Flight Controls Flashcards
What are the ailerons controlled by?
Power Control Units (PCU)
What is manual reversion?
A loss of Hydraulic system A and B, pilots control wheel can move ailerons
Can you use aileron trim with the autopilot engaged?
Prohibited
At what point is spoiler deflection initiated?
Approx more than 10 degrees of control wheel displacement
The horizontal stabilizer is controlled and positioned by:
A single electric trim motor
During normal operations, which hydraulic system does the main yaw damper use?
Hydraulic system B
When will the SPEED BRAKES EXTENDED light illuminate on flight?
When SPEED BRAKES are extended while in landing configuration( flaps more than flaps 10) or below 800 feet RA
During landing, the auto speed brake system operates under what conditions?
SPEED BRAKE lever ARMED
SPEED BRAKE ARMED light illuminated
Thrust levers idle
Main landing gear wheel spin up ( more than 60 knots)
Landing gear strut compression
Radio altimeter less than 10 feet
If speed brake lever is in DOWN position during landing or RTO, auto speed brake system works how?
Main landing gear wheel spin up (more than 60 knots)
Thrust levers idle
Reverse thrust levers positioned for reverse thrust
On the ground, the SPEED RAKES EXTENDED light illuminates for what reason?
When speed brake lever is in the DOWN position and the ground spoilers are not stowed?
Which hydraulic system normally operate flaps?
Hydraulic system B
What are the normal flap position for landing?
15
30
40
LE FLAPS TRANSIT light illuminates for what conditions?
Any LE device is in transit
LE device not in programmed position
ALE slat skew condition exists ( slats 2 through7)
Flap load relief limits flap setting automatically for over speed conditions. What flap settings will flap load relief limit flaps?
Flap 30 and 40
From 40 to 30 if speed of 163 knots is exceeded
From 30 to 25 if 176 knots exceeded
Which leading edge devices don’t have skew detection?
Slats 1 and 8
Leading edge flaps
What happens when an uncommanded motion of the flaps slats is detected?
The TE drive unit is shutdown and the system will only operate in Alternate mode
Moving the FLT CONTROL switch to STBY RUD does what?
Activates standby hydraulic system pump
Opens the standby rudder shutoff valve
Illuminates the STBY RUD ON light
Which flight controls are mechanically controlled during manual reversion?
Ailerons
Elevator
The yaw damper system is capable of providing what features?
Gust damping
Dutch roll prevention
Turn coordination
Which hydraulic system controls yaw damper?
Hydraulic system B
Slats will extend to the full extend position when what happens with flaps?
Flap lever is beyond flaps 5
Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens switch is in STBY RUD position?
Activates standby hydraulic system pump/ opens standby rudder shutoff valve to pressurize standby rudder power control unit (PCU)
Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens when switch is in off?
Closes flight control shutoff valve isolating ailerons, rudder, elevator from the associated hydraulic system pressure
Flight Control Panel: FLIGHT CONTROL switches system A & B. What happens when switch in ON position?
Normal operating position
Flight Control Panel: FLIGHT CONTROL system A & B LOW PRESSURE lights illuminate for what reasons?
- Indicates low hydraulic systems (A or B) pressure to ailerons, elevators, rudder
- Deactivated when associated FLIGHT CONTROL switch is positioned to STBY RUD and standby rudder shutoff valve opens
