What's this? You either have an instrument rating or you don't.
It's a type rating restriction that the FAA started requiring sometime after I took my last rating ride in 1986.
If you don't demonstrate to proficiency CTL during the rating ride then your type rating states (words to this effect) "Circle to land NA on A330" or such.
The carriers that are members of the "1,000 and 3" club don't want to train for something their crews are not going to use.
