I thought that manual fuel management went out with Lindbergh, does the Vixen really require the pilot to manually select tanks, anyone know ?
Well no (you are thinking incorrectly:-) - e.g. look up the Clutha Bar Police helicopter crash only the other year.

Has a summary.

Full report.
From memory:- Helicopter with fuel on board and with no evidence of fuel supply system faults (pumps or valves or pipes) fatally crashed due to the engines not being supplied with fuel.
Switchology issue?
Possible issues with some of the 4 fuel level sensors?
