push autopilot disengage switch, pushing either TOGA switch w/ a single AP engaged in CWS or CMD; below 2000’ RA or with flaps not up or glideslope engaged; pushing either TOGA switch with a single AP engaged in CWS or CMD above 2000 FA with flaps not up or glideslope engaged. Pushing either TOGA switch after touchdown with both APs engaged in CMD. Pushing an illuminated engage switch. Pushing the AP disengage bar down. Activating either pilots control wheel switch. Moving the STAB TRIM AUTOPILOT CUTOUT switch to CUTOUT. Either L or R IRS system FAULT light are illuminated. Loss of electrical power or a sensor input which prevents proper operation of the engaged autopilot and mode. Loss of hyraulic system pressure.

How many RAs are there?

Answer 11

2

Question 12

With one RA inop, the autopilot will disconnect 2 seconds after ____ and ____ capture

Answer 12

LOC; Glideslope

Question 13

T/F: Command pitch and roll modes must be engaged for the FD to show.

Answer 13

true

Question 14

FD commands are the same as Autopilot except:

Answer 14

T/O mode is a flight director mode only
Dual FD guidance is availble for single eng ops
FD has no landing flare capability

Question 15

FD command bars retract from view at ~ ______ on an ILS approach

Answer 15

50 feet RA

Question 16

With both FD switches on, the logic for both pilots FD modes is controlled by the _______.

Answer 16

Master FCC.

Question 17

Master FCC logic

Answer 17

1. With neither AP engaged, the FCC for 1st FD turned on is Master (MA)
2. With 1 or both APs engaged in CMD, the FCC for the first AP in CMD is the master FCC, regardless of which FD is on first.

Question 18

How can you tell the FDs are in independent mode?

Answer 18

Both MA lights are on in the MCP.

Question 19

If a generator fails during a FD TO or GA or while in Dual FD approach mode below 800’, the FCC on the unaffected side positions the FD on which side?

Answer 19

both sides.

Question 20

What does FD mean above the ADI?

Answer 20

FD is on and the AP is either OFF or in CWS.

Question 21

What does CWS P mean?

Answer 21

pitch mode is engaged in CWS mode

Question 22

What does CWS R mean?

Answer 22

the roll mode is engaged in CWS.

Question 23

What does SINGLE CH mean?

Answer 23

annunciated for single AP ILS approaches. It appears after Localizer capture.

Question 24

What happens when you push CWS on the MCP?

Answer 24

engages AP in pitch and roll axes and displays CWS P and CWS R on FMAs.

Question 25

If in CWS mode, when you release control pressure, what happens?

Answer 25

the AP holds existing attitude.

Question 26

If in CWS mode and aileron pressure is released within 6 degrees or less bank, the AP rolls ____________.

Answer 26

wings level and holds existing heading.

Question 27

Heading hold feature-bank

Answer 27

below 1500 FA with gear down
after FD VOR capture with TAS 250 kts or less
after FD LOC capture in APP mode

Question 28

How can you tell that a mode is armed in the FMA boxes

Answer 28

Smaller white letters underneath the larger green letters.

Question 29

What does GA signify?

Answer 29

ATS maintain thrust at reduced GA setting

Question 30

When you see RETARD, what do you know?

Answer 30

The ATS are moving to the aft stop and then you will see ARM mode.

Question 31

What does a white ARM mean?

Answer 31

no ATS mode is engaged. thrust lever servos are inhibited. Pilot can set thrust levers manually. Minimum speed protection is provided.

Question 32

How do you arm TOGA for takeoff?

Answer 32

both FD switches on and pushing either TOGA switch.

Question 33

How is pitch shown on FDs on takeoff?
