Engines/APU Flashcards
The FADEC controls all but which of the following
Engine Anti-Ice
When the engines are running the FADEC is powered by
Its own alternator
The FADEC automatically_____ the igniters at each start
Alternates
During the automatic start sequence of ENG 1 you notice that only igniter A is powered IS this Normal
yes, igniters are used alternately for automatic engine start, in this case igniter A
If the FADEC detects a non normal condition during an automatic start with N2 below 50% it
Aborts the start and auto-cranks the engine
The FADEC normal control mode meters fuel to maintain a reference
EPR
The FADEC alternate control meters fuel to maintain a reference
N1
IF the EPR mode fails, the FADEC automatically reverts to the _____ mode
N1
Are engine limit protections provided in the N1 unrated Mode?
No protections are provided
Which is not a source of air for engine start
PTU
During a manual start _____ is not available
Automatic Abort
Verify a _____ bleed pressure indication during a manual start
Green
Durning a manual start, what function does the FADEC perform
Provides ECAM start fault detection, however, automatic abort and crank capabilities are not available
Which igniters is/are used during a manual start?
Both A and B
Why are both igniters powered during the ENG1 start sequence shown on the graphic
This is a manual start and both igniters are always used
What does a FAULT light indicate on the Engine Start and Ignition Panel?
Automatic aborted start
Continuous ignition is selected manually by positioning ENG MODE selector to
IGN/START
What action is required if continuous ignition is desired after engine start?
The ENG MODE selector must be cycled to NORM and then back to IGN/START
Continuous ignition NOT automatically provided for which of the following conditions
Turbulent Air
When is continuous ignition NOT automatically provided in flight
Engine low oil pressure indicated
How should you cancel a “ENG THR LEVERS NOT SET” caution during takeoff?
Advance the thrust levers to TO/GA
Which is NOT a position defined by a stop or detent
REV IDLE
The A/THR is armed on the ground by setting the thrust levers to _____ with at least one FD on
FLX with a FLEX temperature entered in the FMGC
The auto thrust will not arm when the thrust levers are advanced for takeoff if both _____ are off
FDs
Autothrust arming is confirmed when A/THR is displayed in _____ in the right column (column 5) of the FMA and the A/THR button is illuminated green
Blue
The A/THR is engaged in flight by
Setting thrust levers in the engagement range with the auto thrust system armed
The engagement range of the A/THR with both engines running is
Forward of IDLE to CL
The engaged mode of the A/THR is displayed in _____ in the left column (column 1) of the FMA
Green
An engaged auto thrust system reverts to which mode when the flight directors and autopilots are selected off
SPEED
The engagement range of the A/THR with one engine running is
Forward of IDLE detent to FLX/MCT detent
What action will not disconnect the auto thrust system?
Flying the airplane into an ALPHA FLOOR condition
How can a change in thrust be avoided when disconnecting the A/THR system
Matching the lever to existing power setting before disconnecting
Holding the auto thrust disconnect button for more than _____ seconds causes a loss of auto thrust system and loss of alpha floor protection for the remainder of the flight
15 seconds
The auto thrust system can be disconnected by
Positioning both thrust levers to the idle stop
Thrust lock is caused by
Failure of the A/THR system
After recovery from an alpha floor engagement, _____ is annunciated in the green on the FMA
TOGO LK
How can thrust control be regained after a TOGA LK condition
Disconnecting the Autothrust system
The A/THR RETARD mode is only available during a/an ______ landing
Automatic
According to the graphic, what is the condition of the engines
Reverser doors are not stowed or are unlocked
The majority of the APU system logic is controlled by
Electronic Control Box (ECB)
The APU start sequence
Is completely automatic once initiated
While preflighting with the APU running, you hear a horn in the nose wheel the may indicate
An APU fire
During the initial flight deck preparation you notice an illuminated APU MASTER switch FAULT light. What does this indicate
APU has shut down automatically
Fuel is normally supplied to the APU from
The left fuel feed line
APU my be started by using normal electrics up to
39,000 feet
When the APU MASTER switch is selected OFF, the APU may continue to run for up to _____ minutes to cool before shutdown
2
The APU MASTER switch FAULT light illuminates amber when
An APU automatic shutdown occurs
An APU auto shutdown occurs and an APU MASTER switch FAULT light illuminates amber for which of the following
APU overspeed or under speed
What pilot actions are required for an APU fire on the ground
Follow ECAM procedure. APU auto shutdown and fire extinguishing is automatic
