TheiC - Ha ha. 200 kgs for us LCC operators is the luxury of once around the hold! Methinks we operate in different 'fuel environments'!
de facto - Yes, all was normal: engines performed correctly and we didn't 'lose' the fuel. In fact, the flight record shows we made fuel savings on that sector.
its easy - You had the same reaction from engineers as I did, though they were intrigued by the occurrence. As others have said, and Barkingmad has suggested, there a number of factors that can influence fuel gauge readings which don't demand detailed investigation.
The phantom centre tank fuel merely intrigued me further and I wondered whether there was some connection and possible technical explanation.
Barkingmad - the views across the Alps yesterday were truly picturesque and although I kept one eye on the gauges and spared a thought for SOPs my true focus was out the window.
