1

When will half bank be selected automatically

31,600' but it must be deselected for holding

2

What are the ways to turn off the autopilot

1. AP disengage button
2. AP disconnect bar
3. Red disconnect button on the yoke
4. Operating stab trim
5. TOGA button
6. YD disconnect

3

What will happen when the emergency flap switch is activated
PSM 11-60-1

20* flaps/20*slats

4

What control surfaces are controlled by all three hydraulic systems

Primary controls

5

What will happen if the stab trim is in motion for more than 3 seconds

Stab trim clacker

6

How can you actuate the rudders following a jam

YD disconnect and overpower jam

7

What actuated the flaps and slats

1. Flaps = 2 PDUs
2. Slats = 2 PDUs
3. Controlled by the SFECU

8

What would result in a SLATS/FLAPS HALFSPEED and would you still be able to operate them

Yes but only at half speed. It will operate on only 1 PDU because the other one failed
- it could also happen if on ADG power

9

What indications are there for a YD failure or disengagement

1. YD status message if only one fails
2. YD INOP Caution if both fail

10

What is the primary mode of the FCC

Pitch

11

What are the primary flight controls

1. Aileron
2. Elevator
3. Rudder

12

What are the secondary flight controls

1. Multi-function spoilers
2. Slats/Flaps
3. Aileron and rudder trim
4. Ground Spoilers

13

How many PCUs per hydraulic system

1

14

True or False
Most flight control surfaces can still be actuated by remaining HYD systems should any single HYD system fail

True

15

Which flight controls are powered by the electrical system

Slats/Flaps and stab trim

16

How do you verify autopilot engagement

Green AP with the green arrow on PFD

17

If you select a new altitude after the FMA is already flashing "ALTS CAP", which altitude will be captured

Initial one

18

What should happen after pressing TOGA buttons before takeoff

What mode would be on the autopilot if after takeoff you call for "gear up, speed mode" only

CLB

21

What happens if you select HDG mode twice

Roll mode

22

2 green lights on FCP

26

What heading is maintained in TO lateral mode
