About the ATM exam
The Airline Transport Pilot Multiengine (ATM) knowledge test covers what an airline captain must know: regulations, weather, high-altitude aerodynamics, air carrier operations, human factors, transport-category systems and performance, instrument procedures and engine-out operations.
The test follows the knowledge tasks of the ATP ACS (FAA-S-ACS-11A). Applicants must complete the ATP Certification Training Program (ATP CTP) before taking it. The FAA does not publish per-area percentages, so our domain weights are an estimate.
