Q

How many aileros?

A

25
Q

How many spoilerons?

A

2

26
Q

How many slats?

A

6 total

27
Q

The middle and outboard slats are tied together. True or False?

A

True

28
Q

What does the backup slat switch do?

A

Manually force opens the middle and outboard slats

29
Q

What is the slat inhibit speed?

A

Slats inhibited above 210 kts

30
Q

Do all slats come out during an auto slat extension?

A

No. Just middle and outboard slats when you exceed a certain angle of attack. But they will not if your speed is above 260 kts so they wont get damaged.

31
Q

How many flap panels are there?

A

4

32
Q

What happens when a flap asymmetry is sensed?

A

Flaps stop right there

33
Q

Which is the airbrake setting that can modulate?

A

Airbrake 1.

Airbrake 2 is just full up or full down

34
Q

When you apply airbrakes 2, do all 3 panels come up?

A

Yes. Including the spoileron

35
Q

How many flight data concentrator units are there?

A

5

36
Q

Explain the path of data to the flight controls?

A

Pilot input - Data Concentrator Units - Primary Flight Control Computers - ACMU - Flight control actuators

37
Q

What happens if all primary and secondary flight control computers fail?

A

Aircraft goes into back up mode. An analog computer is used, with direct control of the
horizontal stabilizer and spoilers through the pitch trim and rudder pedals.
The back-up mode uses internal sensors.

38
Q

How is roll controlled in back up mode law?

A

Using 2 spoilerons

39
Q

Will you have elevators if you are in back up law? How is pitch controlled?

A

No. The system uses the horizontal stabilizer.

40
Q

Are all primary and secondary flight computers active at all times?

A

Yes

41
Q

If we loose all 3 primary flight control computers, what law does the airplane go into?

A

Direct law. Only direct law is available with the secondary flight control computers.

42
Q

What happens if you release he stick going above a 35 degree roll angle?

A

Airplane returns to 35 degrees

43
Q

What happensif sidestick is released to neutral below 35° of bank?

A

Airplane maintains the new bank angle

44
Q

When is yaw manual trim available?

A

At all times

45
Q

When is roll manual trim available?

A

Only in Direct law

46
Q

The PFCS provides overspeed protection as well as stall protection even when the AutoPilot (AP) is not engaged. True or False?

A

True

47
Q

What is the function of the sidestick priority push button?

A

The sidestick priority pushbutton allows the crew members to select whether the left pilot, or the right pilot, or both control the airplane.

48
Q

What happens if both pilots use the side stick in the same or opposite direction at the same time?

A

Both pilots inputs are algebraically summed. In this case, an aural message “DUAL INPUT” and a tactile warning notifies the crew members of a both pilots flying situation.

49
Q

If the priority pushbutton is pressed for more than 30 seconds the PFCS will latch the current priority state, allowing the priority pushbutton to be released without losing priority. True or False?

A

True

50
Q

Can you reactivate a deactivated sidestick?

A

Yes a deactivated stick can be reactivated by momentarily pressing its priority pushbutton.

51
Q

What happens to the autopilot if you move the sidestick pretty hard?

A

Autopilot will disconnect

52
Q

What happens to the autopilot if you press a sidestick priority pushbutton?

A

Autopilot will disconnect

53
Q

The FCS test must be done with parking brake set and both engines running. True or False?

A

True

54
Q

What happens if the inboard slats are extended and you exceed an AOA of 26 degrees?

A

Inboard slats are retracted

55
Q

If you are using back up slats switch, which slats will extend?

A

Outboard and middle only

56
Q

Can retract slats after using backup slats switch?

A

Yes. Just reset the switch.

57
Q

What kind of flaps do we have?

A

Double slotted

58
Q

How many flaps per wing?

A

2

59
Q

The flaps can only be extended after the outboard and middle slat sections have been fully deployed. True or False?

A

True
