What is the maximum flap setting for in-flight use of the spoilers?

When is alpha floor not available?

On the ground, a combined side stick deflection indicator is shown as a white cross on the attitude indicator. This indicates control surface positions.

The ground spoilers retract:

Elevator actuation - Two electrically controlled hydraulic servojacks drive each elevator.

With an elevator fault, the remaining elevator remains operative, but its deflection limits are reduced to prevent excessive torsional loads on the tail. Normal flight is possible in this configuration. If the elevators are lost entirely, they are automatically set to the neutral position.

If both FAC’s fail, what happens to the rudder limiter?

Can you manually trim the rudder with the autopilot engaged?

The wing tip brakes are:

Can the rudders be moved with both FAC’s inoperative?

The "SPEED BRK" memo on the E/WD will flash amber if Speed brakes are extended and:

Should the active elevator actuator fail, elevator control is:

Mechanically backed-up control surfaces:

What control surfaces do the FACs control?

ALPHA/SPEED LOCK FUNCTION - This function inhibits slat retraction at high angles-of-attack and low speeds or high speeds.

In Pitch Alternate Law the low Speed stability (nose down command) can be overridden by the sidestick.

When the flaps are extended, the ailerons:

When is the Flight Mode active?

In normal law, what is the maximum bank angle you can reach with the side stick fully deflected?

What happens in the event of a single ELAC failure?

Which of the following will automatically reset after landing?

In Normal Law, what are the limits of Pitch Attitude protections with flaps Full.

Sidesticks provide electrical signals to the flight control computers. If both sidesticks are operated together:

Locked flaps or slats may be caused by the Wing Tip Brakes (WTB) locking the affected surface movement if _____ are detected.

The flight control surfaces are _ controlled and _ actuated.

Automatic rudder trim is provided at the rate of 5 degrees per second while the manual rudder trim rate is _ up to a maximum of _.
