Primary Flight Controls
- Ailerons
- Elevator
- Rudder
- (manually operated, mechanical linkages)
Secondary Flight Controls
- Aileron trim (entire surface moves)
- Elevator trim tab
- Rudder trim tab
- Trim Aid Device (TAD)
- (electromechanically operated & controlled)
Aileron system components
- Left/right aileron
- 2 control sticks
- Interconnect tube
- Push-pull rods
- Bellcranks
Elevator system components
- Elevator
- 2 control sticks
- Interconnect tube
- Bellcranks
- Elevator cables
- Downsprings
- Bobweight
Rudder system components
- Rudder
- 2 Sets of rudder pedals
- Rudder cables
- Pulleys
- Bellcranks
- Tie rods
- Centering springs
Rudder peddal hand crank moves peddals

7" forward and back
Aileron/Elevator trim location
- On control stickstick
- Rear cockpit has priority
Rudder trim
- Switch on PCL
- Rear cockpit has priority
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
Trim position indicator

Green marks are takeoff settings
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
TAD takes inputs from:
- Pitch rate
- Altitude
- Airspeed
- Torque (engine)
Gust Lock

Lock ailerons/rudder to neutral position & elevator nose down
Hydraulics

compressed fluids
Pneumatics

compressed gasses
Hydraulic system pressurized to

3000 +/- 120 psi
Hydraulic system controls
- Landing gear and main landing gear inboard doors
- Flaps
- Speed brake
- Nose wheel steering
Visual check of hydraulic system (green bar shows)
- FULL AC = (Accumulator Charged)
- FULL AD = (Accumulator Discharged)
Source of hydralic pressure

engine driven pump
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
Hydraulic system can be used once pressure reaches...

1800 psi
Step down piston returns hydraulic fluid at...

50 psi
Pressure relief valve operates at...

3250-3500 psi
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
Selector Manifold has __ electric selector vavles
- (5)
- Landing gear
- Inboard doors
- Speed brake
- Flaps TO
- Flaps LDG
Hydraulic pressure displayed in what 2 ways
- Analog
- Digital
Hydraulic pressure display green range

2880-3120 psi
Hydraulic pressure display white range

1800-2880 & 3120-3500 psi
Hydraulic pressure display amber range

1700-1800 & 3500-3600 psi
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
Emergency hydraulic system used for
- Primary hydraulic system failure
- Engine failure
- Battery bus failure
Emergency hydraulic system allows for
- One time lowering of landing gear, gear doors, and flaps
- Make sure to put landing gear handle down first
Emergency landing gear pressure release valve at

3500psi
Max speed for landing gear operation

150 KIAS
