Improving Aircrews' Crosscheck of Flight Instruments when Using NVGs. HFM Workshop on 'What is Essential for Virtual Reality to Meet Military Performance Goals'

摘要

Current ground-based introductory night vision goggle (NVG) training consists of classroom lectures, hands-on adjustment training, terrain board demonstrations, and, for a few platforms, simulator training. The content of the lectures was developed jointly between the USAF and USN and is standardized for all platform types. NVG video sequences of actual events are integrated with the lectures to support verbal descriptions of operationally relevant concerns, such as illusion and misperceptions. Terrain boards are used to demonstrate visual phenomena specific to the NVG image resulting from the intensification process. NVG-capable simulators provide for good 'system integration' training (e.g., looking beneath the NVG at cockpit instruments, scanning the outside scene, etc. ), but due to inadequacies with the simulated imagery, there are serious limitations to 'visual' training. Consequently, terrain board demonstrations continue to be the best method of demonstrating many of the NVG image characteristics. There is currently no 'table-top' computer training available for reinforcing some of the more important NVG lessons learned from operational experience and mishaps.
