Which generators are driven from the left engine?

• A. Generators 1 and 3
• B. Generators 2 and 4
• C. Generators 1 and 2
• D. Generators 3 and 4

Answer: (A)

The left engine powers the two generators mounted on its accessory gearbox. In this design, each engine drives two generators, giving four in total, with the left engine feeding the two left-side generators and the right engine feeding the two right-side generators. This setup provides redundancy and balanced electrical load, so even if one generator drops out, the remaining generators on either side can still supply power to the essential buses. So, the generators driven by the left engine are the two on the left side.
