The EHEST Study on the Potential of Technologies to Mitigate Helicopter Accident Factors was published on 7 October 2014. Click here for information.
The EHSIT Technology team was created to assess the potential of technologies to mitigate safety issues. Technology is not high on the list of highest ranking SPS’s. Technology provides a variety of solutions that can (directly or indirectly) address the safety issues identified in the EHSAT analysis and that can contribute to prevent different types of accidents or to increase survivability.
The ST Technology consists of a range of stakeholders, with various expertise and backgrounds. The main goal of the team is to list technologies and link them with accident causes and contributing factors as identified in the EHSAT analyses. The team developed a tool that links the results of the EHSAT analysis (incident / accident causes and their contributing factors) to R&D and technological developments. The tool contains a list of technologies (technology database) and a technology – safety matrix providing rows with technologies and columns with Standard Problem Statements (SPS’s). As the total number of SPS items is rather large, the matrix only includes the top 20 (level 2) SPS items as revealed by the EHSAT analysis of more than 300 accidents.
The process consists of two steps:
- The technology database is filled with relevant technologies for the period 2006 till present; the basic selection criteria for the technologies are: new (emerging) technologies, existing technologies not yet used on helicopters, and existing technologies used on large helicopters but not yet on small helicopters;
- The listed technologies are scored against each of the SPS items; this process involves two rating elements, the results of which are automatically summed: Impact (how well can the technology mitigate the specific SPS) and Usability (can the technology be utilised for a specific SPS and against what relative cost), each on a scale from 0 to 5; colours will automatically appear once the score is available.
