Which gearbox drives the No. 3 VFG?

The No. 3 Variable Frequency Generator (VFG) is driven by the Left Turbine Accessory Gearbox (TAGB). This gearbox is designed to provide power to various engine accessories, including the VFGs, and is crucial for ensuring that the electrical systems receive the appropriate power from the aircraft's engines.

Understanding this configuration helps in grasping how the aircraft's electrical generation system is organized and ensures that power is distributed efficiently throughout the aircraft systems. The Left TAGB's role in driving the No. 3 VFG highlights the division of power management responsibilities among the gearboxes, optimizing performance and reliability. This organizational structure in the gearbox system is critical for the smooth operation of all electrical components.
