Term
What speed protection margin is used by the AFDS in max operating, flap placard speed, and gear extended speeds?
Definition
5 knots
Term
What two conditions prevent the AFDS and autothrottle from providing speed protection?
Definition
V/S pitch mode
Engine failure above max engine­‐out altitude
Term
The outer Bank Limit selector applies to which roll mode?
Definition
HDG SEL
Term
What does an amber horizontal line displayed through the affected ACTIVE pitch or roll mode indicate?
Definition
Flight mode fault is detected
Term
When is VNAV deactivated?
Definition
TO/GA, FLCH SPD, V/S, ALT, or G/S pitch mode

Dual FMC failure
Term
When does LNAV activate when armed?
Definition
Above 50' and in position to turn onto the active route leg

In flight, when within 2 ½ miles of the active leg
Term
What conditions would cause the autothrottles to disconnect and subsequently cannot be reconnected?
Definition
Both FMCs fail
Two or more engines are shut down
Term
How are the autothrottles re-engaged? Pitch modes?
Definition
ALT, V/S or G/S:
SPD switch

VNAV or FLCH SPD:
Cycle the A/T ARM switch
Term
In flight, when is TO/GA armed?
Definition
Flaps out of up, or
Glideslope captured
Term
What speed is set in the IAS/Mach window and PFD when power is first applied to the airplane? Altitude?
Definition
200 knots
10,000'
Term
What initial pitch attitude is commanded by the flight director when the flight director is turned on, while on the ground?
Definition
8° nose up
Term
Will the autothrottles operate if you don’t push TO/GA for takeoff by 50 knots?
Definition
No
Autothrottles will be inhibited until 400'
Term
If an engine failure occurs on the ground, what is the pitch command target speed at liftoff?
Definition
V2, or airspeed at liftoff, whichever is greater
Term
At liftoff, with TO/GA as the roll mode, what roll command is maintained?
Definition
Ground track
Term
During takeoff, when TO/GA is selected, which autothrottle mode is active?
Definition
THR REF
Term
What autothrottle mode is activated with the second push of the TO/GA switch?
Definition
THR REF, at full go­‐around thrust
Term
How could you select climb thrust after takeoff or go-around?
Definition
Push the THR switch
Term
When is TO/GA mode terminated after takeoff?
Definition
By selecting any other pitch and roll mode, or
By activation of LNAV/VNAV modes
Term
If a VNAV descent is initiated prior to T/D, what is the pitch mode?
Definition
VNAV SPD
Term
What Autothrottle flight mode annunciations would you have when using FLCH SPD in a descent, to include subsequent altitude capture?
Definition
THR, followed by HOLD
A/T mode changes to SPD when altitude captured
Term
Which PFD annunciation is associated with a fail operational automatic landing?
Fail passive automatic landing?
Definition
LAND 3 for fail operational
LAND 2 for fail passive
Term
With the approach (APP) switch pushed, at what intercept track angle does the AFDS capture the localizer?
Definition
120° of the localizer course
Term
Can the glideslope be captured prior to localizer intercept?
Definition
No, glideslope capture is inhibited until localizer capture and the intercept angle is within 80° of the localizer course
Term
How can you de­‐select approach mode AFTER localizer and glideslope are captured?
Definition
Select TO/GA
Disengage autopilot and turn both F/D switches off
Term
How does the autopilot correct for crosswinds during LAND 2 & 3 approaches?
Definition
Introduces a sideslip at 500' and 200', depending on crab angle
Term
During multiple A/P approaches, how does the A/P maintain runway alignment if an engine failure occurs prior to the approach? During approach?
Definition
Prior: introduces a sideslip at 1300'

During the approach: when the engine failure is detected
Term
During autoland, what action disconnects the autothrottles?
Definition
A reverse thrust lever is raised to reverse idle
Term
When TO/GA is pushed for go­‐around on approach, what autothrottle mode would be displayed on the flight mode annunciation?
Definition
THR mode
Term
What climb rate is achieved during a go­‐around with TO/GA pushed?
Definition
2,000'/min
Term
What pitch is commanded by the AFDS when TO/GA is pushed in a windshear recovery on approach?
Definition
15° pitch‐up or slightly below the pitch limit, whichever is lower
