The stabilator on the S-70 series receives inputs from:
1. Airspeed - To keep the fuselage level in cruise and to reduce the pitch attitude during deceleration to a hover.
2. Lateral Acceleration – To keep the pitch attitude level during sideslips (counteract the canted tail)
3. Pitch Rate – To enhance maneuver stability
4. Collective position – To reduce the tendency for pitch attitude changes with collective changes
I think I hit them all. It works really hard in turbulance.
