Flight Controls Atlas Flashcards
What flight controls comprise the primary flight controls? How are they operated?
Aileron, Rudder, elevator. They are operated hydraulically only (no manual reversion)
What flight controls comprise the secondary flight controls?
Spoilers
Stab trim
Flaps
Slats
Where are the primary FlightControl positions shown?
Status page on the EICAS
Where is the rudder trim indication located?
On the aft aisle stand
What does the rudder trim reposition?
Use of the rudder trim repositions the neutral point of the rudder and moved the rudder pedals
The right YAW damper requires inputs from what system for operation?
An IRU and the left hydraulic system
When will the RAT be automatically deployed?
If both engines fail above 80 kn
How can the RAT be retracted once it is released?
Once released it must be stored manually by maintenance personnel on the ground
What is the lowest airspeed that the RAT can provide adequate power to operate the flight controls?
130 knots
What systems are supplied hydraulic pressure by the RAT?
Flight controls through centre hydraulic pressure
Where is the aileron trim indicator located?
Pilots control column
How many degrees of bank are the flap manoeuvering speeds based on before initial buffet is encountered?
40°
What condition in addition to both truck tilt sensors indicating ground, is required for automatic speedbrake extension when the speedbrake lever is armed?
Both thrust leavers at Idol
What is the function of the flap load relief system on the B767–300?
If Flap speed placard limit is exceeded with the flaps in the 25 or 30 position, the flaps automatically retract to position 20
Which hydraulically powered rudder actuator is automatically depressurised when the RUDDER RATIO light is illuminated?
The left actuator
What does the stab trim light during trimming indicate?
Stabiliser trim is moving at half of the normal rate
If the speed brake lever is not armed for the spoiler deployment, what will the spoiler do on landing?
Only deploy automatically if reverse thrust is used
Which hydraulic systems power stabiliser trim?
Left and centre
Which hydraulic system operates the flaps?
Centre
What maybe indicated when the aileron lockout light comes on while accelerating?
One or both of the outboard ailerons failed to lock out
Why should the speed brake lever be moved from ARMED to the DOWN detent if the AUTO SPDBRK light illuminates?
To prevent inadvertent speed brake extension in flight. Speed brakes must be manually deployed upon landing
What is the function of the rudder ratio system?
Decreases maximum rudder pedal inputs from the pilot to reduce rudder deflection with increasing air speed
Which hydraulically powered rudder actuator is automatically depressurised when the RUDDER RATIO light is illuminated?
Left
What is indicated by an illuminated SPOILERS light and SPOILERS EICAS message?
One or more spoiler panels has failed to operate
Which hydraulic systems power the left and right yaw dampers respectively?
Centre and left
What action can be taken to possibly regain full stabiliser trim rate when the stab trim light illuminated?
Trim with alternate stabiliser trim
What systems must be available to the yaw dampers to pass yaw damper test?
One aligned IRS and hydraulic power for the system tested
During normal operation, at what flap position do the leading edge slats extend to the landing position?
25
What is indicated by the UNSCHED STAB TRIM light?
Stabiliser movement without a trim signal (possible trim run away) or the stabiliser is being trimmed in the opposite direction to the autopilot
What overrides all other stabiliser trim systems inputs?
Alternate stabiliser trim switches
What is the stabiliser trim rate during autopilot operation?
Half the electric trim rate
How can stabiliser movement be stopped if a trim run away is detected?
Move the control column in the opposite trim direction
What does the RUDDER RATIO light illuminated in-flight mean?
Control inputs to the rudder are not being correctly modified. Limited import should be used
What is indicated when the right yaw damper switch has an ON indication and the INOP light illuminated?
Fault exists in the system
How are the flaps operated after a centre hydraulic system failure?
The alternate system operates the flaps with electric motors
Is normal flap load relief available while utilising the alternate flaps system?
No
What happens when moving the flap lever from UP to the 1 position?
Only the leading edge slats extend
On an aircraft with winglets, when does the speed brake load alleviation system activate?
Flaps up,
Aircraft weight is above 340,000lbs
Airspeed is greater than 320 knots
The pitch enhancement system operates when?
Operates automatically with the loss of centre and left hydraulic system pressure
An off flag in the stabiliser position indicator means?
Stabiliser trim indicator failure
What happens when take off power is applied and stab trim is out of the green band?
CONFIG warning light illuminates
EICAS stabiliser warning appears
Master warning light illuminates
Siren sounds
What do the STAB TRIM CUTOUT switches do when placed to the CUTOUT position?
Remove electrical power to the stab trim
Shut off respective hydraulic power to the stab trim
Enables use of manual or alternate trim switches
How are the control wheel stabiliser trim switches affected when multiple autopilots are engaged, as in autoland?
They are inhibited
The pitch enhancement system (PES) is an automatic feature to provide a third power source for stabiliser trim in the event what system fails?
Left and centre hydraulic systems
At higher airspeeds which wing components are locked out?
Outboard ailerons
What is indicated when the aileron lockout light comes on at low airspeeds?
One or both of the outboard ailerons failed to unlock
What is/are the normal landing flap setting(s)?
Flaps 25 and 30
Is there any asymmetry protection in alternate flap mode?
Trailing edge flap protection is not available in alternate mode
