Roll Control
The roll control surfaces consist of hydraulically powered ailerons
and flight spoilers, which are controlled by rotating either control
wheel.

Pitch Control
The pitch control surfaces consist of hydraulically powered
elevators and an electrically powered stabilizer. The elevators
are controlled by forward or aft movement of the control column.
The stabilizer is controlled by autopilot trim or manual trim.

Yaw Control
Yaw control is accomplished by a hydraulically powered rudder
and a digital yaw damper system. The rudder is controlled by
displacing the rudder pedals. The yaw damping functions are
controlled through the stall management/yaw damper (SMYD)
computers.

Primary Flight Controls
Flaps and Slats
The flaps and slats are high lift devices that increase wing lift and decrease stall speed during takeoff,
low speed maneuvering and landing. LE devices consist of four flaps and eight slats: two flaps inboard
and four slats outboard of each engine. Slats extend to form a sealed or slotted leading edge
depending on the TE flap setting. The TE devices consist of double slotted flaps inboard and outboard
of each engine. TE flap positions 1–15 provide increased lift; positions 15–40 provide increased lift and
drag. Flaps 15, 30 and 40 are normal landing flap positions.

Speed Brakes
The speed brakes consist of flight spoilers and ground
spoilers. Hydraulic system A powers all four ground
spoilers, two on the upper surface of each wing. The
SPEED BRAKE lever controls the spoilers. When the
SPEED BRAKE lever is actuated all the spoilers extend
when the airplane is on the ground and only the flight
spoilers extend when the airplane is in the air.
