Low throttle rate command compensation via full authority engine trim

A non-transitory computer readable medium having stored therein instructions that, in response to execution by a thrust management computer of an aircraft having at least a first engine and a second engine, cause the thrust management computer to perform operations comprising:

• determining a throttle command for a servomotor configured to control a position of a throttle lever, wherein the position of the throttle lever indicates a commanded thrust for the first engine of the aircraft;
• determining, based on detecting a difference between a thrust generated by the first engine and a respective thrust generated by the second engine, a trim command for the first engine to equalize the thrust of the first engine with the respective thrust of the second engine;
• determining that a magnitude of the throttle command is less than a magnitude of a threshold throttle command indicative of a dead zone of the servomotor, wherein the servomotor is irresponsive to a given throttle command within the dead zone;
• modifying the trim command based on the throttle command to generate a modified trim command that compensates for irresponsiveness of the servomotor to the throttle command;
• and
• providing the modified trim command to an electronic engine controller of the first engine, thereby changing the thrust generated by the first engine.

A thrust management computer of an aircraft having at least a first engine and a second engine, the thrust management computer comprising:

• one or more processors;
• and
• data storage storing thereon instructions, that when executed by the one or more processors, cause the thrust management computer to perform operations comprising:
• determining a throttle command for a servomotor configured to control a position of a throttle lever, wherein the position of the throttle lever indicates a commanded thrust for the first engine of the aircraft;
• determining, based on detecting a difference between a thrust generated by the first engine and a respective thrust generated by the second engine, a trim command for the first engine to equalize the thrust of the first engine with the respective thrust of the second engine;
