GENERAL
The primary flight control system consists of elevators, ailerons and
rudder. Elevators are mechanically actuated. The ailerons and rudder
are hydraulically powered and may also be mechanically actuated in
case of loss of both hydraulic systems.
Trim system is provided in all axis. Tabs are provided for pitch control
only, and are not available for ailerons and rudder.
A gust lock system blocks elevator controls on the ground, avoiding
damage to the control systems in case of strong wind gusts. The
rudder and ailerons are hydraulically damped for the same purpose.
An electrically operated flap system is provided with five discrete
positions.
Speed brakes installed overwing allow increased descent rate and help
in decelerating the airplane. Ground spoilers destroy lift, thus providing
better braking effectiveness.
