Yeah I just pulled up some of my regional buddies on the airman cert branch website and all of theirs say:
"CL-65 circling approach VMC only
ATP circling approach VMC only"
Oh and it isn't just on the CL-65. I have friends flying the ERJ 145, 170/190, A-310, 757/767 and they all have that limitation on their type. As
@NJP_MAN said, if you didn't do it in the training, you don't get it on the type. If you do your ATP in say a Seminole or Seneca and actually do a circling approach, then you don't have that ATP circling restriction. I know a lot of the foreign airlines want that removed if you go overseas.
