NEVER EXTEND!
The rules are written already beyond the accepted scientific limits for human performance. When you extend you truly go out into no mans land.
Interested in the conclusions of your thesis, Leaf.
I operate to the High Capacity CAO48 exemption, and there have been times when I've extended and felt fine, and other times when I have been well inside limits and felt fatigued.
I do feel that the exemption is not very scientific and can lead to fatigue especially when it starts to be regarded as a target rather than a limit (which seems to be a global trend). So far the only effect of FRMS in my operator is that fatique is supposed to be reported and monitored, otherwise it's business as usual. I don't think it's working very well as there appears to be a reluctance from most pilots to report for whatever reason.
Care to share more of your thesis?
