I'm having a hard time understanding the correlation between the wind gusts (where are they coming from, what are they affecting) and why, in a nose left situation, the stabilator is driven down.
I keep thinking it would make sense for it to go up (e.g. left pedal, more tail rotor torque, tail up, nose down.
sideslip to pitch coupling to reduce susceptibility to gusts. When the helicopter is out of trim in a slip or skid, pitch excursions > are also induced as a result of the canted tail rotor and downwash on the stabilator.
Lateral accelerometers sense this out of trim condition and signal the stabilator amplifiers to compensate for the pitch attitude change (called lateral to sideslip to pitch coupling).
Nose left (right slip) results in the trailing edge programming down. Nose right produces the opposite stabilator reaction.
If the stabilator drives down, this will make the nose go down further.
I know I'm missing something big here but can't put it together.
