Flashcards in Engines Deck (45):
1

A320 and A319 Engines are considered?

- D-rated variants of the V2500 engine

2

How much thrust is produced on A319?

- V2524-A5 produces 24,000 pounds of thrust

3

How much thrust is produced on A320?

- V2527-A5 produces 27,000 pounds of thrust

4

How much thrust is produced on A321?

- V2530-A5 produces 32,500 pounds of thrust

5

How much thrust is produced on A320 NEO?

- PW1100G-JM produces 27,000 pounds of thrust

6

What is on the accessory gear box on the engine?

- Fuel pump
- Oil pump
- Alternator (automatically powers when engine reaches 10% N2)

7

How many side strake's on A320, A321, A319?

- A320 only has 1 inner strake
- A319, A321 have 2 total, 1 each side of the engine

8

What happens if one strake is missing?

- A performance penalties applys

9

How is each engines FADEC (full authority digital engine control) cooled?

- FADEC is cooled by ambient air

10

What does FADEC control?

- Fuel flow
- Thrust reverse
- Ignition control
- Protects exceeding N1, N2 and EPR limits
- Protects from EGT limits (ground only)
- Protects starter engagement time and re-engagemnt
- Computation of fuel used
- Thrust limits
- Thrust penalties for use of air conditioning + Ice protection
- Acceleration + deceleration schedules
- Idle settings
- Providing engine information

11

How can engines start?

- Manually or Automatically

12

What does FADEC control on auto engine starts on the ground?

- FACEC has abort authority
- EGT
- Controls starter sequence
- Starter valve + HP fuel valve
- Fuel flow + Ignition
- N1+N2 monitoring
- Control starter aborts

13

What does FADEC do on manual starts?

FADEC monitors engine starts and provides warnings but does not have abort authority

14

What are three idle settings?

- Modulated idle (on ground)
- Approach idle (higher idle for go around)
- Reverse idle (slightly higher)

15

What is the normal mode for controlling thrust?

- EPR is the normal way for controlling thrust

16

What happens if EPR is not available for thrust control?

- FADEC will then use N1 mode (can be manually selected)

17

Thrust is control by FADEC looking at?

- Angle of thrust levers

18

How long is TOGA (max thrust) limited to?

- 5 minutes

19

When is MCT used?

- Single engine

20

When must you be out of max revers?

- Out of Max reverse at 70 knots

21

What are the 2 modes of A/THR (auto thrust)?

- Active
- Armed

22

When is A/THR automatically armed?

- During takeoff when trust levers are in TOGA or FLEX

23

What is A/THR active range?

- From just above idle to climb

24

What will you see in the EPR gauge on A320 and not on A319,A321?

- Green AVAIL in green in EPR gauge indicating a successful engine start.

25

Where is thrust limit displayed?

- Displayed right of EPR gauge

26

When will you get a Amber oil pressure warning?

- Oil pressure dropping below 80 PSI

27

When will you get a Red oil pressure warning?

- Oil pressure drops below 60 PSI

28

When will you get a Amber oil temperature warning?

- Oil temperature above 155 degrees for more than 5 minutes or above 165 degrees

29

When will vibration indication puls green?

- Vibration above 5 units

30

What does it mean when you have amber XX on engine gauges?

- FADEC is shut down.
- If engines are not started with 5 min of AC power established FADEC auto shuts down

31

When will FADEC be re-powered before engine start?

- When IGN/START switch is selected

32

After IGN/START selected what happens if after 30 seconds and engine is not started?

- The Doors/Oxygen page will replace Engine page automatically

33

Which engine is started first on the Airbus?

- ENG 1 (if single engine taxi Y pump ON for brakes)

34

When is the used fuel reset?

- When engine start is accomplished

35

When is ignition and fuel flow started when starting?

- Approximately 30 seconds

36

When does the start valve and ignition turn off?

- When N2 reaches 43-48%

37

When does the gray box go away?

- N2 reaches 58% (green AVAIL light A320 only)

38

Memory item for stabilized engine start 2,4,6,8,10?

- 20% N1
- 400 EGT
- 60% N2
- 800 Fuel Flow
- 1.0 EPR Just over

39

When is manual engine start done?

- When low duct pressure (min 15% N2)

40

How do you turn on both Igniters with engines running?

- Move ENG start switch to IGN/START

41

How can you shut down an engine if the ENG switch will not work?

- Push the ENG FIRE push button
- Will take approximately 40 seconds to shut down do to fuel in the line.

42

Will FADEC abort a start and try to re start and engine?

- Yes (after 30 seconds dry motoring will try another start)

43

When do you get the amber FAULT light on the ENG BLEED pbs?

- APU bleed valve open and engine bleed valve not closed
- S Engine start with bleed valve not closed
- O verpressure downstream of the bleed valve
- L eak (low pressure)
- O verheat

44

Engine bleed valve closes?

- A PU bleed ON
- S art valve open (engine)
- O verpressure
- L Bleed leak
- O verheat

45

How do you know when you are in D rated mode?

Loss of EPR mode, must switch to N1 mode. In d rated you can over boost the engine. N1 mode is limited to inlet temperature.
