Stilton, aiming point
Well, yes, but......
Both issues are relevant, but do we REALLY want to tolerate FUI (Flying Under the Influence).
I'm frequently disturbed by a laissez-faire attitude in some of these forums, along the lines "It hasn't hurt anybody yet, so what's the deal"
Performance-degrading substances and the operation of machinery don't mix. Same goes for fatigue.
This isn't a trade-off and I can't for the life of me understand the significance of the reference to political correctness.
If you've been following the Ryanair thread, you'll see that the forced tolerance of fatigue is driven by shareholder value......
