When will override of rudder pedals cause autopilot disengagement?

Answer 7

Only with LAND 2 or LAND 3 annunciated

Question 8

How does the autopilot react to engaged mode degredation?

Answer 8

Remains engaged in an attitude stabilizing mode initially

Question 9

How is the flight director affected by a mode degredation?

Answer 9

F/D initially command an attitude stabilizing command based on inertial data

Question 10

With the F/D off, will a TOGA selection cause them to appear?

Answer 10

Yes, if speed is over 80kts and flaps are out of UP

Question 11

How is the F/D affected by overspeed or stall?

Answer 11

F/D bars will disappear

Question 12

During an autoland, will degredation to LAND 2 be displayed on EICAS?

Answer 12

Yes, if above 200 ft

Question 13

What two occasions will cause a green box to appear around an FMA mode?

Answer 13

1. When a mode is first activated/engaged(green box appears for 10s)
2. When amber line through a degraded mode is removed

Question 14

Which A/T mode controls vertical speed?

Answer 14

Pitch mode

Question 15

What is the A/T controlling to when THR is annunciated?

Answer 15

A/T applies thrust to maintain V/S REQD by pitch mode

Question 16

At what distance to an active route leg will LNAV engage, if armed?

Answer 16

2,5 nm

Question 17

What are the conditions for the roll mode ATT to engage?

Answer 17

If A/P or F/D engaged with bank angle more than 5 deg

Question 18

When is TOGA mode armed in flight?

Answer 18

Whenever flaps are out or G/S captures

Question 19

When does ROLLOUT mode engage?

Answer 19

Below 2 ft RA on landing

Question 20

What are the bank angle limits in ATT mode?

Answer 20

5-30 deg
Less than 5 deg = rolls back to level
More than 30 deg = Rolls back to 30 deg

Question 21

In TOGA pitch mode, what can the maximum target speed be?

Answer 21

V2+25 kts

Question 22

Where does the AFDS get the V2 speed; MCP or CDU?

Answer 22

AFDS uses the speed set in the MCP IAS/MACH windoe

Question 23

When will VNAV engage if armed for T/O?

Answer 23

At 400 ft

Question 24

After an altitude conflict, how is VNAV ALT mode cancelled?

Answer 24

By changing the altitude value set in the MCP ALT window and pushing the ALT selector, or changing the pitch mode

Question 25

When does FLARE mode engage?

Answer 25

During autoland between 60-40 ft RA

Question 26

Can the A/T be operated without the flightdirector or autopilot?

Answer 26

Yes, but only in THR REF, SPD, HOLD or IDLE modes

Question 27

When does IDLE mode occur?

Answer 27

IDLE displayed when A/T moves thrust levers to idle

Question 28

Can the A/T engage automatically?

Answer 28

Yes, if armed and no AP or F/D is active

Question 29

Can the A/T be engaged if only one servo motor is servicable?

Answer 29

Yes

Question 30

In which mode will the A/T not reposition the thrust levers?

Answer 30

HOLD mode

Question 31

What action causes a normal A/T disconnection during landing?

Answer 31

When either thrust reverser lever is raised to reverse or thrust levers are manually overridden during a manual landing

Question 32

What are the initial TOGA F/D commands upon engagment?

Answer 32

Pitch command is 8 deg nose up

Roll command is wings level

Question 33

During take-off, when can the TOGO switches be used for A/T engagement?

Answer 33

Speed less than 50 kts on T/O roll or above 400 ft(if not activated by 50 kts)

Question 34

What does selection of TOGA above 80 kts do?

Answer 34

Disarms LNAV and VNAV

Question 35

What type of altitude is used for LNAV and VNAV engagements?

Answer 35

LNAV: 50 ft RA
VNAV: 400 ft above rwy elevation

Question 36

What is the maximum speed commanded after lift off, if an engine fails?

Answer 36

V2+15

Question 37

What does a TOGA selection do immediately after T/O?

Answer 37

Removes T/O and climb derates and assumed temp reduction.
