You’d have to assume it’s far more convenient to leave with a full fuel load rather than pay Tasmanian prices for a refill.
Theres no point suggesting who / what is responsible for winding it to the left because it is irrelevant if it was missed before takeoff. All that would do is incriminate additional parties and not affect the outcome other than from a possible litigation perspective, despite that being a hard ask.
Can anyone think of an operational reason as to why it would be so far across, perhaps from a previous flight?
Does anyone know if the type certificate requires demonstration that the aircraft is controllable with full rudder trim?
I guess it’s a moot point if it was over weight. All bets would be off on certification requirements.
