How To Control An Aircraft

Plane Control Surfaces

  1. Primary Control Surfaces: A plane can be controlled in three differen axis.
    1. Ailerons – Roll Axis (Lingitudinal Axis)
    2. Elevators – Pitch Axis (Lateral Axis)
    3. Rudder – Yaw Axis (Vertical Axis)

A. Roll Axis (Lingitudinal Axis)(Yalpalama): The rolling motion is being caused by the rotation of the ailerons of the airplane. An aileron is a hinged flight control surface of the trailing edge of each wing of a fixed-wing aircraft. The ailerons are used in pairs to control the aircraft in roll axis.The ailerons work in opposition; when the right aileron increase then the left aileron decrease. This movement is called ‘rolling’ or banking’

B. Pitch Axis (Lateral Axis)(Yunuslama): The pitching motion is being caused by the rotation of the elevator of the airplane. The elevators are usually hinged to the tailplane or at the rear of the horizontal stabilizer. There is usually an elevator on each side of the vertical stabilizer. The elevators work together; they both increase or decrease together.

C. Yaw Axis (Vertical Axis)(Sapma): The yawing motion is being caused by the rotation of the rudder of an airplane. The rudder is a hinged section at the rear of the vertical stabilizer. The yaw axis is perpendicular to the wings and it is a side to side movement of the nose of the aircraft.


  1. Secondary Control Surfaces:    Flaps

    , Slats, Trims and Spoilers

Flaps:    Flaps are a type of high-lift device used to increase the lift of an aircraft wing at a given airspeed. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft.

Slats:     Slats are aerodynamic surfaces on the leading edge of the wings of fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack.

Trims:   Trims are small surfaces connected to the trailing edge of a larger control surface on an aircraft.

Spoiler: Spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil it, to reduce airspeed.
