B777 Flight ControlsHome / Quiz Page / B777 Flight Controls Boeing 777 Flight Controls Boeing 777 Flight Controls 1 / 15 When do the control wheel stabilizer trim switches control stabilizer movement directly? Only on the ground. During engine out go-arounds. All the time. All the time. 2 / 15 When do the PFCs make self-test? After hydraulic system depressurization. After hydraulic system shutdown (HYD PRESS SYS L+C+R). After the "PRIMARY FLIGHT COMPUTERS" EICAS message is displayed. After hydraulic system pressurization. 3 / 15 Which spoilers are available as speedbrakes (secondary and direct modes)? Spoilers 1-7 Spoilers 4,11 None. Speedbrakes are disabled. Spoilers 5,10 4 / 15 What control do the flaperons and ailerons provide? Yaw control assisted by the rudder. Roll control assisted by asymmetric spoilers. Increased wing lift and decreased stall speed. Pitch control assisted by a movable horizontal stabilizer. 5 / 15 Which of the following is not a stall protection feature? Stab trim is inhibited in the nose up direction at approximately the minimum manoeuvring speed. The pilot must apply continuous aft column force to maintain airspeed below the manoeuvring speed. Use of alternate pitch trim levers reduces the column forces below the minimum manoeuvring speed. The out-of-trim forces increase above normal for a condition above the minimum manoeuvre speed. 6 / 15 Which trim control is inhibited when the autopilot is engaged? Control wheel pitch trim switches. Alternate control pitch trim. Alternate pitch trim levers. Trim control pitch 7 / 15 What is the meaning of the EICAS advisory message STABILIZER CUTOUT? Both stabilizer cut-out switches are in the CUTOUT position. Stabilizer asymmetry compensation is inoperative. The centre stabilizer control path is inoperative One stabilizer cut-out switch is in the CUTOUT position. 8 / 15 Automatic speed-brake operation is provided for which flight control system modes? Secondary. Normal. Direct. All flight control modes. 9 / 15 Which of the following are NOT stall protection features? In landing configuration, leading slats move to gapped position. The autothrottle advances to maintain minimum airspeed. The autothrottle disconnects. Stick shaker activates. 10 / 15 Where - and when - is the stabilizer "green band" displayed? Only during landing, on CDU. Always on EICAS Only on the ground, on pitch trim indicators. Only in flight, on control wheel. 11 / 15 Do the ailerons increase lift for takeoff? No, the ailerons assist roll control only during high speed flight. No the ailerons are used only at high speed Yes the ailerons move down with flaps 5, 15 and 20. Yes the ailerons move down with flaps 15 and 20. 12 / 15 What happens when the stabilizer signal is not present or is invalid? The green band on the indicator turns amber The green band and the pointer are not displayed The CDU displays the VERIFY TRIM message in the scratchpad The EICAS message STAB GREENBAND displays 13 / 15 Which of these flight control surfaces droop when the trailing edge flaps extend? Flaperons and slats. Krueger flaps and slats. Slats only. Flaperons. 14 / 15 When are pitch trim changes required with the 777 'fly-by-wire' system? For all configuration changes. When the landing gear is extended. When thrust is changed. During airspeed changes only. 15 / 15 Which spoilers will be locked out in secondary and direct modes? Spoilers 1 to 7 Spolers 5 and 10 Spoilers 8 to 14 Spoilers 1 and 14 Your score is
