Fltct Flashcards
On the ground above 60kts groundspeed, the flight control system attempts to maintain a yaw rate near zeo by appyling rudder input. This function is only available in ____.
The NORMAL flight control mode.
With a coplete loss of flight control signaling, the ____ must be used to move the stabilizer.
Alternate pitch trim switches
The flaps and slats are driven:
Hydraulically in the PRIMARY mode only

Middle
On the ground, all spoiler panels extend if both reverse thrust levers are raised to the reverse idle detent.
A. True
Which of the following is true when the flight control sytem is operating is secondary mode?
Autopilots and envelope protections are not available.
With flight controls operating in the direct mode, which of te following components of the primary flight control system are inoperative?
Primary flight computer (PFCs).
Automatic speedbrake extension is provided for a rejected takeoff.
A. True
Thw autopilot sends signals:
Directly to the PFCs.
The autopilot is available in:
NORMAL flight control mode only.
Whe the flaps and slats are in the PRIMARY mode, uncommanded motion will:
Cause the flap or slats to transfer to the SECONDARY mode.
When operating with th slats in the SECONDARY mode and positioned to the fully extended position, if the airspeed exceeds 225 knots:
B. LOAD RELIEF will be displayed on the EICAS.
C. The slats will retract to the middle position.
The primary f;ight control computers (PFCs) cannot override a pilot command.
A. True
The flaps and slats in the SECONDARY mode are controlled seperately and can be positioned by hydraulic or electric pumps.
A. True
How can the pilot place the aircraft into the SECONDARY flight control mode?
You cannot, SECONDARY selection occurs automatically.
In the NORMAL flight control mode, yaw control attempts to maintain zero yaw rate due to engine failure when above _____?
60kts groundspeed and aircraft on the ground
Disconnecting the primary flight control computers (PFC’s) places the aircraft _____.
In the DIRECT mode.
Wheel to rudder cross-tie is available in which mode(s)?
A. Secondary
C. Direct
The three modes of the Primary Flight Control System are:
NORMAL, SECONDARY, DIRECT
With a total hydraulic failure, Pitch and Roll control is still available:
electrically using the control wheel and either primary or alternate pitch trim.
After landing, tje flight control system automatically self test:
with flaps and speedbrakes retracted and groundspeed less than 30kts
Why is the B787 provided with an elctrical flight control backup system?
B. In case of a complete hydraulic loss.
During takeoff, the rudder becomes aerodynatically effective at:
approximately 60 knots.
When autopilot is not engaged, when is manual trimming necessary?
B. For airspeed changes.
In the NORMAL mode, pitch trim operates the in same manner on the ground as it does in flight.
B. False
The alternate pitch trim switches may be used with the autopilot engaged to correct for minor airspeed changes.
B. False
The stabilizer green band is calculated by:
B. FMC inputs of CG, and gross weight.
The EICAS message STAB GREENBAND is displayed when:
A. The nose gear pressure tranducer and greenband data disagree.
C. Either nose gear transducer fails.
If BOTH the L2 and R2 stabilizer control switches are placed to CUTOUT while in the NORMAL flight control mode:
Pitch trim is still available through the trim switches.
The autothrottles must be ____ to support stall protection.
Armed
When the pitch mode is FLCH or TOGA the autothrottles will not automatically engage to support stall protection.
A. True
The ailerons are:
Locked out during high speed flight.
Each spoiler pair is dedicated to the same hydraulic system, therefore, symmetric operation is maintained in the event of hydraulic system failure.
A. True
Some of the benefits of the fly-by-wire design are:
A. Increased fuel economy.
B. Enhanced handling quantities.
C. Reduced pilot workload.
When is the slat auto gap function available?
B. Only in the primary mode and at flaps 1, 5, 15, and 20..
Which of the following are limitations on the use of speed brakes?
D. Do not use the speed brakes inflight below 1000 feet.
The B787 has a single rudder with the lower portion having a hinged section that deflects twice as far to provide additional yaw authority.
B. False
The Wheel to Rudder Cross-Tie system operates in conjunction with TAP and is effective both on the ground and in the air
B. False
If the flap placard speed is exceeded with flaps in the ____ position, LOAD RELIEF is displayed and the flaps automatically retract to a position appropriate for the airspeed.
B. 15 through 30
Which flight control surfaces are locked out during high- speed flight?
Ailerons
The yaw control function for thrust asymmetry :
Is only available in the Normal flight control mode.
Which of the following functions are available in the Secondary Mode?
A. Wheel to rudder cross-tie
What happens when a a roll control wheel input causes the bank angle to exceed 35 degrees?
B. The PFD bank indicator turns amber.
Automated yaw and roll control for engine failure, crosswind, or turbulance is an integral part of the flight control system.
A. True
Tailstrike protection can be overriden by pilot input.
A. True
Auto drag operates only on an electric or FMC generated glidepath.
B. False
Wheel to rudder cross tie is not provided in hte Normal flight control ode because the flight control system automatically controls sideslip and fin loads.
A. True
Rudder trim is automatic in all flight phases in the Normal flight control mode, including during engine failure.
A. True
After landing during a single engine approach, an applied automatic or manual trim inputs are zeroed after landing.
A. True
The speedbrakes automatically retract in the air when either throttle is advanced 90% full travel.
A. True
