SY109 Flight Controls Flashcards
This flashcard deck was created using Flashcardlet's card creator
How are the secondary flight controls operated?
Electromechanically
The 4 secondary flight controls are:
Aileron trim surfaces
Elevator trim tab
Rudder trim tab
Trim Aid Device (TAD)
The components of the ailerons are (5)
Left and right aileron Two control sticks Interconnect tube Push-pull rods Bellcranks
Aileron deflection trailing edge travel is limited to ____ up and ____ down
20° up
11° down
The elevator system consists of (7):
The elevator Two control sticks Push-pull rods Interconnect tube Bellcranks Elevator cables Down springs Bobweight
What is the purpose of the bobweight?
Provides heavier stick force whenever G-loading is increased. Heavier stick force helps enhance control feedback to help prevent overstressing of the airframe. Heavy metal plate attached to the base of the front control stick.
Maximum travel of the elevator trailing edge is:
18° up
16° down
The rudder system consists of (7):
The rudder Two sets of rudder pedals Rudder cables Pulleys Bellcranks Tie rods Centering springs
Adjustment range for the rudder pedals ___ inches forward and aft
7 inches
Rudder travel is limited to a maximum of _____° left and right
24º
In the event of conflicting trim inputs, the ____ cockpit has priority
rear cockpit
The trim circuit breakers are on the ________ bus panel
Battery Bus
Maximum aileron trim displacement is ____º up and down
Maximum elevator trim displacement is ____º up and ____º down
Maximum rudder trim displacement is ____° left and right
6° up and down
5.5° up and 22° down
9° left and right
The Trim Aid Device (TAD) calculates input to the rudder trim based on (4):
Pitch rate
Altitude
Airspeed
Engine torque
The TAD automatically sets the rudder takeoff and makes no further adjustments until > _____ knots and _________
> 80 knots and weight off wheels
Pilot control of the aileron trim is accomplished by movement of an electromechanical trim tab installed in the ________ of the wing.
Center
How are the ailerons mass balanced and what function does this perform?*
Small weights are placed along the leading edge oat the point where the ailerons pivot. These weights ensure the center of gravity for each aileron is at the pivot point.
How is electrical power provided to operate the aileron and elevator trim system?*
Through the AIL/EL TRIM circuit breaker on the BATTERY BUS
