Where is the power management unit (PMU) located?

The power management unit (PMU) is located underneath the engine in the accessory compartment because it plays a critical role in regulating the electrical systems of the aircraft, ensuring that the power distribution is managed effectively. This location is strategic, allowing the PMU to connect directly to the engine systems while also being accessible for maintenance and monitoring.

The PMU is designed to control various functions such as power generation and distribution, which are integral to the operational efficiency of the aircraft. Its placement in the accessory compartment ensures that it is exposed to optimal conditions necessary for effective functioning. Additionally, being situated near the engine supports the PMU's ability to monitor and react to engine performance, adjusting power output as needed to maintain safe and efficient flight operations.
