When the APU is started, a green 'AVAIL' light
replaces the blue 'ON' light on the START
switch. An 'AVAIL' message appears on the
APU page and an ECAM message displays
'APU AVAIL'. The APU is now ready to provide
air and electricity.
The APU can be started at any altitude and at
any airspeed.
The APU fuel consumption is around 100kg per
hour.

used to start the engines. To do this, the crew
must press the APU BLEED button in the AIR
COND overhead section (see the Air section for

POWER PLANTS
The engines are managed by the Full Authority
Digital Engine Control (FADEC). This device
controls the engine during the start sequence
and during the flight to provide optimal usage.
Engine Monitoring
Engine status is monitored through the
Engine/Warning Display (E/WD), which
displays essential engine and FADEC
information. Information is also available
through the Engine and Cruise page of the SD.
Depending on the engine type and EFIS
generation, the E/WD can have different
layouts. Refer to the EFIS section for more
details. Anyway, the most important engine
information is always displayed on the E/WD.
On this example, N1, EGT, N2 and Fuel Flow
are displayed. In addition, FADEC information
is displayed: the mode, which depends on the
thrust lever detent, and the max N1 that
depends on this mode.
In addition, engine information is displayed on
the ENG page :
1. Fuel used by each engine since last
startup.
2. Oil quantity, in quarts
3. Oil pressure, in Pound per Square Inch (PSI)
4. Oil temperature
5. Vibration on the first compressor stage
