Responsibility for Aviation Risk Management
Aviation risk management is the backbone and general goal of modern aviation safety management systems (SMS).
Developing the maturity of an aviation SMS program is tantamount to cultivating more sophisticated, accurate, and proactive risk management strategies.
Responsibility in aviation risk management is kind of a messy word. Historically and structurally, aviation SMS programs are depicted as being top-down.
The clean answer as far as "who has responsibility for risk management" is that management does.
