MENU POWER PLANT (IAE) MENU Normal operation A 20/72 No, to switch on the engine IGN/START function, move the engine mode selector to the IGN/START position. POWER PLANT (IAE) MENU Normal operation A 21/72 No, to switch on the engine IGN/START function, move the engine mode selector to the IGN/START position. POWER PLANT (IAE) Normal operation A 22/72 When ignition start is selected, the FADECs are powered again. This is indicated on the E/WD by the indications which change from amber to normal. MENU POWER PLANT (IAE) Normal operation A 23/72 On the system display, the ECAM ENGINE page is automatically presented for more engine indication. MENU POWER PLANT (IAE) Normal operation A 24/72 The first indications on the E/WD are the Engine Pressure Ratio (EPR) for each engine. Both indicators are identical. MENU POWER PLANT (IAE) Normal operation A 25/72 The green needle indicates the actual EPR. This value is also displayed digitally.

This will be explained and demonstrated as the mode changes later in the module. MENU POWER PLANT (IAE) MENU Normal operation A 30/72 The next set of indicators display the Exhaust Gas Temperature (EGT) of each engine. POWER PLANT (IAE) MENU Normal operation A 31/72 Here is a typical EGT in cruise. The green needle indicates the actual EGT . This value is also displayed digitally . POWER PLANT (IAE) MENU Normal operation A 32/72 The amber tick indicates the maximum EGT (MAX EGT). Since the MAX EGT is different for starting, TO, CL, Cruise, etc.., the tick moves automatically depending on the phase of operation. Note: the amber tick is not displayed during take off.

POWER PLANT (IAE) MENU Normal operation A 34/72 POWER PLANT (IAE) Normal operation A 35/72 Let’s look at the indications on the ECAM ENGINE page. The first indication displayed is the fuel used by each engine. Notice that there is fuel used and we have not started the engines. This is because this value is frozen at engine shut down and reset on the ground, at engine start. MENU POWER PLANT (IAE) Normal operation A 36/72 The next indications are: - the engine oil quantity, - the oil pressure , - and the oil temperature. MENU POWER PLANT (IAE) Normal operation A 37/72 Vibration indications are displayed on the right side of the ECAM ENGINE display. MENU POWER PLANT (IAE) MENU Normal operation A 38/72 POWER PLANT (IAE) MENU Normal operation A 39/72 POWER PLANT (IAE) Normal operation A 40/72 There are additional indications, displayed during engine start on the ground. They are only displayed when the ENG MODE SEL is in the IGN/START or CRANK position. They are: - the start valve position indications, - and the air pressure available for start . MENU POWER PLANT (IAE) Normal operation A 41/72 We will start the engines using the available APU BLEED as indicated in the MEMO and the pressure indication at the bottom of the SD. We start engine 2 first because the Yellow hydraulic system engine driven pump is on engine 2 and the YELLOW system supplies park brake pressure. Swiittcchh oonn eennggiinnee 22..

Approximately 50 seconds after selecting engine 2 master switch ON an igniter is powered. The active igniter is indicated by a letter (A or B) on the ECAM ENGINE page. Note: the igniters alternate on successive starts. MENU POWER PLANT (IAE) MENU Normal operation A 50/72 POWER PLANT (IAE) Normal operation A 51/72 On the E/WD we see that the fuel flow begins. When the fuel is ignited, the EGT increases. MENU POWER PLANT (IAE) Normal operation A 52/72 When N2 reaches 43%, the start valve closes and the ignition is switched off. Notice on the ECAM ENGINE page the start valve is closed and the igniter indication disappears. MENU POWER PLANT (IAE) Normal operation A 53/72 N2 continues to increase. At approximately 58% it stabilizes and the grey background disappears indicating that the start sequence is finished. ENGINE 2 is now running and all its parameters have stabilized.
