14 DME, 4300', 230kts, or even 250kts, is now being presented as some sort of tricky arrival?
It isn't. Period. Routinue arrival trying to save time is 250kts to 10 DME @3000'.
And every long haul crew is tired. Most are lucky if they get 2 hrs of sleep during a long haul overnight flight. Three hours of sleep, unless on a four man crew, is rare.
Four man crews are the most rested. Asiana was a four man crew.
