The engine page is automatically displayed
during engine start sequence. It can be
displayed at any time by pressing the ENG key
on the ECAM control panel.
During the cruise, the CRUISE page is
automatically displayed on the SD. It shows
important information about the engines and
the cabin pressurization and temperature, as
shown on the ENG and PRESS pages :
1. Fuel Used by each engine, as shown on the
engine page
2. Oil quantity (in quarts), as shown on the
engine page
3. Vibrations
4.5.6. Cabin DeltaP, vertical speed and altitude,
as shown on the PRESS page
7. Cabin temperature, as shown on the COND
page.

Engine Start & Stop on Ground
When the aircraft is parked on the ground and
engines have to be started, the APU must be
started first in order to provide air bleed
necessary for the engine start sequence. Refer
to the APU section for more information about
APU start and APU bleed.
When the APU is started and APU bleed is on,
the engine start is managed through the ENG
section located on the pedestal, just below the
thrust levers :
1.2.Engine Master Switch for engine 1 and 2
3. Engine mode switch.
To start the engine, the engine mode switch
must be placed on the IGN/START position.
This operation turns on the engine igniters
and the FADEC (the E/WD engine information
become active). This switch position can also
be used when the engines are running in case
of heavy rain. It provides continuous ignition,
and it reduces the risk of having an engine
stop.
The engine master switches can then be used
to initiate the engine start sequence. The crew
just has to move each engine master switch up
and the FADEC does the rest to start the
corresponding engine. On the twin-engine
aircrafts, both engines can not be started
simultaneously because the APU does not
provide enough air for 2 engines. Usually,
engine 2 is started first. This is because it
provides hydraulic pressure to the Yellow
circuit, the one used by the brakes. If for any
reason the pilot needs to use the brakes in an
emergency, having the Yellow circuit under
pressure is safer.
Start engine 2 by using the left mouse button to
move the ENG 2 master switch up. You can
monitor the start sequence via the E/WD and on
the SD ENG page that automatically appears. As
soon as engine 2 has started, you can start
engine 1 by moving the ENG 1 master switch up.
When engine 1 is started, you should return the
engine mode switch to the NORM position.
Note : If you are in Beginner mode, you can just
press Ctrl-E to start the engines, without
needing to start the APU. This function is
inhibited in Intermediate and Expert modes.
To stop the engines, the pilot just has to move
down each engine master switch. The crew
should make sure the APU is running before
stopping all engines because generators will
stop providing electric energy.
Engine Master Switch Usage in FS :
To move the engine master switches down
(engine off), you must use the right mouse
button and click the lower part of the switch. This
was done to prevent an unintentional engine stop
with a mouse click.
Restarting Engine in Flight
If an engine must be restarted in flight, the
crew can take advantage of the air bleed from
the engine that is still running. To do this, the
cross bleed valve must be opened by setting
the XBLEED switch on the OPEN position
(overhead, AIR COND section).
Air bleed is then available and the pilot can use
the engine mode switch and engine master
switch to start the engine as explained in the
previous paragraph.

INERTIAL REFERENCE SYSTEM (IRS)
The Inertial Reference System (IRS) provides
the aircraft position. To work properly, the
system must be aligned. The IRS measures
the aircraft accelerations and updates the
aircraft position, based on the original position
used during alignment.
IRS Alignment
The IRS are aligned through the INIT A page of
the MCDU (refer to the FMGC section for more
information about this page). As soon as the
FROM/TO airports are entered in the MCDU,
