it's all about duty in, duty out, and what is involved, no exceptions.
Hello, I'm now at work and starting to get my act together for the purpose of accepting a flight = now on duty.
Goodbye, I'm now done with all that stuff and going out the door = now off duty, see you in 10, or 11, or whatever.
I love it when the operator says the first 15 minutes of preparation to accept a flight at the start of a shift is not duty, but industry standard.
Where's that in the regs? And just how does one get everything done, in 15 minutes?
For the most part I just ignore the company trying to chip away at the regs. I pay attention to the FAA because they own the regs and have the bigger stick, much bigger.
