What is the primary source of DC power during normal operations of the TH-73A?

• A. Starter generator
• B. Auxiliary generator
• C. Battery
• D. Inverters

Answer: (A)

The primary source of DC power during normal operations of the TH-73A is the starter generator. The starter generator is designed to serve dual functions; it provides the initial power to start the engine and continues to supply electrical power during flight operations. Once the engine is running, the starter generator operates to recharge the battery and supply the necessary electrical power for avionics and other systems. While batteries are crucial for starting the engine and providing power when the aircraft is on the ground or when the starter generator is not operational, they are not the primary source of DC power during flight. Auxiliary generators and inverters also play roles in powering different systems, but they do not serve as the main supplier of DC power during normal operations; instead, they complement the capabilities of the starter generator.
