the engine automatically

during start?

the engine for a stuck fan?

What is the memory item

for a dual engine failure

in low altitude?

a) Check fuel tanks/quantity

b) Both fuel boost on

c) Throttles cutoff

Engine start button

 remains illuminated.

What is the problem?

Start relay stuck

Press the disengage switch

How long can you motor

the engine with APU

or GPU on?

15 seconds

To maintain ITT below start limit, what should you check

prior to engine start?

Engine ITT below 500C

At what battery amps

should you start the

second engine?

100 amps or less

How long can you be at

T/O power on 2 engines?

5 minutes

How long can you be at

T/O power single engine?

10 minutes

When do you select

ignition off?

During dry motoring.

 otherwise fadec function

What does IGN mean?

Power has reached one

of the two exciter boxes

On what bus is the ignition?

Emer bus

Why should the throttles be

in cutoff for 30 seconds,prior to shutdown electrical power?

To allow fadec data to be

downloaded to the ECU

How is the oil on the EICAS measured?

Transducer

How is the oil on the CAS system measured?

Pressure switch

How much thrust is

from bypass only?

75 %

What is the letter A or B

illuminated on fadec

select switch?

Controlling fadec channel

What is the purpose of a forced exhaust mixer?

Mixes cold air with hot primary air

to reduce noise

What do you check

at 44% N2?

 Start relay opens

Start switch should extinguish

What actions do you take if

the engine does not start?

a) Affected throttle cutoff

b) Disengage start switch

c) Call for engine start malfunction check-list

When does N1 usually

start rotating?

14% N2

What are some differences with FADEC

during airborne and ground start?

a) redundant channel switchover

test not performed in flight

b) fadec automatic abort logic

not active in flight

What will the FADEC do

during a flameout?

When N2 drops below 2%, fadec

will turn on ignition, unless

throttle is in cutoff position

Why do we set the throttles

to cutoff in a flameout?

a) To reset the Fadec start logic

b) To shutdown the fuel boost pumps,

thereby reducing the load on the batteries

What check-list will you

find a engine start malfunction?

1-Go to emergency/abnormal tab

2- Look under engine

3- Engine does not start (C3) or starter does not disengage (C4)

need for a windmill start?

Is the airplane level?

What is the minimum airspeed

to do a windmill restart?

200 kts

When can an engine start ITT

oscillates and why?

Happens at airport above 5000 feet

Due to fuel scheduling by the Electronic Engine Control (EEC) limiting ITT to 950C

What means oil level low L-R

and what should you do?

Fault in the system

Dry motor and check again in 5-20 minutes

What check-lists ask you

to reset the fadec?

Engine control fault

Ground idle in flight

When is engine sync available?

Throttles between idle and MCT

with landing gear up

with loss of DC or using EMER bus?

Isolation valve

Can you tell if you exceeded

an engine limitation just using

the stby instruments?

The affected numbers will flash

Although the check-list doesn't refer to it,

what would be a cause for concern

if you get a ENGINE CONTROL

FAULT message?

This message indicates that the FADEC

has detected a fault.

It is possible that it may have "disconnected" the engine thrust from the throttles, therefore giving you a unresponsive engine "stuck" at the last power setting.
