Book excerpt: Aircraft mix (i.e., the mix of aircraft with different performance characteristics in a sector) has been repeatedly cited as a complexity factor in en route air traffic control. However, scant attention has been directed to a statistical examination of this relationship. The present study is the third in a series of investigations designed to define, quantify, and assess the validity of aircraft mix as a contributor to traffic complexity. Eighteen 30-minute samples of System Analysis Recording data were collected from the Fort Worth and Atlanta en route centers. Performance and Objective Workload Evaluation Research (POWER) measures and the Aircraft Mix Index (Pfleiderer, 2003a) were computed in 6-minute intervals for each of the 36 samples. Principal Components Analysis of the combined data sets produced four components with eigenvalues>1 accounting for approximately 71% of the variance. The Aircraft Mix Index was most closely associated with Component 1, which was composed of variables generally associated with traffic complexity. These variables were used as predictors against a criterion of controllers' subjective "Complexity" ratings in multiple regression analyses of low- and high-altitude sector samples. The Aircraft Mix Index failed to contribute significantly to the explained variance in the both the low-altitude (R=.69; R2=.47) and high-altitude (R=.57; R2=.33) sector models. In the aggregate, the results suggest that although aircraft mix appears to be associated with traffic complexity, it may not be as influential as other complexity factors in the en route environment.

Book excerpt: The study of workload has a long history, but it was not until a 1977 NATO-sponsored workshop and subsequent book that the concept became a common term used by psychologists and engineers. Since then, research has focused predominately on determining the factors that influence workload, and concurrently, on methods and techniques for measuring it. Of course, workload is a mediational construct that cannot be evaluated or observed directly. Workload assessment methods therefore rely on indirect reflections such as the analysis of objective performance measures, physiological indices, and subjective ratings. Recently, there have been three large-scale reviews of workload research as related to aviation systems. Although each review has a different emphasis and thus reaches different conclusions, there is general agreement on the need for continuing research into pilot workload. The articles in this issue represent a diverse range of contemporary investigations that attest to the belief that there is still room for workload in the panoply of pilot-assessment procedures. The editors hope that these papers further serve to support the continued application of workload research to the operational issues and concerns of the aviation community.

This book was released on 1982 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of equations, definitions, symbols, units of measurement and an equal interval scale providing an equal interval unit rating and measurement method for system evaluation are presented. The objective is to provide a unified approach to the systems engineering evaluation, rating and measurement of a dynamic system. The equations present the hypothsized relationships between system ratings and system measures of performance, work, and load. An equal interval, one-tenth power of ten, scale with ten as the highest rating is introduced for the rating, measuring, and communicating system performance, work, and load factors. These factors are of increasing interest during early R & D system dynamic simulation concept testing and later operational system test and evaluation. (Author).
