Auto Flight Flashcards
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
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 FMA means?
- 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?
- N1
- SPD
- VNAV
- FLCH
- GA
What are the exclusive modes of A/T?
- N1
- SPD
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
What is the default mode of A/T?
- SPD
What mode does the A/T system not reposition the thrust levers?
- THROTTLE HOLD
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 2.5 nm
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
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 CLB and then MACH to IAS in a descent?
- Mach .80 and 300kts
