Engineering Review
(1) Ailerons: provide primary lateral control
and lateral trim
(2) Aileron actuators: provide mechanical
power to move aileron control surfaces
(3) Aileron trim actuator: provides power to
trim aileron control surfaces
(4) Aileron spring feel unit: compensates
for aerodynamic forces acting on control
surfaces and provide artificial feel for the
pilot
