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.

Book excerpt: Pilot workload may be defined as the cost incurred by the human operators of complex airborne systems in accomplishing the operational requirements imposed on them. If all pilots could perform all flight-related activities on time without error, and if they could do so using available hardware, software, and human resources, the concept of workload would have little practical significance. However, they often cannot. Automation has been offered as a solution to an increasing number of workload-related problems in existing systems or predicted for those under development. In addition, there has been an ever-increasing tendency to reduce the number of crewmembers in aircraft cockpits. Again, automatic subsystems are provided to moderate the demands thus placed on the remaining crewmembers. Attempts to completely replace humans by automatic systems have failed, however, because human capabilities, adaptability, and flexibility continue to surpass those of the most advanced and sophisticated systems. To achieve the desired levels of overall system effectiveness, aircraft must be designed that take advantage of the capabilities of the remaining crewmembers and impose acceptable levels of workload. Thus, the concept of workload has received an increasing amount of theoretical attention during the past decade and it has become an important consideration in system design.

Book excerpt: This project evaluated several methods for measuring pilot performance in a general aviation simulator and examined the relationship between performance and workload. An Automated Performance Measurement (APM) system was designed for use in a flight simulator which was instrumented for digital data collection. Performance rating was accomplished by three independent observers. Workload was assessed using a real-time subjective input system with which pilots provided workload estimates every minute. Two groups of pilots participated in the experiment: ten professional high-time pilots and ten recently qualified instrument pilots. Both the APM and the observer ratings showed significant performance differences between the two pilot groups. The automated technique showed more of a spread, however, among individuals in the professional (masters) group. The newly qualified pilots (journeymen) reported significantly higher workload than their masters counterparts and their performance was significantly worse.
Download or read book Toward the Definition and Measurement of the Mental Workload of Transport Pilots written by Thomas B. Sheridan and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the various types of objective methodologies that either have been or have the potential of being applied to the general problem of the measurement of pilot workload as it occurs on relatively short missions or mission phases. Selected studies that have dealt with the workload measurement problem or some similar problem are reviewed in relation to their applicability to securing answers to operational questions. The types of methods are classified as: laboratory, analytic and synthetic, simulator, and in-flight. The paper concludes with a general discussion of the relative merits and some of the cautions to be observed in attempting to apply these methods and in trying to interpret the results with a view toward generalizing to operational situations.

Available in PDF, EPUB and Kindle. Book excerpt: The operating environment of an air transport crew is characterized by multiple interrupting tasks, these tasks being composed of a mixture of purely physical control and purely mental planning processes. Measurement of crew workload is thus d difficult undertaking due to the necessity to resolve workload contributions imposed by several sources. These sources include physical efforts, mental efforts, random task interruptions, and emotional disturbances. A multiattribute, subjective opinion rating scale is presented for usa as an effective measure for this air transport cockpit environment. An analysis is performed which indicates that a major component of workload is induced by the federal air traffic control system. Mechanizations of this loading inClude speed and altitude restrictions imposed by regulation, confinement and restraint imposed by the structure of the National Airspace System, and loads induced by a stochastic interruption process associated with ATC voice communications, In fact, the analysis of a routine transport arrival into Boston's Logan airport indicates that the (primarily system induced) workload levels in the terminal area, may be higher than the (primarily aircraft induced) workload levels on final approach. A fixed base, Boeing 707 simulator was employed to investigate the consistency, sensitivity, and acceptability- of the 31, subjective rating scale. Four airline pilots and four general aviation, IFH pilots flew a series of routine, MI2 arrivals from high altitude cruise into Boston's Logan airport, each arrival terminating with a standard instrument approach. Consistent ratings were achieved across the airline subjects for all segments of the arrivals. In general, all subjects seemed receptive to the subjective assessment methodology.
