Describe the function of the stabilizer trim cutout switches AUTO position
Supplies hydraulic power for stabilizer trim
Shuts off related system hydraulic power if unscheduled trim is detected
What is the effect on the flap system during engine reverse thrust operation?
Inboard and midspan leading edge flaps retract automatically
What surface component is moved when stabilizer trim inputs are made?
The leading edge of the moveable horizontal stabilizer
Stabilizer trim varies the angle of incidence of the horizontal stabilizer
What is the purpose of the yaw dampers?
To improve airplane lateral and directional stability and to provide turn coordination
How does the aileron lockout system work and what is its purpose?
Locks outboard ailerons in the neutral position at 238 kts and above
Permits full travel of the outboard ailerons at low airspeeds
Prevents over-controlling at high airspeeds
What system assists the 747-8 in pitch stability and landing flare?
Pitch augmentation control system (PACS)
During the landing flare, this system provides a small amount of nose up elevator as the airplane approaches the runway.
Does not move the control column
When does the 747-8 takeoff and landing tail strike protection activate?
PACS senses imminent tail strike and decreases elevator deflection
Activation of tail strike protection does not move the control column
Takeoff trim setting is calculated based on what factors?
Gross weight
CG
Takeoff thrust derate selection
Takeoff flap selection (-8 only)
Will manipulating the control wheel stabilizer trim switches with multiple autopilots engaged cause the autopilot to disconnect?
No
Stabilizer trim switches are inhibited with multiple autopilots engaged
Describe the OFF position of the landing gear.
Landing gear hydraulic system is depressurized.
How many degrees can the nose wheel steering system turn the nose gear with the tiller and how many degrees with the rudder pedals?
70 degrees in either direction with the tiller and 7 degrees with the rudder pedals
What does the BRAKE SOURCE amber light indicate when illuminated?
Active brake hydraulic sources (hyd 4, 1, and 2) have low pressure
