Question 1

When should the engine oil be checked?

Answer 1

5-30 minutes after engine shutdown.

Question 2

What do you see during a normal TR deployment?

Answer 2

White REV in N1’s (in transit) followed by green REV in the N1’s(deployed).

Question 3

When is APR armed?

Answer 3

When Thrust levers are in the TO detent.

On Approach when flaps are greater than 20 degrees or the gear is down.

Question 4

When is APR activated?

Answer 4

a spilt in N2’s of 15% or more is detected.

Question 5

What is the time limit in APR when automatically activated?

Answer 5

10 Minutes

Question 6

What is the time limit in APR when manually selected?

Answer 6

5 minutes.

Question 7

When would you manually select APR?

Answer 7

Stall, Windshear, TAWS event, unusual attitudes.

Question 8

If APR is activated, is there a wear and tear factor?

Answer 8

YES. 5 cycles and 10 hours added to engine(s) per event.

Question 9

What does FADEC protect against on the ground during engine start?

Answer 9

HOT START
HUNG START
NO LIGHT OFF

** There is no FADEC protection for inflight starts…

Question 10

Max ITT for start?

Answer 10

650 degrees

Question 11

Max ITT to initiate a start?

Answer 11

350° C

Question 12

What happens automatically to thrust reversers below 85 kts?

Answer 12

FADEC will reduce thrust to arrive at idle thrust at 40 kts regardless of TR lever position.

Question 13

In order for Engine sync to be activated what must occur?

Answer 13

The slave engine must be within 5% of the Master engine.

Question 14

What parameters must be met in order for Mac Hold to be active?

Answer 14

N1 or N2 synchronized

Aircraft trimmed for steady level flight

Autopilot engaged in either Altitude Hold or Altitude Select (with altitude captured)

Question 15

Mach Hold authority only allows N1 to be adjusted within:

Answer 15

+/- 3%

** with MACH HOLD selected and outside the 3%, MACH HOLD green goes away and is replaced by a green SYNC.

Question 16

What is the ballpark fuel burn for the first 3 hours of flight?

Answer 16

1st hour: 2600#
2nd hour: 2000#
3rd hour: 1800#

Question 17

What is the kevlar containment ring for?

Answer 17

If the Fan section of the engine separates, the containment ring prevents fragments from penetrating the pressure vessel.

Question 18

When the stick-shaker activates due to excessive AOA, what happens automatically?

Answer 18

FADEC fires both igniters and modulates engine thrust to try to prevent compressor stall.

Question 19

What warnings can you expect during an engine fire?

Answer 19

1. Master Warning Lights
2. L/R ENGINE FIRE CAS msg.
3. Red FIRE inside N1 indicaors.
4. Fire Switch Light illuminates
5. Aural “ENGINE FIRE”

Question 20

How many consecutive ENGINE starts can you do?

Answer 20

3, with 30 second of motoring (cooling) in between starts, then 15 minutes cooling.

Question 21

What is the primary method of checking engine oil?

Answer 21

At the refuel Panel or Remote Oil Level Sensors (ROLS)

**there is a sight gage in each engine (secondary way of checking oil level)

Question 22

During a normal start, when does the start valve close and the ATS (AIR TURBINE STARTER) disengage?

Answer 22

50% N2

Question 24

Why is there no need for PRIST?

Answer 24

A Fuel Heater/Oil Cooler (FHOC) heats the fuel and cools the engine oil. (Heat Exchanger)

Question 25

When should we manually turn on the igniters?

Answer 25

Acronym TRCT

T- Thnderstorms
R - Rain (heavy)
C - Contaminated Runways
T - Turbulence

Both Igniters A and B fire.

Question 26

Answer 26

7372 # of thrust.

Question 27

What is the time limit in the TO detent?

Answer 27

5 minutes

Question 28

What 3 things need to happen in order for Mach Hold to be Active (MACH HOLD ON and Green Mach Hold in between N1 gauges)?

Answer 28

N1 or N2 must be sync’d

Aircraft Trimmed for steady level flight.

Autopilot Engaged in either Altitude Hold or Altitude Select (with altitude captured)

Question 29

Answer 29

5 C

Question 30
