The U.S. Army Airborne Command and Control System A2C2S is a command and control C2 system consisting of an A-kit and a B-kit and will be hosted by the utility helicopter UH-60L and newer Blackhawk. The A2C2S Product Manager PM requested the U.S. Army Research Laboratorys ARLs Human Research and Engineering Directorate to perform an evaluation of the emergency egress characteristics of the A2C2S to help support the low rate initial production LRIP milestone decision. ARL and the PM developed a plan to evaluate the emergency egress characteristics of the A2C2S using a combination of human figure modeling and egress testing. The evaluation plan used human figure modeling to perform a detailed analysis of all egress routes to identify whether the larger end of the male Soldier population, with equipment, could fit through the egress routes and to identify design characteristics of the A2C2S that enhance or degrade the Soldiers ability to egress the aircraft. The emergency egress test was used to validate the results of the model, verify that the egress could meet the time requirements, and identify additional safety concerns that may be encountered during actual egress trials. The results of the egress modeling identified some shortcomings with the egress characteristics of the A2C2S however, the results were favorable. The results of the egress testing validated the modeling that was performed. In addition, all egress trials successfully met or exceeded the 30-second time standard for emergency egress. The results and recommendations from the modeling and testing were provided to the PM to help drive design modifications that, if implemented, could enhance the emergency egress characteristics of the A2C2S.
