Scuffers;

Yes, BUT as people keep saying, that's just one warning, what about all the indications/warnings before this?
awblain;

While the warning about fuel was logged in the computer, is it clear that the warning was actually displayed on the display?

Is it yet clear what was displayed/annunciated/chimed? Not in time, but in total?
In the report, that I'm sure you both must have read it says;

"The Warning Unit has provided information on the order in which warnings were triggered during the flight but not when they occurred. The unit recorded the normal warnings associated with starting the helicopter, followed by a warning free status. It subsequently recorded intermittent LOW FUEL 1 warnings for the left fuel supply tank, then a permanent LOW FUEL 2 warning for the right fuel supply tank. This was followed by a further temporary LOW FUEL 1 warning, before it became permanent for the remainder of the flight. These LOW FUEL warnings are triggered by thermal sensors in the supply tanks.
.
.
An alarm gong was also recorded followed by intermittent warnings relating to low rotor rpm. The penultimate warning recorded related to the battery discharging, which occurs when there is insufficient engine-driven generator power. The last warning related to an autopilot system failure. Investigation into the possible causes for the individual warnings is continuing.
"

However as you must have clicked on a link to the report, that I'm sure you both must have read, you must already know that, so what was the question?
