Powerplant (SYS2)

Question 1

When positioning the START/STOP selector knob STOP to START how long should the knob be paused in the RUN position prior to STOP

Answer 1

2 seconds

Question 2

How is light-off recognized during engine starts

Answer 2

An increase in the digital readout of the ITT indicator

Question 3

When should the ignition be placed to ON?

Answer 3

Standing Water, Ice, Slush, or Snow on the runway
When the temperature is below 10*C and the engine have been shut down for more than 90 min
As directed by the QRH

Question 4

What is the minimum oil quantiles needed for take off

Answer 4

Engine Start or leaving the hub 8 qts
Leaving the outstation 7 qts
Take off 6 qts

Question 5

With what EICAS messages should the takeoff be aborted

Answer 5

E 1(2) ATTCS NO MRGN
E 1(2) LOW N1
ENG 1(2) REV DISAGREE
ENG 1(2) REV FAIL
ICE COND-A/I INOP

Question 6

When should the engine start be aborted

Answer 6

No light off within 10 seconds after fuel flow (ground only)
ITT approaches start limit
N2 decreased or remains steady for more than 30 seconds
N2 indicates no rotation up to 10 seconds after the start command
Any unusual noise or vibration
Engine instruments indicate abnormal conditions
Flames are visible from the exhaust pipe
Oil pressure does not reach 34 PSI after engine reaches stabilized idle

Question 7

What are indications of Severe Damage

Answer 7

No N1 rotation, High ITT, High Vibration, High Oil Temperature, Low Oil Quantity, High Oil Pressure, E1 (2) FIRE DET FAIL messages, smoke, abnormal noise of vibration

Question 8

All though ideally there would be none, what time of fluid could be present in the sight gauge underneath the engine

Answer 8

Oil, fuel, hydraulic, water.

Unless there is fluid dripping from the holes around the sight glass mast there is not need to call maintenance.

Question 9

Of the following thrust ratings, which is not selectable via the T/O data setting function?
ALT-T/O, T/O, E-T/O, T/O-RSV

Answer 9

T/O-RSV

Question 10

What thrust ratings are available for the XR using the T/O data setting function

Answer 10

ALT-T/O, T/O, E-T/O

Question 11

Where can engine oil quantity be monitored?

Answer 11

MFD T/O Page

Question 12

What components are located in the engine’s accessory gearbox

Answer 12

(2) Engine driven generators
(1) Oil Pump
(1) Hydrualic Pump
(1) Fuel Pump
(1) Permanent Magnet Alternator
(1) Air turbine Starter

Question 13

What happens when a thrust reverser deploys in flight?

Answer 13

The FADEC reduces the engine thrust to idle

Question 14

What happens to the engine when the FADEC in control fails

Answer 14

The other FADEC takes over

Question 15

What happens when both FADEC’s for and engine fails?

Answer 15

An engine shutdown would occur.

Question 16

When the landing gear is lowered below 15,000’, which target thrust rating will the FADEC default to?

Answer 16

The highest thrust rating a pilot could select for takeoff is T/O and E-T/O. Going past the detent during a go around the A1P would command a T/O-RSV

Question 17

Should an Engine Start Procedure be aborted if E1(2) ATS SOV OPEN message is presented?

Answer 17

No

Question 18

Explain the Start sequence of the engine

Answer 18

After Start Verify N2 within 10 seconds and oil pressure rise
At 14%N2 verify ignition on
At 28.5%N2 or 12 sec after ignition verify fuel flow
Monitor ITT for light off within 10 seconds of Fuel Flow and verify N1 rotation
Fuel Flow and ITT should rise around 31.5%N2
Monitor ITT, N2. and Oil Pressure throughout the start
Engine start cycle ends at 57%N2

Question 19

Are any Engine EICAS messages inhibited during takeoff roll?

Answer 19

FROM V1-15 to 400' AGL and Approach and landing:
E 1(2) ATTCS NO MRGN 
E 1(2) LOW N1
ENG 1(2) REV DISAGREE
ENG 1(2) REV FAIL
ICE COND-A/I INOP
