Q

When is the FMS prohibited as a sole NAV source for instrument approaches?

A

Localizer-based approaches, VOR approaches, NDB approaches

Q

How does the FD respond during climb-out when TOGA is selected during both basic and FMS-assisted go-arounds?

A

Basic: in green navigation, it holds the current heading in a wings-level mode and maintains a pitch from
10° minimum to 20° maximum changing to ALTS at the MAP altitude FMS-assisted: during an ILS/GPS approach, GA changes to FMS NAV and VNAV at 400 feet AGL
Note: Half bank is not available for use
during a missed approach

Q

What are the four purposes of the MSTR DISC pushbutton on the control wheel?

A
  1. Disconnect the AP
  2. Silence a disconnect aural
  3. Interrupt pitch trim while held
  4. Inhibit the stick pusher while held (non-EASA aircraft)

Q

What is the FD “pitch target box” command for a normal takeoff?

A

Initially set to 17.5º and can move between 11.5º to 20º to hold the selected speed

20
Q

How is the take-off mode cleared?

A

Engaging the AP, selecting another vertical mode, pressing the TCS button

21
Q

What will cause automatic disengagement of the AP?

A

Unusual attitude, stall warning activation, activation of WS avoidance (2 sec delay)

22
Q

What does a flashing/steady amber LIM in the AT mode annunciation indicate?

A

Flashing LIM: an airspeed target deviation is sensed

Steady LIM: structure limit, minimum speed limit, or a maximum power limit

23
Q

What occurs when the EDM is manually selected above FL250?

A

FD will command a descent to 15,000ft, a left turn 90º, AT will target VMO-10kts or MMO-0.02 until 15,000ft, then 250kts

24
Q

What is required for an auto Nav-to-Nav transfer to occur?

A

Lateral mode is FMS, aircraft has captured the desired LOC, APPR button on the FCP is selected

25
Q

What will happen in the event the master AFCS/AT fails?

A

Standby AFCS/AT automatically takes over and the FD modes will revert to basic ROLL and FPA

26
Q

When is the LOC preview mode enabled?

A

Automatically at 30nm

27
Q

What is the minimum height that the AP can be used for a non-precision APP with vertical path reference?

A

160ft AGL

28
Q

How is the A/T GA mode cleared?

A

Select another vertical mode

29
Q

When does the AFCS initially engage the yaw damper?

A

Automatically when a remote electronics unit (REU) and two sources of roll and yaw are available from the IRS

30
Q

Which parameters are used to calculate the Vate (min manoeuvring speed) value?

A

IAS, flap position, and stall data

31
Q

What is the FD “pitch target box” command during take-off after an engine failure?

A

Initially set to 13º and moves between 8º and 13º to maintain the selected speed

32
Q

How are active/armed FD and AT modes indicated on the FMA?

A

Active displays in GREEN, armed displays in WHITE

33
Q

Prior to what speed must the AT be verified engaged and take-off thrust verified set?

A

60KIAS

34
Q

Does the indicator light on the FCP indicate that the associated mode is currently active?

A

No, the pilot must confirm mode status or operation from the FMA on the PFD

35
Q

How is the AFCS 1 manually selected to AFCS 2?

A

Selecting the AFCS 1/2 switch on the RSP

36
Q

How is the EDM cancelled?

A

Disengage the AP

37
Q

What happens to the AP/FD modes during a WS warning?

A

Escape guidance is provided via the guidance cue, AT and vertical modes indicate WSHR, thrust setting is TO EPR, AP disconnects after a 2-sec delay

38
Q

What are the three conditions to automatically activate the EDM?

A

AP engaged, altitude above 25,000ft, cabin alt exceeded 14,500ft

39
Q

What is the bank angle for half bank?

A

17º

40
Q

What is the min height that the AP can be used during a CAT I or CAT II precision APP (ILS)?

A

80ft AGL

41
Q

When is the “pitch target box” removed?

A

Removed upon selection of any vertical mode

42
Q

When does the AT transition to the retard mode?

A

Aircraft in landing config, RADALT of 50ft AGL

43
Q

How is the master AFCS identified?

A

FCP indicator lights adjacent to the YD and AP buttons

44
Q

What is the min height that the AP can be used during a non-precision APP with no vertical guidance?

A

400ft AGL

45
Q

What is the purpose of the TCS button?

A

Momentarily overrides the AP and sync FPA, speed or VS value

46
Q

What does the horizontal yellow line on the airspeed tape indicate?

A

Min manoeuvring speed (Vate)

47
Q

What will cause manual disengagement of the AP?

A

Pressing the AP button, pressing either MSTR DISC
pushbutton, manual trim activation, pressing the YD button on the FCP, physical override of the AP servos (not recommended)
