INTRODUCTION
The primary flight controls for basic pitch, roll, and yaw control are mechanical, but in-
corporate electrical trim in all three axes. Secondary flight controls consist of electri-
cally controlled and hydraulically actuated spoilers/spoilerons and flaps.
The primary flight control surfaces consist of
ailerons on the outboard trailing edge of the
wings, which control the airplanes roll about
its longitudinal axis; a rudder on the vertical
stabilizer, which controls the airplanes yaw
about its vertical axis; and two elevators on the
trailing edge of the horizontal stabilizer, which
control the airplanes pitch about its lateral
axis. The primary flight controls are me-
chanically operated through dual control
columns, control wheels, and rudder pedals.
The ailerons incorporate mechanical balance
tabs to provide aerodynamic assistance. Trim
systems (pitch, roll and yaw) are electrically
operated and controlled. The left aileron and
the rudder feature trim tabs. The movable hor-
izontal stabilizer provides trim in the pitch
