Pointing out the WOCL flying we already do isn't justifying CDOs, it's discounting the argument that we shouldn't do CDOs for safety reasons. That isn't the same thing. CDOs are undesirable flying. That's a pretty good reason not to do them. You don't have to be sensational to have a good argument. "CDOs are unsafe" is a bad argument unless you can provide some sort of evidence. There are countless airlines who do CDOs with FOQA and ASAP programs. I've never seen any data that indicates CDOs are unsafe. That data might exist. Find it and post it and I'll agree with you.

FAA definition


Being tired isn't the same as being fatigued. I fly tired all the time and I suspect everyone here does too. Yawning doesn't affect my ability to pilot an airplane.
