Which components are driven by the MWGB?

The correct response identifies the components driven by the Main Gearbox (MWGB) accurately. In this case, the MWGB is responsible for providing mechanical power to various components, which in this scenario includes the No. 4 Variable Frequency Generator (VFG), the No. 1 Constant Frequency Generator (CFG), the No. 3 Hydraulic Pump, and the MWGB oil cooler.

In a helicopter's mechanical system, the MWGB plays a critical role by allowing the engine's power to be distributed effectively to multiple systems that support the aircraft's operations. The inclusion of both generators and hydraulic pumps demonstrates the MWGB's versatility in driving essential electrical and hydraulic systems, which are vital for the proper functioning of the aircraft during flight.

For instance, the generators are crucial for providing electrical power to the aircraft's systems, while the hydraulic pump is needed for operating various flight control surfaces and landing gear, among other functions. The MWGB oil cooler is included as maintaining appropriate oil temperature is essential for the lubrication and functioning of the MWGB, further illustrating the integrated nature of these components.

This choice exemplifies how interconnected the various systems are within the helicopter, showcasing the MWGB's integral role in the overall functionality and efficiency of the aircraft's operation.
