Which battery provides power for engine start in the Pilatus PC-12 NG?

• A. Bat 1
• B. Bat 2
• C. Both batteries
• D. Neither battery

Answer: (B)

The Pilatus PC-12 NG is equipped with two batteries, but for engine start, the primary power source is Battery 2. This battery is typically designated as the start battery and is designed to handle the high current demand required during the engine starting process. Battery 1 serves various systems, including avionics and other electrical loads during normal operations, but it does not directly initiate engine start. In this aircraft, Battery 2’s capacity and design are optimized for delivering the necessary power for starting the engine, ensuring that the aircraft can reliably start even under various conditions. Understanding the role of each battery in the system helps with troubleshooting and operational effectiveness during flight operations.
