  1. Virtual Reality for Training Hazardous Helicopter Tasks Lochlan Magee & Franklin Lue DRDC Toronto Canada Defence Research and Development Canada Recherche et développement pour la défense Canada

  2. Deck Landing

  3. Objectives • Find an effective, affordable solution for training helicopter deck-landing skills • Establish simulations and technologies applicable to other helicopters and demanding flight tasks • Transition technology to CF & Canadian Industry

  4. Exploratory Developments Two models • State-of-the-art components • Commercial-off-the-shelf (COTS) components

  5. State-of-the-art approach Developed for DRDC Toronto by the University of Toronto Institute for Aerospace Studies (UTIAS)

  6. Component technologies • High resolution, stereo FOHMD • MaxView IG • Hydrostatic, 6 dof motion base • McFadden control loaders

  7. Video Presentation

  8. Reverse transfer of training • Methods • 24 CF helicopter pilots (12 Sea King) • 50 deck landings each • Ship-helicopter operational limits • No quiescent period • No aids, no instruction • Limited feedback

  9. Predictions • On first exposure, Sea King pilots should land the helicopter in the trap more frequently than non-Sea King pilots • Non-Sea King pilots should improve with practice while Sea King pilots do not

  10. Results • Both groups performed poorly at first, but • Sea King pilots rapidly adapted to the simulator and showed no improvement with practice • non-Sea King pilots steadily improved with practice

  11. COTS approach Developed at DRDC Toronto

  12. Component technologies • Low cost HMD • General purpose image generator • Electric, 6 dof motion base • Seat vibrators • Springs for control loading

  13. Video Presentation

  14. Inter-simulator transfer of training • Methods • 12 CF helicopter pilots (not Sea King) • 40 deck landings at DRDC Toronto • 40 deck landings at UTIAS • all other experimental conditions identical

  15. Predictions • the pilots should steadily improve with practice • they should do better than the prior group of non-Sea King pilots when they first fly the SOA simulator

  16. Results • the pilots steadily improved with practice using the COTS simulator • their learning curve was unbroken when they transferred to the SOA simulator • they performed better than both prior groups (Sea King and non-Sea King) on their first encounter with the SOA simulator

  17. Findings of laboratory-based testing • The SOA simulator allowed Sea King pilots to demonstrate skills they had acquired at sea • Both simulators provided opportunity for inexperienced pilots to learn • The COTS approach affords a viable alternative for providing the sensory cues needed to perform the task

  18. Helicopter Deck Landing Simulator (HDLS) • Advanced development model • Instructional features • Full control of the scenario • Day & night • Free-deck & haul-down landings • Networked simulation

  19. LSO Simulator

  20. Technology Transfer • CFB Shearwater • Atlantis Systems • International HVT • Jet Ranger

  21. Jet Ranger Simulator • Testing • Multi-use • Two seat operation • Generality of results • Auto-rotations

  22. Video Presentation
