ExploreAbout this exam
The CPL Human Factors examination is the human factors component of the Commercial Pilot Licence theory pathway. It is aimed at student pilots working toward a commercial licence, and at licence holders or overseas applicants who need to satisfy the human factors knowledge requirement. The subject area covers the human operator as part of the aviation system: perception and information processing, attention and workload, decision making and judgement, error and threat management, situational awareness, communication and crew coordination, personality and attitudes, stress, fatigue and sleep, fitness and health, vision and hearing, spatial disorientation and illusions, and the effects of drugs, alcohol and medication on performance. It also addresses how organisational and operational factors, including automation and human-machine interface design, contribute to accidents and incidents.
Preparation should combine structured study with active recall. Work through a current syllabus or training provider's course outline, read a recognised human factors text, and then test yourself with practice questions that require applied reasoning rather than memorised definitions. Because human factors questions are usually scenario based, practise identifying the underlying concept in a short narrative and choosing the most safety-conservative response. Keep a log of errors, revisit weak topics such as fatigue and decision making, and confirm examination logistics with the regulator or your flying school, since published details can change.

What you'll study
About CPL Human Factors preparation
Who needs to sit the CPL Human Factors exam?
It is intended for candidates completing the human factors knowledge requirement for a Commercial Pilot Licence, typically student pilots in a integrated or non-integrated course. If you already hold a licence or a foreign qualification, check with the regulator or your flying school whether your existing human factors study is recognised before enrolling.
How long is the exam and how many questions are there?
We cannot state this reliably. The official page we attempted to reference returned a 404 error, so no current question count or time limit is confirmed here. Confirm the current paper structure, time allowed and any permitted reference materials directly with the regulator or your approved training provider before your sitting.
What pass mark applies?
The pass mark is not confirmed by our source, so we do not publish a figure. Pass standards can differ between the regulator's examinations and a training provider's internal progress tests. Ask your school for the standard applied to your assessment and aim comfortably above the minimum rather than targeting the threshold.
How should I order my study?
Start with basic human performance: sensation, perception, attention and memory. Then move to applied topics such as workload, decision making, situational awareness, error management, fatigue and stress. Finish with integration topics, including crew communication and automation. Test each block with applied scenario questions before moving on, and revisit earlier material in the final two weeks.
Is Human Factors harder than the technical subjects?
Many candidates find it easier to read but harder to answer well. Technical subjects reward recall of defined values; human factors questions often describe a scenario and ask for the most appropriate action or the underlying concept. Candidates who memorise lists without practising interpretation tend to lose marks on these applied items.
What are the most common failure modes?
Three recur: treating fatigue, stress and alcohol as separate trivia lists rather than linked performance limiters; choosing the action that solves the immediate problem instead of the most safety-conservative option; and misreading a scenario by skim-reading. Slow down, identify what the question is really testing, and eliminate options that rely on willpower or memory to fix a systemic problem.
Can I retake the exam if I fail?
Retake rules, waiting periods and any fees are not confirmed by our source, so we cannot state them. Policies are set by the examining body and can change. Check the regulator's current candidate information or ask your flying school about the process, associated costs and whether additional training must be completed before a further attempt.
How much study time should I allow?
There is no official figure we can quote. As a practical guide, allow several weeks of part-time study alongside flight training, with at least one full revision pass and repeated practice on applied questions. If you are weak on fatigue, decision making or spatial disorientation, budget extra sessions for those topics rather than spreading time evenly.
Are practice questions enough on their own?
No. Practice questions are most useful after you have built a framework from a proper text or course. Use them to diagnose weak areas, then return to the underlying material. Relying on question drills alone leaves you unable to handle unfamiliar scenarios, which is where applied human factors papers typically separate candidates.
