Flashcards in Auto Flight Deck (28)
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 ORSelecting GA mode
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
At what altitude can the Autoland status annunciators not change?
BLW 200ft except to indicate a NO AUTOLND condition.
SPD in A/T window
A/T controlling thrust to maintain SPD in window or if VNAV engaged, the SPD programmed by the FMC
What are the 5 modes of A/T?
What are the exclusive modes of A/T?
What will be indicated on FMD when A/P is set to CMD after Take off with FD off?
Bank angle less then 5degrees- PITCH- V/S Mode, ROLL- HDG HOLD modeBank angle greater then 5degrees- PITCH is V/S mode and ROLL is ATT modeWhen greater than 30deg AFDS returns to 30deg
What is the default mode of A/T?
What mode does the A/T system not reposition the thrust levers?
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.
When does LNAV immediately activate when intercepting a route?
Within 2 1/2nm
When does G/A mode ARM and how is it displayed?
Flaps out of up ORGlideslope captureNo real annunciation, Reference thrust limit just changes to G/A
When does ROLLOUT arm and engage?
BLW 1500ft armed displays and it engages below 5ft
When does the AFDS capture the LLZ?
Within 120' of LLZ course
When does SPD change from IAS to MACH in a CLBand then MACH to IAS in a descent?
What are the 3 methods to return from THR-HOLD to FLCH mode
A/T is set off then ARMSelect other pitch mode then re select FLCHThrust levers, advance manually, set to reference bug
When does the ALT light illuminate on the Altimeter?
Between 300-900ftWhite light displays on top right of Altimeter ALT ALERT- Amber light displays on the main panel next to standby AI
What will display in the windows for FLCH in a CLB or DESCENT also in ALT HOLD
CLB/DESCENT- A/T window- FLCH Pitch Window- SPDALT HOLD- A/T window- SPD. Pitch Window- ALT HOLD
In VNAV what happens when A/C levels out in CRZ
TMSP changes reference thrust to CRZ
If SPD is set in the A/T window what controls A/C SPD?
Thrust (power control)
In a descent what will be indicated if don in FLCH
A/T window- FLCH, THEN CHANGES TO THR-HOLDPITCH window- SPD
What is indicated in a VNAV CLB
A/T- N1PITCH- VNAV SPD
What happens in a level off in VNAV
A/T- SPD (commanded by FMS)PITCH- VNAVPTH
When will the VOR/DME SW become AUTO
Only when HSI mode selector is set to MAP or PLAN
When is the VOR/DME always set to manual
Always at VOR, ILS mode
When is HDG up indicated on HSI and when is TRACK up indicated
HDG UP- VOR, ILS modeTRACK UP- MAP, PLAN mode
When does RWY align mode begin?
