Assessment of Crew Workload Measurement Methods, Techniques and Procedures. Volume 2. Guidelines for the Use of Workload Assessment Techniques in Aircraft Certification
Abstract
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.
