Primary Flight Controls System
Architecture
L0Y06082 - L0DT0T0 - LM27DVLEVEL0201
The primary flight control system has four blocks:
- the CONTROL block with the pilot inputs (side sticks, rudder
pedals...),
- the COMPUTATION block with different computers as the PRIMary
systems, the SEcondary Computers, the electrical backup system, and
the Flight Control Data Concentrator (FCDC),
- the ACTUATION block with the flight control surfaces,
- and the INDICATING block with the monitoring displays (PFDs,
SD, and EWD).
Flight control computer reset P/BSWs are installed on the LH and RH
side flight control panels 1211VM and
1212VM installed on the cockpit overhead panel.
These reset P/BSWs are used for the software reset of the computers.

Secondary Flight Controls System
Architecture
The secondary flight control system has four blocks:
- the CONTROL with pilot layout (slat flap lever + RESET C/B),
- the COMPUTATION with two Slat Flap Control Computers
(SFCCs),
- the ACTUATION with the transmissions and surfaces,
- the INDICATING with the Primary Flight Display (PFD).
RESET C/Bs are installed on the 1231VM and 1222VM installed on
the cockpit overhead panel.
These RESET C/Bs are used for the software reset of the computers.
Computer Power Supply
L0Y06082 - L0DT0T0 - LM27DVLEVEL0201
The SFCC 1 is powered by 28VDC (DC ESS BUS).
The SFCC 2 is powered by 28VDC (DC BUS 2).

TRIMMABLE HORIZONTAL STABILIZER ACTUATOR BAY LIGHTS & POWER OUTLETS
DESCRIPTION (2)
System Overview
The Trimmable Horizontal Stabilizer (THS) bay has six Light Emitting
Diode (LED) type lights installed in the bay floor and bay ceiling. The
system also includes two 28 VDC power outlets to facilitate performance
of the maintenance tasks in this area. The lights are controlled from a
single toggle switch installed on the fuselage floor, on the LH of the bay
access door (311AB). The service lights and the power outlets are
energized from the 28 VDC GND SVCE BUS.
Human factor point:
L0Y06082 - L0DT0T0 - LM27DULEVEL0201
WARNING: BE CAREFUL WITH MOVING SURFACES,
MOVEMENT OF SURFACES CAN KILL OR CAUSE
INJURY TO PERSONS.
