What trend replaced the 'machine error' focus in aviation safety?

• A. A shift toward understanding and managing human error
• B. Increased focus on engine reliability
• C. Greater emphasis on weather prediction
• D. More attention to baggage handling

Answer: (A)

The shift from blaming machines to understanding human performance within a larger system is what this question is getting at. In aviation safety, researchers and practitioners moved away from saying a crash happened because the aircraft or engine failed, and toward examining how people interact with the aircraft, procedures, and organizational factors. This means studying why pilots or controllers might misread a situation, how workload and fatigue affect decisions, and how training, communication, and cockpit design can reduce the likelihood of error. Concepts like crew resource management, standardized checklists, fatigue management, and error-tolerant procedures embody this approach, aiming to structure the system so that human error does not lead to catastrophe. Other areas—focusing primarily on engine reliability, weather prediction, or baggage handling—are important, but they don’t capture the overarching shift in safety thinking. They either emphasize specific technical components or separate hazard domains rather than the integrated, people-and-process–centered view that reduces risk across the entire aviation system.
