The goal of the ISS study was to assess how effective software tools and associated interfaces developed by the AMO project in the ground-based study are at supporting a more autonomous (crew-centered) concept of operations for the SSC’s and TOCA on the ISS. This study assessed if the information provided onboard by the AMO software tools and accessed through AMO interfaces enhances crew situational awareness sufficiently that the crew is able to make accurate operational decisions and operational recommendations to the ground, rather than the other way around.
After ground-based testing, the experiment moved to the International Space Station (ISS). It integrated the technologies and operational concepts into a functional operations environment. Specifically, a subset of the technologies employed in the DSH were matured for use onboard the ISS in order to help the crew autonomously operate systems like those they will operate during future missions without assistance from the flight control team (FCT).
Findings from the ground-based study indicate: 1) Workload of both crewmembers and FCT members generally increased along with increasing time delay; 2) Advanced procedure execution viewers, caution and warning tools, and communications protocols such as text messaging decreased the workload of both flight controllers and crew, and decreased the difficulty of coordinating activities; and 3) Whereas crew workload ratings increased between 50 seconds and 300 seconds of time delay in the baseline configuration, workload ratings decreased in the mitigation configuration.
Results from the ISS portion of this study aren’t available.
