Force Trim System

The Force Trim System is a magnetic brake system which holds the cyclic in position when activated. Force Trim does not affect the pedals or collective. Force Trim can be activated by the Force Trim Switch on the SCAS Control Panel, and can be interrupted using the Force Trim Interrupt Switch on the Pilot or Copilot Cyclic Grips to provide a new reference point.

Stability and Control Augmentation System

The Stability and Control Augmentation System (SCAS) is a flight control augmentation system that works in three channels – pitch, roll and yaw. SCAS improves flight handling qualities and reduces pilot workload by assisting desired response characteristics and damping external helicopter inputs. The system also includes a Heading Hold Mode (HHM).
