-
What happens when the ignition switch is selected to override?
Activates both igniters on the ground or in flight
-
Can the igniters Be turned off during flight?
The switch may be turned to the off position, but the FADEC disregards the command.
-
What controls the engine?
The FADEC
-
What controls engine starting and provides hung start, hot start and no light off protection?
The FADEC
-
Does the FADEC provide engine start protection?
Only on the ground, HOT, HUNG, NO LIGHT OFF
-
Is there protection for HOT or HUNG starts during an in flight start?
No
-
How are engine thrust ratings controlled?
By the FADEC
-
What does the cyan line on the N1 gauge represent during the approach? When does it appear?
- Min N1 req for icing conditions
- Configured when anti ice is ON
-
How is the N1 limit indicated on the EICAS?
Red tick mark on N1 gauge.
-
What sources are available for engine starting?
- APU
- Ground source
- Opposite engine
- Windmill start
-
Where is external air for an air start connected? Will crew have an indication that the external air is connected?
- Lower section of the wing fairing area.
- Duct pressure on mfd synoptic page.
-
What happens after 3 over speed detection events within 30 sec?
FADEC will not relight the engine
-
What does WML mean on the engine indication?
- Windmilling engine
- The FADEC has detected a flame out and the auto relight system is actuating to restart the engine.
-
Where can the crew check the engine oil qty?
On the MFD synoptic page
-
What is ATTCS.? What controls it?
- Automatic takeoff and thrust control system
- Provides max thrust reserve according to current rate previously selected via the mcdu on the TO DATASET page
- Controlled by the FADEC
- Engagement only happens when the thrust levers reach the TOGA set position.
-
What will trigger an ATTCS event?
- N1 difference greater than 15% between the engines
- Engine failure during TO or Go around
- Wind shear detection
-
How can the pilot command RSV power?
By moving the thrust levers to the max position whenever the ATTCS is armed.
-
When is thrust reverse available?
Wow
-
Thrust reverser must be stowed below what altitude?
60 KIAS
-
When is the thrust reverser displayed and what do the colors mean?
- Whenever thrust reverser is not stowed
- Green is fully deployed
- Amber is in transition
- Red means that there is a discrepancy between indicated and actual positions
-
What position must the thrust lever be in to enable the thrust reverser trigger?
Idle
-
If the thrust reverser is placed in the MAX rev position and then released, what happens?
It is spring loaded back to the Min rev position
-
What happens when a thrust reverser inadvertently deploys?
The FADEC limits the respective engine to idle.
-
Can you deploy the thrust reverser on an engine that has failed on the landing roll?
Yes, up to 30 sec. then it is locked out
-
What is FLEX to?
Reduced thrust takeoff based on assumed temp
-
What is the max flex allowed?
25%
-
If you input a flex of 34,then change it to 39 how will it affect N1 target?
It will drop your N1 target
-
Use of reduced to procedures is not allowed on?
- Runways contaminated with standing water, slush, snow or Ice.
- Wet runways unless wet numbers to account for increased stopping distance are obtained
-
Can you FLEX with WSHR advisory in affect?
No
-
FLEX to is prohibited when?
- Runway is contaminated
- Windshear advisories are in effect
- Runway performance doesn’t allow for FLEX to
-
Do Wet numbers take into account the increased stopping distance which occurs on wet runways?
Yes
-
If you turn the START/STOP to stop in flight, will the engine shutdown?
Not until thrust lever is idle
-
When is a cross bleed start used and what happens?
When APU bleed is not available, bleed air from one engine starts the other
-
What happens to bleed pressure during a cross bleed start?
Bleed pressure will drop.
It is not required to advance the throttle if this occurs
-
Before apply TO thrust, allow the engines to warm up for a minimum of how many mins?
2
-
How long must an engine cool down prior to shutting it down?
2
-
What are the EICAS engine limit display markings?
- Red is Min and Max limits
- Amber is caution
- Green is normal
-
Memory item for ENGINE ABNORMAL START
# START/STOP. ............ STOP
