ELEVATOR
(Figure 7.4.3)
Both elevators are activated simultaneously by the same control. Each
control surface is hinged at three points to the rear part of horizontal stabilizer.
The control wheel controls the two elevators through rods, bearings and
bellcranks.
A spring actuator creates a ”nose--down” artificial force which allows a better
static stability.
Each control surface is provided with an automatic anti--tab (automaticity
about 0.3), which is also used as trim tab.
PITCH TRIM
(Figure 7.4.4)
The pitch trim is accomplished through the two anti--tabs located on left and
right elevators.
The trim tab can be controlled electrically or manually. It is activated through
cables and a chain on two screw jacks attached to the horizontal empennage.
The electrical control consists of a switch located on the pilot control wheel
and a servo--motor attached under the pedestal.
The electrical circuit for pitch trims is protected by the ”AP SERVOS” circuit
breaker.
Manual control wheel is installed vertically on left side of pedestal console.
