Flashcards in Auto Flight Deck (28):
1

How can the LLZ and GS modes be deactivated after LOC & GS capture?

  • Disconnecting A/P & A/T and turning both F/D's Off or:
  • Selecting GA mode

2

When will the F/D command bars display when F/D not on?

  • When GA switch is pushed and airspeed is ABV 80kts with the flaps not retracted
  • Can be removed by cycling the switch
  • Will command GA Thrust limit

3

At what altitude can the Autoland status annunciators not change?

  • BLW 200ft except to indicate a NO AUTOLND condition

4

SPD in A/T FMA means?

  • A/T controlling thrust to maintain SPD in window or: 
  • If VNAV engaged, the SPD programmed by the FMC

5

What are the 5 modes of A/T?

  • N1
  • SPD
  • VNAV
  • FLCH
  • GA

6

What are the exclusive modes of A/T?

  • N1
  • SPD

7

What will be indicated on FMA when A/P is set to CMD after Take off with FD off?

Bank angle less than 5 degrees:

  • V/S and HDG HOLD

Bank angle greater than 5 degrees:

  • V/S and ATT
  • When greater than 30 degrees AFDS returns to 30 degrees

8

What is the default mode of A/T?

  • SPD

9

What mode does the A/T system not reposition the thrust levers?

  • THROTTLE HOLD

10

What happens with A/T in a GA if A/P and F/D's are off?

  • Controls to go-around reference thrust subject to flap and Vmo speeds

11

When does LNAV immediately activate when intercepting a route?

  • Within 2.5 nm

12

When does G/A mode ARM and how is it displayed?

  • Flaps out of up or Glideslope capture
  • No real annunciation, reference thrust limit just changes to G/A

13

When does ROLLOUT arm and engage?

  • BLW 1500ft armed displays and it engages below 5ft

14

When does the AFDS capture the LLZ?

  • Within 120' of LLZ course

15

When does SPD change from IAS to MACH in a CLB and then MACH to IAS in a descent?

  • Mach .80 and 300kts

16

What are the 3 methods to return from THR-HOLD to FLCH mode

  • A/T is set off then ARM
  • Select other pitch mode then re-select FLCH
  • Thrust levers advance manually, set to reference bug

17

When does the ALT light illuminate on the Altimeter?

  • Between 300 and 900ft
  • White light displays on top right of Altimeter
  • ALT ALERT- Amber light displays on the main panel next to standby AItimeter

18

What will display on the FMA for FLCH in a CLB or DESCENT also in ALT HOLD?

CLB/DESCENT

  • FLCH , SPD

ALT HOLD

  • SPD, ALT HOLD

19

In VNAV what happens when A/C levels out in CRZ

  • TMSP changes reference thrust to CRZ

20

If SPD is set in the A/T window what controls A/C SPD?

  • Thrust (power control)

21

In a descent what will be indicated if done in FLCH?

  • FLCH then THR-HOLD / SPD

22

What is indicated in a VNAV CLB?

  • N1 / VNAV SPD

23

What happens in a level off in VNAV

  • SPD (commanded by FMS) / VNAVPTH

24

When will the VOR/DME SW become AUTO?

  • Only when HSI mode selector is set to MAP or PLAN

25

When does the VOR/DME always indicate manual?

  • Always at VOR, ILS mode

26

When is HDG up indicated on HSI and when is TRACK up indicated?

  • HDG UP = VOR, ILS mode
  • TRACK UP = MAP, PLAN mode

27

When does RWY align mode begin?

  • 500ft RA with LAND 2/3 annunciated

28

What slip will the autopilot initiate during RWY align mode?

  • A maximum bank angle of 2 degrees when the crab angle exceeds 5 degrees
