant and assertive. These characteristics appear to be ideally suited for applicants to an occupation that requires quick decision-making and calm, thoughtful responses during emergencies
The role of memory in air traffic control by Scott D Gronlund( Book )

3 editions published in 1997 in English and held by 200 WorldCat member libraries worldwide

We tested air traffic controllers currently serving as instructors and tried to manipulate their memory for various aircraft flight data. In Experiment 1, the amount of control exercised (the number of control actions or communications) had little effect on memory for flight data, although we did find excellent memory for the position of aircraft on the radar display. We argued that this was the basis for the mental representation of the aircraft in the sector and may serve as the foundation for situation awareness. In Experiment 2, neither the type of control exercised nor the importance of the aircraft in the scenario consistently affected memory. We considered several reasons why we were unable to manipulate memory for flight data, including how important memory is to successful task performance and whether we tapped the relevant characteristics of the situation. Resolution of these issues will contribute to improved techniques that assess situation awareness from memory performance
A new approach to aeronautical decision-making the expertise method by Janeen Adrion Kochlan( Book )

4 editions published in 1997 in English and held by 200 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
Baseline assessment of the National Association of Air Traffic Specialists/Federal Aviation Administration partnership by Richard Thompson( Book )

3 editions published in 1997 in English and held by 200 WorldCat member libraries worldwide

The Federal Aviation Administration's (FAA's) Flight Service Station (FSS) management and the leadership of the National Association of Air Traffic Specialists (NAATS) requested a baseline assessment of organizational climate prior to full implementation of NAATS/FAA Partnership (NFP) teams. The stated purpose of the NFP teams is to increase employee empowerment and improve decision-making and coordination within the organization
Designing selection tests for the future national airspace system architecture by Dana Broach( Book )

3 editions published in 1997 in English and held by 199 WorldCat member libraries worldwide

Empirical data describing the mix of human abilities required to operate and maintain the future National Airspace System (NAS) architecture are presently lacking. A research program is proposed to develop the scientific tools and collect data to describe and assess the mix of abilities likely to be required of future Federal Aviation Administration air traffic control specialists, electronics technicians, and transportation system specialists. The first phase of the proposed research program is to develop a baseline profile describing the skills, abilities, and knowledge required to use, operate, and maintain the current NAS architecture. The second phase of the program is to develop and apply scientific tools to identify changes in personnel selection requirements in parallel with air traffic control and maintenance systems development. The third step in the research program is to develop, validate, and deliver new personnel selection technologies to reflect the human ability and performance needs of the future NAS architecture. The research program is designed to provide agency managers with the selection tools needed to manage personnel costs, inevitable generational change in the technical workforces, and technological innovation in air traffic control and maintenance systems
Effects of simulated general aviation altitude hypoxia on smokers and nonsmokers( Book )

4 editions published in 1997 in English and held by 199 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
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 199 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
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 199 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
Inflight medical care an update by Charles A DeJohn( Book )

3 editions published in 1997 in English and held by 199 WorldCat member libraries worldwide

A major concern in aviation medicine is the cabin inflight emergency that may result in the diversion of a flight. At the present time there is no convenient way to monitor the incidence of inflight medical emergencies because airline companies are not regularly required to report medical emergencies or resulting diversions. A survey of one major US airline revealed that one out of every one million passengers may be deplaned by an unscheduled landing because of a life-threatening medical emergency. During a two-year FAA survey of US domestic flights there were 2,322 inflight medical emergencies, averaging approximately three per day, which resulted in an annual diversion rate of approximately 9%. In a 1989 study, inflight emergencies among arriving passengers at the Los Angeles International airport were analyzed. During the six-month period of the investigation 0.003% of 8.5 million passengers developed symptoms in flight that required follow-up assistance on the ground, and 10% of these passengers required hospitalization. A survey of the status of inflight medical care aboard domestic US air carriers was undertaken to determine the impact of current changes in the airline industry. Information for the years 1990 to 1993 was obtained from two airlines and two inflight medical care delivery companies, representing a total of nine major US Part 121 air carriers. This sample accounted for approximately 65% of US domestic air carrier activity for the period 1990 to 1993. The information was reviewed to determine which category of inflight medical emergency occurred most frequently and which category accounted for the greatest number of diversions. The trend in the frequency of diversions for medical reasons was also assessed. The impact of inflight medical advice was then evaluated by comparing the number of diversions that resulted in hospitalizations to the numb
Recovery of the FAA air traffic control specialist workforce, 1981-1992( Book )

3 editions published in 1998 in English and held by 185 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
Aeromedical aspects of melatonin an overview by Donald C Sanders( Book )

3 editions published in 1998 in English and held by 173 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

An investigation of the relationship between chronological age and indicators of job performance for incumbent air traffic control specialists by Michael C Heil( Book )

1 edition published in 1999 in English and held by 1 WorldCat member library worldwide

Researchers have explored the issue of air traffic control specialist (ATCS) age and performance many times over the past few decades. These researchers have consistently found a negative relationship between the age of Air ATCSs and both training success and ratings of job performance. A recent study (Heil, 1999) found a curvilinear relationship between ATCS age and performance on a computerized simulation of air traffic situations, with performance decreasing for people in their mid 40s. Some researchers (Heil, 1999; Schroeder, Broach, & Farmer, 1997) have speculated that these relationships maybe due to a decline in cognitive ability with age. The purpose of the current study is to investigate the relationship between age and performance on tests of cognitive ability for incumbent ATCSs. As part of a concurrent validation study, 1083 incumbent ATCSs from 12 enroute centers took a newly developed air traffic control selection test. The tests included in the 6 hour battery were developed to measure the knowledge, skills, abilities, and other characteristics (KSAOs) relevant to the ATCS job. Some of the KSAOs measured by the battery include: ability to prioritize, situational awareness, planning, execution, thinking ahead, short-term memory, reasoning, decisiveness, concentration, perceptual speed and accuracy, mathematical reasoning, and ability to deal with dynamic visual movement. The relationship between current age and performance on these cognitive tests was compared using regression analysis and analysis of variance procedures. The results of these analyses suggest some age-related decline in those cognitive abilities that are most important to successful job performance
