Flight Controls Flashcards
- In normal operation, most A330 flight controls are:
a. electrically controlled and hydraulically actuated
b. electrically controlled with mechanical back-up control and hydraulically actuated
c. electrically controlled and hydraulically actuated with mechanical reversion capability
a. electrically controlled and hydraulically actuated
- All A330 flight controls are actuated by hydraulic servos which are controlled by computers:
a. or cables
b. but the stabilizer and rudder trim may also be controlled by cables
c. but the stabilizer and rudder servos may also be controlled by cables
c. but the stabilizer and rudder servos may also be controlled by cables
- The side stick inputs results in adjusting:
a. the pitch and roll only
b. the pitch, roll and yaw (for turn coordination)
c. the elevators, ailerons and nosewheel steering (during ground operation)
b. the pitch, roll and yaw ( for turn coordination)
- Pitch control is provided by:
a. two independent elevators and a Trimmable Horizontal Stabilizer
b. Two inter-connected elevators and a Trimmable Horizontal Stabilizer
c. Two inter-connected elevators with trim tabs and a Trimmable Horizontal Stabilizer
a. two independent elevators and a Trimmable Horizontal Stabilizer
- The ailerons are each actuated by:
a. Two hydraulic servos, each powered by one of two hydraulic systems
b. Two hydraulic servos, each powered by one of three hydraulic systems
c. Three hydraulic servos, each powered by one of three hydraulic systems
b. Two hydraulic servos, each powered by one of three hydraulic systems
- The speedbrake surfaces are:
a. spoilers 2 through 4
b. spoilers 2 through 5
c. spoilers 1 through 6
c. spoilers 1 through 6
- The autopilot function is lost in case of:
a. PRIM 1 + 2 failure with SEC 1 + 2 available
b. PRIM 1 and 2 SEC 1 + 2 failure
c. PRIM 1 + 2 + 3 failure with Sec 1 + 2 available
c. PRIM 1 + 2 + 3 failure with Sec 1 + 2 available
- Each PRIM provides:
a. Normal control laws and characteristics speed computations only
b. Normal, Alternate, Direct Laws, speed brakes and ground spoilers control logic, characteristics speed computations
c. Normal and alternate laws only, speed brakes and ground spoilers control logic
b. Normal, Alternate, Direct Laws, speed brakes and ground spoilers control logic, characteristics speed computations
- Each SEC provides at least:
a. Direct control laws, rudder trim, yaw damper, rudder and rudder pedals travel limits
b. Direct control laws, speed brakes and ground spoilers control logic
c. Alternate control laws, characteristic speeds computation
a. Direct control laws, rudder trim, yaw damper, rudder and rudder pedals travel limits
- For elevators control, each servo jack has:
a. 2 control modes: active and damping
b. 2 control modes: active and centering
c. 3 control modes: active, damping and centering
c. 3 control modes: active, damping and centering
- On one control surface if an active servo jack fails:
a. the related surface is lost
b. the damped servo jack on the same surface becomes automatically active
c. the surface deflection is reduced
b. the damped servo jack on the same surface becomes automatically active
- Normal pitch control uses:
a. PRIM 1, the elevator green hydraulic jacks and the number 1 THS electric control motor
b. PRIM 1, the elevator green hydraulic jacks, and the number 2 THS electric control motor
c. PRIM 2, the elevator blue and yellow hydraulic jacks and the number 2 THS electric control motor
a. PRIM 1, the elevator green hydraulic jacks and the number 1 THS electric control motor
- If neither PRIM 1 or PRIM 2 are available, pitch control is transferred to:
a. SEC 2 for elevator control and PRIM 3 using the number 2 electric motor for THS control
b. SEC 1 for elevator control and PRIM 3 using the number 3 electric motor for THS control
c. PRIM 3 for elevator control and SEC 2 using the number 2 electric motor for THS control
b. SEC 1 for elevator control and PRIM 3 using the number 3 electric motor for THS control
- If all three PRIM computers are not available:
a. the THS is controlled by the manual pitch trim wheel only
b. the THS is controlled by the manual pitch trim wheel and the number 2 electric motor
c. the THS is controlled by the manual pitch trim wheel and the number 3 electric motor
a. the THS is controlled by the manual pitch trim wheel only
- Aileron droop:
a. occurs when the slats and flaps are extended
b. occurs when flaps are extended and is single droop setting
c. occurs when the flaps are extended and is a variable droop setting
c. occurs when the flaps are extended and is a variable droop setting
- When the RAT is extended to recover hydraulic or electric power, the servo jacks that revert to damping mode control:
a. the outboard ailerons
b. the inboard ailerons
c. spoiler 1 to 6
a. the outboard ailerons
- Loss of hydraulic power to one of the single spoiler servos will cause that surface to:
a. retract
b. remain at the existing deflection or less if pushed down by aerodynamic forces
c. extend fully
b. remain at the existing deflection or less if pushed down by aerodynamic forces
- According to these cockpit indications the ground spoilers are: (speed brake lever pulled,
white marking visible and ECAM flight control page show a retracted spoiler)
a. armed and extended
b. armed and not extended
c. unarmed and not extended
b. armed and not extended
- The speed brake lever is not ARMED and ECAM shows a retracted spoilers. According to these cockpit indications, when this aircraft lands the ground spoilers will:
a. extend automatically on touchdown
b. extend when the pilot selects reverse on at least 1 engine (other engine at idle).
c. not extend, no matter what the pilot does with thrust levers
b. extend when the pilot selects reverse on at least 1 engine (other engine at idle).
- With yaw damping or turn coordination functions:
a. you can “feel” the inputs with rudder pedal movement
b. feedback is provided only when the autopilot is off
c. no feedback to the rudder pedals are provided
c. no feedback to the rudder pedals are provided
