Flight Controls Flashcards
(26 cards)
QWhat is the function of the AUTO CENTER button on the Trim panel?
A.It will center the Rudder Trim when pushed momentarily.
Q.In flight, what do the flight spoilers do?
A.Work with the ailerons to improve roll response.
Q.What are the four Flight Control modes?
A.Normal, Alternate, Direct and Backup
Q.If the airplane initiates the Emergency Descent Mode, it will automatically level off at 15,000 feet. If this altitude is too low, what must be done to change the level off altitude?
A.Disengage the autopilot and select the appropriate altitude and Flight Director Mode in the Flight Guidance Panel.
Q.The FLCH (Flight Level Change) mode is selected on the guidance panel while the Autopilot and Autothrottle are engaged. How is the airspeed controlled?
A.Pitch is used to control airspeed while the autothrottle controls thrust.
Q.Which Flight Director Mode is available during Climb in VNAV mode?
A.VFLCH only.
Q.When will the Flight Control System perform the System Power-On Self Test (SPOST)?
A.During preflight after selection of the EBHA and UPS to ON.
Q.If the airplane initiates Emergency Descent Mode it will level off at 15 000 ft. If this altitude is too low, how can the crew change the level‑off altitude?
A.Disengage the autopilot and use the Flight Guidance Panel to select the desired altitude and Flight Director mode.
Q.Which flight control(s) does the autopilot have authority over?
A.Aileron and Elevator
Q.Display Unit (DU) #4 fails in flight showing a black screen. What, if anything, can be done to restore the FO’s PFD?
A. The PFD reverts to DU#3 automatically.
D.During cruise in the Normal flight control mode, what moves when pitch trim is applied?
A.Initially the Elevators. The Elevators will then be offloaded by the Stabilizer
Q.In which Flight Control mode is the Autopilot available?
A.Only in the Normal Flight Control mode.
Q.When will the Flight Control System perform the System Power-On Self Test (SPOST)?
A.During preflight after selection of the EBHA and UPS to ON1
Q.In which Flight Control Modes will the Yaw Damper be available?
N.Normal, Alternate, Direct and Backup
Q.What speed gain is used to determine the flight control surfaces deflection when the Flight Control System is not in Normal mode?
A. Low Speed gain (250 KCAS) and High Speed gain (340 KCAS).
Q.Where can the individual WOW status be observed?
A. On the Flight Control synoptic.
Q.What is the function of the GPWS/GND SPLR FLAP ORIDE switch?
A. It will enable the ground spoiler logic irrespective of the Flap position and it will inhibit the Too Low Flap warning.
Q.What will occur if landing at flap setting of 20° or less and the GPWS/FLAP OVERRIDE switch is not selected to ON?
A. GPWS will announce TOO LOW FLAPS, and the ground spoilers will not deploy based on wheel spin.
Q.What speed gain is used when FCS is not in Normal mode?
A.Low Speed gain (250 KCAS) and High Speed gain (340 KCAS).
Q.What does it mean when HOLD is indicated on the PFD?
A. THE AT Servos are de-energized to prevent unwanted thrust reductions
Q.What is the purpose of the Landing Controllability Check?
A.To verify the approach speed at which the aircraft has sufficient controllability for the approach and landing
Q.The Primary Flight Control System downgrades to the Direct Mode. What would be a typical reason for this to occur?
A. Flight Control Computer (FCC) problems.
Q.FCS is in Backup Mode. How can you apply pitch trim?
A.Only by using the Backup Pitch Trim switch on the pedestal.
Q.Can the nose wheel be steered through the rudder pedals?
A.Yes.
