Autoflight

Question 1

What provides the necessary input data for Autopilot A?

Answer 1

FCC A

(Flight Control Computers) A, B; process inputs from the:
MCP
FMCs
Autothrottle Systems
Control Column/Wheel Position
Autopilot actuator position

FCC output - speed trim, Mach trim, altitude alert, a/p warning

Question 2

During descent a flashing “8” appears on the IAS/MACH Display window. What does this indicate?

Answer 2

The commanded speed cannot be reached because the commanded speed is greater than the overspeed limit.

Question 3

An illuminated MCP switch indicates the active navigation mode. (T/F)

Answer 3

False

Question 4

How is the First Officer’s flight director selected as the Master (MA)?

Answer 4

By selecting the First Officers F/D switch ON first.
By engaging autopilot B to CMD.

Question 5

How does Control Wheel Steering (CWS) allow the pilot to control the aircraft?

Answer 5

Moving the control wheel sends signals to the autopilot commanding pitch and roll.

Question 6

Which of the following are required to engage an autopilot in CMD?

Answer 6

The criteria to engage an autopilot are: No force applied to the control wheel, and The Stabilizer Trim AUTOPILOT Cutout switches in the NORMAL position.

Question 7

An autopilot can be disengaged by:

Answer 7

Activating either control wheel trim switch. Pushing and illuminated autopilot ENGAGE switch. Pushing the autopilot Disengage Bar.

Question 8

During climb, the autothrottle mode is N1. What does the autothrottle command?

Answer 8

A fixed thrust setting at climb N1.

Question 9

How is the autothrottle manually disengaged?

Answer 9

Pressing the A/T DISENGAGE switch on the thrust levers.
Select the A/T ARM switch OFF on the MCP.

Question 10

What is required to engage LNAV when the aircraft is greater than 3 miles from the FMC route?

Answer 10

Intercept the route prior to the active waypoint.
Intercept heading must be less than 90 degrees.

Question 11

What occurs during a descent in LVL CHG?

Answer 11

Pitch maintains the selected speed while the thrust levers retard to idle.

Question 12

During a descent in VNAV PTH, pitch maintains the vertical flight path while aircraft speed is secondary. (T/F)

Answer 12

True

Question 13

The SPD INTV switch allows the crew to change the FMC target speed while remaining in VNAV. (T/F)

Answer 13

True

Question 14

What speed does the flight director command after takeoff?

Answer 14

During liftoff the F/D targets V2+20 knots which is approx. 15 degrees nose up.

If an engine failure occurs the flight director automatically compensates by lowering its pitch commands.

If the airspeed is below V2 after liftoff the F/D pitch commands adjust to target V2 speed.

If the airspeed is between V2+20 the existing speed is targeted.

If the airspeed is greater than V2+20 the F/D commands adjust to target V2+20
