Which flight computer controls inboard flight spoilers?

The correct response relates to the functionality of the SECU (Spoiler Efficiency Control Unit) systems, particularly SECU 1, which is responsible for managing the inboard flight spoilers. These spoilers play a crucial role in controlling the aircraft's lift and drag during flight operations.

SECU 1 specifically monitors and regulates the deployment of the inboard flight spoilers, assisting in maintaining optimal flight conditions. By controlling the effectiveness of these spoilers, SECU 1 ensures that the aircraft can efficiently manage its pitch and roll, especially during maneuvers such as descent or approach. This is vital for both performance and safety, as accurate spoiler deployment allows for controlled deceleration and better responsiveness to pilot inputs.

In contrast, the other SECU units—SECU 2, SECU 3, and SECU 4—are designated for controlling different systems of the aircraft, which is why they do not relate to the inboard flight spoilers. Each unit has specific responsibilities, and the distinction among them is important for understanding the overall functioning of the aircraft's flight control systems.
