AVIATION HUMAN
FACTORS PRACTICE TEST
COMPLETE 60 QUESTIONS
Question 1: Which statement best describes the purpose of human factors in
aviation?
Choices:
1) To eliminate the need for procedures 2) To optimize the �t between people and the systems in which they work 3) To replace human operators with automation 4) To measure only physical �tness of �ight crews Correct Answer: To optimize the �t between people and the systems in which they work Explanation: Human factors applies knowledge of human capabilities and limitations to the design and operation of aviation systems so that people, equipment, procedures, and environments work together more safely and e�ectively.Page 1
Question 2: In the SHELL model, what does the central Liveware element represent?
Choices:
1) The individual human operator 2) The aircraft hardware only 3) The regulatory environment 4) Written procedures and manuals
Correct Answer: The individual human operator
Explanation: The central Liveware element represents the human at the center of the work system. The surrounding Software, Hardware, Environment, and other Liveware elements interact with that person.Question 3: A poorly shaped cockpit control causes frequent selection errors even though pilots are well trained. Which SHELL interface is most directly involved?
Choices:
1) Liveware-Environment 2) Liveware-Liveware 3) Liveware-Hardware 4) Liveware-Software
Correct Answer: Liveware-Hardware
Explanation: Control shape and placement are physical equipment characteristics, so the mismatch is primarily at the Liveware-Hardware interface.Page 2
Question 4: A checklist uses ambiguous wording that di�erent crews interpret di�erently. Which SHELL interface is most directly a�ected?
Choices:
1) Liveware-Software 2) Liveware-Hardware 3) Hardware-Environment 4) Liveware-Liveware
Correct Answer: Liveware-Software
Explanation: Procedures, manuals, checklists, and other nonphysical rules are Software in the SHELL model. Ambiguous checklist wording therefore creates a Liveware-Software mismatch.
Question 5: Why is a systems approach preferred when investigating human error?
Choices:
1) It assumes every error is caused by inadequate training 2) It focuses only on the person who made the �nal mistake 3) It considers how organizational, task, environmental, and human factors interacted 4) It avoids examining equipment design Correct Answer: It considers how organizational, task, environmental, and human factors interacted Explanation: A systems approach examines the broader conditions that shaped performance instead of treating the �nal operator action as the only cause.Page 3
