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 Synopsis Crew Workload Assessment by : James D. Wolf

Book excerpt: The study objective was to develop a quantitative measure of workload useful in crewstation evaluation. Flight tasks of varying difficulty were simulated, and 35 pilot response variables analyzed. Selected physiological and visual response variable were applied in a stepwise regression procedure to the prediction of a composite performance/opinion measure, which reflected differing levels of task difficulty. The resulting linear equation was reformulated as a preliminary operationally-defined measure of information-processing workload. (Author).

Guidelines for the Use of Workload Assessment Techniques in Aircraft Certification written by and published by . This book was released on 1989 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Volume Two is to present specific guidelines and recommendations for evaluating workload certification plans. No attempt is being made to provide a list of simple-to-follow directions for the generation of an aircraft workload certification plan, as this is the responsibility of the manufacturer. Volume One summarizes the activities leading up to and including two user community workshops and two simulation studies conducted at the Man- Vehicle Systems Research Facility, NASA-Ames Research Center. The workload assessment techniques are discussed by domain area: Subjective, Physiological, Performance, and Analytic techniques. The distinction by domain is convenient because of the methods and equipment in common among techniques within a domain. Evaluation criteria for assessing a workload certification plan includes treatment of the validity, reliability, and applicability of candidate workload measures. For a workload measure to demonstrate validity, it must be able to discriminate among varying task demands imposed upon the flightcrew. In order for a measure to demonstrate reliability, it should provide the same results with repeated applications. Applicability is simply the ability for workload to be assessed in an aircraft flightdeck environment.
Book Synopsis Pilot Subjective Evaluation of Workload During a Flight Test Certification Programme by : Frank T. Ruggiero
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 1980 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques required to produce and validate six detailed task timeline scenarios for crew workload studies are described. Specific emphasis is given to: general aviation single pilot instrument flight rules operations in a high density traffic area; fixed path metering and spacing operations; and comparative workload operation between the forward and aft-flight decks of the NASA terminal control vehicle. The validation efforts also provide a cursory examination of the resultant demand workload based on the operating procedures depicted in the detailed task scenarios.

Book Synopsis Use of Task Timeline Analysis to Assess Crew Workload by : G. Stone
Download or read book Use of Task Timeline Analysis to Assess Crew Workload written by G. Stone and published by . This book was released on 1987 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: As systems have become more sophisticated, the role of humans in operating and maintaining them has grown more complex. There has been a steadily growing recognition that human characteristics, particularly limitations and abilities, must be considered in some depth in system design if design objectives are to met. The size and role of the crew represent critical design decisions. Mission performance has a direct relationship to the ability of the crew to carry out all of the required functions. If necessary functions overload the crew, some will be omitted and others ineffectively performed. If this is the case, automation may have to be considered. If the crew is underloaded, boredom and reduced performance may result, in addition to unnecessary costs being incurred. An additional crew member will increase weight, design costs, fuel expenditures, and training costs. It has been estimated that, for a commercial aircraft, an additional flight crew member can result in a 4 to 5 percent increase in direct operating costs. In the same manner, for a military aircraft fleet of 200 with a life-cycle of 20 years, costs can amount to several hundred million dollars for each additional crew member. Issues of crew size were so critical in preliminary design work for proposals on antisubmarine warfare (ASW) and airborne warning and control system aircraft (AWACS) that Douglas Aircraft Company conducted research on the problem.

This book was released on 1989 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of the contract was to identify assessment techniques which demonstrate evidence of validity and reliability and are suitable as measures of flightcrew workload for aircraft certification. To use a workload assessment technique with confidence for the certification of an aircraft flightdeck, the validity and reliability of the technique must be well established. Validity is the capability of the assessment technique to measure the abstract construct it is proposed to measure. Reliability is the capability of the measure to produce the same results with repeated testing. A comprehensive literature review was conducted to identify workload measures which have an empirical record of validity and reliability. All candidate workload assessment techniques had to be applicable for evaluating workload in an aircraft environment. Two workshops were conducted to bring together experts in the workload assessment field to determine candidate measures for simulation testing (aided by the literature search), and make recommendations for testing in a high fidelity simulation. Two separate simulation tests were conducted at the Man Vehicle System Research Facility at NASA-Ames Research Center using a Phase II B-727 motion-base simulator.

This book was released on 1987 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The verification of both functional effectiveness and human welfare evidently always been a major objective in flight test but a formal and rigorous investigation of the man-machine interface itself was gradually prompted by the crew complement question. In 1979, AIRBUS INDUSTRIE launched a preliminary version of the Forward Facing Crew Cockpit for installation on the A300 FF. This version incorporated all the new technology for the A310 cockpit except the Cathode Ray Tubes for flight data and system monitoring. In view of the two-man crew certification of this version we launched a major workload research programme in order to develop refined, rational and scientific methodologies for workload determination in flight test. This human factors activity was however not just started for certification purposes but also because crew workload is a fundamental design parameter influencing the cockpit design itself and the operating procedures. In this sense our work started a process which potentially could become iterative in the future so that the man-machine interface would eventually be designed, investigated and improved well before an aircraft's first flight. Also classical topics in flight test are the determination of static and dynamic stability, the former indicating the tendency of an aircraft to return to its equilibrium position, the latter indicating the way an aircraft returns to its equilibrium position.
