An example method includes: determining a throttle command for a servomotor configured to control a position of a throttle lever, where the position of the throttle lever indicates a commanded thrust for the first engine of the aircraft; determining 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, where 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 changing the thrust generated by the first engine based on the modified trim command.
