What should be activated before you are able to lower the flaps via the emergency hydraulic system?
The emergency landing gear handle
What is the emergency flap operation powered by?
The hot battery bus
Is the normal flap operation and position indication available when the battery bus have failed or when only the aux battery is powering the A/C?
No
The speed brake increases drag allowing you to do what two things?
DecelerateIncrease descent rate without increasing speed
Where does the speed brake system receive its power from?
The generator bus
Is the speed brake only operated by the electric system?
No also the hydraulic system
How many positions are there on the speed brake switch?
3
Once extended, what can make the speed brake retract?
Forward movement of the speed brake switchExtension of the flapsPLC moved to max
Is the speed brake operated by the emergency hydraulic system?
No
Who will the speed brake respond to (front or rear cockpit)
Neither - the one who makes the last input
What way will the nose pitch when the speed brake is extended?
Up
What are the three methods of steering the AC on ground?
Differential breakingNose wheel steeringUse of rudder

12* and 80*
What is the name of the device that mechanically turns the nose wheel strut?
The rotary actuator
What does the centering valve do?
Returns the wheel to a centered position before the nose wheel is being extended or retracted.
Is the NWS a part of the selector manifold and the emergency system?
No neither
What should you do if the NWS system fails on ground?
Deactivate it and use differential breaking instead.
What is the two functions of the wheel brakes?
