Engine Flashcards
If you turn the Ignition switch off in flight, will the engine shutdown?
NO, Fadec Disregards the Off position in flight
When is a crossbleed start used?
to start an engine without APU, Crossbleed from other engine
Selecting the Ignition to OVRD does what?
turns on Ignitors on ground or in flight.
placing the thrust levers in TOGA does what?
Selects Takeoff, Go around and max continuous power.
What are methods for engine starting?
-Ground power cart (Huffer)
-APU
-CrossBleed start
-Windmill
Where can engine oil be checked?
MFD Status page
If the START/STOP switch is placed to STOP in flight will the engine shut down?
Yes IF power lever is Idle
What controls the engine?
FADEC
What does Cyan line on the N1 gauge represent?
Minimum N1 for bleed requirements Anti Ice
When would the Cyan line on N1 appear?
Configured for landing in Icing conditions below 1200FT
How is n1 limit indicated on EICAS?
Red tic mark on n1 gauge
where is external air connected for air start?
lower section of the wing fairing
Will crew have any indication that the Air cart is connected?
yes, air duct pressure on the MFD status
what happens after 3 overspeed detections event within 30 seconds?
FADEC will not relight engine
What does WML mean on the engine indication?
Windmilling engine, fadec detects a flame out and auto relight is actuating to start the engine
what is ATTCS?
Automatic takeoff thrust control system
What does ATTCS do?
provides maximum thrust reserve according to TO DATASET in MCDU
What controls ATTCS?
FADEC
What will trigger an ATTCS event?
N1% Difference >15% between engines
Engine Fail during Takeoff or Go-Around
Windshear detection
When is ATTCS available?
Takeoff or Go around
When does ATTCS system engage?
when Thrust levers reach the TOGA position
What does it mean when ATTCS is indicated in white lettering?
ATTCS is armed
What does it mean when ATTCS is indicated green?
ATTCS is engaged
When is thrust reverse available?
Weight on Wheels
What does Green REV on EICAS mean?
Thrust reverse is fully engaged
What does Amber colored REV indication mean?
Thrust reverse is in transition
What does Red colored REV Indication mean?
discrepancy between actual reverse and levers
What happens if thrust reversers inadvertantly deploys in flight?
FADEC limits thrust on that engine to Idle
What position must power lever be in to pull the reversers into reverse thrust?
Idle
can you deploy thrust reversers on a failed engine?
Yes for up to about 30 seconds
What is a flex thrust Takeoff?
a Takeoff with reduced thrust (based on assumed temps)
what is the maximum flex allowed?
25%
if you input a flex number higher than the original, what happens to your N1%?
It lowers the target.
