How it works
What’s on the ATM test
Questions come from the knowledge and risk management elements of the Airline Transport Pilot and Type Rating for Airplane Category ACS. Our mock exams spread the 125 questions across its areas in proportion to how many topics each has; the FAA does not publish its exact weighting.
| Area of operation | Topics | Mock exam questions |
|---|---|---|
| I. Preflight Preparation | 157 | 32 |
| II. Preflight Procedures | 75 | 16 |
| III. Takeoffs and Landings | 114 | 23 |
| IV. In-flight Maneuvers | 26 | 6 |
| V. Stall Prevention | 41 | 9 |
| VI. Instrument Procedures | 95 | 20 |
| VII. Emergency Operations | 74 | 15 |
| VIII. Postflight Procedures | 14 | 4 |

Before the test

- You must be at least 18 to take the ATM test.
- Authorization
- Bring a graduation certificate from an ATP Certification Training Program (ATP CTP).
- Registration

- Bring
- A current government-issued photo ID that shows your date of birth, signature, and physical residential address (a P.O. box doesn't count). Applicants under 18 without an acceptable ID need a parent or guardian to attest to their identity.
- Provided
- The test center provides the testing supplement, scratch paper, and a pen, and the test software has a built-in calculator. You may bring an E6B, plotter, or a basic or aviation calculator if you clear its memory in front of the proctor, though the center can refuse any personal calculator.
After the test

- You get your printed Airman Knowledge Test Report (AKTR) at the test center as soon as you finish. It shows your score and a code for each knowledge area you missed.
- Validity

- Higher score
- You can retake a passed test to improve your score after 30 days; the most recent score is the one that counts.
