What type of electrical system does the Pilatus PC-12 NG utilize?

The Pilatus PC-12 NG utilizes a 28 Volt DC electrical system. This design choice is significant because a 28 Volt system provides an efficient balance of power and weight while allowing for the operation of a wide range of aircraft systems.

A 28 Volt DC system is commonly used in aviation since it offers advantages such as reduced weight compared to higher voltage systems and lower electrical losses. Additionally, the components used in a 28 Volt system are typically robust and designed to handle the demands of an aircraft environment, contributing to the reliability of the electrical system necessary for various onboard functions, including avionics, lighting, and power management for critical systems.

In other contexts, different voltage systems may be found, such as 14 Volt systems often used in smaller general aviation aircraft. However, the choice of 28 Volt in the Pilatus PC-12 NG aligns with the operational requirements and functionalities expected in a modern turboprop aircraft, ensuring both efficiency and dependability in its electrical system design.
