ATPL Human Performance and Limitations

It is where careful candidates lose marks.48 questions. 90 minutes. 75% to pass. Half the Subject 040 paper is physiology and numbers - thresholds, times of useful consciousness, G limits, alcohol rules. The other half turns on precise definitions, and the wrong options are usually right ideas wearing the wrong label. Common sense picks the familiar word. The examiner wants the defined one.ATPL Human Performance and Limitations is a complete revision guide and question bank for the EASA and UK CAA airline transport pilot licence theory examination, written by an airline captain and Chief Flight Instructor, and built on all 362 published learning objectives for Subject 040.What is insideWhere the marks are, on one page. The published question distribution set against the syllabus, so you revise in the order that pays.232 practice questions with worked explanations - 184 through the chapters, plus a 48-question mock examination paper weighted exactly as the real paper is, and built only from objectives the chapters did not test. No question is asked twice.Every number sourced. Each chapter ends with Numbers you must own, sorted by where the figure comes from: the syllabus itself, Part-MED, EASA guidance, the UK CAA, or conventional teaching.The confusable pairs and Traps, and why they work in every chapter: slip and mistake, acute and chronic stress, TUC and EPT.On the day. One real flight per chapter, running the theory through an actual operation.20 clear diagrams drawn for this book: the oxygen dissociation curve, the circadian rhythm, the Swiss cheese model and SHELL.Self-check pages, an 89-term glossary and a full index.Nine chapters covering the whole syllabus: competence, threat and error management, SHELL, safety culture and SMS; hypoxia, hyperventilation, decompression sickness, acceleration and carbon monoxide; vision, hearing, the vestibular system and the approach illusions; the body clock, sleep, jet lag, alcohol, medication and incapacitation; information processing, memory and learning; human error, situation awareness and decision-making; crew resource management, leadership and communication; personality, stress, arousal, fatigue and fatigue risk management; and automation, mode awareness and complacency.Written for the paper you are actually sitting. The main text follows the EASA rules, and boxes marked UK give the UK position where it differs - Part-MED and the UK criminal alcohol limit for flight crew.Beyond the EU and UK. Written to the EASA ATPL(A) learning objectives, which also underpin the ATPL theory examinations of the United Arab Emirates (GCAA), Qatar (QCAA), Oman, Türkiye (SHGM), Singapore (CAAS), Malaysia (CAAM), Hong Kong (CAD), Sri Lanka (CAASL), Thailand (CAAT) and Pakistan (PCAA). A page at the front shows the paper this book serves with each authority and what to add from local sources. It also serves the related SACAA (South Africa) and DGCA (India) papers.A revision guide, not a course of training: enrolment with an Approved Training Organisation remains a legal prerequisite for the examinations. It contains no questions from any question bank - every question was written for this book. It is not medical advice.One of fourteen books in the Mastering ATPL series, one for each ATPL(A) theory subject, all written to the same pattern.
