A SCORE SYSTEM TO PRIORITIZE DESIGN SAFETY FEATURES

摘要

Safety features introduced in recent rotorcraft designs have not made their way into the bulk of the rotorcraft flying fleets around the world in spite many of them have been firstly introduced many years ago in newly certified platforms. The longevity of the current rotorcraft population has proved to be exceeding all the expectations and forecast that were made when these features were introduced. However the flat trend in accident rates and fatalities verified in these years especially in some sectors is urging the regulators and many other stakeholders to take action. Hence the need to define a method able to establish rational priorities to push the new safety features into the market, by using quantitative and qualitative criteria.
