In Pitch Normal Law Flight Mode, pitch trim is:

Auto ground spoilers are armed by pulling the spoiler lever up to expose a white collar. A memo on the E/WS confirms arming.

Which controls are used for the mechanical backup?

When is the Flight Mode active?

There are _____ that control the aircraft in pitch.

Which of the following statements best describes the Load Alleviation function (LAF)?

If electrical power to a SEC fails:

The flight control surfaces are _____ controlled and _____ actuated.

When deploying flaps when airborne, selecting 1 on the flap lever only moves the slats - i.e. configuration 1 is achieved rather than 1+F.

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

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.

Seven flight control computers process pilot and autopilot inputs according to normal, alternate, or direct flight control laws.

Mechanically backed-up control surfaces:

Which of the following statements is correct concerning the elevator aileron computers (ELACs):

Two control surfaces that have mechanical backup are:

When the flaps are extended, the ailerons:

You can degrade directly from Normal Law to Direct Law with gear down and a dual radio altimeter fault.

In the event of a complete loss of electrical flight control signals, the airplane reverts to a _____ mode.

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 _.

The flight control surfaces are _ controlled and _ actuated.
