Definition
An onboard computer in a transport-category aircraft that automatically calculates and commands the appropriate engine thrust setting for each phase of flight. It works with the autothrottle and flight management system to set thrust limits for takeoff, climb, cruise, go-around, and other phases, taking into account air temperature, altitude, aircraft weight, and engine condition.
Plain English
A computer that figures out how much engine power the aircraft should be using right now and tells the throttles to deliver it. It handles the math and adjustments so the crew doesn't have to set thrust by hand for every phase of flight.
Context Anchor
A pilot may encounter this term in turbine-aircraft operating manuals, engine-power setup procedures, and automatic thrust system descriptions.
Derivation
Thrust is the forward force produced by the engines. 'Management' here means controlled allocation -- deciding how much thrust to use and when. The computer manages thrust the way a pilot would: setting limits, protecting the engines, and matching power to the phase of flight.
Why Pilots Care
It reduces pilot workload while keeping engine thrust within safe and efficient limits for each phase of flight.
Intuition Check
Do not read “management” as simple monitoring. A Thrust Management Computer does more than display engine power; it calculates the target thrust and may help command or maintain it.
Example Sentence 1
After takeoff, the thrust management computer automatically reduced power to the climb thrust setting.
Example Sentence 2
During the descent the thrust management computer reduced engine thrust to maintain the planned speed profile.
