PNEUMATIC MENU Normal Operation 1/62 PNEUMATIC MENU Normal Operation 2/62 PNEUMATIC MENU Normal Operation 3/62 You are in the Preliminary Cockpit Preparation phase. To better illustrate what occurs in the pneumatic system, select the ECAM BLEED page using the ECAM control panel. PNEUMATIC MENU Normal Operation 4/62 You are in the Preliminary Cockpit Preparation phase. No. Press the BLEED key on the Ecam Control Panel. PNEUMATIC MENU Normal Operation 5/62 You are in the Preliminary Cockpit Preparation phase. No. Press the BLEED key on the Ecam Control Panel. PNEUMATIC MENU Normal Operation 6/62 Let’s talk about the indications on the ECAM BLEED page... PNEUMATIC MENU Normal Operation 7/62 The engine identification numbers are displayed amber because the engines are not running. PNEUMATIC MENU Normal Operation 8/62 PNEUMATIC MENU Normal Operation 9/62 During preliminary cockpit preparation all white lights must be extinguished. With the ENG BLEED pb sw in the lights out position, the bleed valves are automatically controlled by the system. Observe the symbology on the ECAM. The bleed valves are cross-line green because they are fully closed. PNEUMATIC MENU Normal Operation 10/62 The HP valves are also automatically controlled by the system. They are displayed crossline green to indicate that they are fully closed. PNEUMATIC MENU Normal Operation 11/62 The bleed temperature is displayed in green. The bleed pressure is displayed in amber because there is no pressure supplied. PNEUMATIC MENU Normal Operation 12/62 The GND HP connection indication is always displayed in green when the aircraft is on the ground whether the GND unit is connected or not. PNEUMATIC MENU Normal Operation 13/62 You also have to check that the X BLEED selector is in AUTO position. Observe the indication on the ECAM. The X BLEED valve is displayed cross-line green because it is automatically closed by the system. PNEUMATIC MENU Normal Operation 14/62 Since the APU BLEED pb sw is selected off, the APU BLEED valve is displayed cross-line green, indicating that it is closed. PNEUMATIC MENU Normal Operation 15/62 The next step during Cockpit Preparation is to switch the APU BLEED on. We have already started the APU for you. Swiittcchh APU BLLEED oonn !! Note : Do not use APU BLEED if GND HP air is connected. PNEUMATIC MENU Normal Operation 16/62 The next step during Cockpit Preparation is to switch the APU BLEED on.

PNEUMATIC MENU Normal Operation 24/62 The next step is the walk around. If ground high pressure air is not required, you have to check that the high pressure ground connection door is closed. PNEUMATIC MENU Normal Operation 25/62 Usually, APU bleed air is used for engine start. The pressure displayed on the BLEED page is also indicated on the ECAM ENGINE page which will be explained in the ENGINE chapter.

POWER PLANT (IAE) MENU Manual Start 1/31
POWER PLANT (IAE) Manual Start 2/31
We will see now, how to manually start the engines.
There are several reasons why a manual start may be
required including low pneumatic pressure.
The main difference between a manual and an automatic
start is that the pilot controls the time at which fuel and
ignition are supplied to the engine.
The FADEC only provides passive monitoring of the engine
during the start sequence. This means that responsibility for
preventing an over limit start remains with the pilot.
Note: Manual starts are completed using the procedure detailed
in FCOM 3- procedures and techniques
MENU
POWER PLANT (IAE) Manual Start 3/31
The FADEC controls:
- the closure of the start valve at 43 % N2
- and ignition cut off on the ground.
MENU
POWER PLANT (IAE) Manual Start 4/31
The configuration is the same. On the E/WD, all indications
related to the engines are displayed in amber as long as the
FADECs are not powered.
In order to start the engines, the engine mode selector must
be switched to IGN/START position first.

-the ENGINE ECAM page is displayed automatically.

We will start engine 2 using the APU BLEED.
The ENG MAN START pb switches control their respective
start valves. To start engine 2, raise the guard and select ENG
MAN START 2 pb switch.
Note: PF should start his chrono when he selects the ENG MAN
