Book Description
The experiment was designed to compare three types of aircraft cockpit warning systems: (1) Visual: malfunctions simultaneously activated a master warning light and a specific malfunction indicator light. (2) Visual and tone: malfunctions simultaneously activated an intermittent sweeping tone (through earphones), a master warning light, and a specific malfunction indicator light. (3) Visual and voice: malfunctions simultaneously activated a master warning light, a specific malfunction indicator light, and a voice recording which informed the operator through his earphones of the specific malfunction needing attention. Three groups of 11 university students served as subjects. While responding to a visual, visual-tone, or visual-voice warning system, each subject was also required to find and position, under cross hairs, a series of strategic targets on a strip of rear-projected aerial photographic imagery. No statistically significant differences among the three warning systems were found in the speed of reaction to the master warning light, reaction to the specific-indicator panel, total reaction time, or number of strategic targets found or missed. The results of the study suggest that the addition of either a tone or a voice warning to a visual, master plus specific, malfunction warning system is of questionable value in a 'heads-in' cockpit situation where the visual system can be seen. The data from the experiment do not suggest that a voice warning system has any advantage over a simple aural signal for augmenting a visual system. (Author).

Book Description
The study was designed to create a flight condition that would be sufficiently stressful, and at the same time, require the pilot to direct his attention out of the cockpit for relatively long periods, so that an adequate comparison could be made between voice and tone warning.

Book Description
This is a thorough description of this increasingly important technology, starting from the development of head-up displays (HUDs), particularly specifications and standards and operational problems associated with HUD use. HUD involvement in spatial disorientation and its use in recognizing and recovering from unusual attitudes is discussed. The book summarizes the design criteria including hardware, software, interface and display criteria. It goes on to outline flight tasks to be used for evaluating HUDs and discusses the impact of HUDs on flight training. Recent work indicates that a HUD may allow a significant reduction in the time required to train a pilot on a particular aircraft, even considering non-HUD-related tasks. The author concludes with a review of unresolved HUD issues and recommendations for further research and provides an impressive bibliography, glossary and index. Within the military aviation sector the book will be of use to industry, research agencies, test pilot schools and air force training establishments. In the civil area regulatory authorities, airlines and industry will also have an increasing interest.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
