Q

FCM

A

Flight Control Module

17
Q

Flight Control System: NORMAL MODE

A

Provides software based airspeed gain schedules and control limits to the P-ACE

18
Q

Flight Control System: NORMAL MODE - High level functions

A

Elevator control laws scheduling with airspeed
Auto-thrust compensation with elevator
AOA limiting with elevator offset
Rudder airspeed gain scheduling and stroke limiting
Yaw damper and turn coordination via AFCS
Rudder flight authority
Roll spoiler scheduling with airspeed and speedbrake deployment
Configuration change compensation with horizontal stabilizer due to speed brakes actuation

19
Q

Flight Control System: Direct mode

A

The FCM is removed from the control loop and the control limits default to values set by hardware in the P-ACE

20
Q

Flight Control System: Direct mode - extra

A

Direct mode of ops is primarily the result of loss of data from all FCM or multiple ACE failures
Operation is defaulted to fixed control laws config
Control input provided by captain and FO sensors is sent directly to the surface

21
Q

PBIT

A

Power-up Built In Test

Reduces flight control exposition to latent faults ensuring that the system remains operable

22
Q

PBIT covers what two systems?

A

Electrical and hydraulic

Last for 50hrs

23
Q

Electrical PBIT

A

Detects out of tolerance conditions, and failures in FCMs, P-ACEs and SF-ACEs

Performed once AC power established, takes 3 mins

24
Q

Hydraulic PBIT

A

Functional test of flight control actuators
Only performed when all three HYD systems are pressurized

Takes 1 min to complete

25
Q

FBW backup battery

A

Elevator and rudder actuations for at least 15 mins

26
Q

Stabilizer trim priority

A

Backup switches
Captain
FO
FCM auto trim commands

27
Q

Trim following RAT deployment

A

Works at half speed

28
Q

Flap/slat deployment with RAT

A

Half speed

No flap position past flaps 3

29
Q

3 modes of operation for multi-function spoilers

A

Roll control
Speed brakes
Ground spoilers

30
Q

Inboard ground spoiler deflection

A

60 degrees

31
Q

Outboard ground spoiler deflection

A

40 degrees

32
Q

Ground spoiler command conditions

A

WOW
Wheel speed above 45kt or airspeed above 60
Thrust Lever Angle (TLA) below 26 degrees

33
Q

Ground spoiler retract command conditions

A

Wheel speed below 45kt for at least 5 seconds
If throttles moved past 35 degrees Thrust Level Angle (TLA)

Bounced landing the FCM holds “on ground” signal for 5 seconds after the WOW signals “in air”. If pilot commands TLA greater than 24 degrees the ground spoilers are retracted

34
Q

Do ground spoilers work in direct mode?

A

No

35
Q

Speed brake deflection

A

30 degrees

36
Q

Speed brakes will auto retract if

A

Slat/flap 2 or more selected

TLA of 70% or more

37
Q

No speed brake below __ KIAS

A

180
