And did you rely on the other fuel gauges to determine how much fuel you considered was remaining in the tanks?
Didn't have to. I was in the circuit and about to land. The gauge for one tank suddenly dropped from the reading that coincided with the calculated consumption to a reading of zero, because of (what turned out to be) a wiring problem. I knew that the tank had not suddenly lost a quarter of its contents and I wasn't running on that tank anyway. If everything dropped to zero and it turned out those indications were accurate, my only option would have been to ..... do what I was already doing.
As to whether the report serves its purpose, unnecessary waffle distracts and therefore detracts from the effectiveness of safety messages.
