Subtask 10.1.3 Operate Engines

Question 1

What type of engine does the ERJ have?

Answer 1

GE CF34-8E5 high bypass, dual rotor turbofan, controlled via dual channel FADEC

Question 2

When will the thrust modes automatically change?

Answer 2

• TO to CLB
Landing gear retracted, airplane above 400’ AGL, any change in vertical mode

•CLB to CRZ
Airplane is level at preselected altitude for 90 s, airspeed within 5 kts (.01M) from preselected

• CON
Automatically if engine fails >= 3,000’ AGL

•CRZ to GA
Flaps are > 0 and gear down
OR
When TOGA is pressed

Question 3

What is ATTCS?

Answer 3

Automatic takeoff thrust control system. When enabled, will command higher thrust in various phases of flight

Question 4

When will ATTCS engage?

Answer 4

•T/O dataset menu set to ON, Thrust levers are at TO/GA position, difference between N1 >15%

•T/O dataset menu set to ON, Thrust levers are at TO/GA position, one engine failure during T/O

• T/O dataset menu set to ON, Thrust levers are at TO/GA position, one engine failure during GA

• T/O dataset menu set to ON, Thrust levers are at TO/GA position, windshear detection

NOTE: RSV mode is manually engaged by moving thrust levers to MAX position

Question 5

Recite engine abnormal start memory items.

Answer 5

AFFECTED ENGINE: START/STOP SELECTOR……………………………………………………….. STOP

Question 6

When will FADEC automatically abort an engine start?

Answer 6

FADEC automatically aborts an engine start for hot start, hung start, no light off

Hot start= ITT exceeds start limit (815c)

*Hung start= N1 and/or N2 failing to accelerate to stable idle speed

*No light off= No ITT indication within 30s after initiation of fuel flow
