Overview: How the ATM Test Maps to the ACS
The Airline Transport Pilot Multiengine Airplane (ATM) knowledge test isn't organized around loose topic lists - it's built directly from the Areas of Operation in FAA-S-ACS-11A, effective May 31, 2024. The FAA and PSI translate those Areas of Operation into eight testable domains, and every one of the 125 scored questions on your exam traces back to one of them. Understanding this structure is the single biggest advantage you can give yourself before test day, because it tells you exactly what to study and in what proportion.
If you haven't already reviewed the mechanics of the exam itself - question count, timing, fee, and eligibility - start with our ATP Study Guide 2026: How to Pass on Your First Attempt before diving into domain-by-domain prep. This article assumes you already know you need the ATP-CTP graduation certificate to sit for the test and focuses purely on what's actually being asked.
Domain 1: Preflight Preparation
Preflight Preparation is the knowledge-heavy front end of the ATM test. This domain covers the regulatory and planning material a captain must internalize before ever touching the throttles: weight and balance for multiengine turbine aircraft, performance charts, weather interpretation, NOTAMs, dispatch releases, and the regulatory framework under 14 CFR Part 121 and Part 91 that governs airline-level operations.
Preflight Preparation
Candidates must correctly apply performance data and regulatory limits before a flight is ever dispatched.
- Reading and interpolating takeoff and landing performance charts
- Weight and balance calculations for transport-category aircraft
- Weather products: METARs, TAFs, winds aloft, significant weather charts
- Crew duty time, rest requirements, and dispatch documentation
Expect scenario-based questions that give you a chart or table and ask you to compute a value, not just recall a definition. This is a pattern that repeats throughout the ATM test and is discussed in more depth in How Hard Is the ATP Exam? Complete Difficulty Guide 2026.
Domain 2: Preflight Procedures
Where Domain 1 tests planning knowledge, Preflight Procedures tests the operational sequence: crew briefings, systems checks, and the coordination required in a multiengine turbine cockpit before pushback. This domain draws heavily on the crew resource management (CRM) concepts introduced during the classroom portion of ATP-CTP.
Preflight Procedures
Focuses on cockpit setup, crew coordination, and system verification prior to taxi.
- Crew briefings and division of duties between pilot flying and pilot monitoring
- Engine start sequences and systems checks specific to turbine aircraft
- Use of checklists in a two-pilot, multiengine environment
- Threat and error management concepts from CRM training
Because ATP-CTP requires at least 30 hours of classroom instruction, much of this domain's content comes straight from that curriculum rather than from general aeronautical knowledge study materials.
Domain 3: Takeoffs and Landings
This domain tests your understanding of takeoff and landing procedures in multiengine turbine airplanes, including the decision points and speeds that separate transport-category operations from smaller aircraft. Expect questions on V-speeds (V1, VR, V2), rejected takeoff decision-making, crosswind technique, and stabilized approach criteria.
- V-speed definitions and their operational significance
- Balanced field length and accelerate-stop distance concepts
- Stabilized approach criteria and go-around decision points
- Contaminated runway and crosswind performance considerations
Key Takeaway
Memorize the V-speed hierarchy (V1, VR, V2) and what decision each one represents - this shows up repeatedly across Domain 3 and Domain 7 questions.
Domain 4: In-flight Maneuvers
In-flight Maneuvers covers the handling characteristics and procedures unique to multiengine turbine aircraft during climb, cruise, and descent phases. This includes engine-out flight dynamics, which is a defining difference between single-engine and multiengine ATP knowledge.
In-flight Maneuvers
Tests understanding of aircraft control and performance during normal and asymmetric-thrust flight.
- Engine-out performance and directional control principles
- Steep turns and maneuvering limitations at high altitude
- Effects of Mach number and high-speed flight characteristics
- Autopilot and flight director interaction during maneuvers
High-altitude aerodynamics questions often trip up candidates who studied primarily from piston-aircraft materials. If this domain feels unfamiliar, revisit the turbine-specific portions of your ATP-CTP simulator training before test day.
Domain 5: Stall Prevention
Stall Prevention exists as its own domain because of the industry-wide emphasis on upset prevention and recovery training (UPRT) following several high-profile stall-related accidents. Questions here test your understanding of approach-to-stall indications, angle-of-attack awareness, and the correct recovery technique in swept-wing turbine aircraft - which differs from traditional "pitch and power" recovery taught in earlier certificates.
- Recognizing approach-to-stall warnings (stick shaker, aural alerts, buffet)
- Correct recovery priority: reduce angle of attack before adding power
- High-altitude stall characteristics and reduced margins
- Stall recovery in a swept-wing, high-bypass turbofan context
Domain 6: Instrument Procedures
Instrument Procedures is one of the densest domains on the ATM test, covering IFR departure and arrival procedures, holding, approach categories, and the interpretation of complex instrument charts in a transport-category context.
Instrument Procedures
Requires fluent chart-reading and procedural knowledge under IFR in a multi-crew environment.
- Standard instrument departures (SIDs) and standard terminal arrivals (STARs)
- Approach category speeds and minimums for turbine aircraft
- RNAV and RNP approach procedures
- Holding pattern entries and timing at high true airspeeds
Chart-reading questions in this domain are among the most time-consuming on the test, so pacing matters. Since the ATM exam gives you 3 hours and 30 minutes for 130 total questions, budget extra time for Domain 6 items during your first pass and flag anything that requires careful chart cross-referencing.
Domain 7: Emergency Operations
Emergency Operations tests your knowledge of abnormal and emergency procedures specific to multiengine turbine airplanes: engine failures, fires, pressurization loss, and system malfunctions. This domain overlaps conceptually with Domain 3 and Domain 4 but focuses specifically on the decision trees pilots follow when something goes wrong.
- Engine failure procedures during takeoff, climb, and cruise
- Rapid decompression and emergency descent procedures
- Fire, smoke, and fumes checklists
- System redundancy and single-point-of-failure reasoning
Because these scenarios are also drilled extensively during the 10 hours of simulator time required by ATP-CTP, candidates who paid close attention during their simulator sessions often find this domain more intuitive than pure book study would suggest.
Domain 8: Postflight Procedures
The final domain, Postflight Procedures, is the smallest in scope but still appears on the test. It covers shutdown procedures, post-flight documentation, and the reporting requirements that follow a completed flight, including maintenance write-ups and irregularity reports.
Postflight Procedures
Covers the administrative and procedural close-out of a flight.
- Engine shutdown sequences and securing procedures
- Logbook and maintenance discrepancy reporting
- Post-flight crew debrief practices
- Documentation requirements under Part 121 operations
Don't skip this domain just because it's less glamorous than engine-out maneuvers - every domain contributes scored questions, and the ACS codes on your test report don't discriminate between "exciting" and "administrative" content.
Scheduling Your Prep Around the Eight Domains
A generic study calendar won't help you here - your schedule should mirror the density and difficulty of each domain. Preflight Preparation and Instrument Procedures tend to require the most raw study time because of their chart-reading and calculation components, while Postflight Procedures typically needs only a light review pass.
Domains 1 & 2
- Master weight/balance and performance chart interpolation
- Review CRM and crew briefing sequences
Domains 3 & 4
- Drill V-speeds and takeoff/landing decision points
- Study engine-out and high-altitude maneuvering concepts
Domains 5 & 6
- Practice modern stall recovery technique repeatedly
- Work through SID/STAR and approach chart scenarios
Domains 7 & 8, then full review
- Run through emergency checklists and decision trees
- Review postflight documentation and take full-length timed practice sets
This kind of domain-weighted approach is more effective than working straight through a question bank in random order, because it forces you to notice which of the eight domains is genuinely weak versus which one you've simply seen fewer questions on. For a deeper breakdown of study methodology tied specifically to ATP content, see our full ATP Study Guide 2026.
| Domain | Primary Focus | Question Style |

Who Actually Tests on These Domains
The ATM test isn't an academic exercise - it's the gateway knowledge test for pilots pursuing an unrestricted Airline Transport Pilot certificate with a multiengine rating, which is required for captain and, at most carriers, first officer positions flying transport-category aircraft. Regional airlines, cargo operators, and fractional/charter operations flying multiengine turbine equipment all expect this credential as a baseline. If you're evaluating whether the full certification path makes sense for your career trajectory, our articles on ATP Jobs and Is the ATP Certification Worth It? Complete ROI Analysis 2026 break down where this credential actually opens doors.
It's also worth understanding the cost structure before you schedule your test date. Beyond the $175 PSI testing fee, you'll have already invested in the ATP-CTP program itself. Our ATP Certification Cost 2026: Complete Pricing Breakdown article lays out the full financial picture so there are no surprises.
Reading Your Score Report by Domain
When you finish the 130-question exam, your Airman Knowledge Test Report will show a pass/fail result against the 70% passing threshold along with ACS codes tied to any of the eight domains where you missed questions. This is the single most useful diagnostic tool available to you if you need to retest, because it eliminates guesswork about where your knowledge gaps actually are. For a full explanation of how the scoring threshold works and what counts toward your 70%, see ATP Passing Score 2026: Exactly What You Need to Pass.
Since a passing result on the ATM test remains valid for 60 calendar months, many candidates strategically time their knowledge test relative to their planned checkride and hiring timeline. If scheduling logistics are unclear, our ATP Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide covers how to book with PSI and what lead time to expect.
Running full-length, timed practice sessions that mirror the real 125-scored/5-unscored question structure is the most reliable way to confirm domain-by-domain readiness before you pay the $175 fee. You can build that familiarity using the timed practice exams on our main practice test platform, which mirror the ACS domain breakdown covered in this guide.
Frequently Asked Questions
The FAA does not publish a fixed percentage breakdown per domain for the ATM test. Instead, questions are drawn from the ACS Areas of Operation, and your score report shows ACS codes for any domain where you missed questions, regardless of how many total questions came from that area.
Yes. Because the 125 scored questions are pulled from across all eight domains, skipping study on any one area - even a smaller one like Postflight Procedures - leaves scored questions on the table unnecessarily.
The ATM test expects the modern approach-to-stall recovery technique - reducing angle of attack first, before adding power - which reflects updated industry standards taught during ATP-CTP rather than the older "pitch and power" method some pilots learned earlier in training.
No. Applicants must present a graduation certificate from an authorized Airline Transport Pilot Certification Training Program, which includes at least 30 hours of classroom instruction and 10 hours in a qualified multiengine-turbine flight simulation training device, before testing.
A passing result on the ATM knowledge test is valid for 60 calendar months, so plan your certification timeline and checkride scheduling accordingly.
Mastering all eight ATM domains - Preflight Preparation, Preflight Procedures, Takeoffs and Landings, In-flight Maneuvers, Stall Prevention, Instrument Procedures, Emergency Operations, and Postflight Procedures - is the clearest path to walking into your PSI test session with confidence rather than guesswork.
