Q

What is the function of the FCU?

A

Permits short term interface between the pilot and FMGS
Allows temporary modification of any flight parameter (HDG, SPD, ALT, V/S)

Q

How is selected guidance engaged?

A

Pull the appropriate selector knob

20
Q

How do you confirm all AP, FD and A/THR inputs?

A

Read the FMA

21
Q

Will the FCU altitude window ever display dashes?

A

No. Pilot selected altitude will always be displayed

22
Q

What does each column mean on the PFD?

A

A/THR | VERTICAL | LATERAL | APPROACH CAPABILITY, DH/MDA | AP, FD, A/THR STATUS

23
Q

How is the crew made aware of mode changes on the FMA?

A

White box is temporarily displayed around the new indication

24
Q

How are armed modes displayed on the FMA?

A

Blue- Armed
Magenta- Armed because of a constraint
Green- Engaged

25
Q

When is the sidestick position indication icon (White cross) displayed?

A

First engine is started
Disappears at liftoff

26
Q

What would the large red arrows indicate?

A

Pitch attitude of more than 30 degrees

27
Q

What is the meaning of USE MANUAL PITCH TRIM?

A

Direct Law

28
Q

What is the meaning of MAN PITCH TRIM ONLY?

A

Mechanical Backup

29
Q

What are the pitch and roll angle limits indicated by the green = signs?

A

Pitch: +30 degrees up/ -15 degrees down
Roll: +/- 67 degrees

30
Q

How can you determine you are in ALTERNATE LAW?

A

Amber X’s replace the green = at the pitch and bank limits
Only VLS and VSW are displayed on the airspeed scale

31
Q

When would the slideslip index change from yellow to blue?

A

Engine fire/failure during takeoff/go around. (Blue is now BETA TARGET)

32
Q

What does yellow speed trend line on the airspeed scale indicate?

A

Speed the aircraft will reach in 10 seconds if acceleration/deceleration remains the same

33
Q

What is the difference between the magenta and blue airspeed targets?

A

Magenta- Managed speed
Blue- Selected speed

34
Q

What does Vmax represent and how is it displayed?

A

Lowest of Vmo/Mmo, Vle, or Vfe
Bottom of a red and black strip along the airspeed scale

35
Q

What is Vls?

A

Represents the lowest selectable speed providing an appropriate margin to stall speed
Corresponds to 1.13 VS during takeoff
Corresponds to 1.23 VS after retraction of 1 step of flaps
Corresponds to 1.28 VS in clean config
Above 20,000ft, Vls is corrected for Mach effect to maintain a buffet margin of 0.2g
In approach mode it is equivalent to Vref
Increases with speed brake extension

36
Q

What is green dot speed?

A

Engine out operating speed in clean config
Appears when the aircraft is in the clean config
Corresponds to best lift/drag ratio

37
Q

What is ground speed mini?

A

Based on a calculated groundspeed at the runway
Protects against actual groundspeed dropping below this calculated groundspeed

38
Q

What does it mean when you see magenta target airspeed triangle above the VAPP on approach?

A

Ground speed mini increased speed due to a higher headwind component at your present location than what was calculated at the runway

39
Q

Is ground speed mini protection available in selected speed?

A

No

40
Q

What are 3 ways to disconnect the A/THR?

A

Disconnect buttons
Thrust levers to idle
A/THR PB

41
Q

How do you disconnect the A/THR for the remainder of the flight?

A

Press and hold the instinctive disconnect pushbuttons for 15 seconds

42
Q

What would you lose if you held down the instinctive disconnect pushbuttons for more than 15 seconds?

A

Alpha Floor protection

43
Q

What happens to thrust and what annunciates on the FMA when you reach Alpha Floor?

A

Thrust- TOGA
FMA- A.FLOOR

44
Q

What occurs during alpha floor protection after speed increases above Vls?

A

FMA Changes to TOGA LK

45
Q

How do you regain normal A/THR when in TOGA LK?

A
  1. Move thrust levers to TOGA
  2. Press the Instinctive Disconnect button
  3. Return Thrust levers to CL detent
  4. Push the A/THR PB to engage A/THR
46
Q

When is Alpha Floor Protection active?

A

Lift off - 100ft RA on approach

47
Q

When would thrust lock occur?

A

Thrust levers in the CL detent and A/THR on the FCU is pushed OR A/THR disconnects due to a failure
