Differences-based practice questions for engineers and crews moving from the Airbus A320 family to the widebody A330, organised by ATA chapter. Covers the scale-up in systems and the Rolls-Royce Trent 700 powerplant. Samples are free to view; the full quiz needs a subscription.
Chapters concentrate on what changes moving from the single-aisle A320 to the twin-aisle A330 — focused conversion revision.
The Rolls-Royce Trent 700 installation, its controls and indicating — new ground for crews coming off the A320.
Per-chapter timed practice with weak-area tracking, retake as often as you like.
The Airbus A330 is a long-range widebody, and crews and engineers converting from the A320 family study it as a differences type. This question bank follows that course: each chapter concentrates on the differences from the A320 to the A330 — the move from a single-aisle to a twin-aisle aircraft, larger and additional systems, and the long-range operational considerations — rather than re-teaching the shared Airbus fly-by-wire philosophy.
Coverage includes the scaled-up air conditioning and pressurisation, the larger electrical and hydraulic systems, the expanded fuel system, the landing gear and structural differences, and the powerplant. The engine for this course is the Rolls-Royce Trent 700 — a three-shaft high-bypass turbofan that is entirely new ground for personnel coming off the CFM56/V2500-powered A320. Chapters are organised by ATA so the material maps onto the differences-course structure.
Use this for A320-to-A330 conversion training or recurrent checks.
Sample questions below are drawn live from the Airbus A320 to A330 Diff question bank of 2 392 questions across 23 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 Airbus A320 to A330 Diff chapter grid, and run a timed practice quiz on any ATA chapter from the 2 392-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.
