Beyond Full Flight Simulators: Investigating Mini Motion Platforms in Helicopter VR Simulation

Abstract: Virtual Reality (VR) is increasingly being explored as a cost-effective and flexible alternative to traditional full flight simulators for flight crew training. In addition to reducing costs, VR-based simulators offer greater versatility by integrating a range of Commercial Off-The-Shelf (COTS) components. One such component is the mini motion platform—compact motion devices that are significantly smaller and less complex than the full-scale hexapod platforms typically used in full flight simulators. However, their limited motion range raises questions about the extent to which they can meaningfully contribute to the realism and effectiveness of flight training.This study investigates the integration of a mini motion platform, paired with a classical washout algorithm, in a VR-based helicopter flight simulation environment. Using a setup that includes COTS helicopter controls, a mini motion platform, and a Varjo XR-3 headset, participants performed a series of helicopter flight tasks. Data was collected across scenarios with and without motion support, focusing on metrics such as user comfort, pilot performance, and subjective user experience.The results shed light on both the opportunities and limitations of using mini motion platforms in this context. In particular, they underscore challenges in cueing highly dynamic helicopter maneuvers, while also identifying specific areas where such platforms can enhance training outcomes. The insights from this research contribute practical recommendations for leveraging mini motion platforms to support effective and immersive VR helicopter flight training.
