1. GENERAL
The flight controls are divided into two groups:
− Primary flight controls consisting of elevators,
ailerons and rudder.
− Secondary flight controls consisting of trim sys-
tem and the flaps.
All primary flight controls are conventional, manually
operated rod and cable assemblies. All control sur-
faces are mass balanced.
The flaps are electrically controlled and hydraulical-
ly actuated.
The trim system is electrically controlled and electri-
cally actuated.
Geared tabs are used with the elevator and aileron
systems while a spring tab is used with the rudder
system.
The geared tabs deflect proportionally to control
surface movement to assist the control forces by
means of aerodynamic effect on the tab.
The rudder pedals are mechanically linked to the
spring tab, and via torsion bars to the rudder.
A rudder travel limiting system limits the control
system operating range as a function of airspeed.
All tabs are controlled electrically from cockpit when
used for trimming.
On ground, all primary flight controls can be locked
by a gust lock system.
