What does the acronym TRU stand for in aviation?

In aviation, the acronym TRU stands for Transformer Rectifier Unit. This device is crucial in converting alternating current (AC) from the aircraft's generators into direct current (DC) to power various electrical systems and components within the aircraft. The operation of the TRU is essential for maintaining a stable power supply, as many avionics and electronic systems require DC power for proper functioning.

The TRU's ability to provide regulated DC voltage ensures that sensitive equipment operates reliably, promoting safety and efficiency in aircraft operations. Understanding the role and function of the TRU is fundamental for aviation maintenance personnel, as it directly impacts aircraft performance and safety.
