Building an Aviation Question Bank Structured by ATA Chapter
An aviation exam question bank is a managed set of exam items, each tagged so the right questions reach the right exam. For a maintenance training organization, the most useful tag is often the ATA chapter, the industry’s number for an aircraft system, because syllabus headings and technical manuals already use it. This post shows how to build that structure.
Most search results for this topic sell practice questions to candidates. This post is for the people on the other side of the exam: heads of training, quality managers and exam officers at maintenance training organizations and aviation training departments who have to build, defend and maintain their own item banks.
Nothing in the regulations we checked requires a bank to be arranged by ATA chapter. That is a design choice. The rules do set limits that shape the design, and we separate the two below. Regulatory facts are as of October 2026. This is not legal or airworthiness advice, so check your competent authority before you rely on any number here.
Key takeaways
- An ATA chapter is a good primary tag for systems questions because EASA’s Part-66 syllabus headings and type-training chapter tables use the same numbers.
- Questions used in a multimedia-based training (MBT) learning programme may not be used in examinations, so every item needs a purpose field that the exam pool can filter on.
- For type exams, the minimum is one question per hour of training, split across chapters and levels in proportion to teaching hours and learning objectives.
- Keep the ATA chapter, the regulator’s own syllabus reference and the knowledge level as three separate fields so one bank can serve EASA and FAA courses.
What is an aviation exam question bank, and who should build one?
An aviation exam question bank is a controlled set of exam items, each with an ID, a syllabus reference, a knowledge level, a status and a history. A training organization builds its own when it must assemble many different exams from the same material, show coverage to its authority, and keep items current as manuals change.
Based on a read of the ten results returned for “aviation exam question bank” in October 2026, nine are commercial banks or listings for candidates who are revising, and one is EASA’s page on its central bank for flight crew exams. The commercial ones offer subject codes, explanations and mock exams. None explained how a training organization should structure, govern or version a bank of its own.
What do the rules say about structuring an aviation exam question bank?
The rules we checked set limits on examinations, not a bank layout. As of October 2026, Regulation (EU) 2023/989 sets how basic exams may be split, caps attempts, bars learning-programme questions from exams and sets a minimum question count for type exams. How the bank is organized inside is left to the organization.
The table separates what the text requires from what it leaves to you. The citations are to Annex III (Part-66) as amended by Commission Implementing Regulation (EU) 2023/989, which applies from 12 June 2024.
| Rule (as of October 2026) | Where it sits | What your bank needs |
|---|---|---|
| Learning questions stay out of exams | Appendix II point 1.14 says MBT learning programme questions “shall not be used in examinations”; Appendix III point 4.1(j) says “shall not be used in course or phase examinations” (quoted) | A purpose field, and an exam pool that cannot select learning items |
| Type exam size | Appendix III point 4.1(f): “The number of questions shall be at least one question per hour of training” (quoted), proportionate by chapter and level to teaching hours and learning objectives; the competent authority assesses number and level when approving the course | A quota per chapter and level, and enough items to fill each quota |
| Partial exams | Appendix II point 1.12: longer basic exams may be split; each partial exam must be passed with “75 % or more of the questions answered correctly” and “contain a number of questions that is multiple of four” (quoted) | Draw sizes that can be set in multiples of four |
| Attempts | Appendix II point 1.13: “The maximum number of attempts for each examination is three in a 12-month period” (quoted) | Attempt records kept outside the bank; how retake forms differ is your policy, not a rule we found |
Two limits apply. Your authority may expect more when it approves a course, and module numbering and syllabus text can change. The regulations do not approve or certify assessment software, so no bank layout makes a tool compliant on its own.
Pro tip: Make The Exam And Learning Split A Database Rule. Tag every item with a purpose when it is created, and build exam draws that cannot select learning items. Relying on authors to remember fails the first time someone copies an item between courses.
Why use ATA chapters as the spine of an aviation exam question bank?
ATA chapters are the industry’s numbers for aircraft systems, such as 21 for air conditioning and 32 for landing gear. Airlines for America publishes the scheme inside iSpec 2200. Part-66 syllabus headings and type-training chapter tables use these numbers, so a bank tagged by chapter lines up with your manuals and your syllabus.
Airlines for America describes iSpec 2200 as a global standard for the content, structure and electronic exchange of aircraft engineering and maintenance information, and says it includes the industry-wide standard for numbering aircraft systems. In Regulation (EU) 2023/989, Part-66 Appendix I headings carry ATA numbers, for example “11.11 Hydraulic power (ATA 29)” and “11.13 Landing gear (ATA 32)” (quoted).
The Appendix III type-training table is organized in numbered chapters too. The 2023/989 amendment inserted “chapter 47” after chapter 46 under “Airframe systems” (quoted). So one chapter number can label a syllabus row and a bank item, and usually the matching manual section.
Where do ATA chapters fall short as a bank structure?
ATA chapters fall short in three places. Some topics are not systems, one question can touch several systems, and not every authority uses ATA numbers. A bank that ignores these gaps ends up with blank tags, double counting or items that cannot be reported against the right standard.
- Non-system topics. Part-66 basic modules such as Mathematics and Human Factors carry no ATA references in the Appendix I headings we read. Give those items an explicit “not applicable” value, never a blank.
- Cross-system questions. Allow one primary chapter and at most one secondary chapter.
- Other authorities. The FAA’s mechanic standards use their own codes. The AMT Airman Certification Standards (FAA-S-ACS-1) list codes such as “AM.I.A.K1”, and the edition we read, dated November 2021, did not refer to ATA chapters. A US school needs the ACS code as its own field.
Which fields should every item in an aviation exam question bank carry?
Give each item nine fields: ID, primary ATA chapter, secondary ATA chapter, syllabus reference, knowledge level, aircraft applicability, purpose, status and source reference. The syllabus reference points to the regulator’s own heading, and the ATA chapter points to your manuals. Together they let you show coverage and find affected items fast.
The table gives an example value for each field. The examples are invented and carry no exam content.
| Field | Example value | Why it matters |
|---|---|---|
| Item ID | AV-00412, permanent and never reused | Statistics and history follow the item |
| Primary ATA chapter | 29 | Drives coverage reports and exam draws |
| Secondary ATA chapter | 36, or “none” | Records genuine cross-system items without double counting |
| Syllabus reference | Part-66 Appendix I 11.11, an Appendix III chapter, or an ACS code | Ties the item to the authority’s own wording |
| Knowledge level | Level 2 | Appendix III sets levels 1 to 3 for type training; items should match the level taught |
| Aircraft applicability | Aircraft type and series | Stops an item for one variant reaching another variant’s exam |
| Purpose | Exam or learning check | Enforces the exam and learning split |
| Status | Draft, reviewed, live, under review, retired | Controls what the exam pool can see |
| Source reference | Manual and revision the key was checked against | Shows which items a manual change affects |
Tag values should come from fixed lists with written definitions. The post on building an item bank for a training company covers keeping tags consistent across authors and when an edit creates a new version. Item writing quality is a separate job, covered in the sibling post on writing aviation MCQs that test understanding.
Pro tip: Store The Manual Revision, Not Just The Chapter. When a manufacturer revises a manual, filter the bank by chapter and aircraft applicability, then send every item whose stored source revision is older to review. Without that field you re-read the whole chapter.
How do ATA chapters map to EASA modules and FAA subjects?
An ATA chapter usually maps to one Part-66 Appendix I sub-module and one FAA mechanic subject, though not always one to one. The table pairs nine chapters with the heading printed in Regulation (EU) 2023/989 and the closest Airframe subject in the FAA’s AMT Airman Certification Standards. The FAA column is our editorial match, so have experts confirm it.
| ATA chapter | Part-66 Appendix I heading (Module 11, as printed in 2023/989) | FAA ACS Airframe subject (closest match) |
|---|---|---|
| 21 | 11.4 Air conditioning and cabin pressurisation (ATA 21) | G. Environmental Systems |
| 24 | 11.6 Electrical power (ATA 24) | K. Aircraft Electrical Systems |
| 26 | 11.8 Fire protection (ATA 26) | M. Airframe Fire Protection Systems |
| 27 | 11.9 Flight controls (ATA 27) | C. Flight Controls |
| 28 | 11.10 Fuel systems (ATA 28, ATA 47) | J. Aircraft Fuel Systems |
| 29 | 11.11 Hydraulic power (ATA 29) | F. Hydraulic and Pneumatic Systems |
| 30 | 11.12 Ice and rain protection (ATA 30) | L. Ice and Rain Control Systems |
| 32 | 11.13 Landing gear (ATA 32) | E. Landing Gear Systems |
| 36 | 11.16 Pneumatic/vacuum (ATA 36) | F. Hydraulic and Pneumatic Systems |
Chapters 29 and 36 share one FAA subject, and the Part-66 heading for fuel lists two chapters. That is why the bank keeps the ATA chapter and the syllabus reference as separate fields. Module numbers and titles here are as printed in 2023/989, so check the current consolidated text before you publish a mapping.
How many questions should each ATA chapter get in a type exam?
A type exam needs at least one question per hour of training, split across chapters and levels in proportion to teaching hours and learning objectives. That is the Appendix III rule as amended by Regulation (EU) 2023/989, and the competent authority assesses the number and level when approving the course. The worked example shows the arithmetic.
Assume a 60-hour type theory course. The hours per chapter are invented for the example and do not describe a real course.
Step 1: Set the floor. Sixty hours of training means at least 60 questions.
Step 2: Choose the paper size. We choose 80 questions so each chapter has a usable sample. That is a design choice, not a rule.
Step 3: Allocate by hours. 80 questions across 60 hours gives 1.33 questions per hour, so a 4-hour chapter earns 5.33 questions.
Step 4: Round to whole questions. Round down, then give the leftover questions to the largest remainders, using more teaching hours as the tie-breaker. The paper still totals 80.
Step 5: Size the bank. One worked example in our exam security settings checklist keeps each area at three times its draw. Apply that as a starting point, then adjust it.
| ATA chapter | Illustrative hours | Share of hours | Questions on an 80-question paper | Bank target at 3 times the draw |
|---|---|---|---|---|
| 05 to 12 General | 4 | 6.7% | 5 | 15 |
| 21 Air conditioning | 4 | 6.7% | 5 | 15 |
| 24 Electrical power | 8 | 13.3% | 11 | 33 |
| 27 Flight controls | 6 | 10.0% | 8 | 24 |
| 28 Fuel | 4 | 6.7% | 5 | 15 |
| 29 Hydraulic power | 4 | 6.7% | 5 | 15 |
| 32 Landing gear | 6 | 10.0% | 8 | 24 |
| 36 Pneumatic | 3 | 5.0% | 4 | 12 |
| 72 Engine | 14 | 23.3% | 19 | 57 |
| 73 Engine fuel and control | 7 | 11.7% | 10 | 30 |
| Total | 60 | 100% | 80 | 240 |
Repeat the calculation for each level where a chapter is taught at more than one. The table is a planning aid. If your authority assesses question numbers differently, follow the authority.
What should you do when a manual or the rules change?
Treat any manual revision or regulatory amendment as a trigger to review the affected items, not the whole bank. Filter by ATA chapter and aircraft applicability, compare each item’s stored source revision, and move stale items to under review so they leave the exam pool until an expert re-checks the key.
Statistics help but do not decide. The item analysis guide for trainers explains which flags to act on. On the regulatory side, EASA’s Easy Access Rules for Continuing Airworthiness showed a September 2025 revision as of October 2026. Confirm which text applies to your courses with your competent authority.
What should you do next?
Start with one type course. List its chapters and hours, build the quota table above, and ask your instructors to tag 100 existing items with the nine fields. The chapters where the bank is thinner than its target show where to write items first.
If you are comparing platforms, ask each vendor to show these fields working. SimpliAssess’s features page lists Item Banking, Tag Management and Bulk Import as headings without describing them, so confirm in a demo that tags can hold the fields in this post. SimpliTrain’s question bank page says it tags every item with topic, competency, difficulty level and question type and supports QTI import and export.
Neither page mentions ATA chapters, and a feature list does not show that a tool meets any authority’s requirements.
Frequently asked questions
Do EASA rules require an aviation exam question bank to be organized by ATA chapter?
No. In the texts we checked, Regulation (EU) 2023/989 uses ATA numbers in Part-66 Appendix I headings and in chapter tables, but it does not tell an organization how to arrange its bank. A chapter-based structure is a design choice that helps you show coverage. Ask your competent authority what evidence it expects when it approves a course.
What is an ATA chapter?
An ATA chapter is a number that identifies an aircraft system or section, such as 21 for air conditioning, 29 for hydraulic power or 32 for landing gear. The scheme began with the Air Transport Association and is now part of iSpec 2200, published by Airlines for America. EASA syllabus headings use these numbers too.
How many questions should an aviation exam question bank hold?
The texts we read set no bank size. They set exam sizes, such as at least one question per hour of training for type exams. Plan the bank from the draw instead. One worked example in our exam security checklist keeps each area at three times its draw. Treat that as a starting point and adjust it with item statistics.
Should I tag a question with more than one ATA chapter?
Use one primary chapter and, where a question genuinely spans two systems, one secondary chapter. Report coverage on the primary chapter only, so each question counts once. More tags make coverage reports hard to read and encourage authors to tag everything, which weakens the filter the structure was meant to give you.
Can I reuse learning-check questions in the final exam?
Not if they belong to a multimedia-based training (MBT) learning programme under the rules we read. Appendix II point 1.14 and Appendix III point 4.1(j) of Part-66, as amended by Regulation (EU) 2023/989, bar those questions from examinations. For other kinds of learning check, confirm with your competent authority before you reuse them.
Does the FAA use ATA chapters for mechanic knowledge testing?
The FAA’s AMT Airman Certification Standards, document FAA-S-ACS-1, organize content by subject and element codes such as AM.I.A.K1, and the edition we read did not refer to ATA chapters. A US school can still tag items with ATA chapters to match its manuals, but should keep the ACS code as a separate field.
