I travel regulary to the Solomons because of interests there. It may help the argument if it is realised that the Twin Otter operation is using two pilots, they only fly in daylight although there is a bit of weather occasionally, especially in the afternoons a-la PNG. None of the pilots I've spoken to mentioned flying 120 hours in a month however 100 hours isn't uncommon. There is one pilot currently on a break for having reached 900 hours, but I'm told he took 10 months to reach that figure.
