The flight controls keep the airplane at the necessary attitude
during flight. They have movable surfaces on the wing and the
empennage. These are the two types of flight control systems:
* Primary
* Secondary.
Primary Flight Control System

three axes: lateral, longitudinal, and vertical. The primary flight
control system has these components:
* Aileron (2)
* Elevator (2)
* Rudder.
Secondary Flight Controls
The secondary flight controls improve the lift and handling
properties of the airplane. The secondary flight control system
has these components:
* Leading edge
devices (12)
