The HeliSAS autopilot was developed specifically for light helicopters. In its primary mode, the autopilot functions as a stability augmentation system by applying corrective inputs to the cyclic in order to maintain fixed pitch and roll attitude. Only light force on the cyclic is required to override or “fly through” the system. Additional autopilot modes include heading hold, altitude hold, navigation signal tracking (VOR or GPS) and approach navigation (including vertical guidance). The autopilot does not provide collective or pedal inputs.
