If one generator fails, what happens to the electrical load?

If one generator fails, what happens to the electrical load?

• A. The aircraft loses all power.
• B. The remaining generator automatically shuts down.
• C. The remaining generator can carry the entire electrical load of the aircraft battery.
• D. The battery is disconnected.

Answer: (C)

With two generators, the electrical system is designed for redundancy and load sharing. If one generator fails, the remaining generator is capable of supplying the entire electrical load the aircraft requires, within its rating, while the distribution system automatically reconfigures to keep power on to all essential systems. The aircraft battery still provides starting power and emergency support for a short period, but it does not become the primary source to drive the full load continuously. That’s why the remaining generator carrying the entire electrical load is the correct outcome.
