Elevator
- see 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.
The stick shaker is fixed on the pitch lever linked to the pilot control column lever. This
is a mechanical device to vibrate the control wheel to warn the pilot in case of an
imminent stall.
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.
