Engines Flashcards
If you turn the ignition switch to OFF in flight, will the engine shut down?
No, FADEC disregards the ignition selector knob OFF position in flight
In flight the FADEC disregards the OFF position of the ignition switch (T/F).
True
When is a crossbleed start used, and what happens?
Used when the APU is not available and the bleed air from one engine is used to start the other
What happens to the bleed pressure DURING a crossbleed start after the operating engine thrust lever has been increased to provide adequate bleed pressure from the start?
Bleed pressure will drop and does not require the thrust lever to be adjusted to maintain pressure
Selecting the ignition switch to OVRD causes what to occur?
Activates both igniters on the ground or in filght
Placing the thrust levers in ________ position selects takeoff, maximum continuous, or go around settings
TO/GA
What methods are available for engine starting?
APU, ground source, opposite engine, windmill start
Where can engine oil quantity be checked?
MFD STATUS Page
If two consecutive overspeed detection events occur within 30 seconds the FADEC will not relight the engine (T/F).
False
If you turn the START/STOP selector to STOP in flight, will the engine shut down?
If the thrust lever is set to idle, the engine will shut down.
What position must the thrust lever be in to enable the thrust reverser trigger?
Idle
What controls the engine?
FADEC
What controls the engine start and provides hung start, hot start, and no light off protection?
FADEC
Does FADEC provide engine start protection?
On the ground for a hot start, hung start, or no light off
Is there protection for hot or hung starts in flight?
No
How are engine thrust ratings controlled?
By the FADEC
What does the cyan line on the N1 gauge represent on the approach?
The minimum N1 for bleed requirements in icing conditions
When does the icing cyan line on the N1 gauge appear?
When configured for landing in icing conditions at or below 1200 AGL on the radio altimeter
How is the N1 limit indicated on the EICAS?
Red tick mark on the N1 gauge
Where is external air for an air start connected?
Lower section in the wing fairing area
Will the crew have any indication when external air for an air start is connected?
Duct pressure is shown on the MFD status page
What happens after three overspeed detection events within 30 seconds?
FADEC will not re-light the engine
What does WML mean on the engine indication?
Windmilling engine
The FADEC has detected a flameout and the auto relight system is actuating to restart the engine
What does WML mean on the engine indication?
Windmilling engine
The FADEC has detected a flameout and the auto relight system is actuating to restart the engine
What is ATTCS?
Automatic Takeoff Thrust Control System
What does ATTCS provide?
Provides maximum thrust reserve (RSV) according to the current rate previously selected via the MCDU on the TO DATASET page
What will trigger an ATTCS event?
N1 difference >15%
Engine failure during a go around
Engine failure during takeoff
Windshear
What is ATTCS controlled by?
FADEC
When is ATTCS available?
Takeoff and go around
How can the pilot manually command RSV power?
By moving the thrust levers to MAX when the ATTCS is armed
What do the ATTCS buttons on the EICAS represent?
ATTCS labeled in white- system is armed
ATTCS labeled in green- system is engaged
When does the ATTCS system engage?
When the thrust levers reach the TOGA position
When is thrust reverse available?
Weight on wheels
When is the thrust reverser displayed on EICAS?
Whenever the thrust reverser is not stowed
Thrust reverser must be stowed below what speed?
60 knots
What does the green REV on EICAS mean?
Thrust reverser is fully deployed
What does an amber REV on EICAS mean?
Reverser in transition
What does a red REV indication on EICAS mean?
Discrepancy between selected and actual reverser position
What happens if a thrust reverser inadvertently deploys in flight?
FADEC limits respective engine thrust to IDLE
What position must the thrust levers be in to enable the thrust reverser trigger?
IDLE
If the thrust lever is placed in the MAX REV position and then released, what does it do?
It is spring loaded back to the MIN REV position
Can you deploy the thrust reverser on an engine that has failed on the landing roll?
Yes, up to 30 seconds following the failure, otherwise it is locked out
What is a Flex Thrust Takeoff?
Reduced thrust takeoff based on assumed temperature
What is the maximum flex allowed?
25% reduction
If you input a flex of 34, then change it to 39, how will it affect your N1 target?
It will lower the N1 target
Does the use of wet runway analysis numbers consider the increased stopping distance that occurs on wet runways?
Yes
If the thrust levers are not set to TOGA detent by 60 knots, which EICAS message will display?
TLA NOT TOGA
