ATPL Instrumentation

Instrumentation is the subject whose name no longer describes it. Candidates revise the dials, and the paper asks about the automation. 60 questions. 90 minutes. 75% to pass. Subject 022 asks 409 learning objectives for 60 marks. The marks are not where the objectives are: the autopilot, autothrust, protections and flight management system carry 24 of the 60. ATPL Instrumentation 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 409 learning objectives for Subject 022. It teaches the failure by teaching the mechanism. Every blocked pitot and misread mode is reasoned from how the system works. Where the syllabus uses two names for one thing — MCP and FCU, EICAS and ECAM — the book gives both. The calculations use one invented medium-range jet; the examination gives its own data, and the method is identical. What is inside Where the marks are, on one page: autothrust pays a mark for every 2.3 objectives, the engine instruments need 14.7. 341 practice questions with worked explanations — 281 through the chapters, plus a 60-question mock examination paper weighted exactly as the real paper is, built only from objectives the chapters did not test. No question is asked twice. The confusable pairs and Traps, and why they work in every chapter: CAS and EAS, armed and engaged, fail-passive and fail-operational. On the day. One flight per chapter, running the systems through a real operation. 81 clear diagrams drawn for this book: the pitot-static system and its blockages, the flight mode annunciator and autoland. Every figure sourced, in Numbers you must own**. A glossary and a 212-entry index. ** Eleven chapters covering the whole syllabus: engine instruments; pitot-static systems and altimetry; airspeed and the air-data computer; compasses and gyros; inertial navigation; the autopilot and autoland; envelope protection and autothrust; data link and recorders; flight management systems; alerting systems; and electronic displays. Written for the paper you are actually sitting. The book follows the 2026 EASA syllabus and the rules now in force, and says plainly where older textbooks differ: CS-AWO Issue 2 and its definitions of fail-passive, fail-operational and hybrid landing systems; and the data-link rule that a route clearance is loaded and checked before WILCO, not after. 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 or a type rating: enrolment with an Approved Training Organisation remains a legal prerequisite. It contains no questions from any question bank — every question was written for this book. Its aeroplanes and data are fictional, and your aircraft's flight manual and operating procedures always take precedence. One of fourteen books in the Mastering ATPL series, one for each ATPL(A) theory subject, all written to the same pattern.
