Q

LAND3, will a single fault prevent A/P system from making an automatic landing?

A
  • NO
  • With a LAND2, the level of redundancy is such that a single fault cannot cause a significant deviation from the flight path.

Q

When does LNAV activate when armed?

A
  • Above 50’ and in position to capture active leg

- In flight, within 2.5 miles of active leg

25
Q

When does the ROLLOUT mode activate?

A

Below 5’

26
Q

What initial pitch is commanded by FD when turned on, on the ground?

A

8 degrees nose UP

27
Q

In flight, when is TO/GA armed?

A
  • Flaps out of UP

- GS captured

28
Q

If VNAV descent is initiated prior to TOD, what pitch mode is used?

A

VNAV SPD

29
Q

When does VNAV ALT display?

A

A conflict occurs between the VNAV profile and MCP altitude

30
Q

When does the FLARE mode activate?

A

Between 60 and 40’

31
Q

When do APs start the flare maneuver?

A

Approx 50’

32
Q

When do A/Ts retard to idle during AUTOLAND?

A

25’ RA

33
Q

When does FLARE deactivate?

A
  • At touchdown

- Nosewheel will smoothly lower to runway

34
Q

During AUTOLAND, what action disconnects the A/Ts?

A

Reverse thrust lever is raised to reverse idle

35
Q

What conditions would cause the A/Ts to disconnect and subsequently cannot be re-connected?

A
  • Dual FMC failure

- Two or more ENG out

36
Q

Can the A/Ts be reconnected if the FMC Master switch is switched?

A

Yes

37
Q

During takeoff, when TO/GA is selected, what A/T mode is active?

A

THR REF

38
Q

When does the A/T annunciation change to HOLD during takeoff?

A

65 knots

39
Q

When is barometric altitude recorded by the FMC during takeoff?

A

100 knots

40
Q

At liftoff, with TO/GA as the roll mode, what roll command is maintained?

A

Ground track

41
Q

If an engine failure occurs on the ground, what is the pitch command target speed at liftoff?

A

V2, or airspeed at liftoff, whichever is greater

42
Q

At accel height, what speed commands are established by pitch as the flaps are retracted?

A

5 knots below the placard speed of the commanded flap position

43
Q

When is TO/GA mode terminated after takeoff?

A

Be selection of any other pitch and roll mode or activation of LNAV/VNAV

44
Q

When does the A/P control the rudder during multi A/P approaches?

A

When LAND2 or LAND3 annunciated

45
Q

At what two altitudes will runway alignment occur during multi A/P approaches during crosswinds, with all engines?

A

500’ and 200’, depending on crab angle

46
Q

How does the A/P maintain runway alignment if an engine failure occurs prior to the approach, during multi A/P approaches? If during approach?

A
  • AFDS introduces sideslip at 1300’ AGL
  • Establishes a wings level configuration
  • If an engine fails during the approach, wings level is established when the engine failure is detected
47
Q

What pitch is commanded by the AFDS when TO/GA is pushed in a windshear recovery on approach?

A

15 degrees pitch-up or slightly below the pitch limit, whichever is lower

48
Q

How does the automatic flight control system provide stall protection?

A

Prevents speed reduction below the minimum maneuvering speed

49
Q

Describe flight envelope speed protection?

A
  • Overspeed protection prevents exceeding the max operating GEAR EXTENDED or FLAP PLACARD SPEEDS
50
Q

What speed protection margin is used by the AFDS in max operating, flap placard speed, and gear extended speeds?

A

5 knots

51
Q

What two conditions prevent the AFDS and autothrottle from providing speed protection?

A
  • V/S pitch mode

- Engine failure above max engine-out altitude

52
Q

What conditions will result in total loss of A/Ts?

A
  • Loss of 2 ENG

- Dual FMC Failure

53
Q

With dual FMC failure, what basic capabilities are available with the CDUs?

A
  • Lateral navigation computations

- Tuning of NAV radios

54
Q

What is the purpose of the EIUs?

A

To provide A/C systems to the 6 display screens.

- PFDs, NDs, both EICAS

55
Q

What FMS-CDU pages are available with a dual FMC failure?

A
  • NAV LEGS
  • NAV PROG
  • NAV NAVRAD
56
Q

When do the A/Ts disconnect during an RTO?

A

When any TR is brought to idle.

57
Q

What modes are A/T avail in without pushing THR button on MCP?

A

VNAV and FLCH SPD

58
Q

What modes will enable A/T when THR button is pressed?

A

Rule of 3:

  • V/S
  • G/S
  • ALT

Any other mode will require cycling of the A/T switch on the MCP.
