ENG MODE selector on NORM, igniters A and B come on automatically when engines are running and:
During deployment, engine reverse thrust is limited to idle, until the reversers are fully deployed.
During deployment, engine reverse thrust is limited to idle, until the reversers are deployed by more than 78 %. Then, FADEC will command full reverse thrust to be available when reversers position are more than 90 % deployed.
If the automatic start fails the FADEC energizes both igniters at the same time during the second attempt at an engine start.
When the ENG MODE selector is on IGN/START position and if the ENG MASTER is not switched on, within 30 seconds:
CONTROLS AND INDICATORS - ENGINE DISPLAY IDLE INDICATION - Both engines are at idle speed, and the aircraft is in flight.
After an engine failure during takeoff using FLEX thrust, to activate A/THR and to get MCT, pilot:
The reverse thrust system is actuated by:
Reverse thrust is obtained by deflecting the fan airstream. This is done when the translating cowls are fully-deployed backward. This action therefore enables the pivoting blocker doors to divert the fan flow forward through the cascades.
What is the true statement about the electrical supply of the FADEC?
If the ENG MODE selector is turned to the CRANK position:
In case of takeoff without FD using FLEX thrust:

The Variable Stator Vannes (VSV), Variable Bleed Valves (VBV) and Burner Staging Valve (BSV) that optimize the engine ratio, control the clearance and igniters, are activated by:
The FADEC will automatically command the reverser to stow if at least one cowl is unstowed by more than _____ and reverse thrust is not selected while engine is running.
The engine Accessory Gear Box (AGB) provides power for the:
The CLB thrust limit mode indication is displayed on EW/D when:
If the first engine start fails:
The ignition is automatically cut off when N2 is:
Approach idle depends:
The FADEC has two modes of power setting, EPR and N1 modes.
During climb phase, A/THR active, pilot sets thrust levers on IDLE:
The Idle modes provided by the Full Authority Digital Engine Control (FADEC) are:

When performing a manual dry ventilation, the start valve will close:
Engines running, thrust levers are set between IDLE and CLIMB, the FADEC calculated N1 is equal to TLA and N1 is limited to:
The oil system lubricates the engine components. The oil is cooled:
During reverse operation, the thrust is controlled as a function of EPR.
During reverse operation, the thrust is controlled as a function of N1.
High engine vibration may be accompanied by cockpit and cabin smoke and/or the smell of burning. This may be due only to compressor blade tip contact with associated abradable seals.
A manual start sequence can be initiated _____ following a dry crank sequence by selecting the ENG START selector to IGN/START and ENG MASTER switch to ON.
The EGT limit does not appear:
Flying with A/THR active, pilot sets thrust lever to TO/GA position:
The ENG MASTER switch controls:
The Full Authority Digital Engine Control (FADEC) provides engine protections:

The Full Authority Digital Engine Control (FADEC) displays its engine parameters and information on:
Each engine fuel system has LP and HP Fuel Valves:
On ground before starting engine, when the flight crew selects the ENG MODE selector to IGN/START:
Which one of the following statements is true?
To allow the engine to accelerate rapidly from Idle to go-around thrust, FADEC selects approach idle:
What does the blue A/THR indication on FMA mean?
Setting the ENG MASTER switch to OFF directly commands the closing of the LP and HP fuel shutoff valves for that engine’s fuel system.
The IDG oil cooling system is ensured by:
IDG oil cooling is ensured by the IDG fuel/oil heat exchanger using fuel flow from the fuel pump unit and, from the FMU through the fuel bypass valve at low engine power only.
LVR MCT is flashing on the FMA if the thrust levers are not set in MCT detent:
Which of the following statements is true?
FADEC has two-channel redundancy, with one channel active and one standby. If one channel fails, the other automatically takes control. The system has a magnetic alternator for an internal power source. FADEC is mounted on the fan case.

After takeoff with FD on, when the thrust levers are in FLEX detent:
During a manual start up sequence, the ignition is performed by:
In case of inadvertent engine shutdown by cycling the Engine Master lever to OFF then ON, the FADEC will attempt automatically a relight regardless of the rotary selector position.
After takeoff, if thrust levers are left in FLEX/MCT detent:
After takeoff, the pilot can change from FLX to MCT by moving the thrust lever to TOGA or CL, then back to MCT. After that, the FLX rating cannot be used.
Setting the thrust lever out of the MCT/FLX detent, without reaching TOGA or CL detent, has no effect.
Internal engine fire may be encountered during engine start or engine shutdown. It may be seen by the ground crew, or the EGT may fail to decrease after the ENG MASTER lever is turned off. The flight crew shall not press the ENG FIRE pb-sw, since this would cut off the FADEC power supply, which would prevent motoring sequence.
External fire agents can cause severe corrosive damage. Consider the use of external fire agents only if the following procedure does not stop engine tailpipe fire.
