Helicopter autopilot HFC-100

dual-axis

The Cool City HFC-100 Helicopter Flight Control System is the ultimate in two axis autopilot (AP) and stability control and augmentation systems (SCAS). Consisting of a two-axis (roll/pitch) rate-based SCAS and two-axis (roll/pitch) rate/attitude based AP, the HFC-100 brings unparalleled performance and safety to light and medium sized rotorcraft at a fraction of the cost of systems that were designed many years ago. Included in the HFC-100, a rate-based Stability Control and Augmentation System improves basic rotorcraft stability and reduces the high-rate perturbations encountered in turbulence. The SCAS series actuators, installed in the rotorcraft’s primary control tubes, are very high-rate, low authority, electromechanical actuators. The actuators operate with approximately 10% control travel authority and take less than a second to move full actuator travel. For unquestioned safety, the actuators have internal electrical and mechanical stops. Operation of the Cool City SCAS is approved throughout the full flight envelope, from start-up to shut-down, and is virtually transparent to the pilot. The SCAS System improves rotorcraft safety by reducing pilot workload and fatigue, while improving the quality of ride for all occupants.
