Abstract : The objective of the study is to develop methods and techniques for evaluating human operator performance during field testing of Navy systems. The procedure adopted has been to develop and test the evaluation techniques using a particular Navy system. After examination of various systems the pilot station of the P-3C Anti-Submarine Warfare (ASW) aircraft system was selected for use in development and trial. A detailed description of the information flow through the operator is basic to the development of human factors evaluation measures. The field evaluator must have such a descriptive technique in his repertoire to update prior descriptions or generate his own. The Mission Time Line Analysis (MTLA) has been used and evaluated in this study with a bar chart time related format. From the MTLA evaluative judgements regarding workload per block of mission time, task concurrency and delayed or indeterminate feedback can be made. The MTLA also provides the basis for measurements of errors in carrying out task sequences and procedures. An important use of the MTLA is in identification of measurement points within the system at which human operator performance may be realiably and practically assessed. (Author)
