Which system is primarily responsible for operating the helicopter's flight controls in the event of a hydraulic failure?

• A. Mechanical backup system
• B. Emergency power supply
• C. Electrical system
• D. Redundant hydraulic system

Answer: (D)

The system responsible for operating the helicopter's flight controls in the event of a hydraulic failure is the mechanical backup system. This system is designed to provide a secondary means of control when the primary hydraulic system is compromised. In helicopters, the flight control system often relies on hydraulic systems to move control surfaces, making it critical to have a backup in case of a failure. The mechanical backup allows pilots to maintain control over the aircraft's flight path even when the hydraulic pressure is lost. This is often achieved through direct linkage mechanisms that bypass the hydraulic systems, ensuring that the aircraft remains controllable and safe to operate. While a redundant hydraulic system might seem like a reasonable choice, its purpose is to enhance reliability rather than serve as a means of control in failures. The emergency power supply is typically for electrical functions and would not suffice for flight control, and the electrical system generally powers avionics and other non-control related functionalities. Thus, the mechanical backup system is essential for maintaining operational control of the helicopter in the face of hydraulic issues.
