NAS Infrastructure Management System Build 1.5 Computer-Human Interface

摘要

Human factors engineers from the National Airspace System (NAS) Human Factors Branch (ACT-530) of the Federal Aviation Administration William J. Hughes Technical Center conducted an evaluation of the NAS Infrastructure Management System (NIMS) Build 1.5 computer-human interface (CHI) software. They conducted the evaluation at the NIMS Premier Facility (NPF) during November 1998. Five Airway Facilities Specialists serving as representative users employed scripts exercising the three applications that comprise NIMS Build 1.5. This software represented an interim build, and the NPF server did not represent the anticipated final configuration. This placed limits on the scope and content of the evaluation. The results of the evaluation indicated that system functionality could be improved by addressing several CHI areas. The human factors engineers determined that NIMS Build 1.5 has the potential to support an Operations Control Center Specialist in a centralized monitoring and control facility. However, at its tested maturity level, it was not capable of providing this support in an operational environment. They concluded that the majority of issues identified could be mitigated through the application of human engineering principles.
