Flight Controls Flashcards
The stabilizer and rudder can also be
mechanically-controlled
regardless of the pilot’s input, the computers will prevent excessive maneuvers and exceedance of the safe envelope in pitch and roll axis. However, as on conventional aircraft, the _______ has no such protection
rudder
Stabilizer = Electrical for ________or ______ control ________ for manual trim control
normal / alternate / Mechanical
Rudder = _______, however control for yaw damping, turn coordination and trim is _________.
Mechanical / electrical
_______flight control computers process pilot and autopilot inputs according to normal, alternate, or direct flight control laws
Seven / 2 ELACs (Elevator Aileron Computer) For : Normal elevator and stabilizer control. Aileron control. 3 SECs (Spoilers Elevator Computer) For : Spoilers control. Standby elevator and stabilizer control. 2 FACs (Flight Augmentation Computer) For : Electrical rudder control.
Two elevators and the Trimmable Horizontal Stabilizer (THS) control the aircraft in pitch. The maximum elevator deflection is ____ ° nose up, and _____° nose down. The maximum THS deflection is ____° nose up, and _____° nose down.
30 / 17 / 13.5 / 4
One aileron and four spoilers on each wing control the aircraft about the roll axis. The maximum deflection of the ailerons is ___ °. The ailerons extend ____ ° down when the flaps are extended (aileron droop). The maximum deflection of the spoilers is ____°.
25 / 5 / 35
Speedbrake extension is inhibited, if:
‐ SEC 1 and SEC 3 both have faults, or ‐ An elevator (L or R) has a fault, or ‐ Angle-of-attack protection is active, or ‐ Flaps are in configuration FULL, Thrust levers above MCT position, or ‐ Alpha Floor activation.
The maximum speedbrake deflection in manual flight is:
40 ° for spoilers 3 and 4 20 ° for spoiler 2.
The maximum speedbrake deflection with the autopilot engaged is:
25 ° for spoilers 3 and 4 12.5 ° for spoiler 2.
ground spoilers retract:
• After landing, • After a rejected takeoff, when the ground spoilers are disarmed. • During a touch and go, when at least one thrust lever is advanced above 20 °
SHARP (Short Airfield Package) is a set of aircraft modifications allowing operations on short runway:
• An improved leading edge root fillet • A Vortex Generators on trailing edge panels
The normal flight control laws provides:
‐ Aircraft control on the 3 axis ‐ Flight envelope protection ‐ Alleviation of maneuver loads.
Protections are intended to:
• Provide maximum authority to the PF to consistently achieve the best possible aircraft performance in extreme conditions • Reduce the risks of overcontrolling, or overstressing the aircraft • Provide PF with an instinctive and immediate procedure to ensure that the PF achieves the best possible result
Flight Controls - normal law- pitch- Ground mode is a direct relationship between:
sidestick deflection and elevator deflection, without auto trim.
