The Altitude Hold, Hover Stabilization and Auto Pilot (AHHS-AP) System provides a low-cost solution for reduced pilot workload, increased flight safety, improved operational capability, and situational awareness particularly during low visibility conditions.
The AHHS-AP provides hands-free cyclic and collective control for cruise, automatic approach, low-altitude hover operations, precision hover and drift control, automatic descend to land, and automatic go-around. AHHS-AP delivers precise control capabilities that allow aircrews to safely operate in environments that would otherwise be impossible, such as brownout/whiteout conditions, overwater hover operations, and tight landing zones. AHHS-AP integrates with the aircraft’s existing flight control systems and is capable of interfacing with a myriad of on-board sensor inputs including barometric and radar altimeters, navigation and flight management systems, embedded GPS/INS, accelerometers, gyros, and data bus architectures.
Leonardo DRS has over 25 years of experience in development, integration, production and sustainment of AHHS systems, with proven performance around the globe. The result is an efficient, cost-effective solution that significantly enhances flight safety and operational capabilities, making it the after-market flight control enhancement system of choice on special operations and combat rescue helicopters.
