Practice questions for the Boeing 787 Dreamliner with GE GEnx engines, organised by ATA chapter. Covers the more-electric airframe, the Common Core System, and the GEnx-1B powerplant. Sample questions are free to view; the full timed quiz needs a subscription.
Every ATA chapter of the 787 type course — airframe, avionics, hydraulics, environmental control, structures and the powerplant.
The GE GEnx high-bypass turbofan: its FADEC engine controls, indicating, ignition and starting, oil and exhaust systems.
Per-chapter timed practice with weak-area tracking; retake as often as you like.
The Boeing 787 Dreamliner is a long-range, widebody twinjet and the first Boeing airliner with a more-electric architecture, a composite fuselage, and fly-by-wire flight controls. This question bank follows a 787 type-rating and continuation-training course, organised by ATA chapter so revision maps directly onto the maintenance documentation.
Coverage spans the full systems syllabus: the electrical power system and the Common Core System (CCS) computing backbone, communications and navigation, autoflight and thrust management, hydraulics and the flight-control system, fuel, the nitrogen-generation/inert-gas system, fire protection and the APU, air conditioning and pressurisation, ice and rain protection, landing gear, structures, equipment, oxygen, doors and windows. The powerplant chapters address the GE GEnx turbofan — its full-authority digital engine control (FADEC), indicating, ignition and starting, air, oil and exhaust systems.
Suitable for initial type-rating preparation or recurrent knowledge checks.
Sample questions below are drawn live from the Boeing 787 (GEnx) question bank of 4 423 questions across 34 ATA chapters. The full timed practice quiz is per-chapter and needs an active subscription.
One per chapter, spread across the type. Click "Reveal answer" after you've picked.
Sign up, open the Boeing 787 (GEnx) chapter grid, and run a timed practice quiz on any ATA chapter from the 4 423-question bank. Your score is tracked across attempts and weak areas are surfaced so revision time pays off.
Yes. Every quiz question, all of its answer options and the written explanation can be read in 13 languages besides English — Chinese (Traditional), French, German, Greek, Hindi, Italian, Norwegian, Polish, Portuguese, Romanian, Russian, Spanish and Turkish. It is included for every signed-in member at no extra cost, and you can switch language in the middle of a quiz without losing your answers or your timer.
The English original stays one click away on every question, which is the point: the EASA Part-66 examination is sat in English, so you can read a question in your own language, answer it, then switch it back to English to check yourself against the wording you will actually meet.
Two caveats worth knowing. It is machine translation — checked so that no two answer options drift into meaning the same thing and that numerals and units survive intact, but it is not a human technical translation. And technical designations such as A320, LEAP-1A, Part-145, CS-25 and ATA chapter numbers are deliberately left in English, because those are the strings on the aircraft, in the manual and on the exam paper. Translation covers the quizzes; the study notes and reference pages are in English.
