Autothrottle/Autothrust
Definition
An automated system that adjusts engine power to maintain a selected airspeed, Mach number, or thrust setting. Autothrottle works with the autopilot to manage speed during all flight phases including approach.
Why Autothrottle/Autothrust Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Autothrottle/Autothrust works helps you interpret cockpit information correctly and recognize instrument failures before they become emergencies. This knowledge is especially critical for instrument-rated pilots flying in reduced visibility.
Exam Tip
This concept is commonly tested in instruments-related questions on FAA and EASA exams. Make sure you can explain Autothrottle/Autothrust in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
