Which two components are critical to the TH-73A's electrical system?

• A. Generator and battery
• B. Switch and fuse
• C. Alternator and inverter
• D. Wires and connectors

Answer: (A)

The generator and battery are fundamental to the TH-73A's electrical system because they are responsible for providing and storing electrical power necessary for the operation of various aircraft systems. The generator produces electrical power while the aircraft is in operation, ensuring that all systems receive the necessary voltage and current. The battery acts as a backup power source, allowing the aircraft to start and maintain power during situations where the generator is not available or functioning properly.

By ensuring a reliable power supply to essential systems such as avionics, lighting, and engine control, the generator and battery enable safe operation and performance of the aircraft. Their collaborative function is vital to the aircraft's overall electrical integrity, making them critical components. Other components, while important, do not play as central a role in the fundamental operation of the aircraft's electrical system as the generator and battery.
