Fatigued vs intoxicated
Fcu agree with your points. However it's never that clean cut. If we look at the Ups crash at Birmingham USA . Airlines and union get thrown out of FAA enquiry. Airline says self management of rest. Union says regs. In the Uk there are an average of 8 road deaths a year maybe four sleepiness affected. In the plane two crew, technical systems, sops being a defense against fatigue , Atc and so on. In truth airlines are doing more about fatigue than ever before, some I admit don't seem to involve crew in the process and many do a half job but overall it's moving in the right direction
