Chrome, that does not sound right.
After the incident I did have a re-read of the bulletin to get answers. It really doesn't explain my experience does it. 10 years on the bus, I have never seen it before. I even flew the same aircraft the very next day, it didn't reoccur.
Chrome, With my electronics hat on, my guess would be a bad connection somewhere in the FQI system.
What was also different was that the fuel temperature in all tanks were above 20°C at FL360. That could be the explanation.
