Stabilator components1

Stabilator Components


Stabilator functions s c a l p

Stabilator FunctionsS.C.A.L.P.

  • Sideslip to Pitch coupling

  • Collective Coupling

  • Angle of Incidence Decreased w/ Increased Airspeed

  • Low Speed Flight it Aligns w/ Rotor Downwash

  • Pitch Rate Feedback


Stabilator malfunctions

Stabilator Malfunctions

  • STABILATOR MALFUNCTION - AUTO MODE FAILURE

  • UNCOMMANDED NOSE DOWN/UP PITCH ATTITUDE FAILURE.
