Human factors topics in exams
Human factors cover: fatigue, stress, decision-making, communication and situational awareness. These topics appear in both A2 and STS-01/02 examinations.
The exam tests the ability to recognise dangerous human factors: fatigue after a long work day, hasty decision-making under time pressure, and stressors that degrade pilot decision quality.
Exam tip
Common mistakes in human factors
Candidates incorrectly answer questions on fatigue triggers (e.g. believing caffeine fully neutralises fatigue — it does not) and the consequences of communication failures.
Another nuance: stress can temporarily sharpen attention, but chronic stress is dangerous. The exam tests whether candidates understand this distinction.
Human factors in the STS exam
STS examinations are more detailed on human factors: teamwork, Crew Resource Management (CRM) principles and error-chain recognition.
STS-01/02 pilots often work in teams or coordinate with third parties — so communication and responsibility-sharing questions are particularly significant.
Practical study recommendations
Study human factors through the lens of real incidents — why did violations occur and what human error chain led to the outcome? A2STS presents scenario-based questions, not just abstract facts.
Recommended source: EASA's 'Study on Drone Incidents and Accidents' — this document illustrates how human factors contribute to real-world incidents.
Frequently asked questions
- How many human factors questions appear in the A2 exam?
- Typically 2–4 questions out of 30. Few, but skipping this topic is a missed opportunity for easy marks.
- Are there scenario-based questions in the STS exam?
- STS theoretical exams may include situational questions that show how principles apply in real-world contexts.
