Sportstar Flight Controls
4.4.5.1 Introduction
The Sportstar belongs to category of aerodynamically controlled airplanes
around three axes.
Aerodynamically controlled means, that the flight direction is changed due
to aerodynamic effect of air flow that circumfluents the control surfaces
which deflection is controlled with the airplane controls.
The three axes are the longitudinal axis, the lateral axis and the vertical
axis (see the picture on next page).
The Sportstar’s flight control system consists of primary and secondary
control system. The primary control system serves to safely control the
Sportstar during flight. It includes control of the ailerons, elevator and
rudder. Movement of any of these three primary flight control surfaces
changes the airflow and pressure distribution over and around the airfoil.
These changes affect the lift and drag produced by the airfoil/control
surface combination, and allow a pilot to control the Sportstar about its
three axes of rotation.
The secondary control system consists of the wing flaps control and
elevator trim tab control.
The picture on the next page shows the Sportstar control surfaces,
movement, axes of rotation, and type of stability.
