normal and secondary
Moving the Primary Flight Computers Disconnect Switch to the DISC position puts the flight controls in the _____ mode.
While airborne in the flight control system NORMAL mode, the control wheel pitch trim switches:
cause the primary flight computer to change the pitch trim reference speed.
With the autopilot engaged, using the primary pitch trim switches are:
Inhibited. They will have no effect.

on a scale on top of each control column.
The EICAS caution message SPEEDBRAKE EXTENDED is displayed if speedbrakes are extended when:
flap lever in landing position
radio altitude is between 15 and 800 feet
either thrust lever is not at idle
(all of the above)
In the event of a complete electrical system shut-down, cables from the flight deck to the stabilizer and Spoilers ____ allow the pilot to fly straight and level until the electrical system is restarted.
4 and 11
Alternate pitch trim levers are linked via __________ to the stabilizer trim control modules (STCM)
via control cables...
TAC is available when the airspeed is above ____ knots.
During takeoff, the rudder becomes aerodynamically effective at approximately ____ knots
The thrust asymmetry compensation (TAC) system disengages:
if engine thrust data is lost.
In the secondary and direct flight control modes, the elevator feel system changes when the flaps are:
the flaps are extended out of UP
The Alternate Pitch Trim Levers should NOT be used with the autopilot
On the 777-200ER, flap and slat extension is inhibited whenever altitude is above approximately _______feet or airspeed is above ____ knots.
Some 777-300ERs are equipped with a tail skid system. How is this system activated?
Automatically and uses the main landing gear actuation system.
On the 777-300ER with the Flaps/Slats in the "Secondary Mode" the slats will retract to the midrange position with airspeed greater than______knots
On the 777-300ER aircraft to protect against inadvertent deployment during cruise, flap and slat extension from the UP position is inhibited when
speed is more than 275 knots or altitude is above approximately 20,000 feet.
What are the flap limit speeds on the 777-300ER for flaps 25 and 30?
Flaps 25.....200 knots
Flaps 30.....180 knots
On the -300ER, what is/are the authorized flap setting(s) for takeoff with TO thrust selected?
Both 15 and 20

Before liftoff, the thrust asymmetry compensation (TAC) system ________________ for the failed engine.
does not fully compensate....
The thrust asymmetry compensation (TAC) system significantly reduces uncommanded flight path changes associated with an engine failure or thrust differential by automatically adding rudder to minimize yaw. (T or F)?
In-flight, at what flap settings are Speedbrake operations allowed.
ALL flap settings.
In the Secondary Flap/Slat Mode, what will happen if the aircraft exceeds 256 knots (777-300ER) with the slats fully extended?

To supply power to the flight control DC electrical system
What does an illuminated DRIVE light on the integrated Drive Generator DISC switch represent?
IDG oil pressure is low.
What is the function of the ON position of the Engine Generator Control (GEN CTRL) switch?
It arms the generator breaker to close automatically when generator power is available.
Selecting the IFE/PASS SEATS switch OFF removes ALL power from the PAX seats and entertainment system, including seat motor power and power outlets. (T or F)?
What occurs when the CABIN/UTILITY power switch is selected OFF ?
