Autoflight

Question 1

What does a flashing 8 mean in the airspeed window?

Answer 1

Selected speed is greater than the over speed limit

Question 2

What does a flashing A mean in the speed window?

Answer 2

Selected speed is less than the minimum speed

Question 3

The speed control on the MCP automatically changes to Mach above what altitude?

Answer 3

26,000 ft

Question 4

What does a lit up button on the MCP mean?

Answer 4

That the mode can be deselected.
It does NOT mean a specific mode is active.

Question 5

After the APP light extinguished on an approach, how can the APP mode be disengaged?

Answer 5

Pushing TOGA

Disengaging the autopilot by turning off both FDs

Selecting a different frequency in one of the VHF Nav receivers

Question 6

The autothrottle servos are de-energized in what two modes? Allowing the pilot to manually adjust thrust lever position

Answer 6

THR HOLD

ARM

Question 7

What does a white A/T LIMIT above the engine N1 indicators mean?

Answer 7

The FMC is not providing limits to the autothrottle system

Or

The system is using a degraded N1 thirst limit from the EEC

Question 8

The three columns on the FMA represent what? (In order L to R)

Answer 8

Auto throttle mode
Roll mode
Pitch mode

Question 9

What does FD indicate on the AFDS?

Answer 9

That the flight director is turned on, but the autopilot is either off or in CWS mode

Question 10

What does an amber CWS R or CWS P in amber below the FMA mean?

Answer 10

Control wheel steering is engaged in the roll or pitch mode respectively

Question 11

MA (master) displays above which flight director?

Answer 11

Which ever is selected in first (with no autopilot engaged)

Which ever FCC is controlling the autopilot (autopilot on)

Question 12

An amber FD displayed on the PFD means what?

Answer 12

There is a fault in the FD system. Command bars should also be missing

Question 13

Flight control computer A/B is selected for use how?

Answer 13

Whichever autopilot master is turned on first

Question 14

Minimum altitude for autopilot engagement?

Answer 14

1000 ft AGL

Question 15

What happens if you press/disengage an active autopilot mode?

Answer 15

The aircraft reverts to CWS in that mode (pitch/roll), CWS P/R illuminates on the PFD, A/P disengage light flashes amber, that pitch or roll mode must be manually controlled

Question 16

A/P engagement is only allowed if two pilot controlled conditions are met, what are they?

Answer 16

No force is being applied to the control wheel

Stabilizer trim AUTOPILOT cutout switch is in the NORMAL position

Question 17

What happens if you press the other autopilot CMD switch while an autopilot is active?

Answer 17

The autopilot simply transfers to the other FCC. No disengagement occurs

Question 18

T/F: Aileron trim can bd used with the autopilot engaged

Answer 18

FALSE
THE USE OF AILERON TRIM IS PROHIBITED ANY TIME THE AUTOPILOT IS ENGAGED

Question 19

What are all the ways to disengage the autopilot?

Answer 19

Pushing the autopilot disconnect on the control wheel or MCP (bar down)

Pushing the illuminated CMD mode on the MCP

Activating either pilots control wheel trim switch

Moving the STAB TRIM AUTOPILOT cutout switch to CUTOUT

Pushing TOGA with AP engaged below 2,000 ft RA

Pushing TOGA with AP engaged above 2,000 ft RA with flaps not UP or G/S engaged

Question 20

What four failures cause autopilot disengagement?

Answer 20

Either L or R IRU fails (fault light illuminates)

The respective hydraulic system pressure is lost

Loss of electrical power

Loss of a sensor input which prevents proper autopilot operation

Question 21

A/P disengage light illuminates steady red for what two conditions?

Answer 21

Altitude acquire mode inhibited during A/P go around if not trimmed for single A/P operation

When the disengage light test switch is held in position 2, or when the automatic ground system test fails

Question 22

What does the STAB OUT OF TRIM light mean?

Answer 22

Autopilot is not trimming the stabilizer properly. Only can illuminate when the autopilot is engaged

Question 23

During takeoff at ___ kts the auto throttle switches from ____ mode to ____ mode. This does what to the autothrottles?

Answer 23

84 kts
N1 mode to THR HLD mode
This disengages the servos and the crew can manually adjust the thrust levers if needed

Question 24

As the autothrottles reduce thrust for an idle descent, ____ is displayed on the FMA.

Once the thrust levers reach the idle position ____ replaces ____ on the FMA.

Answer 24

RETARD

ARM replaces RETARD

Question 25

When you press the TOGA button for a go around once, what happens? Twice?

Answer 25

First press commands a reduced thrust go around to achieve between 1,000-2,000 ft/min climb.

The second ores commands a max thrust go around
