3.2.2 Trim
The Eclipse 500 has four trim motors; two are used for pitch trim, one for roll (aileron)
trim and one for yaw (rudder trim). Pilot control for pitch and roll trim is through the
trim switch on each sidestick, while rudder trim inputs are made through the rudder
trim switch on the throttle quadrant.
The ACS commands the actuators based on these pilot inputs. The left ACS is
responsible for commanding and monitoring the left pitch trim and roll trim motors,
while the right ACS is responsible for commanding and monitoring the right pitch trim
and yaw trim motors.
In addition to commanding the trim motors the ACS also receives position information
from each actuator and monitors for unexpected movement, actuator position errors,
as well as pitch trim disagreement.
