helicopter automatic flight control system

Since most Part 27 aircraft are not equipped with even the most basic stabilization systems, they remain more susceptible to loss of control. This restricts such aircraft from operating under instrument flight rules and results in more frequent flights under VFR conditions in the midst of poor visibility and low ceilings. Consequently, these smaller rotorcraft lack the operational capability and inherent safety that autopilot systems provide. However, most of these systems are too complex or heavy to integrate into Part 27 helicopters, particularly single-engine models. “Aircraft stability would help a pilot maintain positive aircraft control during temporary losses of visual cueing or disorientation.”Īutomatic flight control systems have been successfully integrated into transport category (Part 29) helicopters for more than 30 years and have proven their effectiveness and safety for flight in low visibility and instrument meteorological conditions. “If light helicopters operating under visual flight rules could be enhanced to meet some of the instrument flight rule stability requirements, many loss-of-control accidents could be avoided,” explains Nick Mayhew, industry co-chair of the U.S. In response, the USHST is moving forward with some first steps to increase safety by encouraging the development and installation of stability augmentation systems and autopilot devices that increase the flight stability of light helicopters. Current light helicopters have flight characteristics that are challenging and demanding of pilot workload.

Helicopter Safety Team determined that loss of control while in flight has been a leading factor in accident causes, especially involving light helicopters. As a result of its comprehensive analysis of fatal helicopter accidents, the U.S.
