226
Describe how the STAB trim cutout switches work when in the 'auto' position.

229
What is the purpose of the yaw dampeners?
Provide turn coordination
Improve lateral and directional stability
230
How does the aileron lockout system work? What is its purpose?
Permits full travel of the outboard ailerons at low airspeeds, and locks the outboard ailerons in the neutral position at high airspeeds, preventing over-controlling
