About this exam

Human Performance is one of the fourteen theoretical knowledge subjects in the EASA ATPL(A) and ATPL(H) syllabi, and it is also examined as a stand-alone subject for the ATPL. It is not a soft subject: roughly a fifth of the syllabus is physiology and another fifth is psychology, with the remainder split across human factors fundamentals, stress and fatigue, the advanced flight environment, crew coordination and operational HF. The subject exists because most accidents attributed to "pilot error" are really failures of perception, workload management, communication or decision making, and the regulator wants licence holders who can recognise those failure modes in themselves and in their crews. The examination is multiple choice with one correct answer per question, delivered by computer at an approved examination centre, using the national CAA question bank derived from the EASA central question bank. Preparation is best built in layers: learn the physiology properly first (hypoxia, hyperventilation, decompression, spatial disorientation and the eye are heavily examined and easy to confuse), then the psychology models, then the operational material. Work through the learning objectives line by line, answer questions only after each topic is understood, and log every wrong answer with the reason it was wrong. Your national CAA publishes the current question count, time allowed, pass mark and fees, and these change, so check its website rather than relying on second-hand figures.

Common questions

About ATPL 040 Human Performance preparation

How is the exam delivered and what does a question look like?

It is a computer-based multiple-choice examination at an approved examination centre, with one correct answer per question and no partial credit. Questions are short, factual and often numerical or comparative: which symptom appears first at a given altitude, which illusion follows a particular acceleration, which memory system is in use. Read every option before answering, because distractors are usually true statements applied to the wrong situation.

How many questions are there, how long do I get, and what is the pass mark?

These are set by the examining authority and are revised from time to time, so no figure given here would be reliable. Your national CAA publishes the current question count, time allowed, pass mark and sitting fee on its website and in its examination guidance for candidates. Check that guidance before you book, and check it again if you are sitting some months after you first looked.

How difficult is Human Performance compared with the other ATPL subjects?

The content is not mathematically hard, but the volume of terminology is large and many topics are easy to half-learn. Hypoxia versus hyperventilation, the various barotraumas, and the different spatial disorientation illusions are classic sources of lost marks because they feel familiar but differ in detail. Candidates who memorise without understanding tend to plateau in the mid-range and struggle to push higher.

What is the best study order within the subject?

Start with basic concepts and the SHELL model so the vocabulary is in place, then do physiology in full, including the ear, eye and spatial orientation, because these underpin the advanced physiology later. Move to psychology and information processing, then stress, fatigue and circadian rhythms, then advanced physiology, then crew coordination and operational HF. Finish with mixed question practice across all domains.

Where do candidates most often lose marks?

Confusing hypoxia with hyperventilation, forgetting that symptoms worsen with altitude and that time of useful consciousness falls sharply above about 35,000 feet, muddling the somatogravic and somatogyral illusions, and misreading questions about the semicircular canals. In psychology, candidates mix up short-term and long-term memory limits and the stages of the decision-making models. In operational questions, they choose the answer that sounds safest rather than the one the procedure specifies.

Can I retake the examination if I fail, and how soon?

Retake rules, waiting periods and any limit on the number of attempts are set by the examining authority and by the Part-FCL requirements in force, so confirm them with your national CAA and your flight training organisation. In practice, book the retake only after you have identified why you failed: a weak domain, misreading of questions, or running out of time. A retake without that diagnosis usually reproduces the same result.

How should I use question banks without relying on them?

Use them as a diagnostic, not as the syllabus. Answer a block of questions, then for every wrong answer write one line on why the correct option is correct and why yours was not. Revisit the underlying learning objective rather than memorising the question. If you can explain a topic to another candidate without notes, you are ready for it; if you can only recognise the answer, you are not.

Does Human Performance content overlap with other ATPL subjects?

Yes, and deliberately. Principles of flight overlaps with spatial disorientation and the vestibular system, flight planning and performance with hypoxia and decompression, communications with crew coordination, and air law with just culture and safety reporting. Studying these overlaps once, properly, saves time across several examinations and makes the operational questions in Human Performance much easier to reason through.

Is this page affiliated with EASA or my national CAA?

No. This is independent study material written for candidates preparing for the ATPL Human Performance examination. It is not produced, endorsed or approved by EASA, any national civil aviation authority, or any examination centre. Always treat the current official syllabus, the current Part-FCL requirements and your national CAA's examination guidance as authoritative over anything you read here.
