SESMA
British Airways developed the Special Event Search and Master Analysis (SESMA) in the 1970s. Safety Services uses SESMA to publicize data (which BALPA deidentifies) to recognize safety trends and to foster improvements. BASIS and SESMA are complementary, but distinctly different, safety programs.
Safety Services compiles this information into meaningful and valuable data and analysis and publishes a monthly report in a pamphlet called Flywise. Thus, both management and flight crews are informed about the latest perils in the system and are motivated to keep up the good work and avoid what has happened to others. When watching for trends and ways to improve safety, British Airways has solid data with more than 800 Air Safety reports (ASRs) and SESMA inputs a month to draw from.
