Engines/Thrust Levers (Powerplant/Autothrust)

Question 1

What controls the Engines in all operating regimes?

Answer 1

FADECS (Full Authority Digital Engine Controls)

Question 2

What is the Power source for the FADEC?

Answer 2

The FADEC has its own alternator independent of the Electrical system when N2 is above 10%

If the alternator fails/engine is below 10% the FADEC is powered by the Electrical System

Question 3

What must you do if the FADEC detects a fault during an automatic Engine Start?

Answer 3

Nothing- The FADEC will discontinue the start, dry crank to clear fuel from the engine, and attempt a restart (If Warranted) automatically.

Question 4

How many igniters fire during an automatic ground engine start?

Answer 4

One, with the other serving as a back up.

The FADEC automatically alternates between igniter A and B at each Start sequence

Question 5

How many igniters fire during a Manual or In-Flight start attempt?

Answer 5

Both A and B together

Question 6

How do you arm Autothrust on the ground?

Answer 6

Have at least one FD on

Place thrust levers in the TOGA or FLEX detent (Flex temp must be entered in MCDU)

Question 7

What is the active range of the A/THR?

Answer 7

2 Engines- Just above IDLE to the CL detent

1 Engine- Just above IDLE to the MCT detent

Question 8

What determines the maximum thrust the A/THR can command?

Answer 8

the Thrust Lever Angle

Question 9

What are 3 ways to disconnect the A/THR?

Answer 9

A/THR Pushbutton
Instinctive Pushbutton (old TOGA button)
Moving thrust levers to IDLE

Question 10

What is the proper method of disconnecting the A/THR?

Answer 10

Set TLA to the current EPR and press the instinctive pushbutton

Question 11

How would the A/THR be disconnected for the remainder of the flight?

Answer 11

Press and hold the instinctive pushbutton for 15 seconds.

A/THR then cannot be reengaged and ALPHA FLOOR is also lost.

Question 12

What happens to thrust and what would you see on the FMA if Alpha Floor is triggered?

Answer 12

Thrust will go to TOGA

A.FLOOR will annunciate on the FMA

Question 13

When does the aircraft leave A.FLOOR and what will the FMA change to?

Answer 13

Leaves A.FLOOR upon reaching a lower AoA

FMA will then show TOGA LK

Question 14

How do you get out of TOGA LOCK?

Answer 14

Press the instinctive disconnect pushbuttons an return thrust levers to the CL detent if not already there.
You may then reengage the A/THR

Question 15

When will ALPHA FLOOR trigger?

Answer 15

When the aircraft reaches a high AoA

Question 16

When would Thrust Lock occur?

Answer 16

A/THR disconnects due to a failure or

A/THR pushbutton on the FCU is pressed with the Thrust Levers in the CL detent

Question 17

How is A/THR Normally armed?

Answer 17

By advancing the thrust levers to the FLX or TOGA detent.

Question 18

What are the normal FMA indications on FLEX takeoff roll when departing a RWY w/ a localizer?

Answer 18

MAN FLX, SRS, RWY, A/THR (BLUE)

Question 19

What are the normal FMA indications on a TOGA takeoff roll when departing a RWY w/out a localizer?

Answer 19

MAN TOGA, SRS, , A/THR (BLUE)

Question 20

What would be the FMA indications be on T/O roll if the A/THR didn’t arm on a rwy w/ a localizer? Should the T/O be rejected?

Answer 20

SRS, RWY
Continuing is a safe option but at acceleration altitude the crew will have to manually engage the A/THR after placing the levers in the CL detent

Question 21

How should the A/THR be turned off?

Answer 21

Match the blue TLA indicators on the E/WD to the present thrust setting and then press the Instinctive pushbuttons OR
Move the Thrust Levers to IDLE

Question 22

What should you do to get out of THRUST LOCK?

Answer 22

Move the thrust levers out of the CL detent

Question 23

What controls the engine LP fuel valves?

Answer 23

Engine Master Switches

Engine Fire Pushbutton

Question 24

What does a Fault Light on the ENG Panel indicate?

Answer 24

H- HP Fuel SOV is not in its commanded position
A- Automatic start abort
T- Thrust Control Malfunction

Question 25

When does continuous ignition automatically operate for the PW 1100G?

Answer 25

F- Engine Flameout Detected
I- Ignition Delay during start
S- Surge Detected
T- Thrust Control Malfunction Detected

Question 26

When does continuous ignition automatically operate for the IAE V2500?

Answer 26

M- Master switch cycled ON-OFF-ON
E- Engine A/ICE PB on
E- EIU Data Failed (IGN/Bleed Config Data)

F- FLEX T/O thrust selected (EPR Mode)
A- Approach Idle Selected
S- Sub Idle or Surge Inflight
T- T/O thrust selected (EPR or N1 Mode)

Question 27

What is the required engine warm up time?

Answer 27

shutdown <2 hours- 3 min

shutdown 2+ hours- 5 min

Question 28

What is the required engine cool down time?

Answer 28

IAE V2500 REV IDLE- 0 MIN
IAE V2500 >REV IDLE- 3 MIN
PW1100G- minimum 3 MIN, 5 recommended

Question 29

What does the cooling indication mean on the E/WD for NEOs?

Answer 29

Dry cranking is required before engine start, timer indicates approximate time of cooling cycle

Question 30

What is the Engine run-up procedure if there is icing conditions on the ground?

Answer 30

IAE V2500- 50% N1 Every 15 Min

PW1100G- 60% N1 Every 30 Min

Question 31

If during engine start the ground crew reports a fuel leak from the engine, what should you do?

Answer 31

IAE V2500- Continue running the engine for 5 min, if the leak disappears you may continue the flight
PW1100G- Abort the engine start and call MX

Question 32

When is approach idle triggered?

Answer 32

V2500- In flight, flaps out of 0
