Answer 5

TO/GA.

Question 6

What does pressing the EVENT MARKER button cause the FADEC to do?

Answer 6

FADEC records three minutes of engine data, two minutes before and one after pressing the button.

Answer 11

On the ground with wheel speed.

What icon on the EICAS indicates the current status of the thrust reverser?

Answer 12

REV icon.

Question 13

Answer 16

Cyan IGN OFF.

Question 17

Where can the oil level be accurately read?

Answer 17

Either the site glass or Remote Oil Level sensor on EICAS.

Question 18

When can the oil level be accurately read?

Answer 18

5 to 30 min after engine shutdown.

Question 19

Is the oil quantity indication visible with an engine running or inflight?

Answer 19

No.

Question 20

What is the maximum oil consumption rate of the engine?

Answer 20

0.04 qts per hr.

Question 21

List the three sources of air pressure for engine start?

Answer 21

APU, ground air cart or opposite engine.

Question 22

What is the purpose of the Automatic Takeoff Thrust Control System (ATTCS)?

Answer 22

The ATTCS function is available to provide automatic thrust increase in case One Engine Inoperative (OEI) condition is detected for takeoff or go-around.

The ATTCS thrust increase is to provide a lower N1 debit when the
WAI bleed increases from a dual source to a single source condition,
resulting in an ITT increase of approximately 30°C.

Question 23

When is the ATTCS function available?

Answer 23

Only when the WAI is on.

Question 24

Which takeoff thrust settings may be selected prior to takeoff?

Answer 24

Full rated T-01 and detracted T-02.

Question 25

List the engine power settings that may be selected by the flight crew?

Answer 25

TO/GA, CON (max continuous), CLB, CRZ and reverse.

Question 26

What are the starting and motoring limitations?

Answer 26

Max accumulated time - 5 min
Max cycles - 3
15 min cooldown after whichever occurs first.

Starter Duty Cycle - 80 sec max

Question 27

Can the engine be started with the ITT above 450° C?

Answer 27

Yes.

CAUTION:
IF ENGINE ITT IS ABOVE 450°C BEFORE STARTING CYCLE, DRY MOTORING THE ASSOCIATED ENGINE FOR 30 SECONDS PRIOR TO START.

Question 28

When can HP thermal bow occur? What is the recommended procedure if engine restart is desired within that period?

Answer 28

CAUTION: IF ENGINE RESTART IS DESIRED BETWEEN 15 AND 180 MINUTES AFTER AN ENGINE SHUTDOWN, IT IS RECOMMENDED DRY MOTORING THE ASSOCIATED
ENGINE PRIOR TO START FOR 15 SECONDS OR UNTIL N2 REACHES 23%, WHICHEVER OCCURS FIRST. AFTER COMPLETION OF THIS PROCEDURE, A NORMAL ENGINE START SEQUENCE CAN BE INITIATED ANY TIME AFTER 3 MINUTES AND BEFORE 40 MINUTES HAVE ELAPSED.
