Question 6

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?

Answer 6

THR (thrust to maintain 2000fpm climb commanded)
THR REF if pushed a second time (full GA thrust commanded)

Question 7

Question 16

When do the autothrottles retard to idle during Autoland?

Answer 16

25’ RA

Question 17

When does the FLARE mode de-activate?

Answer 17

Touchdown

Question 18

During Autoland, what action disconnects the autothrottles?

Answer 18

Answer 19

Dual FMC failure
2 or more engines shutdown

Question 20

Can the autothrottles be reconnected if the FMC Master switch is switched?

Answer 20

Yes

Question 21

During takeoff, when TO/GA is selected, which autothrottle mode is active?

Answer 21

THR REF

Question 22

Answer 22

65kts

Question 23

When is barometric altitude recorded by the FMC during takeoff?

Answer 23

100kts

Question 24

At liftoff, with TO/GA as the roll mode, what roll command is maintained?

Answer 24

Ground Track

Question 25

If an engine failure occurs on the ground, what is the pitch command target Speed at liftoff?

Answer 25

V2 or airspeed at liftoff (greater of) limited to max V2+10

Question 26

At acceleration height what speed commands are established by pitch as the flaps are retracted?

Answer 26

5kts below takeoff flap placard speed

Question 27

When is TO/GA mode terminated after takeoff?

Answer 27

selecting any other pitch and roll mode, or
activation of LNAV/VNAV modes

Question 28

Answer 29

500’
200’

Question 30

What pitch is commanded by the AFDS when TO/GA is pushed in a windshear recovery on approach?

Answer 30

15deg or slightly below pitch limit (lower of)

Question 31

How does the automatic flight control system provide stall protection?

Answer 31

prevents speed reduction below min maneuvering speed

Question 32

Describe flight envelope speed protection.

Answer 32

A/T and AFDS independently provide stall and overspeed protection by introducing pitch requirements and thrust between idle and THR REF

Question 33

What speed protection margin is used by the AFDS in max operating, flap placard speed, and gear extended speeds?

Answer 33

5kts

Question 34

What three conditions prevent the AFDS and autothrottle from providing speed protection?

Answer 34

Pitch mode in V/S
