PILOT'S OPERATING HANDBOOK
DESCRIPTION

WINGS

The wings are monocoque, bi-spar structures. Main spars of each wing are linked to the fuselage by two integral
attach fittings. Each wing contains a main landing gear well and sealed casings forming the fuel tank. The wing
leading edge is equipped with a deicing system.
Each wing extremity is equipped with a winglet.

AILERONS, SPOILERS AND PITCH TRIM TAB

The ailerons located on external trailing edge of each wing are hinged on two attach fittings fixed on the rear spar.
They allow airplane lateral control and are controlled mechanically through control wheel rotation.
The spoilers located in front of flaps, on top skin side, are mechanically linked to the ailerons.
Trim tab attached on the trailing edge of L.H. aileron is electrically activated by a trim knob, through an actuator.

WING FLAPS

(Figure 7.2.2)
The wing flaps are large span slotted flaps with a single rotation point. They are activated by actuating
rod-controlled screw jacks linked to an electric motor located under the floor, inside the fuselage.
A preselection control located on the right side of pedestal console allows the pilot to select one of the three
positions (UP - TO - LDG). For each control position, a deflection angle is defined (0°, 10°, 34°).
A monitoring device interrupts flaps movement as soon as a deflection dissymmetry is detected.

EMPENNAGES

Empennages are composite structures. The horizontal empennage consists of a horizontal stabilizer (PHF),
control surfaces and elevator trim tabs ; the vertical empennage consists of a vertical stabilizer, the rudder and the
rudder trim tab. The empennage leading edge is equipped with a deicing system.
