TH-73 Helicopter Systems Practice Test 2025 – Complete Exam Prep

The correct type of battery used in the TH-73 system is the nickel cadmium battery. Nickel cadmium batteries are known for their robustness and ability to deliver high discharge rates, which is an important characteristic in aviation applications where reliability and performance are critical. These batteries can function effectively in a wide range of temperatures, making them suitable for the various operating conditions encountered during flight training operations.

Additionally, nickel cadmium batteries have a long service life and can withstand numerous charge and discharge cycles without significant degradation. This reliability is particularly essential in training environments where consistent performance is needed to ensure safety and effectiveness in training scenarios. Their lower energy density compared to some newer battery technologies also allows them to be relatively compact while providing the required power output.

Other battery types, such as lithium-ion, lead-acid, and alkaline, may have their own benefits but do not possess the same balance of durability, discharge capabilities, and charging efficiencies that are preferred in the context of helicopter systems like the TH-73.
