Q

How can the LOC mode be disengaged after localizer capture?

A

• selecting a roll mode other than LNAV
• pushing a TO/GA switch
• disengaging the autopilot and turning both flight director switches off, or • pushing the localizer switch a second time above 1,500 feet radio altitude
(reverts to the default roll mode)

21
Q

How can APP mode be disengaged in the following situations:

d. LOC and G/S captured.

A

a. Push APP a second time or select another pitch or roll mode.
b. Select another roll mode.
c. Select another pitch mode.
d. Engage TO/GA mode or disengage A/P and turn off both FDs. (Above
1500ft, press APP switch a second time).

22
Q

What does a green box around a mode mean?

A
  1. The mode has changed within the last 10 seconds.
23
Q

What is the effect of:

a. First push of A/P disengage switch?
b. Second push?What does a green box around a mode mean?

A

a. A/Ps disengage with all visual and aural warnings. b. Resets visual and aural warnings.

24
Q
  1. How can the Master Caution lights and EICAS message be reset after a manual A/T disconnect?
A

Second push of disconnect switch.

25
Q
  1. Briefly describe the A/T HOLD mode.
A
  1. A/T servo inhibited. Levers remain in last position but can be manually positioned.
26
Q
  1. The autothrottle can be operated without using the autopilot or F/D. What A/T modes are available in this situation?
A
  1. SPD, mode.
27
Q

a. If the autothrottle is disconnected but still armed, what happens if airspeed approaches stick shaker activation speed?\
b. What speed does the autothrottle command?
c. When is this function not available?
d. What could happen during a VNAV SPD descent?

A

a. The auto throttle engages in SPD or THR REF mode.
b. Minimum maneuvering speed (top of the amber band) or the speed set in
the MCP speed window, whichever is greater.
c. When the pitch mode is FLCH or TOGA, or the airplane is below 400
feet after takeoff, or below 100 feet radio altitude on approach.
d. The autothrottle may activate in HOLD mode and does not support stall
protection.

28
Q

What do the FD bars command at: a. Pre-flight?

b. Lift-off

A

a. 8 degrees up and wings level. b. V2 + 15 and ground track.

29
Q
  1. Which A/T mode will be engaged when a TO/GA switch is pushed on the ground?
A
  1. THR REF
30
Q
  1. When does HOLD mode engage during take-off?
A

80kts

31
Q
  1. After lift-off, what are the F/D pitch commands during with an engine failure?
A
  • If engine failure after lift-off occurs, the pitch command target speed is V2,
  • if below V2; existing speed if between V2 and V2 +15;
  • and V2 + 15 if above V2 + 15.
32
Q
  1. How can the TO/GA mode be terminated after take-off?
A

By selecting another pitch and roll mode or by activation of LNAV/VNAV
modes.
4. AUTO

33
Q
  1. When are changes in autoland status annunciations (e.g. LAND 3, LAND 2) inhibited?
A

Below 200 feet, other than transition to NO AUTOLAND status, are inhibited.

34
Q
  1. On approach, with LAND 2 or LAND 3 annunciated, which EICAS Caution messages are not inhibited below 200RA?
A
  1. AUTOPILOT, AUTOTHROTTLE DISCONNECT, SPEEDBRAKE EXTENDED.
35
Q

What roll and pitch annunciations would the PFD display when the APP mode had been selected prior to capture of LOC or G/S?

A
  1. Existing roll & pitch modes in green; LOC & G/S in white.
36
Q
  1. What is the maximum localiser intercept angle?
A

120°

37
Q
  1. What determines the LOC capture point?

  1. What are the indications of LOC capture?
A
  1. Green LOC FMA mode.
39
Q
  1. Is G/S capture dependent on LOC intercept angle?
A
  1. Yes. Intercept track angle must be within 80° of localizer course.
40
Q
  1. When is the ALIGN manoeuvre commenced?
A
  • 500ft AGL for crab angles > 10 degrees
  • Initially 500ft AGL and again at 200ft for crab angles between 5 degrees and 10 degrees
  • 200ft AGL for crab angles <5 degrees
41
Q
  1. a. When are FLARE and ROLLOUT armed? b. When are FLARE and ROLLOUT engaged?
A

a. When LAND 3 or LAND 2 is annunciated on PFD.

b. FLARE 50 feet, ROLLOUT less than 2 feet.

42
Q
  1. What is the A/T mode annunciation at 25ft RA?
A

IDLE

43
Q
  1. When does the FLARE mode annunciation disappear?
A

Touchdown

44
Q
  1. Until what point does ROLLOUT mode provide guidance?
A
