NASA’s Use of Human Performance Models for NextGen Concept Development and Evaluations

Integrated Human Performance Model (HPM) validity is a paramount concern when HPM predictions are used for next-generation aviation system development. HPM validity is a challenge because of the integrated nature of the HPM and because many of the embedded behaviors may not be readily observed. A rigorous validation process is required to arrive at valid integrated HPMs and improve the credibility of the models being developed. This credibility impacts the subsequent use of the model to explore concepts being proposed for future systems. The current paper will highlight a recent methodical validation approach that was developed and applied to a Federal Aviation Administration (FAA)-National Aeronautics and Space Administration (NASA) HPM of a candidate NextGen concept of operations using the Man-machine Integration Design and Analysis System (MIDAS v5). The HPM that was developed was deemed valid from multiple levels using multiple input and output parameters.
