Yes and No. This is from the E-170 aircraft manual. I love this CBT training, no big manuals to lug around, although they gave them to us.

[/font]The Flight Control System is comprised of the primary and the secondary flight control systems and their associated system components. The primary flight control system consists of:
•Ailerons and the multi-function spoilers for roll axis control
•Elevators for pitch axis control
•Rudder for yaw axis control
The secondary flight control system consist of:
•Horizontal stabilizer •Flaps and Slats •The multi-function spoiler (when used as speed brakes or ground spoilers) •Dedicated ground spoilers Hydraulic actuators control the respective flight control surfaces. These are generally referred to as Power Control Units (PCUs).
The ailerons are driven by conventional control cables that run from each control wheel back to a pair of hydro-mechanical actuators.
Elevators, rudders and roll spoilers as well as all secondary flight control systems, including the horizontal stabilizer, flaps and slats, ground spoilers and speed brakes, are controlled electronically using Fly-by-Wire (FBW) technology. The primary flight control electronics are generally comprised of two complementary parts: •The Primary Actuator Control Electronics (P-ACE) •The Flight Control Module (FCM) Primary Actuator Control Electronics (P-ACE) and/or Flight Control Modules (FCM) are employed to operate the respective electrohydraulic or electro-mechanical actuators.
