Engine

Question 1

What does the ENG MASTER switch do?

Answer 1

Controls fuel flow and FADEC power; opens engine fuel valve when ON

Question 2

What does the ENG MODE selector do?

Answer 2

Controls ignition and FADEC mode: NORM, IGN/START, CRANK

Question 3

What does CRANK mode do?

Answer 3

Drives the engine starter without fuel or ignition — used for dry motor or clearing fuel

Question 4

What is the difference between IGN/START and NORM?

Answer 4

IGN/START: continuous ignition and start valve opens; NORM: ignition automatic and based on FADEC logic

Question 5

What does a FAULT light in the ENG MASTER switch mean?

Answer 5

A malfunction (e.g. valve disagreement or fault in engine control)

Question 6

What does the amber FAULT light in the ENG MODE selector mean during start?

Answer 6

Start fault detected — engine auto shutdown initiated

Question 7

What happens when you turn the ENG MASTER switch OFF?

Answer 7

Engine fuel shutoff valve closes, FADEC loses power after cooldown, engine shuts down

Question 8

Are there engine indications on ECAM if electrical power is lost?

Answer 8

Yes — on batteries, essential engine parameters (N1, EGT, fuel flow) are still shown

Question 9

How is engine ignition controlled during a normal automatic start?

Answer 9

FADEC activates igniters as needed

Question 10

Which igniter is used for engine start?

Answer 10

Either A or B — alternates each flight, or both used depending on conditions

Question 11

What does the FADEC do?

Answer 11

Controls engine parameters, start sequencing, ignition, and fuel metering based on thrust lever input

Question 12

Can FADEC start the engine without crew input?

Answer 12

No — crew must move ENG MASTER switch ON
