Flaps
Wing flaps are controlled by one central electric actuator connected to
the flaps by a lateral torque tube with transfer pushrods on each side
of the wing. The flap actuator is located in the centre channel of
fuselage between the seats and is controlled by programmable control
unit with three
positions switch (including “up”) located on the centre
console. An LCD indicator is integrated to the control unit for
confirmation of the positions (and transition - blinking). Wing flaps
deflection can be 0°, 10°, and 25°.
