Which battery is associated with the "HOT BUS"?

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

Answer: (A)

The "HOT BUS" is associated with Battery 1. This term refers to an electrical distribution feature in the Pilatus PC-12 NG that allows certain essential systems to remain powered even if the aircraft's main battery power is disconnected. Battery 1 is configured to supply power to the HOT BUS, ensuring that critical functions, such as emergency lighting and some avionics, receive power independently of the rest of the electrical system. This design is particularly crucial for maintaining functionality during emergencies or when the main battery system is compromised. Battery 2, while also important in the aircraft's electrical architecture, does not supply power to the HOT BUS; instead, it primarily serves as a backup. Understanding the role of Battery 1 in relation to the HOT BUS is essential for managing the aircraft's electrical systems effectively during operations.
