Term
Describe the elevator feel system |
|
Definition
Provides artificial feel at control columns Force increases as airspeed increases |
|
|
Term
How is elevator feel effected with a loss of HYD 2 and 3? |
|
Definition
Mechanical springs provide feel force Feel force is no longer a function of airspeed |
|
|
Term
What can you do if you lose elevator control due to a jam? |
|
Definition
When significant manual force is applied to the control column, shear outs between the inboard and outboard elevators allow elevator control to be regained |
|
|
Term
Which elevator panels are displayed on the position indicator? Which move with control column inputs? |
|
Definition
Indicator: left and right outboard
Control column: left and right inboard |
|
|
Term
How is stabilizer trim greenband calculated? |
|
Definition
CG, gross weight and takeoff thrust inputs entered into the FMC |
|
|
Term
How does the aircraft provide a crosscheck to ensure the correct greenband has been selected? |
|
Definition
A nose gear oleo pressure switch position is compared to the selected greenband |
|
|
Term
What happens when control wheel trim is used with an autopilot engaged? All 3 autopilots? |
|
Definition
Single - autopilot disengages and stabilizer trim moves Multiple - control wheel trim switches are inhibited |
|
|
Term
What happens when alternate trim switches are used with any number of autopilots engaged? |
|
Definition
Alternate trim switches override autopilot trim Autopilot does not disengage |
|
|
Term
Describe the function of the alternate trim switches |
|
Definition
They provide trim commands through a separate electric channel |
|
|
Term
Describe the function of the Stabilizer Trim Cutout switches, AUTO position |
|
Definition
Automatic cutout of respective hydraulic system if uncontrolled stab trim is detected |
|
|
Term
Describe the function of the Stabilizer Trim Cutout Switches, ON position |
|
Definition
Automatic cutout is overridden STAB TRIM UNSCHD caution msg will still display |
|
|
Term
What occurs when a Stabilizer Trim CUTOUT switch is in CUTOUT? |
|
Definition
Shuts off related hydraulic power to stabilizer trim Stab trim is at half the normal rate |
|
|
Term
Which spoilers provide roll control? |
|
Definition
5 outboard panels on each wing |
|
|
Term
Which spoilers function as speedbrakes in flight? How much travel? |
|
Definition
4 inboard panels on each wing - 2 inboard spoilers extend to mid‐travel - 2 middle spoilers extend to full travel |
|
|
Term
Which spoilers function as ground spoilers? |
|
Definition
All 6 spoiler panels on each wing |
|
|
Term
Which spoilers are displayed on the EICAS status display? |
|
Definition
#4 and #12 Speedbrake position on left wing only |
|
|
Term
When do the spoilers extend during landing, if the speedbrake lever is ARMED? |
|
Definition
Thrust levers 1 and 3 near closed Main landing gear on ground |
|
|
Term
When do the spoilers extend during landing if the speedbrake lever is NOT Armed? |
|
Definition
Thrust levers 1 and 3 near closed Reverse thrust levers 2 or 4 in idle Main landing gear on ground |
|
|
Term
What action provides automatic spoiler function during an RTO? |
|
Definition
Thrust levers 1 and 3 near closed Reverse thrust levers 2 or 4 in idle Main landing gear on ground |
|
|
Term
For go-around protection, what action drives the speedbrake lever to the DN position? |
|
Definition
Thrust lever 1 or 3 advanced from the closed position, regardless of whether ground spoilers were automatically or mechanically selected |
|
|
Term
SPEEDBRAKE EXT caution msg |
|
Definition
RA between 800' and 15' Flaps in landing configuration 2 or more thrust levers fwd of closed position |
|
|
Term
How does the aileron lockout system work? Why? |
|
Definition
Locks the outboard ailerons in a neutral position at high airspeeds
Prevents over‐controlling at high airspeeds Provides the required roll authority at low airspeeds |
|
|
Term
What would happen if you use aileron trim with the autopilot engaged? |
|
Definition
The aileron neutral point is repositioned When the autopilot is disengaged, the wheel and ailerons move to the repositioned aileron neutral point
The airplane responds with roll proportional to the amount of aileron trim input |
|
|
Term
How do the rudder ratio changers work? |
|
Definition
Reduce rudder response to pedal inputs as airspeed increases |
|
|
Term
What happens if a Rudder Ratio failure occurs? |
|
Definition
Rudder response remains the same as when the failure occurred regardless of airspeed |
|
|
Term
|
Definition
Yam Damper fault During IRS alignment All 3 IRSs are inop |
