Thirteen exams. Six sittings. Eighteen months. Four attempts per paper.
Miss any one of those numbers and EASA voids every pass you hold — you start the whole set again. The limits live in one short rule, FCL.025 of Part-FCL, and misreading it has ended more ATPL runs than any Meteorology paper.
Here is what the rule actually says, in plain language.
Where the EASA ATPL exam rules come from
FCL.025 sits in Regulation (EU) No 1178/2011 — the Part-FCL rules that govern flight crew licensing across all EASA member states. It applies identically whether you sit your exams in Switzerland, the Netherlands, Austria or anywhere else in the system.
Two conditions apply before any limit matters:
- One authority. You must take the entire set of 13 examinations under the responsibility of a single competent authority. You cannot pass six subjects in one country and finish the rest in another.
- ATO recommendation. You only sit when the approved training organisation responsible for your theory course recommends you — that is, once you have completed the relevant training elements to a satisfactory standard.
Limit 1: the 18-month window
You must pass all 13 papers within 18 months. The detail most students miss is when the clock starts: at the end of the calendar month of your first attempt — not on exam day, and not when you finish your course.
Sit your first paper on 5 March 2027 and the window opens on 31 March 2027. Your deadline for the final pass is 30 September 2028.
The clock never pauses. Illness, work, a house move — none of it stops the 18 months.
Limit 2: six sittings
A sitting is a block of consecutive examination days defined by your competent authority — many authorities use a period of up to ten days. Within one sitting you may attempt as many of the 13 papers as you like, but attempting even a single paper consumes one full sitting.
Six is the ceiling, not the plan. Well-organised candidates use three or four and keep the rest in reserve.
Limit 3: four attempts per subject
Each individual paper carries a maximum of four attempts. Fail the same subject a fourth time and the consequence is not a fifth try — it is the loss of every pass you have accumulated.
What happens if you bust a limit
FCL.025(b) is blunt: fail one paper four times, run out of sittings, or run out the 18-month clock, and you must retake the complete set of examination papers. Before you can, you need further training at an ATO — and your competent authority decides how much.
The pass mark is 75% per paper, and there is no negative marking. A wrong answer costs nothing more than a blank one, so answer every question, every time.
How long your passes stay valid
Passing is not the end of the timeline. A completed set of ATPL theory credits is accepted:
- for the issue of a CPL or an instrument rating, for 36 months from the date you complete the examinations;
- for the issue of an ATPL, for 7 years from the last validity date of an IR entered in your licence.
Keep an instrument rating alive and your theory credit effectively rolls forward. Let everything lapse and the 7-year clock becomes very real.
The question bank moved: ECQB 2026
The exams draw on the European Central Question Bank (ECQB), and it is a moving target. The latest revision, ECQB 2026, rolled out to member-state authorities in spring 2026 — Austro Control, for example, switched over on 31 March 2026 — bringing amended and newly written questions.
The lesson for your ATPL exam preparation: memorising stale question dumps is a strategy with a shelf life. Understand the principle behind each answer and a bank update costs you nothing.
Plan your sittings like fuel reserves
Treat six sittings the way you treat fuel: the legal maximum is not the plan. A typical modular split runs three blocks — for example 4 + 5 + 4 papers grouped by subject affinity — leaving two sittings in reserve for retakes and for life getting in the way.
Book your first sitting only when your mock scores sit comfortably clear of the 75% line — consistently around 85% or better. And remember: the 18-month clock starts with paper one, ready or not.
FAQ: EASA ATPL exam rules
How many sittings are allowed for the EASA ATPL exams?
A maximum of six sittings, and all 13 papers must be passed within 18 months of the end of the calendar month of your first attempt. A sitting is a block of consecutive exam days defined by your competent authority.
When does the 18-month ATPL exam period start?
At the end of the calendar month in which you make your first examination attempt — not on the exam day itself, and not when your theory course finishes.
What happens if I fail an ATPL exam four times?
All of your passes are voided and you must retake the complete set of papers after further training at an ATO. Your competent authority determines the scope of that additional training.
How long are ATPL theory exam passes valid?
For 36 months for CPL or IR issue, counted from completion of the exams. For ATPL issue, the credit remains valid for 7 years from the last validity date of an IR entered in your licence.
