Available in PDF, EPUB and Kindle. Book excerpt: At present the most used and probably the most reliable methods for assessing pilot workload in flight are based on some form of subjective reporting by experienced test pilots. Unfortunately, subjective opinions are susceptible to bias and preconceived ideas and so many occasionally result in false estimates of workload. For more than fifteen years subjective reporting by pilots at RAE Bedford has been augmented by recording their heart rates. At first pilots described workload in a relatively unstructured manner but the need for some form of rating scale was soon apparent. After much trial and error and with the valuable assistance of practising test pilots a ten-point rating scale using the concept of spare capacity was developed (fig 1). The overall design is based on the Handling Qualities Rating Scale of Cooper and Harper already familiar to Bedford test pilots and sometimes used previously, though mistakenly, to rate workload. During the last eight years a number of flight trials at Bedford, including the Harrier 'ski-jump' take-off trial and the Economical Category 3 landing trials, have used pilot ratings and heart rate responses to assess workload. The rationale for using heart rate in assessing pilot workload is based on the concept of neurological arousal. Flying an aeroplane, especially during the more difficult manoeuvres, requires the pilot's brain to collect, filter and process information quickly, to exercise judgement and make decisions, and to initiate rapid and appropriate actions.

Book excerpt: Currently, the most used and probably most reliable methods of estimating levels of pilot workload in flight are those based on some form of subjective reporting by experienced test pilots. But subjective opinions are susceptible to bias and to pre-conceived ideas and so the use of a second and more objective measure to augment these opinions would seem to offer distinct advantages. This paper describes the way in which a pilot's heart rate can be recorded to support, or occasionally question, his subjective rating of workload. A small number of examples from RAE Bedford trials are presented to illustrate the technique, and a short description is given of the BAe 146 Crew Complement Certification exercise. Finally, a current flight experiment to compare heart rate levels and workload ratings in a more scientific manner is described.

Book excerpt: The assessment of levels of pilot workload associated with the various phases and sub-phases of flight is important in the design, development, and evaluation of aircraft handling qualities and of display and guidance systems. This AGARDograph, written primarily for flight test engineers and pilots, is intended as a guide to the different methods available for estimating workload and in particular to those techniques suitable for use in aircraft. An introductory chapter briefly reviews the various concepts and classifications of workload; the former tend to fall into two main areas, those related to workload as task-demands and those to workload as pilot-effort. In Chapter 2, subjective assessment, at present the most used method, is discussed from the viewpoint of the test pilot. Physiological methods in general are reviewed in Chapter 3 with those techniques available for use in flight being discussed in more detail. Chapter 4 describes various objective methods and presents examples of their practical application. Whereas the methods in Chapter 2 and 3 are appropriate only to workload as effort, objective methods contain techniques appropriate to workload as task-demands as well as to effort. The former techniques are particularly valuable for providing data which can be used to construct models and to predict levels of workload. Different modelling techniques will be discussed in a proposed supplement entitled Engineering Methods.

Download or read book Pilot Subjective Evaluation of Workload During a Flight Test Certification Programme written by Frank T. Ruggiero and published by . This book was released on 1987 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: To date there is no agreed upon definition of mental workload and therefore there is no agreement on how it should be measured. Current workload researchers do seem to agree on at least three aspects of mental workload: it is multidimensional construct, a clear distinction must be maintained between imposed mental load (task load) and the mental load as experienced (subjective load), and the use of subjective ratings should be central to any investigation of workload. On this last point, The President's Task Force on Aircraft Crew Complement made the following recommendations: This technique (task/timeline analysis based on comparison with previous aircraft designs), supplemented by improved subjective evaluation methods applied by qualified pilots, will offer the best means for demonstrating compliance with faa crew complement criteria. We recommend that FAA incorporate such methods in the tests to be employed for the certification of the B-757 and B-767 aircraft. The paper outlines the Pilot Subjective Evaluation (PSE) process developed by Boeing, in conjunction with the FAA, to supplement the analytical, simulator, and flight test crew workload evaluation techniques used to demonstrate compliance with the minimum crew size requirements of FAR 25.1523 and Appendix D(4).

This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work performed in the first year of a continuing research project aimed at developing useful methods for measuring the workload of pilots operating aircraft in the ATC system. Good methods of measuring mental workload of human operators are needed to evaluate the introduction of new technology and new procedures in the man-machine environment. The present research is concentrating on developing subjective assessment methods for any phase of an IFR (Instrument Flight Rules) flight and any crew station on the flight deck. One of the results achieved in the first year is an expanded conceptual structure which allows a more precise definition of terms and assumptions in defining pilot mental workload in a multi-task environment. A second area of research has concentrated on reviewing the alternative approaches to developing a measurement scheme for workload, with some emphasis on the subjective assessment approach. A tentative result in this area is the generation of a prototype subjective rating method for IFR pilot workload modeled closely on the Cooper-Harper rating developed in 1969 to evaluate aircraft handling qualities. This scheme and others will be tested in a transport aircraft simulation during the coming year. If successful, it will be used in a variety of cockpit simulators at NASA research centers (Ames and Langley) and FAA NAFEC as part of a joint research program to evaluate cockpit display of traffic information.

This book was released on 2010-04-29 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: To design and develop capable, dependable, and affordable intelligent systems, their performance must be measurable. Scienti?c methodologies for standardization and benchmarking are crucial for quantitatively evaluating the performance of eme- ing robotic and intelligent systems’ technologies. There is currently no accepted standard for quantitatively measuring the performance of these systems against user-de?ned requirements; and furthermore, there is no consensus on what obj- tive evaluation procedures need to be followed to understand the performance of these systems. The lack of reproducible and repeatable test methods has precluded researchers working towards a common goal from exchanging and communic- ing results, inter-comparing system performance, and leveraging previous work that could otherwise avoid duplication and expedite technology transfer. Currently, this lack of cohesion in the community hinders progress in many domains, such as m- ufacturing, service, healthcare, and security. By providing the research community with access to standardized tools, reference data sets, and open source libraries of solutions, researchers and consumers will be able to evaluate the cost and be- ?ts associated with intelligent systems and associated technologies. In this vein, the edited book volume addresses performance evaluation and metrics for intel- gent systems, in general, while emphasizing the need and solutions for standardized methods. To the knowledge of the editors, there is not a single book on the market that is solely dedicated to the subject of performance evaluation and benchmarking of intelligent systems.
Download or read book Pilot Workload written by Anthony D. Andre and published by Psychology Press. This book was released on 1995-05-01 with total page 136 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Evaluation of a Pilot Workload Assessment Device to Test Alternate Display Formats and Control Handling Qualities written by Samuel G. Schiflett and published by . This book was released on 1982 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This in-flight research project evaluated the utility of a Workload Assessment Device (WAD) to measure pilot workload for approach and landing tasks under simulated instrument meteorological conditions, alternate HUD formats and control stability variations. The hardware software, and test procedures associated with the WAD functioned efficiently with only minor discrepancies and minimum pilot distraction. The project established the feasibility of using an item-recognition task as a measure of sensory-response loading and reserve information processing capacity while flying precision approaches. In a descriptive statistical treatment of the data, the results indicate an appreciable increase in reaction time and errors with degraded handling qualities as compared to ground baseline measures and good handling qualities. The preliminary findings also reveal consistent trends toward the availability of more mental reserve capacity when flying predominantly pictorial/symbolic HUD configurations as compared to conventional HUD formats with scales and alphanumerics.
Download or read book USAF Pilot Perceptions of Workload Assessment in a Combat Or High Threat Environment written by Kadircan Kottas and published by . This book was released on 1997-12-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study analyzed the self reported survey responses of 219 Air Force Pilots concerning their perceptions of workload assessment in a combat or a high threat environment. The first objective of this study was to determine and compare the combat workload factors of varying importance in combat workload assessment by aircraft and mission type flown. The second objective was to examine the pilots' perception of combat mission inflight workload. A stepwise regression model to predict the pilots' perceptions of inflight workload using pilots' characteristics data was explored. Research conclusion varied among aircraft types. Combat workload items indicated as distractingly important were similar for all aircraft types, while items in lower level of importance were impacted by aircraft type. Mean Combat Workload (CWL) scores of pilots from each aircraft type were not significantly different. Overall, it was concluded that surveying pilots who had flown in combat or high threat environments provided useful responses to assess pilot workload; however, findings based on subjective assessments, provide tentative grounds for further research.

Book excerpt: This current experiment was an attempt to measure workload during flight simulation, using two primary variables: the pilots' own evaluation sampled once per minute with a computer and the latency or delay of that response. This was supplemented by a post-flight questionnaire. Three levels of flight difficulty were established by subject matter experts. These were varied by controlling (1) initial clearance complexity, (2) level of air traffic control, (3) turbulence, and (4) inflight emergency. Flights were conducted in a General Aviation Instrument trainer and 12 pilots participated. Results demonstrated that pilots were willing and able to make inflight workload evaluations which corresponded directly with the induced difficulty level. Response latencies increased in relationship to difficulty, but the intermediate and most difficult flights were not significantly different. Factor analyses of all measures produced two clusters for the easiest and intermediate flights (inflight and postflight) and four for the most difficult flights. In the latter case, inflight and postflight measures separated into two factors and the questionnaire split also into two segments. These separations indicated that within the current state of the art, both types of measures should continue to be collected. Plans call for follow-on research in General Aviation Workload.
