A TRU Dilemma
“ While en route”¦I as the Pilot Not Flying /Pilot Monitoring, noticed a message that said TRU2 on my PFD [Primary Flight Display] and on my MFD [Multi-Function Display]. I looked over to my Captain’s side, the Pilot Flying, and saw his [display] said TRU1. I knew this was not normal so I asked him about it. Both the Captain and I thought that it was referring to the Transformer Rectifier Units (TRU) in the electrical system. We brought up the electrical page to monitor TRU1 and TRU2. Both looked fine. We got out our POM [Pilot Operating Manual] and contacted Dispatch and Maintenance Control to see if we could find out what it means, as neither of us had seen that displayed before. The plane seemed to be acting fine so we continued to our destination. While on approach we noticed the TRU1 and the TRU2 message was blinking. When we switched from the FMS to ILS, we noticed a difference in course and also in heading…We were in IMC and in mountainous terrain”¦.
What would you have done?
A Transformer Rectifier Unit (TRU) is a device for converting alternating current (AC) input of one voltage into direct current (DC) output of another voltage.
