Which component commands the roll spoilers to move in an aircraft?

The Spoiler Electronic Control Unit (SECU) computer is responsible for commanding the roll spoilers to move in an aircraft. This specialized unit processes inputs from various flight control systems and pilot commands, translating them into appropriate signals that actuate the roll spoilers.

These roll spoilers play a crucial role in managing the aircraft's roll during flight, particularly during maneuvers requiring lateral directional control. The SECU uses data from sensors and other control systems to ensure that the spoilers function correctly and efficiently, optimizing the aircraft's performance.

In contrast, while the Flight Control Computer integrates multiple systems for overall flight control, it does not directly command the movement of specific control surfaces like the roll spoilers. The Aircraft Systems Management Unit oversees broader system functionality but does not focus solely on spoiler operation. The Hydraulic Control Panel, while essential for the hydraulic systems that might support the actuation of control surfaces, does not directly control or command the movement of the roll spoilers themselves.
