• Non lights out switch position - White light. If normally the system should
be operating and is deactivated a white OFF light is illuminated. If normally
the system should not be operating and is activated a white ON light is
illuminated.

There are some switches on the overhead panel which are used on a
temporary basis or may have an indication of their state. The logic is;
• Temporary selection for operational reasons - Blue ON light e.g. anti-ice
• Applicable system status - Green light - e.g. APU available.
You will see this philosophy demonstrated throughout the course.

Below the ECAM displays, on the center
pedestal, is the ECAM control panel. The two
controls on the left hand side are to adjust the
brightness of the two ECAM screens or to turn
them off. We will look at the rest of the
controls on this panel in more detail later.

Just below the ECAM screens, on the pedestal, is a switching panel for
use in abnormal situations to restore data to the EFIS and ECAM displays.
You will use this panel in the EIS Reconfiguration module.

In front of each pilot there are two attention
getters, a red MASTER WARNING, and an
amber MASTER CAUTION. As a further means
of getting the pilots attention, there is a
loudspeaker on each side of the cockpit for
aural alerts and voice messages.
Note; The loudspeakers can also be used to
listen to ATC and the intercom.

Now, let’s go back to the EFIS system.
For the EFIS displays, data from the Air
Data and Inertial Reference System
(ADIRS) plus Navigation data from the
Flight Management and Guidance System
(FMGS) is fed directly to three Display
Management Computers (DMC).

The three identical DMC process the data
and generate the images to be displayed.
Under Normal circumstances:
• DMC1 supplies EFIS information to the
Captains’ PFD and ND
• DMC2 supplies the First Officers’ PFD
and ND.
• DMC3 is available as a backup.
You will see the use of DMC3 in the
abnormal operation module.

Now, let’s look at the other EIS sub-system,
ECAM, and how the ECAM displays get their
data.
Sensors are fitted throughout the aircraft to
monitor the various systems, including system
controls operated in the flight deck.

DMC 3
Data for certain
parameters, for example
Fuel Quantity and
Primary Engine
Indications, is routed
directly from the system
sensors to the three
DMC.
Note that there are
separate channels within
each DMC for ECAM and
EFIS.

For the majority of the systems the sensors
supply data to 2 System Data Acquisition
Concentrators (SDAC). The SDAC acquire
system data, process it, and send System page
data to the 3 DMC.
