ELECTRONIC INSTRUMENT MENU ECAM System 1/117
ELECTRONIC INSTRUMENT MENU
ECAM System 2/117
The ECAM system keeps a
watchful eye on all of the aircraft
systems monitoring them for any
abnormal states.
ELECTRONIC INSTRUMENT MENU
ECAM System 3/117
If something abnormal is
detected ECAM will alert the pilots
and provide an electronic checklist
to help handle the abnormality.
ELECTRONIC INSTRUMENT MENU
ECAM System 4/117
The two ECAM displays, the E/WD
and the SD, are where the ECAM
system provides normal and abnormal
system information to the pilots.

Color coding is used on the ECAM
screens for clarity and to aid identification
of abnormal parameters. The main colors
used are:
• White,
• Blue,
• Green,
• Amber,
• Red.
During the course, you will become
familiar with the use of this color coding.
Let’s start with the last 3, Green, Amber,
and Red, which are the most important.
ELECTRONIC INSTRUMENT MENU
ECAM System 6/117
Green color coding is used to
indicate a normal condition. Notice
that on the E/WD and the SD shown,
all indications are normal.
= NORMAL
ELECTRONIC INSTRUMENT MENU
ECAM System 7/117
= ABNORMAL
Amber color coding is reserved for
abnormal indications that require
crew awareness, but not immediate
crew action.
Notice on the E/WD, the amber
failure message and on the SD the
amber indications.
AWARENESS
NOT IMMEDIATE ACTION
ELECTRONIC INSTRUMENT MENU
ECAM System 8/117
Red color coding is reserved for
serious parameter exceedance and
warnings that require immediate crew
action.
Notice on the E/WD, the red
parameter indication and the red
warning message.
Let’s now look at the two ECAM
displays in a little more detail.
= WARNING
IMMEDIATE CREW ACTION
ELECTRONIC INSTRUMENT MENU
ECAM System 9/117
The E/WD is divided into two main
parts. The upper area is used for the
main engine parameters, Fuel on
Board, and Slat/Flap position. These
indications will be discussed in the
appropriate system modules.
ELECTRONIC INSTRUMENT MENU
ECAM System 10/117
Under normal conditions, the lower part of the E/WD
is used to display MEMO. In the example shown the
memos indicate that the seat belt and no smoking
signs are switched on and that the APU is available for
use.
MMeemmooMMeessssaaggeess
ELECTRONIC INSTRUMENT MENU
ECAM System 11/117
If failures occur Warning/Caution messages are
displayed in place of the memos. In the example shown
there is an amber caution message with a series of blue
action items. These action items are your electronic
checklist to respond to the particular abnormal
situation
WWaarrnniinnggss//CCaauuttiioonnMMeessssaaggeess
ELECTRONIC INSTRUMENT MENU
ECAM System 12/117
The SD is used to display particular system information. In the example
shown the CRUISE page is displayed. This is the page normally seen for the
majority of the time that the aircraft is airborne. Information, that is useful
during flight, from several systems is displayed.
The individual indications will be covered in the appropriate system
modules.

ELECTRONIC INSTRUMENT MENU
ECAM System 13/117
The SD can also be used to display synoptic diagrams of
the aircraft systems, System pages. In the example shown
the hydraulics system page has been called.
You will see later how these system pages are called
either manually or automatically.
ELECTRONIC INSTRUMENT MENU
ECAM System 14/117
An aircraft STATUS page may be displayed on the SD to check the
state of the aircraft. A NORMAL message is displayed to indicate that the
aircraft state is normal and that there are no inoperative systems.
Let’s see what the STATUS page looks like when things are not normal,
for example, following a system failure.

Individual airlines can choose which units they wish to use for
certain parameters on the ECAM screens. In the examples shown we
have highlighted the areas on the screens where the units used differ.
UUSSUUNNIITTSS MMEETTRRIICCUUNNIITTSS
ELECTRONIC INSTRUMENT MENU
ECAM System 21/117
Because these indications are only mentioned in a few areas of the
ground school course, we will use boxes to indicate that the units may
differ depending on your airlines’ choice. The boxes mean that the
information in this area of the screen is irrelevant to the system being
studied. When a system, for example Fuel, is being studied then
appropriate unit values will be shown.

ECAM System 22/117
Under normal conditions the
ECAM system provides the pilots
with the information that they “Need
to Know” for the particular phase of
flight, no more no less.
As an example during the
approach when the landing gear is
extended the ECAM WHEEL system
page is automatically displayed.
ELECTRONIC INSTRUMENT MENU
ECAM System 23/117
The ECAM system divides the various stages of a flight
into phases, from initial electrical power up until after
engine shutdown.
The ECAM system will avoid alerting the pilots
unnecessarily during the critical flight phases of take off and
landing. The warnings and cautions that can be delayed
until a less critical phase of flight will be inhibited.

ECAM System 24/117
We will now look at the different
ways that the ECAM system advises
you when things are not going
exactly right. We will start with a
minor advice indication and work up
to a major fault, concentrating on the
two ECAM screens.
ELECTRONIC INSTRUMENT MENU
ECAM System 25/117
If a system parameter, for example an
engine vibration level, approaches a limit
the ECAM system will advise you of this
by displaying the relevant system page on
the SD. The affected parameter will pulse.
Notice that at this stage, the parameter is
still shown in green since it is still within
normal limits.
This is known as an ECAM ADVISORY.
Now let’s look at what happens when
ECAM detects a minor system failure.
ELECTRONIC INSTRUMENT MENU
ECAM System 26/117
When a failure occurs leading to a
loss of redundancy or loss of a
system that does not affect the safety
of the flight, for example DFDR
FAULT, the ECAM system will inform
you by displaying an amber
CAUTION message on the E/WD.
At the same time the two CLEAR
keys on the ECAM control panel will
illuminate.
ELECTRONIC INSTRUMENT MENU
ECAM System 27/117
The first action is to ensure that
the aircraft is on a safe flight path.
This fault only requires crew
awareness so if required the
handling of the fault can be delayed.
ELECTRONIC INSTRUMENT MENU
ECAM System 28/117
Normally the PNF carries out the
ECAM procedure while the PF is
responsible for the aircraft flight
path. For this exercise you are the
PNF.
Read the title of the failure, in this
case “RECORDER DFDR FAULT”.
The PF will ask you to perform
ECAM actions.
ELECTRONIC INSTRUMENT MENU
ECAM System 29/117
In this case there are no actions
required so, after confirmation from
the PF, the caution message can be
cleared by pressing one of the
CLEAR keys on the ECAM Control
Panel.
Press a CLEAR key
ELECTRONIC INSTRUMENT MENU
ECAM System 30/117
As a result of pressing either
CLEAR key the Caution message has
been cleared from the E/WD and the
STATUS page is displayed
automatically.
In this example you can see that
the inoperative system is the DFDR.
ELECTRONIC INSTRUMENT MENU
ECAM System 31/117
On the ECAM control panel the
STATUS key is illuminated along with
the two CLEAR keys.
When safe to do so the STATUS
page is reviewed by both pilots. After
confirmation from the PF the
STATUS page is cleared by pressing
either the STS key or one of the CLR
keys.
Clear the STATUS page
ELECTRONIC INSTRUMENT MENU
ECAM System 32/117
Notice that:
• on the E/WD there is a boxed STS
caption to tell you that there is
information on the STATUS page,
• on the ECAM control panel there
are no lights.
The ECAM actions for the DFDR
fault are complete.
ELECTRONIC INSTRUMENT MENU
ECAM System 33/117
We will now look at what happens
when a slightly more serious fault is
detected by ECAM. The fault that we
will use is an overheat of the Blue
Hydraulic system reservoir. We will
concentrate on the use of the ECAM
system, how it alerts you, and how it
helps you to deal with the fault. The
hydraulic indications themselves will
be covered in the appropriate
modules.
Click on the forward arrow to
initiate the failure.
ELECTRONIC INSTRUMENT MENU
ECAM System 34/117
When the fault occurs the ECAM system
alerts the crew aurally and visually. You will
hear a single chime and see the MASTER
CAUTION lights. To cancel the MASTER
CAUTION lights, and reset the alerting system,
one of the MASTER CAUTION pb must be
pressed.
Extinguish the Master Caution light
ELECTRONIC INSTRUMENT MENU
ECAM System 35/117
The MASTER CAUTION is extinguished and
the alerting system is reset.
ELECTRONIC INSTRUMENT MENU
ECAM System 36/117
The first priority is always to ensure the safe
flight path of the aircraft before dealing with the
fault. The MASTER CAUTION means that the
abnormal situation needs crew awareness but
not immediate action.
= ABNORMAL
AWARENESS
NOT IMMEDIATE ACTION
ELECTRONIC INSTRUMENT MENU
ECAM System 37/117
The indications are:
• A failure message on the E/WD,
• The system synoptic associated
with the fault is automatically
displayed on the SD,
• The Clear keys on the ECAM
control panel light up.
ELECTRONIC INSTRUMENT MENU
ECAM System 38/117
Let’s study the details on the
E/WD first. The system title is
underlined, in this case HYDraulics,
and the fault is shown alongside,
Blue ReSerVoiR OVerHeaT. Notice
that abbreviations are used.
ELECTRONIC INSTRUMENT MENU
ECAM System 39/117
If you look carefully at the
Hydraulic system display you will
notice an amber OVHT message is
displayed. This abnormal indication
is how the fault is shown on the
system synoptic.
ELECTRONIC INSTRUMENT MENU
ECAM System 40/117
The PF will ask you to perform the
ECAM actions. In this example there
is a blue action line on the E/WD
telling you to switch off the Blue
Electrical Pump.
Let’s check the overhead panel.
ELECTRONIC INSTRUMENT MENU
ECAM System 41/117
On the overhead panel an amber
fault light has illuminated on the
Hydraulic control panel.
ELECTRONIC INSTRUMENT MENU
ECAM System 42/117
The fault light on the HYD panel
helps you to locate the switch to be
operated. We will carry out the action
for you.
ELECTRONIC INSTRUMENT MENU ECAM System 43/117
ELECTRONIC INSTRUMENT MENU
ECAM System 44/117
When the pump is switched off the
action line is removed. The Blue
hydraulic system depressurizes, as
shown on the HYD page by the
amber indications. The ECAM
system detects the drop in pressure
and generates a further alert.
ELECTRONIC INSTRUMENT MENU
ECAM System 45/117
You hear the chime and see the Master
Caution lights.
Extinguish the Master Caution lights
ELECTRONIC INSTRUMENT MENU ECAM System 46/117
ELECTRONIC INSTRUMENT MENU
ECAM System 47/117
There is now a new abnormal
message on the E/WD , B SYS LO PR.
The message is boxed to indicate
that the loss of the blue hydraulic
system is classed as a Primary
failure that will affect other systems.
ELECTRONIC INSTRUMENT MENU
ECAM System 48/117
The systems affected are shown
on the right of the E/WD as starred
items called Secondary failures.
In this example the Primary failure
of the Blue hydraulic system has
caused a Secondary failure of Flight
Controls.
ELECTRONIC INSTRUMENT MENU
ECAM System 49/117
After review and confirmation from
the PF the Hydraulic failure message
on the E/WD can be cleared.
Clear the HYDRAULICS message.
ELECTRONIC INSTRUMENT MENU
ECAM System 50/117
Notice that normal memos have
returned on the left side of the E/WD.
The ECAM F/CTL system page is
displayed on the SD which
corresponds to the secondary failure
item on the E/WD .
ELECTRONIC INSTRUMENT MENU
ECAM System 51/117
On the ECAM F/CTL page, notice
that the controls affected by the loss
of Blue hydraulics have amber
indications. These indications will be
discussed in the Hydraulic and Flight
Control modules.
ELECTRONIC INSTRUMENT MENU
ECAM System 52/117
After review and confirmation from
the PF the Flight Control secondary
failure message can be cleared.
Clear F/CTL
ELECTRONIC INSTRUMENT MENU
ECAM System 53/117
Notice that the secondary failure
indication on the E/WD is removed.
The STATUS page is now
displayed containing several pieces
of information.
The first area gives procedures to
be applied for approach, Landing
distance factors, and other
information. You will study the
procedures in the appropriate system
lessons.
ELECTRONIC INSTRUMENT MENU
ECAM System 54/117
In this example the inoperative
systems are:
• CAT 3, which means that Category
3 autoland is not available,
• BLUE HYD, the system was
switched off during the ECAM
procedure,
• SPLR 3, the spoilers that are
inoperative because there is no blue
hydraulic pressure.
ELECTRONIC INSTRUMENT MENU
ECAM System 55/117
The STATUS page is reviewed by
both pilots. After confirmation from
the PF the STATUS page can be
cleared.
Clear the STATUS page
ELECTRONIC INSTRUMENT MENU
ECAM System 56/117
The ECAM actions for a Blue
Hydraulic Reservoir Overheat are
complete. Notice that the STATUS
reminder is displayed at the bottom
of the E/WD reminding you that there
is information on the STATUS page.
This is important since there were
approach procedures to be applied.
ELECTRONIC INSTRUMENT MENU
ECAM System 57/117
If it contains information, the
ECAM system automatically recalls
the STATUS page during the
approach phase when the slats are
extended. This is done so that if
there are any items affecting the
approach and landing they will be
presented to you at an early stage.
You can see that in the example
shown there are approach
procedures. You will see how these
approach procedures are applied
later in the course.
Clear the STATUS page.
ELECTRONIC INSTRUMENT MENU
ECAM System 58/117
The STATUS page is cleared and
the CRUISE page is displayed.
ELECTRONIC INSTRUMENT MENU
ECAM System 59/117
So far we have looked at how the ECAM system advises you of minor failures.
We will now look at what happens when there is a serious failure that requires
immediate action. To demonstrate this we will use an Engine Fire. As before we
will not concentrate on the system failure but on ECAM indications and
procedures.
Be ready to cancel the warning by pressing a MASTER WARNING pb.
Click on the forward arrow to initiate the failure.

ELECTRONIC INSTRUMENT MENU ECAM System 60/117
ELECTRONIC INSTRUMENT MENU
ECAM System 61/117
When the fault occurs the ECAM system
alerts the crew aurally and visually. You hear a
continuous repetitive chime and see the
MASTER WARNING lights flashing. Press one
of the the MASTER WARNING pb to:
• cancel the MASTER WARNING lights,
• stop the chimes,
• reset the alerting system.
ELECTRONIC INSTRUMENT MENU
ECAM System 62/117
On the E/WD the red message
ENG 1 FIRE and the associated
procedure are displayed.
The red indications on the FIRE
panel and the ENG panel provide
confirmation and identification of
the affected engine.
The ENGINE page has
automatically been called on the
SD, and in this example the nacelle
temperature is pulsing.
ELECTRONIC INSTRUMENT MENU
ECAM System 63/117
Notice that there is a red LAND
ASAP message on the E/WD. This
means that ECAM has determined
that the fault detected is serious
enough to require a landing as
soon as possible.
ELECTRONIC INSTRUMENT MENU
ECAM System 64/117
The PF maintains control of the
aircraft and asks you, as PNF, to
start the procedure. We will do the
ECAM actions for you starting with
setting thrust lever 1 to idle.

ELECTRONIC INSTRUMENT MENU ECAM System 71/117
ELECTRONIC INSTRUMENT MENU ECAM System 72/117
ELECTRONIC INSTRUMENT MENU
ECAM System 73/117
After switching ENG 1 off, the
after ENG 1 SHUT DOWN
procedure is shown on the E/WD.
Notice that the amber caution
message has appeared below the
red warning. This happens because
you have to finish the engine fire
procedure before carrying out the
actions for ENG 1 SHUTDOWN. The
ECAM system has automatically
allocated priority to the warning.
ELECTRONIC INSTRUMENT MENU
ECAM System 74/117
As a result of switching off the
engine there are now secondary
failures.
ELECTRONIC INSTRUMENT MENU
ECAM System 75/117
The next ECAM action is to push
the engine 1 fire pb. We will do
this for you.

The next action line is to notify
ATC.
Since the ECAM system can not
tell when you are talking there is no
feedback so this line will not
disappear.
ELECTRONIC INSTRUMENT MENU
ECAM System 93/117
Notice that we still have a red fire
indication which means that the fire
is not extinguished. Another
condition line has appeared and a
second countdown automatically
starts. This one is 30 seconds long.
We have paused the countdown.

Agent 1 managed to extinguish the
fire. The countdown for agent 2
stopped immediately.
Notice that:
• the ENG FIRE procedure on the
ECAM disappeared. This means the
fire is out,
• the local warnings on the FIRE
panel and the ENG panel are no
longer illuminated, confirming that
the fire is out,
• LAND ASAP has changed from
red to amber which means that ECAM
has determined that the fault is less
critical, but still requires a landing as
soon as possible.
ELECTRONIC INSTRUMENT MENU
ECAM System 99/117
The remaining steps are similar to
those seen for an ECAM CAUTION
so we will stop here.
You have seen that the ECAM
system has provided a smart and
interactive checklist to help you deal
with a major problem.
ELECTRONIC INSTRUMENT MENU
ECAM System 100/117
So far the messages and
procedures displayed on the E/WD
have not been more than 7 lines, so
we have had room to display them
all. Let’s look at how ECAM copes
with a long procedure.
ELECTRONIC INSTRUMENT MENU
ECAM System 101/117
In this example of the indications for
an engine fire on the ground there is an
overflow arrow to indicate that there is
more information to be seen.
For training purposes we have shown
the rest of the procedure below the
E/WD. We will complete the ECAM
actions and you will see the associated
line of the procedure disappear.

ELECTRONIC INSTRUMENT MENU
ECAM System 111/117
To summarize; initially you see all the
information on the left side of the
STATUS page, and then all the
inoperative systems on the right.
ELECTRONIC INSTRUMENT MENU
ECAM System 112/117
To complete this module let’s briefly
look at ECAM priority. We will only use
the bottom part of the E/WD for this
demonstration.
You are part way through the ENG 1
FIRE procedure when ECAM detects
another failure.
ELECTRONIC INSTRUMENT MENU
ECAM System 113/117
The low priority RECORDER DFDR
FAULT has appeared below the higher
priority ENG 1 FIRE and ENG 1
SHUTDOWN procedures.
Unfortunately it is one of those days
and another failure occurs.
ELECTRONIC INSTRUMENT MENU
ECAM System 114/117
The AP OFF warning has appeared
above the ENG 1 FIRE procedure. ECAM
has automatically assigned priority to
the AP OFF message because the first
priority is always to fly the aircraft!
ELECTRONIC INSTRUMENT MENU
ECAM System 115/117
The low priority RECORDER DFDR
fault is now off the screen. You are
advised that the fault is there by the unstarred
RECORDER text in the right
hand column of the E/WD and the green
overflow arrow.
We will clear the AUTO FLT AP OFF
warning for you.
ELECTRONIC INSTRUMENT MENU
ECAM System 116/117
The RECORDER DFDR FAULT
message is back at the bottom of the
E/WD and the RECORDER text has been
