In this paper, we describe an ongoing effort to envision and articulate requirements for the United States Army’s Future Vertical Lift (FVL) program, specifically related to crewing. The goal of FVL is to develop a new family of rotorcraft that will incorporate advanced technologies to support new capabilities. We will discuss the challenges associated with envisioning a future system, along with approaches to design for the envisioned world with examples. We emphasize the importance of focusing on the envisioned work domain, rather than advances in new technologies. We recommend that by articulating the future work domain, requirements for new technologies that will support human crew members can be more easily articulated. When designing for an envisioned world, it is important to incorporate relevant perspectives early and often throughout the process.
