Automatic Flight

Question 1

Autothrottle is normally controlled by what system?

Answer 1

Left FMC

Question 2

How can the Autopilot be disengaged?

Answer 2

Either yoke A/P disengage switch,
Yoke electric trim activation,
A/P disengage bar,
Deselect engaged autopilot on MCP,
Control column force override,
TOGA
–Single A/P below 2,000’ OR flaps ext OR G/S capture
–Dual A/P after touchdown

Also,
Loss of respective hydraulic system pressure
L/R IRS failure or FAULT
STAB TRIM AUTOPILOT to CUTOUT

Question 3

With both FCC MA lights illuminated, how are the F/Ds being operated?

Answer 3

Independently by respective FCC

Question 4

What does an amber CWS R above the attitude indicator mean?

Answer 4

Control wheel steering ROLL mode

Holds bank angle between 6* and 30*

Hold heading if bank angle < 6*

Question 5

What are the three Flight Mode Annunciators (FMAs) left to right?

Answer 5

Auto-throttle, Roll mode, Pitch mode

Question 6

When will LNAV automatically disconnect?

Answer 6

End of active route

Route discontinuity

Intercepting approach course in VOR/LOC or APP

Selecting HDG SEL

Loss of capture criteria (3nm, or <90* and intercept prior to waypoint)

Question 7

What happens when deviating by 200’ or more from selected altitude?

Answer 7

Altitude alerter tone, and

Altitude box flashes amber

Inhibited while G/S captured or Flaps 25 or greater

Question 8

If you are >3nm from active route, how will LNAV engage?

Answer 8

Intercept course of 90* or less, and

Must intercept course prior to active waypoint

Question 9

Which FMA indicates power is removed from the A/T servos during takeoff?

Answer 9

THR HOLD

Occurs at 84 knots

Question 10

What is the initial TO/GA pitch attitude for a go-around? Single-engine?

Answer 10

15 degrees two-engines

13 degrees single-engine

Question 11

On a go-around with the A/T armed, thrust levels advance to? Second click?

Answer 11

First click – reduced thrust go-around (1,000 to 2,000 fpm)

Second click – Full G/A N1 limit

Question 12

During windshear on T/O or G/A, what does the F/D pitch command?

Answer 12

Target speed to +600fpm, then

15* until approximately stick shaker, then

Pitch which results in intermittent stick shaker, then

Increasing above +600fpm back to target speed

Question 13

How do you exit APP mode after localizer/glideslope capture?

Answer 13

TO/GA, or

Retune navigation radios, or

Disengage autopilot and recycle flight directors

Question 14

What does selecting the non-operating autopilot do?

Answer 14

Engages the other, selected autopilot

Except during APP mode, then dual A/P approach

Question 15

What mode will the A/T be in during a V/S descent?

Answer 15

MCP SPD

Question 16

What does the STAB OUT OF TRIM (amber) light indicate?

Answer 16

Autopilot is not trimming the stabilizer properly

Question 17

With the pitch mode in MCP SPD, how is aircraft speed controlled?

Answer 17

Adjusting target speed bug in MCP

Aircraft pitches for new speed

Thrust remains at idle or N1 (descent/climb respectively)

Question 18

Bank angle selectors sets maximum bank angle for which roll modes?

Answer 18

HDG SEL

VOR

Question 19

What is the MCP IAS/MACH display blank?

Answer 19

VNAV engaged (not in SPD INTV), or

A/T engaged in FMC SPD, or

2 Engine go-around

Question 20

What is minimum speed reversion not available?

Answer 20

VNAV path in a level segment, or

A/T is OFF in ALT HOLD or G/S capture, or

VNAV or V/S flaps 15-40
