Abstract
Recently, small unmanned aircraft systems have become ubiquitous in military battlefield operations due to their intelligence collection capabilities. However, the operator's interaction with the system and the system's environment reduces potential surveillance time, thus encouraging further research into human system integration (HSI). Single operator-focused discrete event simulation serves to evaluate Human Computer Interaction (HCI) for multi-vehicle employment. The model incorporates statistical time measurement for operational tasks, as well as empirical models of HCI performance. Paired t-tests show statistical benefit in surveillance time of employing autonomous relay navigation and managing multiple pairs of small unmanned aerial systems for beyond line-of-sight missions.
