It was calculated that, as the helicopter approached Bothwell, the
low fuel warnings began. The pilot was presented with an intermittent
low fuel 1 warning, which became permanent, and a low fuel 2 warning.

heard by all members of the crew. The warnings were acknowledged and, once permanent,
continued to illuminate for the remainder of the flight.
