Available in PDF, EPUB and Kindle. Book excerpt: Pilot rating scales and their use in assessing aircraft handling qualities are reviewed historically, and objections that have been raised to limitations of earlier scales are considered in the development of a revised scale. Terminology used in the evaluation of handling qualities is reviewed and new definitions are proposed to improve communication and international understanding. Of particular significance is the new definition of handling qualities, which emphasizes the importance of factors that influence the selection of a rating other than stability and control characteristics. The experimental use of pilot rating is discussed in detail, with special attention devoted to (1) clarifying the difference between mission and task, (2) identifying what the rating applies to, (3) considering the pilot's assessment criteria, and (4) defining the simulation situation. The important elements of the report are then summarized in a suggested 'Briefing Guide, ' designed for guidance in planning and executing handling qualities experiments.

This book was released on 1968 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although rating scales of varied forms have been widely used to estimate and evaluate handling qualities over the past decade, a number of deficiencies in both method and data base have been apparent. The investigation was aimed at overcoming many of these deficiencies by attempting to resolve the difficulties experienced with rating scales themselves, and by extending and adding to already existing relationships between ratings and pilot/vehicle system parameters. Rating scales have come under increasing criticism for problems such as wording ambiguity, the dual mission character of some scales, the nonuniformity in the distribution of descriptors across the scale, and the misuse of scales which has occurred when ratings have been averaged. Psychometric methods provide an approach to these problems, and were used to scale several phrases descriptive of vehicle handling qualities. Thus, quantitative characteristics were derived for contemporary scales through the use of the Method of Successive Intervals. An experiment was conducted which added to available data relating Cooper ratings and pilot/vehicle parameters, and which also tested some potential alternate scale candidates. The correlation results indicate that ratings are probably based on performance and the degree of difficulty experienced in maintaining the performance. The difficulty is most easily represented by the pilot equalization required and the vehicle stick characteristics. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The report discusses the assessment of handling quality characteristics Since handling qualities deal with the teamed product, both elements -- pilot and airplane -- must be represented in order to assess handling qualities. One cannot simply examine the time history of the response of an airplane to a particular control input and assess, in an intuitive engineering sense, whether such a response will be good or bad when employed by a pilot in a mission. Rather, it is necessary to examine the suitability of the pilot-airplane combination for accomplishing the mission. Some of the important factors which affect the quality or applicability of pilot assessment of the handling qualities of airborne vehicles are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the development and rationale for a new approach to pilot proficiency measure ment in operational flight trainers. It is based on a 'natural pilot model' that identifies three criteria as being of prime importance to the understanding and measurement of pilot perform ance: consistency of system performance, human adaptability, and least effort in skilled performance. By means of these criteria - which arose from an effort to apply the servo-mechanism theory of skilled performance to the study of pilot proficiency - the investigators believe that the traditional impediments to valid measure ment will be removed; and that the characteristics that most crucially differentiate the good from the poor pilot will be measured. Ways of quantifying these criteria and the implications to training and further research are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in aircraft handling qualities indicate the possibility that a small number of physical dimensions can be used for handling qualities quantification. Several candidate metrics for handling qualities now exist which form a portion of the set required. An exploratory study was conducted to evaluate the use of multivariate analysis techniques for identification of the necessary physical dimensions of handling qualities. It is concluded that the Cooper-Harper scale can be considered a direction in the space defined by the first few principal components of the experimental variance-covariance matrix. A simulation experiment is proposed which should permit development of a set of nonadjectival rating scales which will complement the Cooper-Harper scale, reduce the variability of pilot rating data, and better support the flight test identification of handling deficiencies.

Download or read book Evaluation and Estimation of Handling Qualities Via Statistical Modeling of Pilot Response Data written by and published by . This book was released on 1991 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a research project which measured pilot response to seven control systems simulating different handling qualities, quantitatively evaluated and compared the systems based on these measurements, and compared the quantitative system evaluation based on measured pilot performance with a qualitative evaluation using the Cooper-Harper technique. The objective of the project is implementation of a methodology for system evaluation via pilot performance to complement the current evaluation technique based on subjective ratings by test pilots. Pilot performance is determined through analysis of objective dynamic measurements of pilot response typical of flight test environments. In short, the methodology specifies a general approach for condensing the typically huge mound of measured test data accumulated during flight simulation experiments into meaningful quantities for system evaluation. The key element in the methodology is statistical modeling of a law for pilot control. Statistical modeling of pilot control provides an assessment of pilot performance in terms of standard statistical estimation parameters. The methodology requires that this control model be used to compute control input in a closed loop tracking task; the accuracy of the control model in performing this task is an important measure of pilot performance relevant to system evaluation. In addition, these parameters computed from the dynamic measurements of pilot performance are shown to enhance understanding of the aspects of the handling qualities underlying subjective rating techniques such as Cooper-Harper.
Download or read book Criteria for Low Speed Longitudinal Handling Qualities written by H.A. Mooij and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-fl ight simulation experiments performed in 1967 with a variable-stabil ity aircraft during the author's stay at Princeton University, motivated the study of handl ing characteristics of future transport aircraft with closed-loop fl ight control systems. In 1972, the first experiment took place at the National Aerospace Laboratory NLR, using one of its research aircraft. In anticipation of expected developments in (digital) fl ight control technology, the research programme following the first experiments was aimed at the establ ishment of quantitative handl ing qual ities criteria. An appreciable part of that programme has been sponsored by the Netherlands Agency for Aerospace Programs (Nederlands Instituut voor VI iegtuigontwikkel ing en Ruimtevaart) and the Department of Civil Aviation of the Netherlands (Rijksluchtvaartdienst). In 1981, a thorough review of the extensive and valuable data gathered was started. The result, presented in this book, was also included in the author's thesis for a Ph.D. degree of the Delft University of Technology. To introduce the reader to the multi-discipl inary field of handl ing qual ities research, introductory chapters are presented on longitudinal aircraft dynamics, closed-loop fl ight control systems using non-mechanical signal transmission, human pilot dynamics, hand I ing qual ities assessment techniques, and the present status of handl ing qual ity criteria.
