122
Q

ELACs control?

A

Elevator, Aileron, Trimmable THS

123
Q

SECs control?

A

Spoilers, Backup elevator, backup THS

SEC 1+2 provide backup elevator + THS

124
Q

FACs control?

A

Rudder, Provide characteristic speed, Aircraft weight calculations, Winshear warnings, Several other functions

125
Q

Normal Law protections are?

A
  • High Speed
  • High angle of attack (ALPHA protection AOA)
  • Load factor 2.5/-1.0, 2.0/0.0
  • Pitch Attitude 30up/15down
  • Bank angle 67
126
Q

Alternate Law protections are?

A
  • Load factor
  • Hight speed stability
  • Low speed stability
127
Q

Direct Law protections are?

A

None

128
Q

Mechanical Law has?

A

Only rudder and manual trim, thrust for direction

129
Q

Abnormal Attitude Law is what?

A
  • Bank angle above 125 degrees
  • Pitch attitude 50 degrees nose up and down 30 degrees nose down
  • Speed below 60-90 knots
130
Q

What law do you go into when leaving Abnormal Attitude Law?

A
  • When the aircraft returns within the normal flight envelop.
  • Pitch Alternate law is active
  • Roll Direct Law is active
  • Yaw Alternate Law is active
131
Q

What happens at ALPHA prot?

A
  • AOA is commanded instead load factor
  • Speed brake retracted
  • Autopilot disengages
  • Pitch trim up is inhibited
132
Q

When do wing tip brakes engage to lock the slats/flaps (4 red collared circuit brakers)?

A
  • Runaway
  • Overspeed
  • Asymmetry
  • Movement un-commanded
133
Q

When are spoilers inhibited?

A
  • SEC 1 and SEC 3 failure
  • ALPHA prot or ALPHA floor
  • Flaps in configuration FULL (configuration 3 for A321)
  • Failure of one Elevator
  • TOGA on thrust levers
134
Q

What happens at ALPHA Prot?

A
  • Nose up trim is inhibited
  • The autopilot if engaged disengaged
  • Pitch command change from load factor to angle of attack
    (can be override by pilot)
135
Q

ALPHA Max speed is generated by what?

A

By the FACs

136
Q

What is actual angles of attack Alpha Prot and Alpha Max?

A

Computed by the ELACs based of AOA not airspeed.

137
Q

What is Alpha floor A.FLOOR?

A

Is a function of the autothrust system and only available in normal. Provides TOGA thrust automatically regardless of thrust lever position. Alpha Floor is available from lift off to 100ft RA with the aircraft in landing configuration.
