Sounds like skrangerpro and FlightSpanner above have put a time and position on the transfer switch error. The radar flight path shows a zigzag over Dalkeith and the main tank level was low enough to get transfer pump warnings.
Henry: Is this strictly true? I've read this thread and the EC135 thread particularly post 83 and I've seen slightly conflicting views on the fuel level at which transfer pump warnings appear, hence my earlier question.
I think the position has been worked back from the endurance of the supply tanks once they are no longer being replenished by either i) overall fuel level above the fence, ii) sloshing over the fence or iii) transfer pumps operative.
