Abstract : 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).
