Which generators are driven from the right engine?

Which generators are driven from the right engine?

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

Answer: (A)

The engine-mounted electrical system uses two generator units per engine, driven through the engine’s accessory gear box. The numbering is paired with the engine location: the left engine powers generators 1 and 3, while the right engine powers generators 2 and 4. So the generators driven from the right engine are the two on that side, numbered 2 and 4. This arrangement provides redundancy and allows cross-connecting to essential buses if one side or the other has an issue.
