  1. Primary Flight Controls
    • Ailerons
    • Elevator
    • Rudder
    • (manually operated, mechanical linkages)
  2. Secondary Flight Controls
    • Aileron trim (entire surface moves)
    • Elevator trim tab
    • Rudder trim tab
    • Trim Aid Device (TAD)
    • (electromechanically operated & controlled)
  3. Aileron system components
    • Left/right aileron
    • 2 control sticks
    • Interconnect tube
    • Push-pull rods
    • Bellcranks
  4. Elevator system components
    • Elevator
    • 2 control sticks
    • Interconnect tube
    • Bellcranks
    • Elevator cables
    • Downsprings
    • Bobweight
  5. Rudder system components
    • Rudder
    • 2 Sets of rudder pedals
    • Rudder cables
    • Pulleys
    • Bellcranks
    • Tie rods
    • Centering springs
  6. Rudder peddal hand crank moves peddals
    7" forward and back
  7. Aileron/Elevator trim location
    • On control stickstick
    • Rear cockpit has priority
  8. Rudder trim
    • Switch on PCL
    • Rear cockpit has priority
  9. Trim interrupt
    • Rapid disconnect of all trim systems
    • Press and hold to stop all; release to restore power to trim actuators, TAD stays off however
    • TRIM OFF and TAD OFF annunciators illuminate while button held
  10. Trim position indicator
    Green marks are takeoff settings
  11. Trim Aid Device (TAD)
    • Assist pilot in directional control - Rudder
    • Switch is in front cockpit only
    • Pre-calculated takeoff setting; no further adjustments until 80 KIAS
    • TAD will reset to takeoff setting upon landing or touch and go
  12. TAD takes inputs from:
    • Pitch rate
    • Altitude
    • Airspeed
    • Torque (engine)
  13. Gust Lock
    Lock ailerons/rudder to neutral position & elevator nose down
  14. Hydraulics
    compressed fluids
  15. Pneumatics
    compressed gasses
  16. Hydraulic system pressurized to
    3000 +/- 120 psi
  17. Hydraulic system controls
    • Landing gear and main landing gear inboard doors
    • Flaps
    • Speed brake
    • Nose wheel steering
  18. Visual check of hydraulic system (green bar shows)
    • FULL AC = (Accumulator Charged)
    • FULL AD = (Accumulator Discharged)
  19. Source of hydralic pressure
    engine driven pump
  20. Engine driven pump
    • Distributes pressure to reservoir in the power package
    • Then pressure moves onward to the selector Manifold
    • Pressure also moves to the emergency system
  21. Hydraulic system can be used once pressure reaches...
    1800 psi
  22. Step down piston returns hydraulic fluid at...
    50 psi
  23. Pressure relief valve operates at...
    3250-3500 psi
  24. EMER LDG GR HANDLE
    • closes power package slide valve to isolate main hydraulic system
    • release emergency accumulator pressure
    • Isolates selector manifold but NWS can still receive pressure
  25. Selector Manifold has __ electric selector vavles
    • (5)
    • Landing gear
    • Inboard doors
    • Speed brake
    • Flaps TO
    • Flaps LDG
  26. Hydraulic pressure displayed in what 2 ways
    • Analog
    • Digital
  27. Hydraulic pressure display green range
    2880-3120 psi
  28. Hydraulic pressure display white range
    1800-2880 & 3120-3500 psi
  29. Hydraulic pressure display amber range
    1700-1800 & 3500-3600 psi
  30. 2 Master Caution annunciators associated with Hydraulics
    • HYDR FL LO = fluid level in reservoir drops below 1 qt
    • EHYD PX LO = pressure in emergency accumulator drops below 2400 +/- 150 psi
  31. Emergency hydraulic system used for
    • Primary hydraulic system failure
    • Engine failure
    • Battery bus failure
  32. Emergency hydraulic system allows for
    • One time lowering of landing gear, gear doors, and flaps
    • Make sure to put landing gear handle down first
  33. Emergency landing gear pressure release valve at
    3500psi
  34. Max speed for landing gear operation
    150 KIAS
