DESCRIPTION

7.4 - FLIGHT CONTROLS

Flight controls consist of roll, pitch and rudder controls, as well as roll trim tab, pitch trim tab and rudder trim tab
controls.
NOTE : During airplane parking, it is recommended to lock flight controls (see Figure 8.6.2)

ROLL

(Figure 7.4.1)
The roll control is activated by an assembly of rods and cables which links control wheels with the ailerons and the
spoilers.
Aileron displacement is combined with that of spoilers, located at upper surface of each wing forward of flaps.
The spoiler rises from wing upper surface profile, when the aileron is deflected upwards and remains in wing
profile, when the aileron is deflected downwards.
Control wheel movement is transmitted through rods to fuselage roll lever located under the floor. The movement
is then transmitted through cables to the spoiler mechanism and from the spoiler mechanism to wing roll lever
which activates the aileron through a rod.
A rudder / roll combination spring-type system induces roll deflection at the time of pedals movement and vice
versa.

ROLL TRIM

(Figure 7.4.2)
The roll trim is controlled by a trim tab attached at trailing edge of the L.H. aileron. The trim tab is connected through
two links to an electric actuator located in the aileron. A trim switch located on pedestal controls the roll trim tab
maneuver.
Roll trim tab electrical circuit is protected by the "AIL TRIM" circuit breaker.
