During normal primary yaw damping, why are both Stall Management Yaw Damper (SMYD) computers required even though SMYD 1 generates the primary rudder command?, SMYD 2 supplies electrical power to the main rudder Power Control Unit (PCU), SMYD 1 compares its yaw-damping calculation with SMYD 2 before commanding rudder movement, SMYD 2 independently commands the rudder and SMYD 1 provides only monitoring, Built-In Test Equipment (BITE) is selected on a Stall Management Yaw Damper (SMYD) computer while the engines are operating. Which condition permits the BITE function to remain available?, Flaps up with computed airspeed below 60 knots, Flaps not up with computed airspeed below 80 knots, Either engine below 50 percent N1 regardless of airspeed, Before autopilot engagement, the Flight Control Computer (FCC) detects hydraulic pressure already present at an autopilot actuator. What should the engage-interlock logic do?, Permit engagement because hydraulic pressure confirms actuator availability, Prevent engagement because actuator pressure switches must initially indicate no hydraulic pressure, Engage in Control Wheel Steering mode only until actuator pressure reduces, The Maneuvering Characteristics Augmentation System (MCAS) is operating at elevated angle of attack. Which flight-crew input is specifically designed to stop and reverse the commanded stabilizer movement without selecting the stabilizer trim cutout switches?, Main electric stabilizer trim switch input, Autopilot disengage switch input, Flight Director mode-selection input, During takeoff, one or both Flight Director switches are OFF. Under which condition can Flight Director guidance nevertheless appear automatically in the pop-up mode?, A Takeoff/Go-Around switch is pressed and airspeed is above 80 knots, The airplane passes 400 feet radio altitude with the autopilot disengaged, The autothrottle enters Throttle Hold mode above 60 knots, Which statement correctly distinguishes the Speed Trim System from the Mach trim function?, Speed Trim operates only with the autopilot engaged, whereas Mach trim requires manual flight, Both functions are inhibited whenever either Flight Director is selected ON, Speed Trim operates only with the autopilot disengaged, while Mach trim can operate with the autopilot engaged or disengaged, During a dual-channel Category IIIB automatic landing approach below 1,500 feet radio altitude, one failure degrades the system from fail-operational to fail-passive capability. What indication is expected?, LAND 3 remains displayed and NO AUTOLAND appears immediately, LAND 2 is displayed and NO LAND 3 appears on the engine indicating display, Both autopilots immediately disengage and NO AUTOLAND appears, A maintenance engineer intends to erase Digital Flight Control System (DFCS) fault history after troubleshooting an intermittent defect. According to the training material, when is complete fault-history erasure normally appropriate?, After every successful verification test, Whenever no current faults remain after a flight, Primarily after installing a new Flight Control Computer or permanently transferring one from another aircraft, During takeoff, the Autothrottle enters Throttle Hold mode. What is the key functional difference between Throttle Hold and ARM mode?, Throttle Hold removes power from the Autothrottle Servo Motors, while ARM retains servo power but prevents the control logic from moving the thrust levers, Throttle Hold retains servo power but freezes the Flight Management Computer thrust target, while ARM removes servo power, Both modes remove servo power, but only ARM permits manual thrust-lever movem, During Autothrottle Built-In Test Equipment (BITE), a technician wants to verify the Captain and First Officer Takeoff/Go-Around switches and both thrust-lever disengage switches. Which interactive test provides these checks?, Servo Motor Test, Input Discretes Test, Range Check Test
