PPL Human Performance and Limitations study guide
PPL Human Performance and Limitations · Work through your exam, one topic at a time.
Human Performance and Limitations (HPL) is the ground-school subject that explains how the human in the cockpit - not the aircraft - limits and shapes flight safety. It is a required knowledge area for the European PPL, and the same body of knowledge underpins ATPL and CPL training, so the material you learn here is reused throughout a professional career. The PPL Human Performance and Limitations study guide has 7 sections and about 1,623 words.
01Human Factors: Basic Concepts and Aviation Physiology
Domain 1 tests how human limitations interact with aviation systems, not just isolated physiology facts. Expect questions on the SHELL model, accident causation, error, arousal, and fitness to fly.
245 words, about 1 min02Basic Aviation Physiology and Health Maintenance
Domain 2 tests the body in the flight environment: hypoxia, hyperventilation, gas laws, barotrauma, decompression sickness and health maintenance. Questions often ask for the first action or the distinguishing sign.
249 words, about 1 min03Basic Aviation Psychology
Domain 3 tests attention, workload, vigilance, perception, memory, learning, personality, motivation and stress. The exam favours applied questions: which psychological limit explains this error, and what countermeasure reduces it?
212 words, about 1 min04Sensory Systems and Spatial Disorientation
Domain 4 tests vision, the vestibular system and the illusions that cause spatial disorientation. The exam expects you to recognise the illusion and state the correct response: trust instruments, not sensations.
249 words, about 1 min05Cognition, Decision Making and Error Management
Domain 5 tests information processing, judgment, decision making and error. Expect questions on heuristics, bias, error types and structured decision models such as DECIDE.
216 words, about 1 min06Human Behaviour, Communication and Crew Resource Management
Domain 6 tests teamwork, communication, personality, leadership, assertiveness and CRM. The exam asks how behaviour affects safety and what phrase or action improves the team.
205 words, about 1 min07Aviation Safety Concepts and Threat and Error Management
Domain 7 tests safety models, just culture and Threat and Error Management (TEM). Expect questions on the accident pyramid, SMS, threat, error and undesired aircraft state (UAS).
