Available in PDF, EPUB and Kindle. Book excerpt: Flight tests were conducted and techniques developed for evaluating the handling qualities of an aircraft using combat-oriented air-to-air tracking maneuvers. This technique involves precision tracking of a target aircraft through wind-up turn and constant angle of attack turn maneuvers. The gun camera film of these maneuvers was analyzed for characteristic pipper motion relative to the target and tracking errors in the longitudinal and lateral-directional axes. Correlation of these data with pilot comments provides a means of evaluating the acceptability of aircraft stability and handling qualities in the maneuver environment for which the aircraft was designed. The TWeaD II F-4, which incorporated a variable gain control augmentation system (CAS), was used in the flight development of these tracking test techniques. With the CAS, three levels of handling qualities, ranging from good to unaugmented (poor) were evaluated in pitch, roll, yaw, and the combination roll and yaw axes. These handling qualities levels were successfully correlated with pipper motion, tracking error, and pilot rating and comments to the extent that acceptable handling qualities were distinguished from unacceptable handling qualities, and deficiencies were discovered and isolated. Tracking test techniques proved to be a powerful tool for optimizing the TWeaD II flight control system in an in-flight environment.

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 Aviation Safety and Pilot Control written by National Research Council and published by National Academies Press. This book was released on 1997-03-28 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adverse aircraft-pilot coupling (APC) events include a broad set of undesirable and sometimes hazardous phenomena that originate in anomalous interactions between pilots and aircraft. As civil and military aircraft technologies advance, interactions between pilots and aircraft are becoming more complex. Recent accidents and other incidents have been attributed to adverse APC in military aircraft. In addition, APC has been implicated in some civilian incidents. This book evaluates the current state of knowledge about adverse APC and processes that may be used to eliminate it from military and commercial aircraft. It was written for technical, government, and administrative decisionmakers and their technical and administrative support staffs; key technical managers in the aircraft manufacturing and operational industries; stability and control engineers; aircraft flight control system designers; research specialists in flight control, flying qualities, human factors; and technically knowledgeable lay readers.

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).

Book Synopsis Aircraft Maneuvers for the Evaluation of Flying Qualities and Agility by : David J. Wilson
Download or read book Aircraft Maneuvers for the Evaluation of Flying Qualities and Agility written by David J. Wilson and published by . This book was released on 1993 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of aircraft maneuvers has been developed to augment evaluation maneuvers used currently by the flying qualities and flight test communities. These maneuvers extend evaluation to full aircraft dynamics throughout the aircraft flight envelope. As a result, a tie has been established between operational use and design parameters without losing control of the aircraft evaluation process. Twenty maneuvers are described as an initial set to examine primarily high-angle-of attack conditions. Perhaps as important as the maneuvers themselves is the method used to select them. These maneuvers will allow direct measurement of flying qualities throughout the flight envelope instead of merely comparing parameters to specification values.
