and go-around thrust and mode settings?
TO/GA (AOM 9-06-30)
What does pressing the EVENT MARKER button
cause the ECU (FADEC) to do?
Record for a total of 3 minutes (2 minutes
before pressing the button and 1 minute after
the EVENT MARKER button is pressed)
(AOM 9-06-30)
When is the OAT on the EICAS indication displayed?
Up until the takeoff run (AOM 9-06-30)
What are the thrust reversers used for and during
what phase of flight?
An on-ground additional braking device used for
landing and RTO only (AOM 9-06-60)
Is backing up the airplane with reverse thrust allowed?
No, it is prohibited (AOM 2-40)
Upon landing, when should the thrust reversers
be stowed?
At 40 kts (AOM 2-40)
When are the thrust reversers available?
With WOW signal indicating that the airplane is
on the ground and a wheel speed (AOM 9-06-60)
What icon on the EICAS indicates the current
status of the thrust reverser?
A REV icon (AOM 9-06-30)
What color icon indicates that the thrust reversers
are commanded and deployed?
A green REV (AOM 9-06-30)
What color icon indicates that the thrust reversers
are commanded and in transition?
An amber REV (AOM 9-06-30)
Where is the IGNITION status displayed?
On the EICAS (AOM 9-06-30)
What does a green IGN indicate?
The igniters are commanded on (AOM 9-06-30)
What icon on the EICAS indicates that the igniters
are commanded to OFF?
A cyan IGN OFF (AOM 9-06-30)
Where can the oil level be accurately read?
Either in the sight glass or measured via the
Remote Oil Level Sensor (ROLS) (AOM 9-06-30)
When can the oil level be accurately read?
From 5 to 30 minutes after engine shutdown
AOM 9-06-30
Is the engine oil quantity indication visible with an
engine running or in flight?
No, it is hidden. (AOM 9-06-30)
What is the maximum oil consumption rate of the
engine per hour?
0.04 quarts (or 1 quart per 25 hours)
AOM 9-06-50
List the three sources of air pressure that the Air
Turbine Starter can use for an engine start.
The APU, an opposite engine or a ground air
supply (AOM 9-06-55)
What is the purpose of the Automatic Takeoff
Thrust Control System (ATTCS)?
To provide automatic thrust increase if ATTCS
is previously armed and any one of the following
conditions is true on takeoff or go-around—OEI
condition is detected (N2 difference between
engines is greater than 15%); Loss of engine
cross-communication; Windshear is detected; Thrust lever is moved to the MAX position
(AOM 9-06-70)
When is the ATTCS function available
When WAI is ON “ICE PROT mode knob in ALL”
AOM 9-06-70
Which takeoff ratings may be selected by the
flight crew prior to takeoff?
The full rated mode (TO-1) and the one de-rated
mode (TO-2) (AOM 9-06-70)
List the engine power settings that may be selected
by the flight crew.
Takeoff/Go-Around (TO/GA), Maximum Continuous
(CON), Climb (CLB), Cruise (CRZ), Maximum
reverse (for landing or a rejected takeoff)
What are the starting and motoring limits?
Max accumulated time—5 minutes; Maximum
consecutive cycles—3; After reaching five
minutes of accumulated time or three cycles
(whichever occurs first), combining consecutive
engine starting and motoring, 15 minutes of cool
down time is required prior to additional engine
start or motoring. (AOM 2-40)
What are the starting duty cycle limits?
Maximum time of 80 seconds. (AOM 2-40)
How many consecutive starts are allowed before
a cooling time of 15 minutes is required prior to
additional starts or motoring?
3 (AOM 2-40)
Can the engine be started with an ITT above
450°C? If so, what must be accomplished prior to
start?
Yes, dry motor the associated engine for 30
seconds prior to start (AOM 3-11)
When can HP thermal bow occur? If an engine
restart is desired within that time period,what is
the recommended procedure?
When engine starts are initiated between 15
and 180 minutes after an engine shutdown. Dry
motor the associated engine prior to start for
15 seconds or until N2 reaches 23% (whichever
occurs first). After completion of this procedure,
a normal engine start sequence can be initiated
any time after 3 minutes and before 40 minutes
have elapsed. (AOM 3-11)
