Auto Flight/ MCP Flashcards
How do you re-engage the autothrottles when the pitch mode is ALT, V/S or G/S?
Press SPD
How do you re-engage the autothrottles when the pitch mode is VNAV—or FLCH SPD, when the A/T flight mode annunciation is blank?
Cycle A/T Arm Off and On
How could you select climb thrust after takeoff or go-around?
Thrust switch
At what altitude are the autopilot systems powered by separate sources with three autopilots engaged?
1500’
Can the glideslope be captured prior to Localizer intercept?
No
When TO/GA is pushed for go-around on approach, what autothrottle mode would be displayed on the flight mode annunciation, if the A/T is armed?
THR (thrust to maintain 2000fpm climb commanded)
THR REF if pushed a second time (full GA thrust commanded)
What climb rate is achieved during a go-around with TO/GA pushed?
2000fpm
What autothrottle mode is activated with the second push of the TO/GA switch?
THR REF
When power is first applied to the airplane, what altitude is displayed in the MCP altitude window and PFD?
10,000’
How can you disarm VNAV, LNAV, LOC, and APP modes when armed?
Press button again
Which PFD annunciation is association with a fail operational automatic landing, and which one is associated with a fail passive automatic landing?
LAND 3
LAND 2
When does the ROLLOUT mode activate?
5’ RA
What controls are used by the AFDS to steer the airplane on the localizer centerline after touchdown?
Rudder and NWS
When does the FLARE mode activate during Autoland?
50’ RA
When do the autopilots start the flare maneuver?
50’ RA
When do the autothrottles retard to idle during Autoland?
25’ RA
When does the FLARE mode de-activate?
Touchdown
During Autoland, what action disconnects the autothrottles?
Activation of reverse thrust
What conditions would cause the autothrottles to disconnect and subsequently cannot be re-connected?
Dual FMC failure
2 or more engines shutdown
Can the autothrottles be reconnected if the FMC Master switch is switched?
Yes
During takeoff, when TO/GA is selected, which autothrottle mode is active?
THR REF
When does the autothrottle annunciation change to HOLD during takeoff?
65kts
When is barometric altitude recorded by the FMC during takeoff?
100kts
At liftoff, with TO/GA as the roll mode, what roll command is maintained?
Ground Track
If an engine failure occurs on the ground, what is the pitch command target Speed at liftoff?
V2 or airspeed at liftoff (greater of) limited to max V2+10
At acceleration height what speed commands are established by pitch as the flaps are retracted?
5kts below takeoff flap placard speed
When is TO/GA mode terminated after takeoff?
selecting any other pitch and roll mode, or
activation of LNAV/VNAV modes
When does the autopilot control the rudder during multi A/P approaches?
When LAND 2/3 annunciated
At what two altitudes will runway alignment occur during multi A/P approaches during crosswinds, with all engines?
500’
200’
What pitch is commanded by the AFDS when TO/GA is pushed in a windshear recovery on approach?
15deg or slightly below pitch limit (lower of)
How does the automatic flight control system provide stall protection?
prevents speed reduction below min maneuvering speed
Describe flight envelope speed protection.
A/T and AFDS independently provide stall and overspeed protection by introducing pitch requirements and thrust between idle and THR REF
What speed protection margin is used by the AFDS in max operating, flap placard speed, and gear extended speeds?
5kts
What three conditions prevent the AFDS and autothrottle from providing speed protection?
Pitch mode in V/S
FMC data invalid
Engine failure above max EO altitude
