ADR 1 (2) (3) pb (momentary action)
(ADIR Panel)

- OFF
- FAULT Light

OFF:
Air data output disconnected.

FAULT:
This amber light comes on with an ECAM caution, if a fault is detected in the air data reference part.

33

What are the GPWS modes?

- Mode 1: Excessive descent rate ("Sink Rate")

- Mode 2: Excessive terrain closure ("Terrain, Terrain")

- Mode 3: Altitude loss after takeoff ("Don't Sink")

- Mode 4: Unsafe terrain clearance ("Too Low Flaps", "Too Low Gear")

- Mode 5: Excessive GS deviation ("Glideslope")

34

What are the functions of the Flight Management Guidance Computers?

- Flight Guidance

- Flight Management

35

What are the 2 modes of flight guidance?

- Managed Guidance

- Selected Guidance

36

What is the Managed mode of flight guidance used for?

Long-term lateral, vertical and speed profiles as determined by the FMGS

37

What is the Selected mode of flight guidance used for?

Temporary lateral, vertical and speed commands as selected with the FCU

38

Does Selected or Managed Guidance have priority?

Selected Guidance has priority

39

What do dashes in the FCU display windows along with the adjacent white dot indicate?

FMGS Managed Guidance is in use

40

How is Selected Guidance engage?

Pull the appropriate selector knob

41

What are the main components of the FMGS?

- 2 FMGCs

- 2 MCDUs

- 1 FCU

- 2 FACs

42

What type of database is periodically updated in the FMGS?

Navigation database

43

What is the normal operational mode of the FMGS?

Dual mode, with one FMGS as master and the other FMGS as slave

44

How does autopilot selection influence master FMGS logic?

- If one autopilot is engaged, the respective FMGS is master

- If both autopilots are engaged, FMGS 1 will be the master

45

If an amber SELECT OFFSIDE RNG/MODE message is displayed on the ND what action should the crew take?

An FMGS has failed and both NDs must be set to the same mode and range (Single Mode)

46

What is the function of the Flight Control Unit?

- Permits short term interface between the pilot and FMGS

- Allows temporary modification of any flight parameter (HDG, SPD, ALT, V/S)

- Used to select operations modes of the autopilots, flight directors, and A/THR system

47

The LDG ELEV selector in the AUTO position does what?

The pressurization system uses the FMGS data to construct an optimized pressurization schedule

48

The LDG ELEV selector in the AUTO position does what?

The pressurization system uses the FMGS data to construct an optimized pressurization schedule

49

The LDG ELEV selector in the AUTO position does what?

The pressurization system uses the FMGS data to construct an optimized pressurization schedule

50

What are the 3 modes of FMGC operation?

- Independent (MCDU scratchpad displays - INDEPENDENT OPERATION)

- Single (ND displays - SELECT OFFSIDE RNG/MODE)

- Dual (Normal)

51

What input does each FMGC use for position determination?

A hybrid IRS/GPS position

52

If the NAV key is selected on either RMP, can the FMGC still auto tun navaids?

- NO. RMP now control the VOR/ILS receivers

- NAV key on RMP 3 has no effect

- Normal radio communication is still available

53

What is the difference between the magenta and blue target airspeeds?

- Magenta: Managed speed computed by the FMGC

- Blue: Selected speed on the FCU

54

What does it mean when the altitude digits change from green to amber?

The aircraft has descended below the MDA/DH entered into the FMGC

55

From what source does the pressurization system obtain landing elevation?

FMGC database

56

Can the crew modify data in the navigation database?

The crew has limited ability to create pilot stored navigational data

57

How do you determine the validity of the navigation database?

On the Aircraft Status page

58

What is the difference between the large and small fonts utilized in the MCDU?

- Large: Pilot entries and modifiable data

- Small: Default/computed non-modifiable data

59

What do amber box prompts on the MCDU indicate?

An entry is mandatory

60

After you input the destination and ILS information into the MCDU, what do you check for?

- After the LS pushbutton is pressed - green light

- ILS frequency and course on PFD

- ILS identifier once identified

- LOC and GS scales displayed on PFD

61

How do you normally enter Present Position into the IR?

-Insert the Lat/Long on the MCDU INIT page

-Then press Align IRS
