Buzzbox - I do not agree with your analysis of Glofish's post - what seems to be filtering out here, and hinted at by you, is that given the understandable lack of 'handling' by long-haul crews an ETOPS diversion on near min fuel plus a subsequent g/a, all flown under a stressful situation, carries a high probability of an accident in the ensuing visual circuit and that it seems to be agreed that at the end of a long flight, a visual is not the desired approach as it is really not safe to expect a 'tired' crew to execute one. So be it, if true.
Surely then the regulations need to change to require
a) Extra ETOPS div fuel to allow a second coupled approach at the alternate
b) A mandatory coupled approach on arrival at dest (or div if required to achieve) on a long-haul sector as defined by over xxxx hours or by circadian factors
If that is what we need, that is what we need. Let's not just pussy-foot around talking about the bunnies being 'tired' and having body clock problems and 'slam-dunking' around the sky - adjust the ops to cope?
