There is no difference
What effect does ALPHA LOCK have on the airplane
Inhibits slat retraction at high angles of attack, or low airspeeds
Illumination of the F/Os sidestick priority arrow indicates
Graphic shows FO Side Stick Priority red arrow illuminated pointing the CA
The Captain has pushed his takeover (priority) button

picture shows a normal PFD, no amber indications
No protection is active
For automatic spoiler extension to occur during landing
Both thrust levers must be at forward idle with the spoilers armed
How is the rudder actuated
Hydraulically
There are three high angle of attack protections. One of them is
Alpha max
What does the amber “PITCH TRIM” on the F/CTL page indicate
Pitch trim jam
When could the low energy warning “SPEED, SPEED, SPEED” be triggered?
When the airplane energy is insufficient to achieve a climbing flight path with pitch alone
What occurs when the sidesticks are moved simultaneously
Inputs are algebraically added
If angle of attack protection is active
The side stick is pushed forward to return to the normal mode
What is a characteristic of normal law pitch control in the flight mode
Normal law pitch mode is a load factor demand law
What is a characteristic of alternate law, due to multiple failures of redundant systems
The flare mode is not available
Speed brake extension is inhibited when
In flaps configuration full
Flap position 1 will extend only the slats when the
Flap lever is moved from 0 to 1 in flight
When the side stick is released with angle of attack protection active, the
Angle of attack returns to and maintains V_prot
What rudder trim inputs are required if an engine fails with an autopilot engaged
None. the Autopilot will trim automatically
The ECAM SPD BRK memo flashes amber if
Speed brakes are extended with thrust above idle
According to the graphic what is the maximum bank angle you can reach with the side stick fully deflected to the left or right
(picture shows wings level attitude Normal Law)
67 degrees
Loss of normal law is displayed on the PFD by
Picture of PFD with amber Xs left and right on the bank angle scale.
An amber “x” symbol on the bank angle scale
For automatic spoiler extension to occur during a rejected takeoff with the spoilers armed,
The wheel speed must be greater than 72 knots with both thrust levers at forward idle
A degraded flight control law may be caused by
Multiple system failures
Which flight control protection is available when in alternate law
Load factor protection
Under normal conditions, the ELACs control which flight control surfaces?
Ailerons, elevators, and horizontal stabilizer
How are the slats/flaps affected if one SFCC fails
All of the flaps and slats operate at half speed
If both ELACs fail, pitch control transfers to the
SECs
What happens to the stabilizer during the rollout after a normal landing
Automatically trims to 0
The beta target is displayed when
CONF 1-3, either engine EPR exceeds 1.25, and difference between EPRs exceeds .25
What is the sidestick to surface relationship in the normal law ground mode
There is a direct stick to surface relationship
Degradation of the flight control laws to mechanical backup mode is caused by a
Complete loss of all flight control signals
What happens to the spoilers if a SEC fault is detected or electrical power is lost
The affected spoiler automatically retracts
Which protection is never displayed on the PFD speedtape?
Alpha Floor
Which of the following occurs when high angle of attack protection is active
Speed brakes retract
You are in normal law hand flying the airplane in a 30 degree bank turn and release the stick. What will occur
The bank angle will remain at 30 degrees
When is the normal law flight mode active
From liftoff to flare mode engagement during landing at 50 feet RA
During a flaps full landing with the spoilers deployed, what occurs if the speed brake handle is manually moved aft
All spoiler panels retract
When both side sticks are operated simultaneously the addition is limited to
Single side stick maximum deflection
Speed brakes should not be extended more than one half when above FL_____ and less than Mach _____
310/.75
One of the three functions of the FACs is
Windshear detection
Under normal conditions, the SECs control which flight control surfaces
Spoilers
What is a characteristic of the flare mode
Automatically reduces airplane pitch at 30 feet
High speed protection is deactivated when the
The airspeed returns to VMO with side stick neutral
When landing gear is extended, pitch alternate law
Degrades to pitch direct law if autopilot not engaged
The ailerons droop 5 degrees when the
Flaps are extended
Holding the side stick takeover (priority) button for more than 40 seconds
Latches the other side stick
According to the graphic what has occurred
picture shows green A FLOOR in column one
Alpha floor protection has automatically set TOGA power
Normal law pitch attitude limits are displayed on the PFD by
green “=” on the pitch scale
According to the graphic, if you release the side stick now, the bank angle will
(picture shows bank at 45 degrees)
Automatically return to 33 degrees of bank
What do the sidestick priority lights indicate in the graphic below?
(Picture shows FO Side Stick Priority red arrow illuminated pointing at the CA and CAPT illuminated in Green)
