Question bank updates

Last updated 25 September 2026. What the practice questions are checked against, how a question is reviewed before students see it, and a dated log of changes to the bank.

Standards in use

Syllabus standards

• CASR Part 61 Manual of Standards — Schedule 3 — Compilation F2025C00050, in force from 19 November 2024. The aeronautical knowledge standards for the RPL, PPL and CPL. Every pilot question cites a Schedule 3 unit and records this compilation as the version it was checked against.
• CASR Part 101 Manual of Standards — Schedule 4 — Compilation F2024C00404 of instrument F2019L00593, as in force on 30 April 2024. The knowledge standards for the Remote Pilot Licence (RePL). Every RePL question cites a Schedule 4 item.
• Part 91 (General Operating and Flight Rules) Manual of Standards — F2020L01514, Compilation No. 8, in force from 9 July 2026. The operating rules that questions point to, such as fuel reserves, supplemental oxygen, overwater equipment and VMC.

The Part 61 and Part 101 compilations were checked against the Federal Register of Legislation on 13 September 2026 and were the current compilations. Questions and explanations also draw on CASR 1998, the AIP and Bureau of Meteorology guidance.

How a question is reviewed

1. Written from the public record. Drafted in our own words from CASR, the Part 61 and Part 101 MOS, the AIP and Bureau of Meteorology guidance. Nothing here is a recalled CASA exam question, and we do not accept them.
2. Checked automatically. A new question stays hidden from students until it passes every check below. The options are shuffled when it is added, so the answer’s position gives nothing away. The checks run again at release, and if one question in a batch fails, none of the batch is released.
   • Four options, none blank and no two the same.
   • An answer key that points at one of those options, and an explanation of real substance.
   • A reference that names a real Part 61 MOS Schedule 3 unit, or for a drone question a real Part 101 MOS Schedule 4 item.
   • The right answer is not the longest option, and it is not the only option carrying a bracketed note.
   • No “all of the above”, “both” or “none of the above” options.
   • No more than three questions from one template (the same question with different numbers) in a subject.
   • Not a copy of a question already in the bank.
3. Enforced by the database. Whatever tool adds or edits a question, the database itself refuses one whose right answer is longer than every other option. The rule also runs when a question is released into exams.
4. A person reads a sample. Since 25 September 2026 a batch is released only after a person has read a random sample of it and passed it: all of a batch of 50 or fewer, otherwise 50 questions or 5% of the batch, whichever is more. Each verdict is logged by name against the exact version that was read, and one failed question, or one marked for a fix, holds back the whole batch. The sample checks what software cannot, such as whether the key is right and the explanation says what the source says; it is not a read of every question. Released questions are served ahead of older imported ones.
5. Every edit is on record. A change made in the question editor is written to a revision log: who made it, when, what changed, and the text before and after. The database will not let anyone alter or delete that log. Bulk repairs are backed up to a snapshot table before they run, so each one can be reversed.
6. Kept current. Every released question records the version of the standard it was checked against, for example “CASR Part 61 MOS F2025C00050”. When CASA amends the MOS, we list the questions it affects and re-check them.

Spotted a mistake?

Use Report Error. It is in the exam toolbar during any exam or drill, beside each question on your results and KDR, and at the bottom of Explain Answer. Choose what is wrong (answer key, reference, typo, diagram or calculation), add a short note and send: the question ID, its reference, the options and your answer are attached automatically. We check each report against the source and correct the question if it is wrong.

Change log

• 25 September 2026 — Every release now needs a logged human sample. A batch of new questions can no longer be released until a person has read a random sample of it and passed it: all of a batch of 50 or fewer, otherwise 50 questions or 5% of the batch, whichever is more. Each verdict is logged under the reviewer’s name against the exact version that was read. If a question changes afterwards, it has to be read again. One failed question, or one marked for a fix, holds back the whole batch until it is corrected and read again. Releases before this date went out on the automated checks, with no person’s read on record.
• 24 September 2026 — 830 CASA questions released after automated checks. 830 new questions (CPL 717, PPL 87, RPL 22, RePL 4) passed every automated check and were released into exams. No record shows that a person read any of them before they were released. Three navigation questions from the fuel-reserve set, held back since 14 September, had answer keys that disagreed with their own working. The keys were recomputed and corrected, and the questions returned. Pending: A person’s read of a random sample of this batch has not been recorded yet. Until it is, these questions are in exams on the automated checks alone.
• 23 September 2026 — Southern Hemisphere corrections. A check for Northern Hemisphere rules in the Australian bank found three questions to correct: one described the wind change at a cold front as a veer (in the Southern Hemisphere it backs), one gave UNOS as the Southern Hemisphere compass rule (it is ONUS), and one used the Northern Hemisphere wording for a warm front in a distractor. The same veer error was corrected in the cold-front item in the Study Hub visual labs. All 6,475 live CASA questions were re-checked for a valid MOS reference; none needed to come out of exams.
• 20 September 2026 — “None of the above” options removed. 12 questions with a “none of the above” option were deleted. Such options are ambiguous and stop making sense when the options are shuffled. The review gate and the release step now reject them.
• 14 September 2026 — Every question cites a real syllabus unit. An audit found that no CASA pilot question cited a real Part 61 MOS Schedule 3 unit. Most used codes such as “NAV 3.2” that do not exist in the MOS. 5,576 questions were re-cited to the Schedule 3 unit that examines them. Question text, options and answers were not changed. The review gate and the question editor now reject any reference that does not name a real unit. A check of the whole bank afterwards found every reference valid.
• 14 September 2026 — The database blocks the longest-answer giveaway. A database rule now refuses any question whose right answer is longer than every other option. It runs on every new question, every change to a question’s options or answer key and every release into exams, whichever tool makes the change.
• 14 September 2026 — Less repetition within a sitting. Questions that differ only in their numbers now count as one template. A new question is rejected if its template already has three questions in that subject, and each exam draws every template once before any template twice.
• 14 September 2026 — Fuel-reserve questions corrected against the Part 91 MOS. The Part 91 MOS (F2020L01514, Compilation No. 8) was added to the reference library so that fuel, oxygen, overwater and VMC references can be checked against its text. 469 questions worked out their answer with a “10% variable reserve” that the Part 91 MOS does not require. They were taken out of exams while they were checked. 466 were corrected and returned. Each stem now gives the Part 91 MOS figure as the rule and states any extra fuel as fuel policy. Every answer key was re-checked against the question’s own figures first, and each change is in the revision log.
• 13 September 2026 — Bank-wide integrity repair. Answer positions were shuffled. The right answer had been option A in 99% of questions; it is now spread about evenly across A to D. The “right answer is the longest option” giveaway was removed from every question in exams. The final pass alone repaired 1,341 questions, mostly by moving the worked calculation out of the answer and into the explanation. 131 questions with two identical options were fixed. In 40 of them the repeated option was the right answer, so they could not be answered. 370 questions printed the working or the rule inside the right answer only. That text was moved to the explanation, which you see after answering. 8 broken imported questions were taken out of exams.
• 13 September 2026 — Drone (RePL) questions released; standards confirmed current. 180 RePL questions, each citing a real CASR Part 101 MOS Schedule 4 item, were released. Before this the RePL bank had no questions in exams. The Part 61 MOS (compilation F2025C00050) and the Part 101 MOS (compilation F2024C00404) were checked against the Federal Register of Legislation and confirmed as the current compilations.
