(Sec 4.010 p 7)

Question 9

How is the master FCC determined?

Answer 9

1) first F/D switch selected, or
2) with one or both A/Ps engaged in CMD, first A/P engagement

(Sec 4.010 p 8)

Question 10

What are the required conditions for A/P engagement?

Answer 10

• no force applied to control wheel
• the STAB TRIM AUTOPILOT cutout switch is at NORMAL

(Sec 4.010 p 11)

Question 11

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

Answer 11

With the A/P engaged the STAB OUT OF TRIM light illuminates when the autopilot is not trimming the stabilizer properly

Question 12

(Sec 4.010 p 18)

Question 13

What does the A/T LIM indication (white) on the Upper Display Unit mean?

(Sec 4.010 p 32)

Question 19

After engaging LVL CHG for a climb, what does the FMA annunciate for the Autothrottle mode?

Answer 19

• Disengage A/P and turn off both F/D switches
• Retune VHF NAV receiver

(Sec 4.010 p 55)

Question 21

You are on Autopilot climbing from 10,000 to FL200, in VNAV, with 20,000 in the FMC CRZ page and MCP Altitude window. Passing 11,000 you select ALT HLD, what will the aircraft do?

Answer 21

Hold uncorrected barometric altitude at the time switch is pressed

(Sec 4.010 p 36)

Question 22

What will happen after activating either TO/GA switch above 2,000 RA with flaps up and G/S not active?
