You think l-UAL pilots were not given adequate training on CCS or the new PBS, you should have tried to be a "new" CAL pilot. New hires are given slightly above zero training in both. When the trainers in the domiciles go away, hopefully ALPA will require some kind of adequate training for new hires, as some of them have never even heard of PBS.

I have been continually surprised at the acceptability of inadequacy on the lCAL side.

Like others have said, "that is all they know."
