Q
AILERONS
- Mechanical
- Trim tab on left aileron (electro-mechanical)
- Gear tab both ailerons
- +/-15 deg
- Aileron disconnect on pilot yoke
- Mechanically disconnects pilot’s yoke only (control via roll spoilers)
- Control via MFS through RVDTs
- Eddy current dampener -prevent sudden jerk
- Q-Feel
- Auto-pilot actuator
- Gust lock – throttle and aileron

Q
ELEVATOR
- Hydraulic boosted (hydro mechanical)
- Both hydraulic systems
- Manual reversion
- 95lbs differential force to separate
- Q-Feel – hyd unit acts against artificial feel as speed increases – prevent overstress
- Trim 1 jack screw two electric motors, alternate half speed
- Captain trim overrides copilot

CONTROL CHECK
- Carry out when flaps position – 10 or 20
- Roll left, brakes out L 35 R 10, roll right, retract brakes, neutral (if no flaps opposite side no 10)
- CAS logic pitch only to register check. Forward then aft slowly.
