The study, by the U.S. Federal Aviation Administration (FAA) Civil Aeromedical Institute (CAMI) in Oklahoma City, Oklahoma, found that one such personal computer (PC)–based simulator “can be a useful and economical tool for examining experimental questions involving general aviation pilotage,” despite some minor drawbacks. Although this study examined the uses of PCs and standard software for g...

Listeners’ skill at identifying five target languages from short samples and discriminating the targets among a set of other languages was tested. Subjects in two groups, US and French, were generally quite successful in identification. Individual variation is poorly explained by degree of prior casual exposure to the target languages or academic linguistic training. Linguistic training does pr...

The NASA Aviation Safety Program (AvSP) has defined several products that will potentially modify airline and/or ATC operations, enhance aircraft systems, and improve the identification of potential hazardous situations within the National Airspace System (NAS). Consequently, there is a need to develop methods for evaluating the potential safety benefit of each of these intervention products so...

Through our four years experiments on students' Scrum based agile software development (ASD) process, we have gained deep understanding into the human factors of agile methodology. We designed an agile project management tool - the HASE collaboration development platform to support more than 400 students self-organized into 80 teams to practice ASD. In this thesis, Based on our experiments, sim...

Approximately eight percent of human males (and a fraction of one percent of females) in a given population of aircrew training applicants will have some degree of color insensitivity: that is, be unable to discriminate between certain shades of a color and white, or, between shades of colors, or even between certain colors. The insensitivity may range from mild to complete, and should not, in ...

Cholesterol is a waxy substance found among fats in the bloodstream and in all cells throughout the body. Cholesterol is required for the body’s normal formation of cell membranes, other body tissues and some hormones. The liver typically produces as much cholesterol as the body needs — about 1,000 milligrams a day. Individuals consume additional cholesterol when they eat foods derived from ani...

The convergent scientific disciplines of human factors and ergonomics (HF/E) are primarily concerned with how human beings interact with technological systems in all their various forms. HF/E has focused particularly on ways of improving the quality and safety of human work. Contemporary HF/E encompasses the imagination, design, fabrication, operation, maintenance, and decommissioning of all te...

A 1992 U.S. report found that the injury rate per 100 full-time workers for U.S. airline employees was 13.0 percent, compared with [a] private-sector average of 8.6 percent, “an indication of the hazardous nature of the airline industry.” During the period between 1978 and 1988, the report said there was no significant change in the rate. The report, which examined 1988 statistical data on occu...
