unworry, interesting follow up info, thank you. I've never heard of this (can't say I've looked hard). I would be really very interested to see just how hard this is being pursued by the various regulators & operators.
I've seen just how much foot dragging & delays there has been implementing the FRMS under CASA, and as I best I can determine there is no proposal for any clinical testing in the new fatigue management system. Sounds like there should be.
