Q

Will the autothrottles operate if you don’t push TO/GA for takeoff by 50 knots? If not, when will they operate in that case?

A
  • No

* Reaching 400 feet. (autothrottles inhibited until 400 feet)

23
Q

How can you disarm VNAV, LNAV, LOC, and APP modes when armed?

A

Push the mode switch a second time

24
Q

Which PFD annunciation is associated with a fail operational automatic landing, and which one is associated with a fail passive automatic landing?

A
  • LAND 3 for fail operational

* LAND 2 for fail passive

25
Q

Which pitch mode does not provide autothrottle speed protection?

A

V/S (Vertical Speed)

26
Q

When does LNAV activate when armed?

A
  • Above 50 feet and in position to turn onto the active route leg.
  • In flight, when within 2 ½ miles of the active leg.
27
Q

When does the ROLLOUT mode activate?

A

Below 5 feet

28
Q

What controls are used by the AFDS to steer the airplane on the localizer centerline after touchdown?

A

Rudder and nosewheel steering

29
Q

What initial pitch attitude is commanded by the flight director when the flight director is turned on, while on the ground?

A

8 degrees nose up

30
Q

In flight, when is TO/GA armed?

A
  • Flaps out of up, or

* Glideslope captured

31
Q

If a VNAV descent is initiated prior to top of descent (T/D), what is the pitch mode?

A

VNAV SPD

32
Q

Describe the condition that would cause VNAV ALT to display as the pitch mode.

A

A conflict occurs between the VNAV profile and MCP altitude.

33
Q

When does the FLARE mode activate during autoland?

A

Between 60 and 40 feet RA.

34
Q

When do the autopilots start the flare maneuver?

A

Approximately 50 feet radio altitude

35
Q

When do the autothrottles retard to idle during autoland?

A

At 25 feet radio altitude

36
Q

When does the FLARE annunciation no longer display?

A
  • At touchdown

* Nosewheel smoothly lowers to the runway.

37
Q

During autoland, what action disconnects the autothrottles?

A

A reverse thrust lever is raised to reverse idle.

38
Q

What conditions would cause the autothrottles to disconnect and subsequently cannot be re-connected?

A
  • Both FMCs fail

* Two or more engines are shut down.

39
Q

Can the autothrottles be reactivated if the FMC Master switch is switched?

A

Yes

40
Q

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

A

THR REF

41
Q

When does the autothrottle annunciation change to HOLD during takeoff?

A

65 kts

42
Q

When is barometric altitude recorded by the FMC during takeoff?

A

100 kts

43
Q

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

A

Ground track

44
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.

45
Q

At acceleration 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.

46
Q

When is TO/GA mode terminated after takeoff?

A
  • By selecting any other pitch and roll mode, or

* By activation of LNAV/VNAV modes.

47
Q

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

A

When LAND 2 or LAND 3 annunciated.

48
Q

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

A

500 feet and 200 feet, depending on crab angle.

49
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 a 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.
50
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.

51
Q

How does the automatic flight control system provide stall protection?

A

Prevents speed reduction below the minimum maneuvering speed.

52
Q

Describe flight envelope speed protection.

A
  • Overspeed protection prevents exceeding the maximum operating,
  • Gear extended, or
  • Flap placard speeds.
53
Q

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

A

5 kts

54
Q

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

A
  • V/S pitch mode

* Engine failure above maximum engine-out altitude.
