Helicopter Flight in Degraded Visual Conditions

Final summary report on research conducted for the CAA by QinetiQ on helicopter flight in degraded visual conditions. The work comprised a review of accident data for the period 1975 to 2004, simulator trials using two test pilots and six representative accident scenarios, analysis of the simulator trials results including linking quantitative measures of visual scene content with pilot workload ratings, and a review of relevant civil regulations. The report also contains the final report on earlier work on helicopter pilot view, previously published in CAA Paper 95014.
